Understanding Lanolin Anhydrous (CAS 8006-54-0)

Lanolin Anhydrous, identified by CAS number 8006-54-0, is a complex natural substance derived from the wool of sheep. Often referred to as wool grease or wool fat, it is obtained during the scouring process, which cleans the raw wool fibers. Unlike other animal fats, lanolin is a wax, composed primarily of esters of fatty acids and alcohols. The term 'anhydrous' signifies that it has been processed to remove water content, resulting in a highly concentrated, semi-solid material that is yellowish in appearance, ranging from a colloid to a soft ointment depending on temperature.

Key Properties and Benefits

The unique composition of Lanolin Anhydrous grants it exceptional properties that make it highly valued across various industries. It is a powerful emollient, meaning it softens and smooths the skin, helping to reduce dryness and flaking. Its ability to form a protective barrier on the skin's surface aids in preventing moisture loss, acting as an effective moisturizer. Furthermore, lanolin possesses excellent water-absorbing capabilities, capable of holding up to twice its weight in water, forming stable water-in-oil emulsions. This emulsifying property is critical in the formulation of many creams and lotions. Its lipophilicity allows it to blend well with other oily ingredients, while its dispersing properties help distribute active compounds evenly within a formulation. These combined attributes – moisturizing, emollient, water absorption, lipophilicity, emulsifying, and dispersing – underscore its versatility.

Diverse Applications Across Industries

Lanolin Anhydrous is a cornerstone ingredient in numerous product formulations. Its most prominent applications are found in the cosmetics and personal care industry. It serves as a vital raw material for producing a wide array of skin care products, including cold creams, anti-wrinkle creams, anti-cracking creams, body lotions, and hand creams. It is also used in hair care items such as shampoos and conditioners, as well as in lipsticks and high-end soaps, where its emollient properties contribute to product performance and feel. As a water-in-oil emulsifier, it provides stability and texture to many cosmetic emulsions.

Beyond cosmetics, Lanolin Anhydrous holds significant importance in the pharmaceutical industry. It is frequently used as an excipient in topical medications, such as ointments and creams, where its emollient base facilitates the delivery of active pharmaceutical ingredients and soothes irritated skin. Its compatibility with skin and low sensitization potential make it a preferred choice for many dermatological preparations. Additional applications extend to the leather industry, where it acts as a conditioning agent, and even in certain agricultural products.

Quality Standards and Sourcing

The quality of Lanolin Anhydrous is critical, especially for cosmetic and pharmaceutical applications. Manufacturers adhere to stringent standards to ensure purity and safety. Common quality standards referenced for Lanolin Anhydrous include those outlined in pharmacopoeias such as the United States Pharmacopeia (USP), European Pharmacopoeia (EP or Ph. Eur.), and British Pharmacopoeia (BP). These standards specify limits for impurities, such as water content, acid value, saponification value, pesticide residues, and other contaminants, as well as testing for identification and physical properties like drop point and color. Suppliers must demonstrate their ability to meet these specifications consistently.

Sourcing high-quality Lanolin Anhydrous requires partnering with reliable suppliers and manufacturers who follow robust refining processes. These processes typically involve reducing free fatty acids, soaps, and water content, eliminating contaminants through various purification steps, and often deodorizing and bleaching the product to meet specific aesthetic and purity requirements. Typical packaging for bulk supply is in drums, such as 220kg drums, facilitating industrial use.
