A white, odorless powder known as cholesterol NF is made from the grease found in wool. It satisfies the most recent USP Pharmacopoeia requirements with a minimum purity of 95%. A sterol called cholesterol NF is responsible for the lanolin alcohols’ emollient properties. Cholesterol can be found in the lipids that cover the skin’s surface.
Cholesterol NF’s hydrophobic properties make them particularly useful for treating dry, damaged hair as well as irritated, chapped, and dry skin. At concentrations of 1–10%, it works perfectly as an emulsifying agent for creams, lotions, and hair conditioners. Additionally, cholesterol NF can serve as a fundamental component in the production of vitamin D3.
