HYDROGENATED STYRENE/BUTADIENE COPOLYMER

Last update on May 31, 2024

Hydrogenated Styrene/Butadiene Copolymer is a synthetic polymer commonly used in cosmetics and personal care products for its film-forming properties. It appears as a colorless to light yellow solid or semi-solid, providing a flexible, durable layer that enhances the texture and wear of formulations like foundations, lipsticks, and mascaras. This copolymer improves the product's water resistance and longevity on the skin. The chemical formula of Hydrogenated Styrene/Butadiene Copolymer is (C₈H₈.C₄H₆)_x. It is well-tolerated and safe for topical use.

What is HYDROGENATED STYRENE/BUTADIENE COPOLYMER used for?

Hydrogenated Styrene/Butadiene Copolymer is used in skin and hair care products for its exceptional properties.

Skin care: In skin care, Hydrogenated Styrene Butadiene Copolymer provides a flexible, durable layer that enhances the texture and longevity of products like foundations, sunscreens, and lotions. This polymer helps improve water resistance, ensuring longer-lasting wear and protection
Hair care: For hair care, Hydrogenated Styrene Butadiene Copolymer is often found in styling products such as gels, mousses, and sprays, where it offers hold, flexibility, and humidity resistance. Its ability to form a lightweight, non-greasy film makes it ideal for creating smooth, manageable hairstyles while protecting hair from environmental stressors

Origin

Hydrogenated Styrene/Butadiene Copolymer is made by polymerizing styrene and butadiene monomers to form styrene/butadiene copolymer. This copolymer undergoes hydrogenation, a chemical process where hydrogen is added to reduce double bonds, saturating the polymer. The hydrogenation enhances the stability and compatibility of the copolymer with other ingredients. The final product is purified to remove any residual monomers or byproducts

Safety Profile

Hydrogenated Styrene/Butadiene Copolymer is generally considered non-toxic and safe for use in cosmetics and personal care products. The Cosmetic Ingredient Review (CIR) Expert Panel has assessed its safety and found it to be non-irritating and non-sensitizing when used as intended. It does not penetrate the skin significantly, reducing the risk of systemic exposure. However, a patch test must still be performed prior to full application.
