PEG-30 HYDROGENATED CASTOR OIL ISOSTEARATE.

Valuable / SURFACTANT - EMULSIFYING, VISCOSITY CONTROLLING

PEG-30 Hydrogenated Castor Oil Isostearate is a highly versatile non-ionic surfactant and emulsifier, critical for creating stable emulsions by blending oil and water phases. It also functions as an effective solubilizer, integrating challenging-to-dissolve components, such as fragrances, into aqueous solutions.

Science

Mechanism of Action

This ingredient functions by reducing the surface tension between different substances, thereby facilitating the formation of stable emulsions. As an emulsifier, it ensures the homogenous blending of immiscible liquids, while its solubilizing properties allow hydrophobic compounds to disperse uniformly within aqueous solvents. Furthermore, it acts as a dispersing agent, a water-soluble lubricant, and a pigment-wetting agent, contributing to enhanced product texture and uniform ingredient distribution.

Max tested
100%
Sensitization risk Low

The CIR Expert Panel concluded that PEG-30 and PEG-40 Hydrogenated Castor Oils are safe for cosmetic use at concentrations up to 100%, extrapolating this finding to the entire family, including PEG-30 Hydrogenated Castor Oil Isostearate, when formulated to be non-irritating. While a related compound, PEG-40 hydrogenated castor oil, caused one instance of almost imperceptible erythema among 5 subjects at 0.05% in a patch test, the overall safety assessment remains strong. Polyethylene Glycols (PEGs) may contain trace amounts of 1,4-dioxane, a possible carcinogen, with acceptable concentrations typically maintained below 30ppm. This ingredient's family members are also approved by the FDA as direct and indirect food additives. No SCCS information specific to this ingredient was found.
