In cosmetic packaging, droppers are common accessories made from various materials, with PP (polypropylene), Bakelite, and ABS (acrylonitrile-butadiene-styrene) being frequently used.

PP (Polypropylene) is a lightweight, chemically-resistant thermoplastic that offers excellent thermal stability and rigidity. It has good transparency, allowing for attractive coloration options, which is essential for cosmetic presentation. Its strong resistance to moisture and oily substances makes PP suitable for a wide range of cosmetic products, particularly liquid and semi-liquid formulations.

Bakelite, a type of phenolic resin, is one of the earliest synthetic plastics and is renowned for its exceptional heat resistance and electrical insulation properties. In cosmetic packaging, Bakelite is often used in the upper part of the dropper or the valve due to its hardness and rigidity, contributing to the durability of the product. Its ability to withstand high temperatures makes it ideal for items that may undergo heating processes.

ABS (Acrylonitrile-Butadiene-Styrene) is a versatile thermoplastic known for its toughness and strength. It boasts high impact resistance and excellent processability, allowing droppers to be designed into various intricate shapes. The smooth surface of ABS enhances the user experience, and its chemical resistance makes it suitable for a wide array of cosmetic formulations.

In summary, PP, Bakelite, and ABS each possess unique characteristics that cater to different aspects of cosmetic packaging. Choosing the right material depends on product specifications, design preferences, and usability requirements.
