Description

Oxystearin is a food-grade chemical additive derived from vegetable oils, primarily functioning as a crystallization inhibitor and viscosity modifier. Its value lies in its ability to control the physical properties of fats and oils, preventing cloudiness and maintaining clarity and texture in finished products. This makes it an essential processing aid for manufacturers in the food, cosmetics, and pharmaceutical industries seeking to ensure product stability and a consistent consumer experience.

Application

• Food Industry: Used as a crystallization inhibitor in vegetable oils and salad dressings to prevent clouding and maintain clarity at low temperatures.
• Confectionery & Fats: Acts as a viscosity modifier and stabilizer in chocolate, margarine, and shortening to control texture and prevent fat bloom.
• Cosmetics & Personal Care: Serves as an emollient and consistency regulator in creams, lotions, and lipsticks to improve skin feel and product stability.
• Pharmaceuticals: Employed as a lubricant and release agent in tablet manufacturing and as a base for ointments and suppositories.
• Industrial Applications: Functions as a plasticizer and processing aid in polymer formulations and as a component in release agents for molds.

Quality Control

Our Oxystearin is manufactured under strict quality systems to meet the rigorous standards of the food and pharmaceutical sectors. Production adheres to principles of Good Manufacturing Practice (GMP), and the product is compliant with relevant global regulations, including FCC (Food Chemicals Codex) and EU food additive specifications (INS 387). Each batch is accompanied by a comprehensive Certificate of Analysis (COA) verifying identity, purity, and safety parameters, available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. As the material is easily oxidized, containers should be kept tightly sealed when not in use to minimize exposure to air.
