Partially Hydrolyzed Polyacrylamide Ion Polymers
Hydrolyzed polyacrylamide is an anionic polyelectrolyte, carriying plenty of negative charges along the polymer chain. Although polyacrylamide is a nonionic polymer, the hydrolysis can occur readily, converting some of the amide groups to carboxylate ions. This gives an anionic polyelectrolyte with a charge density, depending on the degree of hydrolysis and pH value of the solution. The

How to Choose the Best Partially Hydrolyzed (Gentle
2019-09-17· The term “partially hydrolyzed” simply refers to the size of the proteins. So you can have a whey and casein blend that is partially hydrolyzed (like Enfmail’s options) and you can have 100% whey that is partially hydrolyzed (like Similac and Gerber’s options). Here there is no right choice either. I just encourage you to think about
