PEG-18 PALM GLYCERIDES.

Valuable / SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

PEG-18 Palm Glycerides is a sophisticated polyethylene glycol derivative derived from palm oil, functioning primarily as a versatile skin-conditioning agent, emollient, and emulsifier. It enhances skin hydration and smoothness while ensuring the stability of complex formulations by effectively blending oil and water components.

Summary

Emollient Emulsifying Surfactant Skin-Conditioning

Science

Mechanism of Action

This ingredient operates through several key pathways within a formulation and on the skin. As an emollient, it contributes to skin softness and smoothness by creating a light, occlusive film on the epidermal surface. This film aids in moisture retention, shielding the skin from environmental stressors and reducing transepidermal water loss. Its surfactant and emulsifying capabilities are crucial for stabilizing oil-in-water emulsions by lowering the interfacial tension between incompatible substances. Additionally, polyethylene glycols, including PEG-18 Palm Glycerides, are recognized for their potential to enhance the topical penetration of other active compounds.

Stability

Polyethylene glycols and their derivatives, such as PEG-18 Palm Glycerides, are characterized by their broad stability across various pH conditions and are generally well-tolerated. They exhibit resistance to microbiological degradation, which can contribute to the overall stability of a product and potentially reduce the need for extensive preservation. The solubility of PEGs typically decreases proportionally with an increase in their molar mass.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEGylated alkyl glycerides, including PEG-18 Palm Glycerides, are safe for use in cosmetics when formulated to be non-irritating. This conclusion supersedes an earlier 1999 report that imposed a 10% limit on some related PEG glyceryl cocoates in leave-on products. While certain undiluted related PEG compounds demonstrated irritation in animal studies, PEG-18 Palm Glycerides itself generally showed no irritation or sensitization in human studies when properly formulated. Specific FDA cosmetic status for PEG-18 Palm Glycerides is not available, though some related PEGylated alkyl glycerides are approved for dietary supplements and indirect food additives.
