Common Name(s): Hydrolyzed lac,hydrolyzed lac,shellac hydrolysate,natural resin film former
CAS Number: N/a
DESCRIPTION
What It Does: Provides aleuritic acid and shellolic acid film-forming activity with natural antimicrobial resin character and skin conditioning from the hydrolysed polyester shellac backbone.
Why It's Used: Hydrolyzed lac is selected for aleuritic acid's unique hydroxyl fatty acid chemistry — the 9,10,16-trihydroxypalmitic acid provides a water-dispersible natural film-former with antimicrobial character from the lac resin tradition, offering clean-label alternatives to synthetic film-forming resins.
How It Works: Shellac hydrolysis: polyester resin → aleuritic acid (9,10,16-oh c16:0) + shellolic acid → water-dispersible polyhydroxy acids → film-forming skin surface conditioning.
Typically Found In: Film-forming,natural beauty
