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
Lanolin, derived from sheep's wool grease, has been used as an emollient since at least the 19th century. Acetylation was developed in the 20th century to improve stability and reduce stickiness while preserving its conditioning properties.
