Acetyl Mandelic Acid
What is Acetyl Mandelic Acid?
Acetyl mandelic acid is an ester derivative of mandelic acid, an alpha-hydroxy acid originally sourced from bitter almonds but typically produced synthetically for cosmetics. Its acetyl group improves stability and lipophilicity compared to the parent acid, aiding incorporation into various formulations. In skincare products, it belongs to the category of pH-regulating agents. It functions by adjusting acidity levels or buffering to keep pH steady, which optimizes active ingredient performance, boosts preservative activity, enhances product shelf life, and ensures mildness on application. This controlled pH environment promotes formula integrity without aggressive shifts, making it ideal for toners, serums, and cleansers requiring precise acid-base balance for user comfort and efficacy.
