PEG-150 Distearate

• PEG-150 distearate is a macromolecule nonionic surfactant that was developed in recent years, it has good thickening efficiency for shampoo and bath lotions, while it has some conditioning effects in hair products.

• PEG-150 distearate has an HLB value of about 18, also be used as a nonionic emulsifier for o/w systems

√ increase the hydrodynamic size and viscous drag of micelles in solution by extension of hydrated PEG chains into the aqueous phase

√ increase the micellar radius of curvature to promote wormlike micelle formation—due to incorporation of the bulky C18 stearate hydrophobes into the micellar core and shielding of electrostatic head group repulsions between ionic surfactants by the nonionic PEG chains

√ physically crosslink micelles via intermicellar bridging
