## 1. Executive Summary & Core Engineering Scope
Nail polish bottle sourcing from China: why the solvent (ethyl and butyl acetate) forces glass with a PP cap and a solvent-resistant brush, common 5–15 ml sizes, cap and brush specification, QC thresholds, indicative MOQ and lead time.

Nail polish is a high-volatility solvent formula — ethyl acetate and butyl acetate carrying nitrocellulose and pigment — and that single fact decides the packaging before any shape does. The solvent swells or dissolves PET, PS, AS, PMMA and most standard gaskets and lifts ordinary inks. So the bottle is glass, the cap is PP, the brush is solvent-resistant, and the seal in the cap is the part that keeps the polish from turning to gum on shelf. Here is how to specify, test and source it.

A nail polish bottle is glass with a PP screw cap carrying a cone seal and a nylon-bristle brush on a PP stem, because the solvent system (ethyl and butyl acetate) attacks PET, PS, AS, PMMA and standard gaskets. Common sizes are 5, 10 and 15 ml on stock (public-mould) glass, from about 500 pieces undecorated and ~2,000 printed ; made-to-order glass in your own shape carries a 30,000+ piece floor and 30–60 days from mould approval.

Nail polish and nail-polish remover sit in the same compatibility class as perfume: high-volatility solvent that permeates and swells many plastics and rubbers, evaporates through a poor seal, and lifts ordinary inks. The formula × packaging compatibility matrix gives the rule directly: glass bottle plus brush cap with a cone seal in the cap and solvent-resistant bristles; for acetone remover, glass with a purpose-made inner plug and cap liner. No stock plastic bottle is acceptable for either, regardless of supplier assurance. In practice that means:

The neck vocabulary — T, E, I, S, X dimensions — and why the closure factory needs the full drawing are on the neck finish and closure standards reference; glass grades and defect allowances are on glass bottle specifications .

Nail polish glass is one of the most heavily tooled public-mould categories in China, so a stock shape rarely needs a mould. The gate is the decoration minimum, then the made-to-order glass floor if you insist on your own shape. Figures below are indicative ranges via partner factories; the cross-category view is on the MOQ index 2026 .
