INCI: polyester-7 (and) neopentyl glycol diheptanoate
LexFilm Sun is a patented water-proofing agent and solubilizer for UV actives. It is a synergistic combination of a high molecular weight, water-resistant polymer with a light dry emollient. The combination yields a fluid with superior solubility for organic UV filters. LexFilm Sun is a pourable fluid. It is the only oil phase excipient needed. LexFilm Sun contributes less formulation costs than other combinations of solubilizers and water-proofers. This material has both good dielectric properties and superior solubilization attributes. LexFilm Sun can also improve transfer resistance in color cosmetics such as lipsticks, mascara, and foundations.
