boric

Boric acid is a weak, water-soluble acid that occurs naturally in some minerals, volcanic waters, and hot springs. It is a white, odorless, and crystalline powder that is often used as an antiseptic, insecticide, flame retardant, and in various industrial applications. Boric acid is also commonly used in households as an eyewash, as a preservative for food and cosmetics, and as an ingredient in some laundry and cleaning products. It is considered a safe and effective substance when used properly, but can be toxic in high doses.
