Lanolin CAS#8006-54-0

Product Details

Lanolin oil is a natural secretion originating from sheep's skin, and its composition closely resembles that of human sebum—the oily substance produced by sebaceous glands, most noticeable on the nose. However, unlike sebum, lanolin contains no triglycerides, which makes the term “wool fat” somewhat inaccurate. Its primary natural role is to moisturize and safeguard sheep's wool. Thanks to these outstanding conditioning and protective qualities, lanolin is extensively incorporated into cosmetics, skincare, and haircare formulations. The oil is recovered through centrifugation of shorn sheep's wool, a method that effectively removes impurities while ensuring no harm comes to the animals.

Lanolin Chemical Properties

Product Usage 

Lanolin acts as a highly effective emollient with strong moisture-retaining capabilities, and also functions as an emulsifier with considerable water-absorbing capacity. Unlike petrolatum (Vaseline), which forms a barrier film on the skin, lanolin creates a breathable, open network across the skin's surface. Long-term studies suggest that allergic responses to lanolin are relatively uncommon; nonetheless, it remains a subject of debate due to potential concerns regarding pesticide residues and possible comedogenic effects. In response, leading lanolin manufacturers are placing greater emphasis on producing grades with low pesticide content, while high-end cosmetic brands prefer to use the purest available forms. The comedogenic potential of lanolin is also undergoing reassessment, with some researchers suggesting that such worries may be exaggerated—particularly when lanolin is used in emulsion formulations. Lanolin is obtained from sheep's wool and is a viscous, wax-like substance secreted by the sebaceous glands of sheep, often regarded as a natural wax.
