Science
Mechanism of Action
Functioning as a surfactant, Sodium Soyate's molecular structure enables it to lower the surface tension within liquids, thereby facilitating the stable dispersion of oil and water phases. In cleansing applications, this property allows it to efficiently lift and remove lipid-soluble impurities and particulate matter from the skin and hair. Within cosmetic formulations, it acts as an emulsifier to create stable mixtures and can also contribute to controlling the product's viscosity.

Stability
No specific data regarding optimal pH range or particular stability concerns for Sodium Soyate in cosmetic formulations were identified. Its surfactant and emulsifying properties suggest good dispersibility in aqueous systems.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that fatty acids and fatty acid salts, including those derived from soy (like Sodium Soyate), are safe for use in cosmetics under current practices and concentrations, provided they are formulated to be non-irritating and non-sensitizing. While no specific maximum concentration for Sodium Soyate was provided, safety is contingent on proper formulation to mitigate potential irritation or sensitization. Similar sodium salts of fatty acids are recognized as safe by the FDA for indirect food contact and as food additives.
