Functions
Hair Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Occlusive
Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.
Locks In Moisture
Traditional Use
A modified form of lanolin alcohol derived from sheep's wool, acetylated in the 20th century to improve cosmetic performance. Created to provide better emollient properties and reduced oxidation compared to non-acetylated lanolin.
