Plastic cap, 24/410, smooth white with reducer

Plastic cap 24/410 with reducer

The plastic cap with reducer is a simple screw-on closure that seals a bottle or vial securely while the built-in reducer channels the contents into a thin stream or drop-by-drop flow. It is ideal wherever you need to dispense liquid contents precisely and cleanly — without pouring too much at once and without drips running down the neck.

Made from polypropylene (PP), which is lightweight, shatter-resistant, and handles everyday use well. The smooth body is comfortable to grip and easy to turn.

Key features

• Reducer insert – the narrowed opening slows the flow and allows dispensing the contents drop by drop or in a thin stream, which is especially appreciated with oils and concentrated liquids.
• 24/410 thread – a standard neck size; the cap fits any bottle with the same thread type as stated in the product specifications.
• PP material – resistant to most water-based and cosmetic contents, lightweight, and shatter-resistant.
• Smooth surface – easy to turn and a clean look without ribbing.

Suitable for products such as

The reducer cap is primarily suited for liquid contents dispensed in small amounts — vegetable and cosmetic oils, facial serums, tinctures, tonics, and liquid concentrates. The reducer is helpful for products where a fully open neck would release too much at once. It is not suitable for thick creams, gels, or contents with particles, as the narrowed opening would clog.

The packaging material is suitable for contact with cosmetic products and complies with the relevant regulatory requirements.

Good to know

Before first filling, wash and disinfect both the cap and the reducer (for example with isopropyl alcohol or ethanol) and allow to dry thoroughly. When reusing, make sure no residue from the previous contents remains in the reducer.

Polypropylene handles water-based and common cosmetic formulations well. With undiluted essential oils and solvents, we recommend verifying compatibility — prolonged contact with concentrated essential oils may gradually affect the material.

PP is recyclable; once the contents are used up, dispose of the cap through plastic waste collection.
