SODIUM STEAROYL HYALURONATE.

Insufficient Data CAS 222400-51-3 / HAIR CONDITIONING, SKIN CONDITIONING

Sodium Stearoyl Hyaluronate is an innovative derivative of hyaluronic acid, chemically modified with a stearoyl fatty acid component. This unique structure allows it to deliver both the renowned humectant benefits of HA and enhanced emollient properties to the skin, acting as a dual-action ingredient for significant hydration and barrier support.

Humectant Emollient Skin Conditioning Hair Conditioning Barrier Support Hydration

Science

Mechanism of Action

This ingredient functions by leveraging the dual nature of its structure. The hyaluronic acid component acts as a powerful humectant, drawing and binding moisture within the skin, thereby enhancing hydration, reducing transepidermal water loss, and contributing to a plumper appearance. Simultaneously, the stearoyl group is inferred to provide emollient effects, strengthening the skin's lipid barrier and offering superior conditioning, thus optimizing skin barrier function and overall skin health.

Stability

Specific stability data for Sodium Stearoyl Hyaluronate is not detailed; however, its parent compound, Sodium Hyaluronate, is known to degrade when exposed to high temperatures, light, and oxidative stress. To maintain ingredient integrity, formulations should incorporate appropriate antioxidants and be stored in conditions that minimize light and heat exposure.

While the Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of related hyaluronic acid forms (Hyaluronic Acid, Potassium Hyaluronate, Sodium Hyaluronate) for cosmetic applications, a specific CIR, SCCS, or FDA safety assessment for Sodium Stearoyl Hyaluronate itself is currently unavailable. It is recognized in the EU CosIng database primarily as a hair and skin conditioning agent, and incidodecoder.com indicates low irritancy.
