Introduction:
Lanolin oil is a secretion from sheep's skin. It's similar to human sebum, an oil secreted by the sebaceous glands that you may notice particularly on your nose. Unlike sebum, lanolin contains no triglycerides. Lanolin is sometimes referred to as "wool fat," but the term is misleading because it lacks triglycerides needed to be considered a fat. The purpose of lanolin is to condition and protect sheep's wool. This conditioning property is why the substance is now widely used in human cosmetics, skin care, and hair products. Lanolin oil is extracted by putting sheep's wool through a centrifuge machine that separates the oil from other chemicals and debris. The process is performed after the sheep is sheared so the extraction of lanolin causes no harm to sheep.
Application:
lanolin is an emollient with moisturizing properties and an emulsifier with high water-absorption capabilities. It forms a network on the skin's surface rather than a film, as is the case with petrolatum (Vaseline.). While long-term studies associate a low incidence of allergic reactions to lanolin, it remains a controversial ingredient based on a potential pesticide content and potential comedogenicity. There is a move among high-quality lanolin manufacturers to produce low-pesticide lanolin and among high-quality cosmetic formulators and manufacturers to use the purist form available. Lanolin's comedogenicity potential is increasingly debated as some researchers believe it to be inaccurate, especially when lanolin is used in an emulsion. Lanolin is a sheep's wool derivative formed by a fat-like viscous secretion of the sheep's sebaceous glands. Some consider it a natural wax.
