Science
Mechanism of Action
STEARETH-20 functions by significantly reducing the interfacial tension between immiscible liquids like oil and water, enabling the formation of stable emulsions and preventing product separation. As a surfactant, it effectively lowers surface tension, assisting in the emulsification and dispersion of oils and fats, thereby suspending impurities for easy removal. This ethoxylated ingredient also enhances water solubility for oil-loving compounds and contributes to product texture as a rheology modifier and foam stabilizer.
