Butylphthalimide
What Butylphthalimide is & what it does
Butylphthalimide is a synthetic compound from the phthalimide family, the N-butyl derivative of phthalimide. In cosmetic formulas it is typically used as a plasticizer that helps film-forming ingredients spread evenly and stay flexible, which is useful in products such as nail polish and certain leave-on coatings. It is an oil-soluble, fully synthetic material rather than a plant extract.
