822-16-2
Product name:Sodium stearate
English alias: Stearic acid sodium salt; Sodium octadecanoate
CAS: 822-16-2
Molecular formula: C18H35NaO2
Appearance: White fine powder
Package: 20kg/bag
It is the sodium salt of stearic acid, widely used as a surfactant, emulsifier, and stabilizer in various industries. It is a key ingredient in the production of soaps, cosmetics, and pharmaceuticals due to its excellent cleansing and thickening properties. This compound appears as a white, odorless powder with a slight fatty odor and is soluble in hot water. Its chemical formula is C₁₇H₃₅COONa, and it is derived from natural vegetable or animal sources, making it biodegradable and environmentally friendly.

1. Soap and Detergent Industry: Primary ingredient in bar soaps, shaving creams, and laundry detergents for its foaming and cleansing properties.
2. Cosmetics and Personal Care: Sodium stearate used as an emulsifier and thickener in creams, lotions, and makeup products.
3. Pharmaceuticals: Sodium stearate serves as a binder and lubricant in tablet formulations and as an emulsifier in ointments.
4. Food Industry: Functions as an anticaking agent and emulsifier in food products (e.g., powdered foods).
5. Plastics and Rubber: Sodium stearate acts as a release agent and lubricant in plastic molding and rubber processing.
6. Textile Industry:Sodium stearate used as a softening agent and water repellent in fabric treatments.
7. Construction: Functions as a waterproofing agent in cement and plaster formulations.
Sodium Stearate is generally recognized as safe (GRAS) by the FDA for use in food and cosmetics. It is non-toxic, biodegradable, and non-irritating to the skin under normal use conditions. Avoid inhalation of dust and direct contact with eyes. Prolonged exposure to dust may cause respiratory irritation.
Storage requirements:
Store in a cool, dry, and well-ventilated area away from moisture and strong oxidizers.
Keep containers tightly sealed to prevent absorption of moisture and clumping.
Recommended storage temperature: below 25°C.
Packaged in 20 kg kraft paper bags with inner polyethylene lining.
Also available in 500 kg or 1000 kg jumbo bags for bulk orders.
Classified as non-hazardous for transport under international regulations (e.g., UN Non-Hazardous).
