Common Name(s): Polyglyceryl-10 tristearate,polyglyceryl-10 tristearate,cosmetic functional ingredient,established active
CAS Number: N/a
DESCRIPTION
What It Does: Provides emulsification, skin conditioning, or solubilisation from the polyglyceryl head group's multiple hydroxyl groups and the fatty acid ester chains.
Why It's Used: Polyglyceryl-10 tristearate is selected for its natural-origin polyglyceryl-10 head group esterified to c18 stearate โ the 10-unit glycerol backbone provides lower-hlb thickening and w/o-compatible emulsification (polyglyceryl-10 level), meeting clean-label criteria with ecocert-approvable biodegradable chemistry.
How It Works: Polyglyceryl backbone (3-10 glycerol units) provides multiple oh groups for water interaction; fatty acid ester chains provide lipophilic character. hlb determined by glycerol count ร ester chain balance.
