COCOA BUTTER PEG-8 ESTERS.

Valuable CAS - / SKIN CONDITIONING - EMOLLIENT

COCOA BUTTER PEG-8 ESTERS is a sophisticated emollient and skin conditioning agent that enhances skin softness and smoothness. Beyond its direct skin benefits, this polyethylene glycol (PEG) derivative serves a crucial role as a solubilizer and surfactant, optimizing formulation stability and ingredient delivery by expertly blending oil and water phases.

Summary

Emollient Skin-Conditioning Agent Solubilizer Surfactant

Science

Mechanism of Action

This ingredient operates as a multi-functional agent, primarily conditioning the skin by providing emollient properties that lead to a softer, smoother epidermal texture. As a PEG-derivative, it concurrently functions as a solubilizer, facilitating the homogenous dispersion and dissolution of oil-soluble components in water-based formulations. Its surfactant activity aids in reducing surface tension, promoting the emulsification of otherwise immiscible substances within a product.

Stability

Polyethylene glycols and their derivatives are widely utilized in cosmetic products due to their broad spectrum of viscosity and solubility properties. The water solubility and hygroscopicity of polyethylene glycols typically decrease with increasing molar mass. No specific formulation incompatibilities have been identified for COCOA BUTTER PEG-8 ESTERS.

Safety

Safety Profile

CIR Status
Safe as used
Max tested
10%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEG propylene glycol esters, encompassing related PEGylated alkyl glycerides like COCOA BUTTER PEG-8 ESTERS, are safe for use in cosmetics. A key re-review in 2010 notably removed the prior caution against using PEGs on damaged skin. Specifically, these ingredients are considered safe in rinse-off products and safe at concentrations up to 10% in leave-on products, supported by comprehensive ocular and sensitization data. While general assessments of PEG-8 and PEG-8 stearate indicate low oral and dermal toxicity, and a lack of irritation or sensitization on normal skin, no distinct SCCS opinion or FDA cosmetic status has been identified for this precise ingredient.
