Produt Introduction
Mandelic acid is a large molecular weight fruit acid with lipophilicity. Compared with the common fruit acid-glycolic acid, mandelic acid has certain antibacterial ability. At the same time, compared with common glycolic acid and lactic acid, its transdermal speed will be slower, which means that it is less irritating than glycolic acid. Its fat solubility increases, and the transdermal ability of the stratum corneum is improved. Like glycolic acid and lactic acid, mandelic acid also has a certain whitening effect.
Effect
- Mandelic acid is used as a preservative.
- Mandelic acid can be used as an intermediate in the pharmaceutical industry, and can also be used as a preservative.
Mandelic acid can be used as a cosmetic addition to whiten and resist oxidation.
