Detergents
Stearic acid
Formula:
С₁₇Н₃₅COOH
GOST/CAS:
CAS 57-11-4
Stearic acid (cetylacetic acid) is one of the most common saturated fatty acids found in nature. It is a solid, waxy, white or slightly cream-colored substance that is insoluble in water but highly soluble in organic solvents. In the production of detergents, soaps, and cosmetics, it serves as a key structuring agent, emulsifier, and stabilizer, providing finished products with the necessary density, creamy texture, and premium market appearance.
Applications
Soap and Solid Detergent Manufacturing: Used in the form of its sodium salt (sodium stearate). It imparts the necessary hardness to bar soaps, prevents them from softening or melting in soap dishes, and ensures a rich, stable lather.
Cosmetic Industry: Utilized as an emulsifier and thickener in creams, lotions, hair balms, and masks. It binds the water and oil phases together, creating a smooth, homogenous, and silky texture.
Household and Industrial Chemicals: Incorporated into liquid detergents, car shampoos, cleaning pastes, and polishes. It regulates system viscosity and enhances the wetting capability of the formulations.
Specialized Technical Applications: Used in candle making (to increase hardness and burn time), as a plasticizer in the rubber industry, and as a lubricant component in textile manufacturing.
Key Advantages
Excellent Structuring Properties: Efficiently thickens oil and emulsion systems, giving creams, pastes, and soap bars an ideal shape and smooth finish.
Emulsion Stabilization: Prevents the separation of complex multi-component formulations (creams, emulsions) during long-term storage and temperature fluctuations.
Enhanced Sensory Profile: Acts as an emollient, leaving a pleasant velvety feel on the skin while protecting the epidermis from moisture loss and the harsh effects of surfactants (surfactants/surfactants).
Eco-Friendly and Biodegradable: Derived from natural sources (vegetable or animal fats), the product is fully biodegradable, non-toxic, and completely safe for both human health and the environment.
Storage & Transportation
