Mechanism of Action
As an amphoteric surfactant, SODIUM ISOSTEAROAMPHOPROPIONATE operates through its dual-charged structure, efficiently reducing surface tension. This enables effective emulsification of oils and impurities, leading to thorough cleansing. Beyond its primary cleansing role, it significantly enhances foam generation, provides conditioning benefits for hair, and functions as a hydrotrope, improving the solubility of other ingredients within a formulation.
