Nonfat Dry Milk
What is Nonfat Dry Milk?
Nonfat dry milk is a dehydrated powder obtained from cow's milk after removing the fat content through processes like skimming and spray-drying. It consists primarily of milk proteins such as casein and whey (around 35%), lactose (about 50%), minerals like calcium and potassium, and trace vitamins including A, D, and E. In cosmetics, it appears in moisturizers, masks, cleansers, and hair conditioners. It functions by forming a protective film on the skin and hair via proteins that reduce friction and static, acting as a humectant to draw moisture, and providing mild buffering from lactic acid components for gentle cleansing. This ingredient supports overall skin barrier maintenance and imparts a soft, supple texture without greasiness due to its fat-free nature.
