Antichaotropic Salts for Stabilizing Cysteine

Antichaotropic salts stabilize cysteine by lowering the water activity in an aqueous solution. This technique can be used to extend the shelf life of cysteine permanent wave solutions.

Using Perfluoropolyether Phosphate to Lower pH without Increasing Skin Irritation

Clinical studies described here show that perfluoropolyether phosphate behaves as a very mild acidic agent, being effective in decreasing the pH without increasing the collateral effects of acidic compositions.
