Butyris Lac Powder

What is Butyris Lac Powder?

Butyris Lac Powder is the dehydrated form of buttermilk, the liquid whey byproduct from churning cow's milk into butter. This natural dairy derivative contains proteins like lactoglobulins, lactose, lactic acid, vitamins such as B-complex, and minerals including calcium and potassium. Primarily used in rinse-off and leave-on cosmetics like lotions, creams, shampoos, and conditioners, it serves as a conditioning agent. In formulations, it adheres to skin and hair shafts, creating a lightweight film that locks in hydration, minimizes surface friction, and enhances tactile qualities. Its humectant and emollient actions help restore barrier function without heaviness, making it ideal for daily personal care products seeking mild, nourishing effects from traditional sources.
