White Plastic Bottle, HDPE 40/410, White Plastic Foaming Pump, 500 ml

The HDPE plastic bottle with foam pump 500 ml is a ready-to-fill set for liquid cleaning products to be dispensed directly as a fine foam. The foam pump mixes the liquid with air without a propellant gas, and the white opaque HDPE bottle shields the contents from light. The set is designed for any situation where the customer should receive a measured dose of ready foam with a single press – from household washbasins to high-turnover commercial settings.

Key benefits

• Foam dispensing without gas – the pump creates foam mechanically by mixing the product with air, so the formulation requires no aerosol system or propellant.
• Light protection – the white opaque wall of the bottle transmits only minimal light, helping to maintain the stability of fragrance components, dyes and more sensitive active ingredients.
• Lightweight and shatterproof packaging – HDPE withstands everyday handling in the bathroom and during transport. Suitable for showers and beside washbasins, where glass would be a risk.
• Economical dispensing – foamed product is used in smaller quantities than liquid, so the bottle contents last longer.
• Suitable for cosmetics – both the bottle and pump are declared suitable for contact with cosmetic products. A declaration of conformity is available at the product.

What the set is suitable for

The foam pump works only with products of low viscosity, close to water. The set is therefore designed for water-based surfactant formulations: foam soaps for hands and body, facial cleansing foams, foam shampoos, children's wash foams, intimate wash foams or shaving foams without propellant gas. With its 500 ml volume, it is also suitable for family-size packs or for settings with fast consumption – salons, workshops, public washrooms.

The set is not suitable for thick gels, creams, oils or emulsions. The pump will not draw these in or produce foam from them, and the mechanism will clog. For such products, a set with a standard dispensing pump is more appropriate.

Filling and volume

The nominal volume is the volume the bottle is designed to hold during regular filling. The total volume to the brim is the physical capacity up to the neck and is slightly larger. The difference provides a reserve for the dip tube and pump mechanism and for any expansion of the contents with temperature change. The bottle is filled to the nominal volume, not to the brim – otherwise the contents will be pushed out through the neck when the pump is screwed on, and the set will not seal.

On first use, the pump needs to be primed empty several times until the dip tube draws in the product and the mechanism is filled. A single press dispenses approximately 1 ml of product as foam, which is a standard single-use dose for washing hands or face.

Useful to know

Preparation before filling – new packaging is recommended to be rinsed, sanitised with isopropyl alcohol or ethanol and allowed to dry completely before first use. Residual water would dilute the product and could promote microbial contamination. The pump just needs to be rinsed with clean water and left to dry with the dip tube facing downward.

Filling temperature – HDPE is not designed for hot filling. Allow the product to cool to room temperature before filling. A warm liquid may deform the bottle wall and pull it inward as it cools.

Essential oils and solvents – HDPE is resistant to common cosmetic ingredients. For formulations with a higher proportion of essential oils or alcohol, however, we recommend checking that the packaging does not deform after several weeks and that the pump still seals. For a foam pump, such formulations are marginal anyway, as a higher oil content reduces foam formation.

Reuse – the set can be reused after thorough washing and disinfection. Before the next fill, prime the pump with clean water to prevent dried surfactant residues from accumulating in the mechanism and clogging the mesh.

Labelling – the smooth cylindrical wall of the bottle is suitable for self-adhesive labels.

Recycling – the HDPE bottle and PP pump are plastic packaging. Before disposal, we recommend emptying the set and separating the components.

Closures and dispensers with the same neck type and other ready-made combinations are available in the Handymade range. For your own combination, we recommend verifying the seal and packaging behaviour with your specific formulation.
