NOW Foods Citric Acid 4 oz provides food-grade citric acid, a naturally occurring weak acid found in citrus fruits that is widely used as a natural preservative, pH adjuster, and flavor enhancer in home food preparation, canning, fermentation, and DIY bath and body product formulation. Citric acid prevents enzymatic browning in fruits and vegetables, acidifies fermented beverages for proper balance, and acts as a chelating agent in homemade bath bombs to trigger the effervescent reaction. In skincare, it functions as an alpha-hydroxy acid exfoliant and pH balancer in formulations.
