Description

Stearyl Citrate is a high-purity, non-toxic ester derived from citric acid and stearyl alcohol, serving as a multifunctional additive. Its primary value lies in its excellent emulsifying, stabilizing, and metal-chelating properties, making it a versatile ingredient for enhancing product performance and shelf life. This compound is essential for manufacturers in the cosmetics, personal care, food packaging, and pharmaceutical industries seeking safe and effective multifunctional agents.

Application

• Cosmetic & Personal Care: Acts as a non-ionic emulsifier, opacifier, and stabilizer in creams, lotions, and deodorants.
• Food Contact Materials: Used as an antioxidant and stabilizer in polymers and plastics for food packaging to prevent oxidation.
• Pharmaceuticals: Serves as an excipient in topical formulations and as a lubricant in tablet manufacturing.
• Industrial Applications: Functions as a corrosion inhibitor and stabilizer in lubricants and metalworking fluids.
• Plastic Additive: Imparts anti-fogging and anti-static properties to plastic films and sheets.
