Description

2-Monostearin is a high-purity monoglyceride derived from stearic acid, serving as a versatile non-ionic surfactant and emulsifier. Its unique amphiphilic structure provides excellent stability and texture-modifying properties, making it a critical functional ingredient in numerous formulations. This product is essential for manufacturers in the food, pharmaceutical, and personal care industries seeking reliable performance and consistent quality.

Application

• As a primary emulsifier and stabilizer in food products like margarine, shortening, and whipped toppings.
• Functioning as a co-emulsifier and consistency agent in cosmetic and personal care creams, lotions, and ointments.
• Utilized as a plasticizer and lubricant in the production of plastics and polymer films.
• Acting as an excipient and bioavailability enhancer in pharmaceutical tablet coatings and drug delivery systems.
• Serving as an anti-fogging agent and lubricant in the manufacturing of PVC and other packaging materials.
• Used in industrial applications as a mold release agent and processing aid.
