Description

Lanolin is a natural, complex mixture of esters, fatty acids, and alcohols derived from the wool of sheep, valued for its exceptional emollient, moisturizing, and protective properties. Its unique composition makes it an outstanding skin-identical occlusive agent, forming a semi-permeable barrier that prevents moisture loss while allowing the skin to breathe. This versatile material is a critical ingredient for formulators in the cosmetics, personal care, pharmaceutical, and industrial lubricant sectors seeking natural, high-performance raw materials.

Application

• Cosmetic & Personal Care Formulations: A key emollient in creams, lotions, lip balms, and hair conditioners for intense moisturization and skin barrier repair.
• Pharmaceutical Ointments & Topical Preparations: Used as a base in medicated creams and ointments (e.g., USP grade) for its excellent drug-release and skin-adhesion properties.
• Baby Care Products: Employed in diaper rash creams and baby lotions for its gentle, protective action on sensitive skin.
• High-Grade Lubricants & Rust Preventatives: Serves as a natural, non-toxic lubricant for fine machinery and as a corrosion inhibitor.
• Leather & Textile Conditioning: Used to soften and waterproof leather goods and to condition wool fibers.
• Soap Making & Industrial Emulsions: Acts as a superfatting agent in specialty soaps and a stabilizer in various industrial emulsions.

Quality Control

Our lanolin is produced and tested to meet stringent quality standards, including USP, Ph. Eur., and cosmetic-grade specifications. Each batch undergoes comprehensive analysis for key parameters such as melting point, acid value, saponification value, and peroxide value to ensure purity, consistency, and performance. Certificates of Analysis (COA) documenting full compliance are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). As the material is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Keep away from strong oxidizing agents and heat sources.
