Cellulose Acetate Butyrate is a synthetic polymer derived from cellulose, a natural plant fiber. It functions primarily as a film-forming agent in cosmetic products, creating a thin, flexible layer on the skin or hair. This film can help to hold ingredients in place, provide water resistance, or improve product longevity.
