What are ammonium hydroxide and ammonium thioglycolate

Characteristics that can only be determined by a chemical reaction and a chemical change

A 7 on the pH scale is

All hair color products , texturizers, shampoos are

Substances that allow oil and water to mix, or emulsify, it is a contraction for surface acting agent
