Description

Lanolin Fatty Acids CAS NO 8046-72-8 are a complex mixture of fatty acids derived from the purification of wool grease (lanolin). This natural product is valued for its unique composition, which imparts excellent emollient, emulsifying, and skin-protective properties. It serves as a crucial raw material for formulators in the personal care, cosmetic, and pharmaceutical industries seeking natural-derived ingredients. The product is also utilized in industrial applications such as lubricants, metalworking fluids, and textile processing aids.

Application

• Cosmetic & Personal Care Formulations: Key ingredient in creams, lotions, lipsticks, and soaps for its moisturizing and stabilizing effects.
• Pharmaceutical Ointments & Topicals: Used as an emollient base and absorption enhancer in dermatological preparations.
• Industrial Lubricants & Greases: Acts as a friction modifier and additive in specialty lubricants due to its film-forming ability.
• Metalworking Fluids: Provides lubricity and corrosion inhibition in cutting and drawing oils.
• Textile & Leather Processing: Functions as a softener, lubricant, and waterproofing agent for fibers and leather.
• Chemical Intermediate: Serves as a starting material for the synthesis of esters, amides, and other derivatives.

Quality Control

Our Lanolin Fatty Acids are produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency, purity, and performance. Key parameters such as acid value, saponification value, iodine value, and color are monitored against stringent internal specifications. Certificates of Analysis (COA) are provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). This material is easily oxidized; for long-term storage, consider using under an inert atmosphere such as nitrogen. Keep away from strong oxidizing agents and heat sources.
