Milk Lipids
What is Milk Lipids?
Milk lipids refer to the fat-soluble components derived from bovine milk, primarily consisting of triglycerides, phospholipids, and sterols that mirror the lipid profile of human skin's barrier layer. Extracted through processes like centrifugation or solvent separation, they belong to the emollient category in cosmetics, commonly found in moisturizers, creams, and lotions. In formulations, milk lipids work by mimicking the skin's natural oils, filling in irregularities on the skin surface to create a smooth texture and enhance product spreadability. They also contribute to barrier support by reducing transepidermal water loss when combined with other conditioning agents, promoting a supple feel without greasiness. Their biocompatibility stems from compositional similarity to sebum, making them suitable for daily skincare applications focused on hydration and comfort.
