Science
Mechanism of Action
As a non-occlusive emollient, Oleyl Lactate functions by forming a lightweight, moisture-trapping layer on the skin's surface. This action helps to reduce transepidermal water loss, contributing to enhanced hydration and improved skin elasticity. Its unique texture-modifying properties also allow it to refine product feel, reducing overall greasiness and facilitating smooth, even application.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deems Oleyl Lactate safe for use in consumer products at concentrations up to 10%, provided the final formulation pH is maintained at or above 3.5. Formulations must be designed to avoid increasing sun sensitivity, or include directions for daily sun protection. For professional salon products, concentrations up to 30% are permitted under specific conditions (pH ≥3.0, brief use, thorough rinsing, professional application, sun protection). It holds an FDA UNII number and is rated with 'LOW' concerns for cancer, allergies, immunotoxicity, and developmental/reproductive toxicity by the EWG Skin Deep database. It presents low irritancy and comedogenicity risks.
