PEG-30 HYDROGENATED CASTOR OIL LAURATE.

Valuable / SKIN CONDITIONING

PEG-30 Hydrogenated Castor Oil Laurate is a versatile cosmetic ingredient primarily functioning as a surfactant, emulsifier, and solubilizer. It is integral to creating stable, smooth product textures by effectively blending oil and water components. Beyond its formulation benefits, it also offers skin conditioning properties.

Emulsifying Surfactant Solubilizer Skin Conditioning

Science

Mechanism of Action

This ingredient operates by reducing the surface tension between immiscible oil and water phases, thereby acting as an emulsifier to stabilize formulations. As a solubilizer, it aids in dispersing typically insoluble components like fragrance oils and active ingredients within a solvent system. Its surfactant capabilities also enable it to assist in cleansing by lifting oil and dirt from the skin, and it functions as a hydrophilic penetration enhancer to potentially improve ingredient delivery. Furthermore, it helps maintain skin health as a conditioning agent and enhances product spreadability.

Stability

A 5% aqueous solution of PEG-30 Castor Oil, a related compound, exhibits a pH range of 6.0-7.5. For optimal stability, it is recommended to store the ingredient light-protected in a cool and dry place. Generally, with increasing molar mass, water solubility and hygroscopicity of PEG derivatives tend to increase.

Safety Profile

CIR Status
Safe as used
Max tested
100%
Sensitization risk Low

The CIR Expert Panel deemed PEG-30 and -40 Hydrogenated Castor Oil safe for use in cosmetics at concentrations up to 100%, extrapolating these results to related PEG Castor Oils. It is considered safe when formulated to be non-irritating. However, PEG compounds can carry contamination risks, specifically ethylene oxide and 1,4-dioxane, if not thoroughly purified during manufacturing. While generally not associated with direct irritation or sensitization, PEG-35 Castor Oil (a related ingredient) has been observed in some studies to potentially enhance the sensitization of other ingredients.
