Science

Mechanism of Action

This ingredient functions by reducing the interfacial tension between immiscible oil and water phases, thereby creating stable emulsions. As a surfactant, it also aids in cleansing the skin. Based on structurally similar lactylates, Sodium Oleoyl Lactylate is inferred to potentially support the formation of a mild moisturizing barrier and enhance the dermal absorption of other active compounds.

Stability

Lactylic esters, including Sodium Oleoyl Lactylate, typically require heat for effective dispersion in aqueous solutions and are soluble in organic solvents like vegetable oils. They are commonly employed to stabilize oil-in-water emulsions. The stability of gel phases in formulations using lactylates can be influenced by environmental pH.

CIR Status
Safe with restrictions
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Sodium Oleoyl Lactylate and related alkyl lactyl lactate salts safe for use in cosmetics, provided formulations are non-irritating and non-sensitizing. While no specific maximum concentration for Sodium Oleoyl Lactylate was established, related lactylates like Sodium Stearoyl Lactylate have been used up to 10% in rinse-off products. Sodium Stearoyl Lactylate is also FDA-approved as a direct multifunctional food additive. No specific SCCS opinion was found for Sodium Oleoyl Lactylate.
