Lactose CAS 63-42-3

Lactose is a white crystalline powder, slightly sweet, naturally occurring in mammalian milk.It is mainly used as a food additive (e.g. milk powder, confectionery), a pharmaceutical excipient (tablet filler) and a component of culture media, where its low solubility and mild sweetness properties are prominent.It should be stored in moisture-proof condition, and should be avoided by lactose intolerant people.
