Glass bottles are mostly used in skin care products (creams, lotions), perfumes, essential oils, and nail polishes. They are small in size and rarely used in cosmetics.
Essential oil bottles are usually made of amber or colored sand to protect them from light. The cap has a tamper-proof ring and can be equipped with an inner plug or dropper.
Glass bottles are divided into wide-mouth bottles and narrow-mouth bottles.
Solid pastes are generally used in large-mouth bottles, and are suitable for aluminum or plastic bottle caps.
Emulsion or water paste is generally used in narrow-mouth bottles and is suitable for use with the pump head. Care should be taken to prevent the spring and ball from rusting.
Most pump heads are equipped with glass beads, which are usually used for material testing. The cover should match the internal plug, the water agent should match the small hole and the internal plug, and the thick emulsion will match the large hole plug.

The easiest and most thorough way to disinfect plastic bottles and packaging materials is to wash them with water and then bake them at high temperature for disinfection.
