Description

Sodium Stearate is the sodium salt of stearic acid, a versatile white solid widely used as an emulsifier, thickener, and stabilizer. Its primary value lies in its ability to create stable emulsions and modify the viscosity and texture of various formulations. This compound is essential for manufacturers in the personal care, pharmaceutical, food, and plastics industries seeking reliable and effective processing aids.

Application

• Cosmetics & Personal Care: Acts as a key opacifying agent, emulsifier, and viscosity builder in creams, lotions, soaps, and deodorant sticks.
• Pharmaceuticals: Used as a tablet and capsule lubricant, binder, and as an emulsifying agent in topical ointments and creams.
• Food Industry (FCC Grade): Functions as an emulsifier, binder, and anti-caking agent in various food products.
• Plastics & Polymers: Serves as an acid scavenger, lubricant, and release agent in the production of PVC and other polymers.
• Industrial Applications: Employed as a waterproofing agent for textiles and paper, and as a component in greases and metalworking fluids.
• Candle Making: Used to harden candles and improve their burning characteristics.
