What It Does

PEG-150 Distearate is a high molecular weight polyethylene glycol diester created by reacting 150 moles of ethylene oxide with two molecules of stearic acid. This large PEG chain gives it exceptional thickening and stabilizing properties in surfactant systems, making it particularly valuable in shampoos and body washes where it creates pearlescent effects and builds viscosity without heavy feel. Formulators choose it specifically for its ability to enhance foam quality, provide elegant texture, and stabilize formulations containing high levels of surfactants, while its high HLB value ensures good water solubility and rinsability.

Known Interactions

DIHYDROXYACETONEUse Cautionperoxide_oxidation

Ethoxylated surfactants (Ceteareth-*, PEG-*, Polysorbate-*, Poloxamer-*) accumulate peroxides over shelf life via air oxidation of the polyoxyethylene chain. The resulting peroxides degrade DHA, accelerating off-smell and producing orange tones. For DHA formulations, prefer non-ethoxylated emulsifiers: Polyglyceryl-* esters (Polyglyceryl-6 Distearate, Polyglyceryl-10 Stearate), Lecithin, Sucrose Stearate, Olivem 1000 (Cetearyl Olivate + Sorbitan Olivate).
