Lanolin wax is a natural wax derived from sheep wool. It is obtained during the scouring or washing of raw wool to remove impurities. The crude wool grease undergoes refining processes such as solvent extraction, bleaching, and deodorization to produce lanolin wax suitable for cosmetic and pharmaceutical applications [1].
The production process of lanolin wax begins with the collection of raw wool grease from sheep wool. This grease, containing lanolin, is then subjected to solvent extraction to separate the wax components from other impurities. The extracted lanolin wax is further refined by bleaching to improve its color and deodorization to remove any unpleasant odors, resulting in a purified wax ready for use in various applications [2].
Lanolin wax functions primarily as an emollient, providing moisturizing and softening effects to the skin. It forms a protective barrier on the skin’s surface, preventing moisture loss and enhancing skin hydration. Additionally, lanolin wax acts as an emulsifier and stabilizer in formulations, ensuring the uniform distribution of ingredients and improving the overall stability of cosmetic and pharmaceutical products [3].
Lanolin wax is used in a variety of cosmetic products, including creams, lotions, lip balms, and hair care products. In creams and lotions, it provides moisturizing and protective properties, helping to maintain skin hydration and softness. In lip balms, lanolin wax soothes and moisturizes dry, chapped lips. It is also used in hair care products to add shine and improve manageability [4].
Lanolin wax is typically packaged in containers that prevent contamination and moisture absorption, such as airtight plastic or metal drums. During transportation, it should be protected from extreme temperatures and humidity to maintain its quality and stability. Proper labeling with storage and handling instructions is essential to ensure safe handling and storage throughout the supply chain [5].
