Products Description of DL-Mandelic acid 99% CAS#90-64-2Mandelic acid is a large molecular weight fruit acid that is lipophilic. 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 penetration rate into Chemicalbook skin will be slower, which means that it is less irritating than glycolic acid. Its fat solubility is increased and the ability of stratum corneum to penetrate the skin is improved.
