Borax casein

Description

A type of casein paint that is hydrolyzed using borax. Borax-casein is prepared by soaking casein powder in water with commercial borax. Borax produces a stable emulsion that is slightly alkaline. Borax casein has a lower pH (7.0-7.8) than lime casein (9.0-9.9), and ammonium casein (8.0-9.0). A preservative, such as phenol or p-chloro metacresol, is often used to eliminate biological growth in the solution.
