Common Name(s): Polyglyceryl-2 dipolyhydroxystearate,polyglyceryl-2 dipolyhydroxystearate,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-2 dipolyhydroxystearate is selected for its natural-origin polyglyceryl-2 head group esterified to c18 stearate โ€” the 2-unit glycerol backbone provides lower-hlb thickening and w/o-compatible emulsification (polyglyceryl-2 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.
