Science
Mechanism of Action
Based on research regarding Sodium Stearoyl Lactylate, this ingredient functions primarily as an anionic emulsifier, adeptly blending oil and water components to create stable, homogeneous formulations with improved sensory characteristics. It also contributes as a humectant, forming a mild barrier to support skin hydration. Furthermore, it conditions the skin, promoting a soft, smooth, and supple feel, and may aid in the enhanced absorption of other active ingredients. In cleansing products, Sodium Stearoyl Lactylate can act as a gentle cleansing agent and a foam booster.

Stability
Sodium Stearoyl Lactylate exhibits poor heat resistance and is susceptible to hydrolysis in acidic, alkaline, or enzymatic environments. Its stability, particularly the alpha-gel phase when co-formulated with glycerol monostearate, can be altered by changes in environmental pH.
Safety
Safety Profile
The CIR Expert Panel concluded that Sodium Stearoyl Lactylate is safe for cosmetic use, provided it is formulated to be non-irritating and non-sensitizing. Maximum reported use concentrations for Sodium Stearoyl Lactylate include up to 10% in rinse-off skin cleansing products, up to 7% in leave-on hair grooming aids, and up to 1.9% in leave-on moisturizing skin care preparations. It is also FDA-approved for both food and cosmetic applications. This safety assessment specifically pertains to Sodium Stearoyl Lactylate.

Verdict
While the closely related Sodium Stearoyl Lactylate demonstrates valuable multi-functional properties and a favorable safety profile (low irritancy and comedogenicity, CIR-approved), direct clinical and safety data for Stearyl Lactate itself are not available within the provided research, rendering its precise utility for Moumoujus unconfirmed.
