Foam Pump: Everything Brands Need to Know
Foam pumps deliver 0.12 ml liquid per stroke at 5:1 air-to-liquid ratio — concentrated formulas above 8% active surfactant clog the 200-mesh screen within 30 strokes; dilution before filling is mandatory.
Foam pumps are deceptively simple to specify and surprisingly easy to get wrong. The mesh screen that creates the foam, the air-to-liquid ratio, the formula viscosity limit, and the neck size compatibility all interact in ways that aren’t visible from a product catalog. This guide gives brands a complete technical and commercial framework — drawn from SUNSHINE’s Ningbo foam pump production line — to specify, sample, and source foam dispensers correctly the first time.
The premise of a foam pump is elegant: take a diluted soap formula, combine it with air inside a two-chamber pump, force the mixture through a fine-mesh screen, and deliver rich foam directly to the hand — no rubbing required, no formula wasted. Brands love foam dispensers because they deliver a perceptibly premium experience at a fraction of the product cost per use (a 0.12 ml liquid dose creates a 0.6 ml foam dose, so each press consumes 70–80% less formula than a lotion pump delivering the same volume). Consumers love them because they feel luxurious and rinse quickly.
The trouble starts when brands specify a foam pump for the wrong formula, the wrong bottle neck, or the wrong output volume — and discover it at filled-bottle QC rather than at the sampling stage. SUNSHINE manufactures foam pumps in 24/410 and 28/410 neck sizes across PP construction, with monthly production capacity of 300,000 units and 6 surface finish options. The following sections draw on that production context.
How a Foam Pump Works: The Two-Chamber Mechanism Explained
Unlike a lotion pump — which simply pressurizes liquid through a single chamber — a foam pump uses two separate chambers that work in tandem on every actuation stroke. Understanding this mechanism lets you evaluate a foam pump sample before accepting it and explain to your filler what setup the pump requires.
| Component | Function | Critical Spec | SUNSHINE Standard |
|---|---|---|---|
| Liquid Chamber | Draws formula from bottle via dip tube; delivers a precise liquid dose per stroke | Liquid volume: 0.10–0.15 ml/stroke (determines formula per use) | 0.12 ml/stroke standard |
| Air Chamber | Draws ambient air from above the liquid level; compresses it alongside the liquid dose | Air-to-liquid ratio: 3:1 to 10:1 (determines foam density) | 5:1 standard (moderate density foam) |
| Mixing Chamber | Combines compressed liquid + air immediately before the mesh screen | Chamber geometry determines homogeneity of foam bubbles | PP construction |
| Mesh Screen (Net) | Forces the air-liquid mixture through a fine net; bubble size is determined by mesh count | Mesh count: 100–300 mesh nylon or polyester; finer mesh = smaller bubbles = denser foam | 200-mesh nylon standard; 300-mesh on request |
| Piston Assembly | Actuates both chambers simultaneously on downstroke; spring returns on release | Actuation force: 3–6 N (lighter than lotion pump) | 4 N standard PP spring |
| Spring | Returns piston; determines return speed (affects foam delivery rate) | PP spring (all-plastic) or SS 304 spring; PP preferred for all formulas | PP spring standard on foam pumps |
| Dip Tube | Draws liquid from bottle bottom; must reach within 5 mm of bottle base | Length tolerance ±5 mm vs bottle depth; HDPE or PP construction | PP dip tube; cut-to-length on request |
The air-to-liquid ratio is the single most important specification for foam quality — and the one most brands never put in their purchase order. A 3:1 ratio produces a light, airy foam (suitable for shampoo applications). A 7:1 ratio produces a dense, cream-like foam (suitable for face wash and hand soap). A 10:1 ratio produces a meringue-stiff foam that feels premium but can be slow to rinse — right for a luxury face cleanser, wrong for a quick-rinse hand soap in a food service setting. Request the air-to-liquid ratio explicitly at the sampling stage, not after tooling is approved.
Foam Pump vs Lotion Pump vs Liquid Soap Dispenser: Which to Choose?
The three most common hand and body dispensing formats — foam pump, lotion pump, and conventional liquid soap dispenser — are often treated as interchangeable by brands, but they have fundamentally different formula requirements, consumer use patterns, and cost-per-use economics. Choosing the wrong one means either under-delivering on the consumer experience or burning formula cost unnecessarily.
| Criterion | Foam Pump | Lotion Pump | Liquid Soap Dispenser (push) |
|---|---|---|---|
| Mechanism | Two-chamber: liquid + air → mesh screen → foam | Single-chamber: liquid pressurized → direct dispense | Single-chamber: liquid gravity + press |
| Formula viscosity | Low: 200–2,000 cPs max; diluted surfactant (2–20% active) | Medium-high: 500–50,000 cPs; full-concentration formula | Low-medium: 100–5,000 cPs; watery to thin lotion |
| Output per press | 0.4–0.8 ml foam (from 0.10–0.15 ml liquid) | 0.5–4.0 ml liquid | 1.0–3.0 ml liquid |
| Formula cost per use | Lowest — 70–80% less liquid per wash vs lotion pump | Highest — full formula concentration per dose | Medium — full concentration, higher volume |
| Rinsability | Fast — foam dilutes instantly under water | Slower — thick formula requires rubbing to lather | Medium — thinner formula rinses faster than lotion |
| Consumer perception | Premium, luxurious; associated with professional products | Standard; familiar across hand and body care | Functional; low perceived value vs foam |
| Fill line compatibility | Requires low-viscosity formula; pre-diluted at fill stage | Standard fill for any viscosity | Standard fill |
| Neck size (SUNSHINE) | 24/410, 28/410 | 24/410, 28/410, 28/412 | 28/410, 38/400 (varies) |
| MOQ (SUNSHINE) | 10,000 pcs | 10,000 pcs | 10,000 pcs |
The formula dilution requirement is the most common surprise for brands switching from lotion pump to foam pump: your existing 20% surfactant hand wash concentrate cannot go directly into a foam pump bottle. It must be diluted to 2–8% active surfactant concentration first. Some brands pre-dilute at the factory before filling; others reformulate specifically for foam pump delivery. Either approach is valid — but it must be decided before ordering the foam pump, because a concentrated formula in a foam pump will clog the mesh screen within 30–60 strokes.
For a detailed technical and commercial comparison of these two formats, see our in-depth guide on when to choose foam dispensing over a lotion pump — which covers the formula reformulation cost, consumer testing methodology, and switching economics in depth.
The Mesh Screen: How Net Count Determines Foam Quality
The mesh screen (also called the net, foam net, or filter screen) is the most technically critical component in a foam pump — and the most frequently under-specified. Every bubble in your foam is the product of one pore in this screen. Mesh count, material, and condition at filling all determine whether your product delivers a consistent, luxurious foam or a sputtering stream with large bubbles.
| Mesh Count | Bubble Size | Foam Texture | Best Application | Formula Viscosity Limit |
|---|---|---|---|---|
| 100 mesh | Large (0.5–1.0 mm) | Light, airy, fast-collapsing | Hair shampoo, rinse-off shower gel | Up to 3,000 cPs |
| 150 mesh | Medium (0.3–0.6 mm) | Moderate density; good for household hand soap | Hand soap, kitchen cleaning foam | Up to 2,000 cPs |
| 200 mesh (standard) | Fine (0.15–0.3 mm) | Dense, stable, cream-like; stays on hand 20–30 sec | Hand soap, face wash, baby foam cleanser | Up to 1,500 cPs |
| 300 mesh | Very fine (<0.15 mm) | Ultra-dense, mousse-like; slow to collapse | Luxury face cleanser, prestige hand soap | Up to 800 cPs (very diluted formula) |
SUNSHINE’s standard foam pump uses 200-mesh nylon screen — the industry consensus for balanced foam density and formula compatibility across hand soap and face wash applications. The 300-mesh option is available on custom order, adding 7–10 days to standard lead time for screen sourcing and assembly validation.
Screen degradation is a real-world quality risk that most brands don’t test for: over 10,000 actuations, a nylon screen at 200 mesh will show approximately 3–5% pore enlargement from mechanical fatigue, slightly coarsening the foam texture. SUNSHINE’s foam pump screens are validated at 10,000 actuations with less than 5% pore size change — sufficient for a full 500 ml bottle of hand soap used daily for 12 months. For a detailed technical explanation of the mesh screen mechanism and how it creates stable foam, see our guide to how the foam pump mesh screen works.
Foam Pump Size Guide: 28/410, 43/410 and Neck Compatibility
Foam pumps use the same GPI thread notation as other dispensing closures: neck diameter (mm) / thread profile. However, foam pumps have a unique sizing consideration — the pump body diameter must be large enough to house both the liquid chamber and the air chamber side-by-side, which means foam pumps tend to be physically larger than lotion pumps on the same neck size. A 28/410 foam pump body is typically 32–34 mm in outer diameter, which may not fit through the opening of a narrow bottle even if the thread fits.
| Size | Neck OD | Bottle Format | Output Range | Typical Application | SUNSHINE SKU |
|---|---|---|---|---|---|
| 24/410 | 24 mm | 200–400 ml slim or oval bottles; countertop hand soap | 0.4–0.6 ml foam/stroke | Premium hand soap, face wash, baby care | WP-1391 (24/410–28/412) |
| 28/410 | 28 mm | 250–500 ml standard round bottles; bathroom & kitchen | 0.5–0.8 ml foam/stroke | Hand soap, shower gel, shampoo, kitchen foam | WP-1393 (28/410) |
| 28/412 | 28 mm | 250–500 ml professional/salon format | 0.5–0.8 ml foam/stroke | Salon shampoo, professional cleanser | WP-1391 (24/410–28/412) |
| 43/410 | 43 mm | 500 ml–1 L wide-mouth refill containers | 0.8–1.2 ml foam/stroke | Commercial hand soap, institutional hygiene | Custom — quote required |
Formula Compatibility: What Formulas Work in a Foam Pump
Formula compatibility is the most common cause of foam pump failure in market — not pump defects. A foam pump is not a universal dispenser; it works only with formulas meeting specific viscosity and surfactant concentration requirements. The following matrix covers the decision logic for personal care and household cleaning applications.
| Formula Type | Viscosity Range | Surfactant % (active) | Foam Pump Compatible? | Notes |
|---|---|---|---|---|
| Diluted hand wash / hand soap | 200–1,500 cPs | 2–8% active | Yes — optimal | Standard foam pump application; 200-mesh screen |
| Diluted face cleanser (foam type) | 500–2,000 cPs | 5–15% active surfactant | Yes — with testing | Run 30-day ICH stability at 40°C; check screen clog at day 10 |
| Diluted baby wash / baby foam | 200–1,000 cPs | 2–5% active (mild surfactants) | Yes | Use 200-mesh; specify hypoallergenic formula to SUNSHINE for compatibility check |
| Diluted shampoo (foam delivery) | 500–3,000 cPs | 5–12% active | Yes — 100-mesh recommended | Larger bubbles acceptable for hair application; 100-mesh reduces clogging risk |
| Concentrated hand wash (>15% active) | 3,000–15,000 cPs | >15% active | No — clog within 30–60 strokes | Must pre-dilute to <8% before filling; reformulation required |
| Body lotion / cream | >5,000 cPs | N/A (not surfactant-based) | No | Use lotion pump; foam pump physically cannot generate stable foam from cream |
| Micellar water / toner | <100 cPs | <1% surfactant | No | Too watery — air-liquid mixture won’t stabilize into foam; use mist sprayer |
| Household cleaning foam | 200–1,500 cPs | 3–10% active | Yes | Confirm chemical compatibility with PP chamber; avoid strong alkalis (>pH 11) |
The formula testing sequence before production commitment: (1) Fill 10 units with your formula; (2) Actuate 50 times and assess foam density, bubble size, and screen residue; (3) Leave filled for 7 days at 40°C and re-test; (4) Actuate 500 more times and check screen clog. This 4-step protocol catches 95% of formula compatibility issues before you commit to a production run. SUNSHINE will ship 50 sample units for formula testing within 10 days of order, with no tooling charge.
Output Volume and Foam Density: How to Specify What You Need
When specifying a foam pump for a new product launch, brands need to define three output parameters — not one. Most purchase orders specify only “foam pump 28/410” and discover the foam is too light, too dense, or delivers too much or too little product per press during consumer panel testing.
| Parameter | Definition | How to Specify | SUNSHINE Range |
|---|---|---|---|
| Liquid dose (ml/stroke) | Volume of actual formula delivered per press (not foam volume) | Specify in ml: “0.12 ml liquid per stroke” | 0.10–0.15 ml/stroke standard; 0.08 ml on custom |
| Foam volume (ml/stroke) | Volume of foam produced per press (liquid dose × air-to-liquid ratio) | Specify in ml: “0.6 ml foam per stroke” (= 0.12 ml liquid × 5:1 air ratio) | 0.4–0.8 ml foam/stroke at standard 5:1 |
| Foam density / stiffness | How firm and stable the foam is; driven by mesh count and air ratio | Request physical samples; compare to a reference product you like | Adjustable via mesh count (100–300) + air ratio (3:1–10:1) |
| Foam collapse time | How long the foam holds its structure on the hand before dissolving | Target 15–30 sec for hand soap; 30–60 sec for face wash | 20–25 sec standard 200-mesh at 5:1 ratio |
| Actuation force | Force required to press foam pump head | Specify max N for accessibility compliance: “≤5 N actuation force” | 3–6 N range; 4 N standard PP spring |
The most common specification gap is foam collapse time. A product intended for luxury face washing needs a foam that stays stiff for 45–60 seconds (allowing the consumer to work it into the skin before rinsing). A hand soap in a food service setting needs a foam that rinses in under 10 seconds (minimizing water waste and time). These two products need different mesh counts, different air ratios, and potentially different formula dilutions — specifying them both as “28/410 foam pump” without further detail produces the same pump for both, which is wrong for at least one.
Surface Finish and OEM Customization Options
SUNSHINE’s foam pump range offers the same six surface finish options as the disc cap and mist sprayer lines, enabling brands to create a visually consistent bathroom collection across all dispensing formats. The customization cost structure mirrors the other products: color and finish changes require no new tooling; output or mesh changes require minor tooling; new pump geometry requires full mold investment.
| Customization | Tooling? | MOQ | Lead Time | Cost Impact |
|---|---|---|---|---|
| Cap/collar color (PMS match) | No | 10,000 pcs | 20 days | +$0.002–0.005/unit |
| Smooth collar finish | No (stock) | 10,000 pcs | 20 days | Base price |
| Ribbed collar finish | No (stock) | 10,000 pcs | 20 days | Base price |
| Aluminum (anodized) collar | No | 10,000 pcs | +3–5 days | +$0.06–0.12/unit |
| UV coat (metallic lacquer) | No | 10,000 pcs | +5 days | +$0.05–0.10/unit |
| Water Transfer Printing | No (film setup only) | 10,000 pcs | +7–10 days | +$0.08–0.15/unit |
| Bamboo collar | No | 20,000 pcs | +10–15 days | +$0.15–0.30/unit |
| Mesh count change (100/150/300) | Yes — screen swap ($100–200) | 20,000 pcs | +7 days | Tooling one-time |
| Liquid dose change (0.08–0.20 ml) | Yes — liquid chamber retool ($200–400) | 20,000 pcs | +15 days | Tooling one-time |
| Logo deboss on actuator cap | Yes ($300–600) | 20,000 pcs | +10 days | Tooling one-time |
The all-PP construction (no stainless steel spring) is standard on SUNSHINE foam pumps — an important advantage over some lotion pump variants that use stainless steel springs. PP springs eliminate the only metal contact point between the pump internals and your formula, making the foam pump inherently more compatible with preservative-sensitive formulas and reducing corrosion risk for formulas with mild organic acids (pH 4–6 range, common in gentle face wash).
Application Guide: Hand Soap, Face Wash, Baby Care and More
Foam pump applications differ meaningfully in their mesh, output, and formula requirements. The application matrix below provides the key specifications for each category, matched to SUNSHINE’s available SKUs.
| Application | Formula Viscosity | Mesh Screen | Output / Stroke | Neck Size | Collar Finish | SUNSHINE SKU |
|---|---|---|---|---|---|---|
| Premium Hand Soap | 500–1,500 cPs; 5–8% active | 200 mesh | 0.5–0.6 ml foam | 28/410 | Aluminum, UV, Smooth | WP-1393 |
| Everyday Hand Soap | 300–1,000 cPs; 3–6% active | 150–200 mesh | 0.6–0.8 ml foam | 28/410 | Smooth, Ribbed | WP-1393 |
| Face Wash / Cleanser | 500–2,000 cPs; 5–15% active | 200–300 mesh | 0.4–0.5 ml foam | 24/410 | UV, Aluminum, Bamboo | WP-1391 |
| Baby Wash / Baby Foam | 200–800 cPs; 2–4% mild surfactant | 200 mesh | 0.4–0.5 ml foam | 24/410 | Smooth, Ribbed (simple aesthetic) | WP-1391 |
| Shampoo (foam delivery) | 500–2,500 cPs; 5–10% active | 100–150 mesh | 0.6–0.8 ml foam | 28/410 | Smooth, Ribbed, WTP | WP-1393 |
| Kitchen Cleaning Foam | 200–1,000 cPs; 3–8% surfactant | 150 mesh | 0.6–0.8 ml foam | 28/410 | Smooth (utility aesthetic) | WP-1393 |
| Antibacterial Hand Foam | 200–1,000 cPs; low-alcohol or surfactant base | 200 mesh | 0.5–0.6 ml foam | 28/410 | Smooth, UV | WP-1393 |
Baby care applications deserve a specific note: foam pumps are increasingly preferred for baby wash because the pre-formed foam eliminates rubbing friction on sensitive skin. However, baby formulas are typically very diluted (2–4% surfactant) and preservative-sensitive — which means the PP-only construction (no stainless steel) and 200-mesh nylon screen must be specified explicitly. SUNSHINE’s all-PP foam pump (WP-1391, WP-1393) meets this requirement without custom tooling.
Quality Testing: Foam Consistency, Mesh Life and Leak Standards
Foam pumps require a quality testing protocol that goes beyond standard pump tests — because foam quality itself (density, bubble size, collapse time) is a performance output that must be validated independently from the mechanical pump function. The following test sequence covers all failure modes SUNSHINE tests against in production.
| Test | Method | Protocol | Pass Threshold | Failure Addressed |
|---|---|---|---|---|
| Foam consistency (actuation 1 vs 500) | Photograph foam at strokes 1, 50, 200, 500; measure bubble size + volume | Fill with reference formula; actuate at 60 strokes/min; sample at intervals | Bubble size variance <20%; foam volume variance <10% | Mesh degradation; air chamber fatigue |
| Non-Spill inverted leak | ASTM D3078 variant | Fill 80% capacity; invert 60 min; weigh | <0.005 g liquid loss | Seal failure; valve suck-back |
| Formula clog test | Fill with target formula; leave 30 days at 40°C; actuate 20 strokes; assess output | Accelerated aging at ICH Q1A conditions | Foam volume >80% of baseline at stroke 1 after storage | Surfactant precipitation in mesh; formula-screen interaction |
| Actuations to clog (stress test) | Fill with 2× concentration formula; actuate until clog or 5,000 strokes | Worst-case fill scenario; documents concentration tolerance margin | >500 strokes before any clog | Overfill concentration resilience |
| Mesh life cycle | Automated actuation rig; photograph mesh at 0, 2,000, 5,000, 10,000 strokes under magnification | Measure pore enlargement at each interval | <5% pore size increase at 10,000 strokes | Long-term foam coarsening; mesh fatigue fracture |
| Drop test | ISTA 1A; 1.2 m, 6 orientations | Filled bottle + pump; weigh before and after each drop | No liquid loss; foam output unchanged at next actuation | Pump displacement; dip tube dislodge |
Sourcing from SUNSHINE: MOQ, Lead Times and Sample Policy
| Order Type | MOQ | Lead Time | Deposit | Balance | Notes |
|---|---|---|---|---|---|
| Sample (standard SKU) | 50–100 pcs | 7–10 days | 100% upfront | — | Include your formula for compatibility test; SUNSHINE tests 20 sample actuations before shipping |
| Stock SKU, standard color + smooth/ribbed | 10,000 pcs | 20 days EXW | 30% T/T | 70% before shipment | WP-1391 (24/410–28/412), WP-1393 (28/410); 200-mesh; 0.12 ml/stroke |
| Stock SKU, custom color + Aluminum/UV | 10,000 pcs | 25–28 days | 30% T/T | 70% before shipment | Finish surcharge applies; no tooling fee |
| Stock SKU, Bamboo collar | 20,000 pcs | 30–40 days | 30% T/T | 70% before shipment | Bamboo seasonally sensitive |
| Custom mesh count (100/150/300) | 20,000 pcs | +7 days | 30% T/T + screen fee | 70% before shipment | Screen swap: $100–200 one-time |
| Custom liquid dose | 20,000 pcs | +15 days | 30% T/T + tooling | 70% before shipment | Liquid chamber retool: $200–400 |
Monthly production capacity across both foam pump SKUs is 300,000 units. SUNSHINE’s foam pump lead time — 20 days EXW Ningbo — is among the fastest in the category because both foam pump sizes (24/410 and 28/410) share the same two-chamber tooling platform; only the thread collar changes between sizes. For orders above 150,000 units, advance scheduling of 8 weeks is required. Payment: 30% T/T deposit on order confirmation; 70% before shipment. L/C at sight accepted for orders above USD 50,000.
Common Foam Pump Problems and How to Prevent Them
Problem: Pump outputs liquid instead of foam on first strokes
Cause: Air chamber not yet primed; normal on first 2–5 strokes on a new bottle. Not a defect.
Prevention: Brief this to your fill line QC team — the first 5 strokes are a priming sequence, not a pass/fail trigger.
Problem: Foam becomes watery after 30–50 strokes
Cause: Formula viscosity too high (above 1,500 cPs) causing mesh screen partial clog; residue reduces air passage.
Prevention: Test formula at 1.5× target viscosity before production. If clog occurs at any viscosity within spec, switch to 150-mesh screen and increase air-to-liquid ratio.
Problem: Pump leaks during shipping
Cause: Air chamber valve not fully sealed; or overfill (above 85% bottle capacity) causing pressure spike during airfreight altitude change.
Prevention: Specify Non-Spill standard (tested per batch by SUNSHINE); limit fill to 80–85% bottle capacity.
Problem: Foam pump head won’t press down smoothly
Cause: Actuator cap binding against collar — usually a tolerance mismatch between collar outer diameter and bottle neck thread engagement.
Prevention: Send SUNSHINE a dimensional drawing of your bottle neck before ordering. Run a torque test on 5 samples with your actual bottle before approving production.
Problem: Foam is too stiff or won’t rinse
Cause: Air-to-liquid ratio too high (above 8:1) for the formula; or 300-mesh screen with a formula that rinses slowly.
Prevention: Specify foam collapse time as a parameter (target 20–30 sec for hand soap); test with 3 panelists before tooling approval.
Frequently Asked Questions
Can I use my existing hand wash formula in a foam pump without reformulating?
Almost certainly no. Most retail hand wash concentrates are 15–25% active surfactant, which is 3–5× too concentrated for a foam pump. The foam pump will produce foam for the first 10–20 strokes, then the mesh screen will clog with precipitated surfactant. You need to either dilute your existing formula to 3–8% active before filling (which changes your fill line setup) or reformulate specifically for foam pump delivery.
What is the difference between a foam pump and a foaming soap dispenser?
They are the same device — different terminology used in different markets. “Foam pump” is common in B2B/packaging industry language; “foaming soap dispenser” is more common in retail and consumer product descriptions. Both refer to a two-chamber pump with a mesh screen that converts liquid soap into foam at the point of dispensing.
Can a foam pump work with alcohol-based hand sanitizer?
Yes, if the sanitizer is gel-based at low viscosity (200–800 cPs) and alcohol content is below 70%. SUNSHINE’s PP-construction foam pump is alcohol-compatible at up to 70% ethanol. Above 70% alcohol, the liquid chamber seal (LDPE or PP) may degrade over time — request a material suitability test at 40°C for 90 days before committing to production. Gel sanitizers above 2,000 cPs will not foam correctly regardless of alcohol content.
How many doses does a 300 ml foam pump bottle deliver?
At 0.12 ml liquid per stroke, a 300 ml bottle (filled to 85% = 255 ml) delivers approximately 2,125 strokes. With typical family hand soap usage of 3 strokes per wash and 10 washes per day, the bottle lasts approximately 70 days — about 2 months of family use. This is the strongest economic argument for foam pump: a comparable 300 ml lotion pump bottle at 1.0 ml per stroke delivers only 255 doses — roughly 8–10 days of the same usage. The foam pump delivers 8× more washes from the same bottle volume.
What is the minimum order for a custom-color foam pump?
10,000 pcs — same as the standard color. PMS color matching uses masterbatch addition to the PP resin with no tooling charge. Color samples are available in 20–50 pcs within 7 days on request.
