Description

Stearic Acid, Monoester With Triglycerol is a non-ionic surfactant and emulsifier derived from the partial esterification of triglycerol with stearic acid. This compound is valued for its excellent emulsifying, stabilizing, and conditioning properties in complex formulations. It serves as a key functional ingredient for manufacturers in the personal care, cosmetics, and food industries seeking to improve product texture and stability.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and stabilizer in creams, lotions, and ointments, providing a smooth, non-greasy feel.
• Food Industry Additive: Used as an emulsifier and stabilizer (E-number pending) in certain food products, baked goods, and edible coatings.
• Pharmaceutical Auxiliary: Serves as an emulsifying agent and release modifier in topical pharmaceutical preparations and ointments.
• Industrial Lubricants & Release Agents: Functions as a component in mold release agents, textile lubricants, and plastic processing aids.
• Household & Institutional Products: Employed in the production of polishes, waxes, and cleaning formulations for its stabilizing effect.
