Product description
Plastic cap 24/410, matte black
Plastic screw cap with a 24/410 thread is designed to close bottles and vials with the same neck finish. It is a simple closure that keeps the contents securely sealed and allows repeated opening and closing — suitable wherever the product is dispensed by unscrewing and pouring, or where the bottle is intended purely for storage.
The cap is made of polypropylene (PP) in a matte black finish. The matte surface has a calm, understated appearance with no noticeable reflections, making it a good fit for product lines with a simple, muted look. PP is sturdy, lightweight, and resistant to common cosmetic ingredients, making the closure suitable for long-term, repeated use.
Where the cap is suitable
The 24/410 thread closure is among the most widely used standardised neck finishes; it fits bottles and vials for serums, oils, tonics, tinctures, and liquid products of varying viscosity. The cap itself does not dispense — contents are poured or scooped out after unscrewing — so it is best suited to applications where a pump or spray is not needed, but a reliable, leak-proof seal is.
- Storage and transport – the firm screw closure keeps the bottle securely sealed during handling and transport.
- Repeated use – the cap withstands repeated opening and closing, suitable for products consumed gradually.
- Understated look – matte black fits into simple, refined product lines with no glossy elements.
Selecting by neck finish
The cap fits bottles and vials with the same 24/410 neck finish. Ready-made combinations of bottle and cap, as well as other closures with this neck finish, are available in the Handymade range. When combining packaging and closure yourself, we recommend testing the seal and compatibility with the specific formulation — particularly with alcohol-based and oil-based contents.
Material and contact with cosmetics
The cap material is suitable for contact with cosmetic products and meets the applicable regulatory requirements. Polypropylene is resistant to most aqueous, emulsion-based, and oil-based cosmetic contents.
For contents with a higher proportion of essential oils, fragrance compositions, or solvents, we recommend verifying the seal integrity and material resistance on the finished formulation — concentrated aromatic components can affect both the plastic and any sealing insert over time.
Good to know
Before first use, wash the cap and allow it to dry thoroughly; if you are filling a product that requires higher purity, optionally wipe the surface with isopropyl alcohol or ethanol and allow to air out. When reusing, wash and dry the cap after emptying the bottle so no residue remains in the thread.
Tighten the closure firmly but without force — over-tightening can deform the thread and compromise the seal. Polypropylene is a recyclable material (PP).
Frequently asked questions
What bottles does the 24/410 cap fit?
The cap fits all bottles and vials with a 24/410 neck finish. This is a standardised thread, so the closure is interchangeable across bottles with the same neck designation. The neck type is listed in the parameters of each packaging item — use it to select the matching closure.
Is the plastic cap suitable for cosmetics?
Yes. The cap material is suitable for direct contact with cosmetic products and meets the applicable regulatory requirements. Polypropylene is resistant to common aqueous, emulsion-based, and oil-based cosmetic contents, making it suitable for long-term product closure.
Does the cap dispense the contents, or does it only seal the bottle?
The cap does not dispense the contents; it only seals the bottle. The contents are poured or scooped out after unscrewing. If you need drop-by-drop or spray dispensing, look for a dropper, pump, or spray with the same neck finish.
Is the polypropylene cap resistant to essential oils?
Polypropylene is resistant to most cosmetic contents, but at high concentrations of essential oils, fragrance compositions, and solvents it is advisable to verify resistance on the finished product. Concentrated aromatic and solvent components can affect both the plastic and the seal over time.
Can the cap be reused?
Yes. The cap withstands repeated opening and closing. After emptying the bottle, wash it and allow it to dry; before refilling, wipe the surface with isopropyl alcohol or ethanol if needed. Tighten the closure firmly but without force to avoid deforming the thread.
