Citric Acid
Naturally occurring Citric Acid is a member of the alpha hydroxy acid (AHA) group and in skin care products it is often used as an ingredient in exfoliants and chemical peels, but most often Citric Acid is used to adjust the pH in personal care products such as lotions, cremes, shampoos, etc.
Because citric acid kills bacteria, some fungi, and mildew, it's great for general sanitizing, disinfecting, and cleaning. It's also effective at removing soap scum, hard water stains, calcium deposits, lime, and rust. Also, it serves as a preservative in many cleaning solutions. Because lemon juice contains 5 percent to 8 percent citric acid, it's often used in green cleaning.
Citric acid is used in several cleaning products, such as auto cleaning products (such as wheel and radiator cleaners), metal cleaners, oven cleaners, dishwasher cleaners, all-purpose cleaners, soap-scum removers, bathroom cleaners, tub and tile cleaners, carpet cleaners, dish soaps, laundry detergents, air fresheners, window cleaners, stain removers, and dishwasher rinse aids.
Avoid contact with the eyes and mouth, and do not expose directly to the skin.
