Science
Mechanism of Action
This ingredient functions as a surfactant by reducing the surface tension between immiscible liquids like oil and water, which is critical for forming stable emulsions in various cosmetic products. As a gentle cleansing agent, it effectively lifts and removes impurities and makeup without compromising the skin's natural moisture barrier. Its emulsifying property ensures product stability and consistent texture, while the natural glycerin present in its composition provides emollient and moisturizing benefits, enhancing the skin's feel and hydration.

Stability
Optimal stability is observed in an alkaline pH range of 9.0 to 11.0. Formulators should conduct preliminary compatibility tests, particularly with essential oils, allowing up to 48 hours for the product to achieve clarity. Heating may be required if a clear solution is not achieved within this timeframe.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Potassium Castorate is safe under current practices of use and concentrations, provided it is formulated to be non-irritating and non-sensitizing. For instance, it can be incorporated up to 15% in a soap base formula. While some general hazard statements (H315: Causes skin irritation, H319: Causes serious eye irritation) exist, these typically refer to the raw material at high concentrations, underscoring the importance of careful formulation to ensure safety in finished cosmetic products.
