Description

Lanolin is a natural, complex mixture of esters, fatty acids, and alcohols derived from the wool of sheep, widely recognized for its exceptional emollient and protective properties. Its primary commercial value lies in its ability to absorb and retain significant amounts of water, forming stable water-in-oil emulsions that protect and moisturize skin and other materials. This makes it a critical ingredient for manufacturers in the cosmetics, personal care, pharmaceutical, and industrial lubricant sectors seeking high-performance, natural-derived raw materials.

Application

• Cosmetics & Personal Care: A key emollient and moisturizer in lip balms, creams, lotions, hair conditioners, and soaps for its occlusive and skin-softening effects.
• Pharmaceuticals: Used as a base for ointments, topical medicinal creams, and protective barriers due to its compatibility with skin and ability to enhance drug delivery.
• Industrial & Metalworking: Serves as a corrosion inhibitor, lubricant additive, and protective coating for metals and machinery.
• Leather & Textile Processing: Acts as a softening and conditioning agent for leather goods and a lubricant for wool fibers during textile manufacturing.
• Adhesives & Polishes: Imparts flexibility, gloss, and water resistance in formulations for shoe polishes, furniture waxes, and specialty adhesives.
• Veterinary & Animal Care: Found in udder balms, wound care ointments, and grooming products for livestock and pets.

Quality Control

Our Lanolin is produced and tested to meet stringent quality standards, including USP, Ph. Eur., and cosmetic-grade specifications where applicable. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as melting point, acid value, saponification value, and water content. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee product integrity and compliance.

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). As the material is easily oxidized, prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal long-term stability. Keep away from strong oxidizing agents and heat sources.
