Common Name(s): Peg-40 glyceryl triisostearate,peg-40 glyceryl triisostearate,peg-glyceryl emulsifier,ethoxylated glyceride
CAS Number: N/a
DESCRIPTION
What It Does: Provides o/w emulsification from peg-40 ethoxylation of triisostearate glyceride, with hlb ~16 enabling stable oil-in-water formulations with the emollient character of the glyceride contributing skin feel alongside surfactant function.
Why It's Used: Peg-40 glyceryl triisostearate is selected for peg-40 ethoxylated triisostearate hlb 16 emulsification โ the peg chain length precisely tunes the hlb for o/w emulsion stability while the glyceride lipid moiety provides emollient co-contribution absent from conventional surfactant emulsifiers.
How It Works: Peg-40 chain: ether oxygen h-bonding โ water miscibility; triisostearate glyceride tail โ oil phase anchoring; hlb ~16 โ o/w interface stabilisation.
Typically Found In: Emollient formulas,o/w emulsions

Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Peg-glyceryl emulsifier eo chain length (peg-n) is the primary hlb tuning parameter โ incrementing peg-n by 5 increases hlb by approximately 1 unit.
