Lactic Casein
Natural Protein Polymers for Technical Applications.

Catalog Number	Q123
Definition	Though commonly regarded as the principal protein in milk, casein is actually a colloidal aggregate composed of several identifiable proteins together with phosphorous and calcium. It occurs in milk as a heterogeneous complex called calcium caseinate. It is a white, tasteless, odorless, hydroscopic, amorphous solid.
CAS Number	9005-46-3
Application	Natural Protein Polymers for technical applications is a high quality grade of casein prepared by acid precipitation of milk. This casein protein polymer may be used in a variety of industries including: Cheesemaking, food and feeds, dietetic preparations, flooring compounds, plastic items, paper coating, textile sizing and fibers, leather, water-dispersed paints for interior use, adhesives (specially for wood laminates) and binder in foundry sands. In the paint industry its chief application is distempers, where it is applied as a colloidal suspension of calcium caseinate. Which becomes insolubilized by drying out and by carbonation. For other end uses, casein is insolubilized by formaldehyde.
