PEG-15 GLYCERYL RICINOLEATE.

Valuable CAS 51142-51-9 / SURFACTANT - EMULSIFYING

PEG-15 Glyceryl Ricinoleate is a precision ester primarily utilized for its emulsifying and surfactant capabilities, crucial for the stable integration of disparate oil and water phases in cosmetic formulas. It also functions as a skin conditioning agent, contributing to enhanced skin hydration and a softened texture.

Emulsifying Surfactant Skin Conditioning Emollient Solubilizer Humectant

Science

Mechanism of Action

This ingredient functions by bridging the gap between incompatible substances, leveraging its molecular structure which contains both lipophilic (oil-attracting) and hydrophilic (water-attracting) segments. This dual affinity effectively reduces interfacial tension, enabling stable emulsions. On the skin, it provides moisturizing and softening effects, thereby acting as a conditioning agent.

Stability

Polyethylene glycols and their derivatives, including PEG-15 Glyceryl Ricinoleate, offer broad viscosity and solubility, making them suitable for diverse formulations. They exhibit good skin tolerability, are not prone to microbiological sensitivity, and are effective as nonionic emulsifiers in neutral, mildly alkaline, and acidic systems.

Conflicts

  • Formulations must be carefully designed to be non-irritating, especially when incorporating higher concentrations of this ingredient.
  • Manufacturers are advised to employ purification procedures to ensure potential impurities like ethylene oxide (maximum 1 ppm) and 1,4-dioxane (maximum 5 ppm) are removed to meet safety standards.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has concluded that PEGylated alkyl glycerides, a category encompassing PEG-15 Glyceryl Ricinoleate, are safe for use under current cosmetic practices and concentrations, provided the final formulation is non-irritating. This assessment supersedes prior limitations for certain related PEG compounds. A key consideration for all PEG-containing ingredients is the presence of potential impurities, specifically ethylene oxide and 1,4-dioxane; the cosmetic industry is advised to implement rigorous purification processes. PEG compounds are generally recognized as safe by the FDA across various applications.
