VP/HEXADECENE COPOLYMER is an oil – soluble polymer formed by the copolymerization of vinylpyrrolidone and hexadecene monomers, with a CAS number 32440-50-9. VP/HEXADECENE COPOLYMER is mainly used as an ingredient in cosmetics and personal care products, presenting as a pale yellow to yellow viscous liquid and being insoluble in water.

1. Sunscreen Products
This is one of its core application scenarios. As a water-resistant film-forming agent, VP/hexadecene copolymer can form a continuous, hydrophobic film on the skin surface after application of sunscreen. This film locks in sunscreen active ingredients (such as zinc oxide, titanium dioxide, or organic UV absorbers), preventing them from being washed away by sweat or water during swimming, sports, or daily outdoor activities. It extends the effective protection time of sunscreens and improves the durability of SPF and PA values. For example, VP/HEXADECENE COPOLYMER is commonly added to high-end water-resistant sunscreens and outdoor sports sun protection sprays to enhance product reliability.
2. Color Cosmetics
(1) Face Makeup
Concealers and Tinted Moisturizers: As a binder and adhesion enhancer, VP/HEXADECENE COPOLYMER helps the product adhere tightly to the skin, covering blemishes, dark circles, and redness for a long time without creasing or fading due to skin oil secretion or external friction. Luminous tinted moisturizers also rely on it to balance coverage and skin-friendliness, creating a natural, dewy finish.
Powder Foundations and Blushes: VP/HEXADECENE COPOLYMER acts as a pigment dispersant and anti-caking agent, making color pigments evenly distributed in the powder matrix to avoid color spots or agglomeration. For liquid blushes, it improves the product’s spreadability and blending performance, ensuring the color adheres to the cheeks naturally and lasts for hours.
(2) Eye and Lip Makeup
Mascaras and Eyeliners: VP/HEXADECENE COPOLYMER can disperse carbon black or color pigments evenly, preventing the mascara from clumping into “spider legs” and enhancing the adhesion of eyeliner to the lash line, avoiding smudging caused by eye moisture or sebum.
Lip Glosses and Lipsticks: As a film-forming and moisturizing auxiliary, it forms a thin, flexible film on the lips, locking in the color of lip products and reducing the frequency of touch-ups due to eating or drinking. It also improves the smoothness of lip gloss, avoiding a sticky or dry feel.
3. Antiperspirant and Deodorant Products
In antiperspirants (including roll-ons, sprays, and sticks), VP/hexadecene copolymer serves as an emulsion stabilizer and active ingredient fixative. It helps disperse and fix antiperspirant active ingredients (such as aluminum zirconium tetrachlorohydrex glycine) on the underarm skin, enhancing the antiperspirant effect by slowing down the secretion of sweat glands. At the same time, VP/HEXADECENE COPOLYMER improves the stability of the product system, preventing the separation of oil and water phases during storage and ensuring consistent product performance.
4. Hair Care Products
Though less commonly used than in facial cosmetics, it is added to some high-end styling products (such as hair waxes and styling creams) as a film-forming and conditioning agent. VP/HEXADECENE COPOLYMER forms a lightweight film on the hair surface, helping to shape and maintain hairstyles without making the hair stiff or frizzy. It also reduces moisture loss from the hair cuticle, improving the hair’s smoothness and luster.
5. Specialized Personal Care Products
For sensitive skin care products and men’s grooming products (such as aftershave balms with color correction), VP/HEXADECENE COPOLYMER is valued for its low-irritation and compatibility. VP/HEXADECENE COPOLYMER can improve the product’s skin-friendliness while maintaining functional properties, meeting the needs of specific consumer groups for mildness and effectiveness.
1. Excellent film – forming and waterproof ability: It can form a soft, dense and continuous flexible film on the surface of skin, hair and nails. This film not only has a moisture – locking effect to reduce the loss of skin and hair moisture, but also has hydrophobicity. VP/HEXADECENE COPOLYMER can effectively prevent the product ingredients from being washed away by sweat or water, thus endowing sunscreen and makeup products with excellent water resistance and durability.
2. Strong ingredient binding and viscosity regulation: As a binder, it can firmly bond various components in cosmetics together to avoid component separation, especially for powdery pressed products such as pressed blushes and powder cakes. At the same time, it can adjust the viscosity of the product, increase the thickness of the product solution, avoid the product being too thin and flowing randomly, and make it easier to apply and spread during use.
3. Efficient pigment dispersion and emulsion stabilization: VP/HEXADECENE COPOLYMER has good pigment dispersion performance, which can make the color pigments in mascara, eye shadow, lipstick and other color cosmetics evenly distributed, avoiding pigment agglomeration and color spots. In antiperspirant products, it can also act as an emulsion stabilizer to prevent the oil – water phase separation of the product during storage and improve the stability of the product system, thus enhancing the effectiveness of antiperspirant ingredients.
4. Gentle shaping and gloss enhancement: When used in hair styling products, VP/HEXADECENE COPOLYMER can form a light film on the hair surface to help shape and maintain the hairstyle. Unlike some rigid styling ingredients, it will not make the hair stiff, and can keep the hair soft and natural. In addition, VP/HEXADECENE COPOLYMER can also bring a glossy finish to lip gloss, liquid foundation and other products, improving the appearance texture of the products.
