Description

A very alkaline colorless, crystalline powder used in tiny amounts to set the pH of cosmetics products to be just right. In larger amounts, it can be a skin irritant (the Cosmetic Ingredient Review panel concluded that sodium borate up to 5% is safe as a cosmetic ingredient, though a 5% solution should not be used on infant or injured skin).
