INCI: Boric acid

What is Boric acid?

Boric acid is a colorless, odorless compound available as white crystals or granules or powder. It is usually synthesized by reaction of Sulphuric acid with borax.

Use & Benefits:

Boric acid is bacteriostatic in nature, but its use in cosmetics is unclear since there is a mixed review for its safety for use. It is used as a buffering agent in talc and other baby products. It is also used as a preservative in eye creams, liquid powders, after-shave liquids, skin fresheners to name a few.
