Chemical Structure
Basic Info
DL-Mandelic acid， Also known as phenylethanolic acid or amygdalic acid, it is an important organic acid with the chemical formula C ₈ H ₈ O3. It naturally exists in bitter almonds and can also be synthesized chemically. It usually exists in the form of white crystalline powder, slightly soluble in water, and easily soluble in organic solvents such as ethanol and ether.
The structure of DL-Mandelic acid acid combines benzene rings and hydroxycarboxylic acid groups, making it widely used in the fields of medicine, cosmetics, and organic synthesis.
In the field of medicine, DL-Mandelic acid acid is used as a therapeutic drug for urinary tract infections due to its antibacterial and anti-inflammatory properties, especially for inhibiting pathogens such as Escherichia coli.
In addition, DL-Mandelic acid is a key intermediate for the synthesis of vasodilators and anticholinergic drugs.
In the cosmetics industry, DL-Mandelic acid, as a type of alpha hydroxy acid, has a mild exfoliating ability and is commonly used in skincare products to promote skin metabolism, improve dullness and fine lines.
In industry, the chiral structure of DL-Mandelic acid makes it an important raw material for asymmetric synthesis, which can be used to prepare optically pure drugs or fine chemicals.
DL-Mandelic acid derivatives are also widely used in fragrances and food additives. It should be noted that DL-Mandelic acid needs to be stored in a dark sealed container as it is sensitive to oxidation and high concentrations may cause irritation to the skin or mucous membranes.
Overall, the multifunctionality of DL-Mandelic acid makes it an important compound at the intersection of chemistry and industry.
DL-Mandelic acidis a high molecular weight fruit acid with lipophilic properties. Compared with common fruit acids such as glycolic acid, DL-Mandelic acid acid has a certain antibacterial ability.
At the same time, compared to common glycolic acid and lactic acid, its transdermal speed will be slower, which means that its irritation is relatively smaller than that of glycolic acid. Its lipid solubility increases, and the transdermal ability of the stratum corneum is improved. Like glycolic acid and lactic acid, DL-Mandelic acid also has a certain whitening effect.

The role of DL-Mandelic acid in cosmetics
Many consumers see cosmetics containing the chemical substance “DL-Mandelic acid” and are not clear about its efficacy and function. They want to know whether products containing DL-Mandelic acid are good or not. I will introduce the efficacy, effects, and impact on the skin of DL-Mandelic acid.
DL-Mandelic acid is mainly used in cosmetics and skincare products for whitening, freckle removal, exfoliation, and antibacterial purposes. With a risk factor of 1, it is relatively safe and can be used with confidence. It generally has no effect on pregnant women and does not cause acne.
Composition analysis:
DL-Mandelic acid, also known as almond acid, is a high molecular weight fruit acid that can accelerate the metabolism of skin cells, has exfoliating effects, helps reduce fine lines, and removes melanin deposited in the stratum corneum cells, improving pigmentation and whitening effects.
But the effect is slightly inferior to that of hydroxyacetic acid because DL-Mandelic acid has a large molecular weight and weak permeability. Therefore, DL-Mandelic acid has less irritation to the skin and is also suitable for sensitive muscles.
In addition, DL-Mandelic acid can inhibit the activity of bacteria such as Staphylococcus epidermidis and Candida albicans, making it an antibacterial agent. Please note that DL-Mandelic acid has photosensitivity and is recommended for evening care use.
role
DL-Mandelic acid is an alpha hydroxy acid with lipophilic properties. Compared with common fruit acids such as glycolic acid, almond acid has a certain antibacterial ability. Meanwhile, compared to common glycolic and lactic acids, the transdermal speed of almond acid may be slower, which means that its irritability is relatively lower than that of glycolic acid.
The lipid solubility of DL-Mandelic acid increases, and the transdermal ability of the stratum corneum is improved. So, glycolic acid also has the function of unclogging oil in pores and removing acne. DL-Mandelic acid, like glycolic acid and lactic acid, also has a certain whitening effect.
DL-Mandelic acid is suitable for 7 types of skin, including dry skin, tight skin, non pigmented skin, wrinkled skin, tolerant skin, pigmented skin, and oily skin.
