Science

Mechanism of Action

This ingredient functions in multiple ways within a skincare matrix. Primarily, it acts as an emulsifier, stabilizing the oil and water components essential for the integrity of lotions, creams, and serums. As a surfactant, it reduces surface tension, thereby assisting in the dispersion and removal of dirt, oil, and impurities from the skin and hair during cleansing. Its solubilizing capability allows for the uniform integration of oil-soluble ingredients, such as fragrances and active compounds, into water-based systems. Furthermore, it offers emollient benefits, supporting the skin's moisture balance by forming a protective layer, reducing moisture loss, and enhancing overall hydration and softness.

Sensitization risk Low

The CIR Expert Panel has determined PEG-7 Hydrogenated Castor Oil, along with 130 other PEGylated oils, to be safe for cosmetic use under current practices, provided the finished product is formulated to be non-irritating. This reassessment supersedes a 1997 conclusion. It can be used in concentrations up to 100% in anhydrous products, with typical use levels in emulsions and surfactant-based systems ranging from 0.5% to 10%. While potential impurities like ethylene oxide and 1,4-dioxane from the ethoxylation process are acknowledged, reputable manufacturers implement rigorous quality control measures to minimize these to safe, acceptable limits.
