White Plastic Cap for Detergent Bottle, type 2

Plastic cap for fabric softener bottle, white, type 2

A screw cap that reliably seals bottles with a LD 42/3 neck, as used for fabric softeners, liquid detergents and other household products in larger volumes. Its purpose is to prevent spills and evaporation of the contents while allowing repeated opening during daily dispensing. It is suitable for home and small-batch production of fabric softeners, liquid detergents, dishwashing gels and all-purpose cleaners, as well as for cosmetics filled into large bottles, such as shower gels, shampoos or body lotions in family-size packaging.

The cap is made from polypropylene (PP) in cosmetic grade. The packaging material is suitable for use with cosmetic products and meets the relevant legislative requirements. The white finish matches both white and coloured bottles on which it is commonly used.

Why choose this cap

• Polypropylene – a material that resists surfactants, mild acids and bases well, which are the components of common laundry and cleaning products.
• Screw thread LD 42/3 – the standard neck type for fabric softener bottles, making the cap easy to combine with bottles of the same neck from Handymade's range.
• Repeated opening – the screw thread is designed for daily opening and closing, which is important for household products dispensed every day.
• Easy to clean – the smooth plastic washes well and requires no special maintenance.

Practical use

The cap is screwed onto the bottle neck and tightened by hand. With liquid detergents and fabric softeners, it is important that the thread is not contaminated with product residue before closing. Wipe off any drops on the neck, otherwise the cap will become harder to unscrew over time and surfactants on the thread may form a sticky film.

Before the first filling, we recommend washing the cap, disinfecting it with isopropyl alcohol or ethanol and allowing it to dry completely. This applies especially to cosmetic products, where residual moisture or impurities can reduce the microbiological stability of the contents.

Ready-made bottle + cap combinations as well as individual bottles with the same neck type are available in Handymade's range.

Suitable for products such as

• Fabric softeners and liquid detergents – the primary application; the cap is designed specifically for this type of bottle and contents.
• Dishwashing gels, all-purpose cleaners and concentrates – aqueous surfactant solutions that polypropylene tolerates well over long-term contact.
• Cosmetics in large packaging – shower gels, shampoos, body lotions or massage oils filled into bottles with the same neck.
• Working stock bottles in production – sealing intermediates and bases before further processing or transfer into smaller containers.

Good to know

Polypropylene is chemically resistant, but with highly concentrated essential oils, solvents or products with a high alcohol content, we recommend a simple test before serial filling. Leave the cap in contact with the contents for a few days and observe whether it changes shape, colour or thread flexibility. With standard aqueous detergents and cosmetic emulsions, such changes are not expected.

If the product is filled hot, let it cool to room temperature in the bottle before sealing. Otherwise, the vacuum that forms as it cools may deform the bottle and make it difficult to open.

The cap is suitable for reuse after washing. Polypropylene is among the commonly recyclable plastics.
