What is Trihydroxystearin?
Trihydroxystearin (CAS 139-44-6), also known as Glyceryl tri(12-hydroxystearate), is a fully esterified glycerol derivative of 12-hydroxystearic acid. Also marketed as CUTINA BW.
Where is Trihydroxystearin used?
- Personal care and cosmetics: body and texture in lipsticks, balms and anhydrous creams without greasiness
- Industrial lubricants: gelling agent in grease systems, building a stable thixotropic network that holds base oils under mechanical stress
- Coatings and adhesives: flow and sag control in high-viscosity formulations on vertical surfaces
- Food: release agent and emulsifier in confectionery and bakery
- It acts as a rheology modifier, emulsifier and lubricant.
Good to know: Food-grade material conforms to FCC requirements; technical-grade material serves industrial lubricant and coatings applications where food compliance is not required.
