It also occurs naturally in the human body as a by-product from turning carbohydrates into energy. Although it’s technically a beta hydroxy acid ingredient, it is primarily classified as an alpha hydroxy acid (AHA) because its hydroxyl group in the alpha position is believed to be dominant to the beta hydroxyl group. Also, it is not known to be oil-soluble like traditional beta hydroxy acid salicylic acid. Malic acid is used in cosmetics to adjust a product’s pH and, in an acidic pH range ideally between 3 and 4, as a mild exfoliant that can be used in lower concentrations (typically between 1–2%) to boost the efficacy of other AHA exfoliants such as glycolic and lactic acids. In foods, malic acid is sometimes added to impart a sour or tart flavour. In its raw form, malic acid appears as white or colourless crystals. It is considered safe as used in leave-on and rinse-off cosmetics. Powiązane składniki: AHA
