METHYL OLEATE.

Valuable CAS 112-62-9 / PERFUMING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

Methyl Oleate is a versatile fatty acid methyl ester primarily recognized for its emollient and skin-conditioning properties. It effectively smooths and softens skin by forming a protective barrier, thereby reducing moisture loss and boosting hydration. Beyond its conditioning role, it also functions as a solvent and surfactant, aiding in skin cleansing.

Emollient Skin-conditioning agent Solvent Surfactant

Science

Mechanism of Action

Methyl Oleate acts as an emollient by establishing a thin, protective layer on the skin's surface, which significantly minimizes transepidermal water loss and enhances the skin's natural moisture retention capabilities. This action leads to a perceptibly softer and smoother skin texture. Furthermore, its solvent and surfactant characteristics enable it to facilitate the dissolution of oil-soluble substances and aid in effective skin cleansing.

Stability

This ingredient exhibits sensitivity to both light and air, necessitating storage in a cool, dark environment (specifically below 15°C) and ideally under an inert gas to preserve its integrity. Its inherent C=C double bond makes it susceptible to ozonolysis, which can lead to rapid degradation and material loss if exposed to these conditions.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed Methyl Oleate's safety for cosmetic applications, provided formulations ensure it is non-irritating and non-sensitizing. As a fatty acid methyl ester, it falls within a category broadly validated for cosmetic use, aligning with regulatory standards from bodies like the EPA. Its safety profile is further supported by its exemption from tolerance requirements in pesticide formulations (as a surfactant) and its listing as an indirect food additive.
