Functions
Skin 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.
Moisturising
Locks in moisture
Traditional Use
A modern synthetic derivative developed to improve the water-solubility and spreadability of macadamia oil in cosmetic formulations. Created in the late 20th century to allow the benefits of macadamia oil to be incorporated into lighter, non-greasy skincare products.
