CELLULOSE ACETATE BUTYRATE

Description

Cellulose Acetate Butyrate (CAB) is a versatile thermoplastic polymer derived from cellulose, a naturally occurring polysaccharide. This synthetic compound is created through the esterification of cellulose with acetic and butyric acids, resulting in a material with unique properties beneficial for skincare and cosmetic applications. CAB exhibits excellent film-forming capabilities, creating a smooth, flexible barrier on the skin's surface. This characteristic makes it valuable in formulations for long-wearing makeup, sunscreens, and other topical products requiring extended durability. The polymer's high refractive index contributes to optical blurring effects, potentially reducing the appearance of fine lines and imperfections. CAB demonstrates good solubility in various organic solvents, facilitating its incorporation into diverse formulation types. Its low moisture absorption properties help maintain product stability and extend shelf life. Additionally, CAB offers resistance to yellowing and degradation from UV exposure, enhancing the longevity of skincare products. The ingredient's compatibility with a wide range of cosmetic ingredients allows for versatile formulation options. While generally considered safe for topical use, formulators should be aware of potential sensitivities in some individuals and conduct appropriate testing before incorporation into final products.
