About
The calcium salt of milk casein — a food-grade conditioning and thickening agent with a very strong safety track record.
Calcium caseinate (CAS 9005-43-0) is the calcium salt of casein, the major milk protein. It is produced by treating casein with calcium hydroxide or calcium chloride. Used as a food ingredient (sports nutrition, meal replacements) and cosmetic ingredient for film-forming, conditioning, and emulsion stabilization. Extensive food-grade safety data; no GHS hazards. Main considerations are its dairy origin (not vegan) and milk-allergen status for highly sensitive individuals. No reproductive, developmental, or carcinogenic concerns identified.
