Sodium stearate(CAS: 822-16-2)

Sodium stearate is a sodium salt of stearic acid, with the chemical formula C18H35NaO2. It is a white, waxy solid that is insoluble in water but soluble in organic solvents. Sodium stearate is commonly used as a surfactant, emulsifier, and soap due to its ability to reduce surface tension and form micelles.

Sodium stearate is widely used in pharmaceuticals as a binding agent and emulsifier, in the food industry as an emulsifier and stabilizer, in cosmetics for foaming and cleansing properties, and in industrial applications such as lubricants and coatings. It is also a key component in the production of soaps and detergents.

Sodium stearate is generally considered safe when used in appropriate amounts and under proper handling conditions. It is non-toxic in moderate exposure and has low irritancy potential. However, direct contact with skin or eyes may cause mild irritation, and inhalation of dust should be avoided. Safety standards and handling precautions should be followed as per regulatory guidelines.

Sodium stearate should be stored in a cool, dry, and well-ventilated place, away from moisture and direct sunlight. It is typically kept in airtight containers to prevent exposure to air and contaminants. Storage conditions should maintain a temperature below 25°C and humidity levels below 60% to ensure stability and prolong shelf life.
