what is  of  DL-Mandelic acid with cas 90-64-2?

Mandelic acid is a high molecular weight fruit acid with lipophilicity. Compared with the common fruit acid glycolic acid, mandelic acid has a certain antibacterial ability. At the same time, compared to common glycolic acids and lactic acids, its transdermal speed will be slower, which means that the irritation is less than that of glycolic acids. 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.
