VP/Hexadecene Copolymer is a synthetic, amphiphilic polymer made from vinylpyrrolidone (water-soluble) and hexadecene (oil-soluble) monomers.
Its primary use is in cosmetics and personal care products as a versatile performance ingredient. It acts as an excellent film-former and water-resistance agent in sunscreens, makeup (foundation, mascara), and hair sprays, providing long-lasting wear. It also works as a stabilizer and dispersant in cleansers and moisturizers, helping to blend oils and water into smooth, stable formulas. Essentially, it bridges oil and water components to improve product texture, durability, and application.

VP/Hexadecene Copolymer is a synthetic polymer made from two monomers:
VP: Vinylpyrrolidone, a water-soluble monomer.
Hexadecene: A long-chain (C16) olefin, which is oil-soluble.
This combination creates an amphiphilic copolymer—meaning it has both hydrophilic (water-loving) and hydrophobic (oil-loving) parts.
Its key property is the ability to stabilize mixtures of oil and water, making it valuable as:
A Film-Former & Water-Resistance Agent: Primarily in cosmetics and personal care (e.g., sunscreen, long-wear foundation, mascara, hair spray). It forms a flexible, water-resistant film that binds pigments, enhances longevity, and provides a smooth feel.
A Stabilizer & Dispersant: In products like makeup removers, cleansing oils, and some skincare, it helps blend oils and water into stable formulas.
An Agent in Industrial Applications: Used as a dispersant, stabilizer, or processing aid in areas like coatings, inks, and adhesives.
In short, it's a versatile ingredient that improves the performance, texture, and durability of cosmetic products by bridging oil and water components.
