Buttermilk Powder

Buttermilk Powder is a spray-dried dairy ingredient derived from the liquid byproduct of butter churning, rich in lactic acid, milk proteins, and phospholipids. In cosmetic formulations, it provides gentle exfoliation through natural alpha-hydroxy acids while delivering moisturizing proteins and minerals that help soften and condition the skin. Formulators value it for its traditional skincare heritage and its ability to provide both humectant properties and a creamy, luxurious sensory profile in bath products, masks, and cleansers.
