Science
Mechanism of Action
This ingredient functions by significantly lowering the surface tension of liquids, which facilitates the homogeneous blending of oil and water. On the skin, it acts as a cleansing agent, efficiently lifting and removing fatty substances and particulate impurities to purify the epidermis and hair. Furthermore, it stabilizes oil-in-water emulsions, ensuring uniform dispersion of oil droplets throughout a product, and aids in the formation of lather.

Stability
Aqueous solutions of this ingredient exhibit an alkaline pH, typically ranging from 9.0 to 10.5, due to partial hydrolysis. While stable under standard storage conditions, it is susceptible to oxidation.
Conflicts
- Hard water containing divalent cations (e.g., Ca²⁺, Mg²⁺), as it forms insoluble precipitates (soap scum) through ion exchange, thereby reducing its effectiveness and potentially leaving residues.
- Strong oxidants, particularly in solid form, which can pose a combustion risk.
Safety
Safety Profile
The CIR Expert Panel concluded that all coconut oil-derived ingredients, including Sodium Hydrogenated Cocoate, are safe for use in cosmetic and personal care products. Clinical assessments indicated no significant skin or eye irritation and a very minimal risk of sensitization. This ingredient is also approved for use in products marketed within the European Union.
