Borax powder should not be used internally, but is a key mineral that our body needs. It can be used as a soak and is found in creams, lotions, shampoos, gels, bath salts, and bath bombs. It is an emulsifier, preservative, cleansing agent, and a buffering agent. Commonly used in bath salts, borax has the ability to soften the water, and suspend soap particles in the bathwater. The result is soft, clean, and healthy skin, which is not clogged by the residue of soap particles. When used in collaboration with citric acid in bath bomb or bath salt recipes, the product will produce a fizzing action. It also forms bath or body gel, when mixed with water and guar gum.
