The L-mandelic acid powder is one of the derivatives of mandelic acid. (S) - (+) - mandelic acid, as a lipophilic acid, has a higher affinity for skin, stronger permeability, and a milder effect than glycolic acid. The main functions of this product in cosmetics and skin care products are whitening and freckling, exfoliating, and antibacterial agents. The risk coefficient is 1. It is very safe and has no acne. It can be used with confidence, and generally has no impact on pregnant women.

The research purpose of this product
The L-mandelic acid powder is prepared from acetophenone, a byproduct of phenol production from cumene. It is mainly used in organic synthesis and the pharmaceutical industry. It is a multi-purpose reagent, used for the resolution of racemates and the preparation of amides. It is an important chiral resolution compound.
What is chiral resolution?
We know that life is composed of carbon. When carbon atoms form organic molecules, four atoms or groups can form a three-dimensional spatial structure through four covalent bonds to form chiral carbon atoms. Because of the different atoms or groups connected, it will form two kinds of molecular structures. These two molecules generally have the same physical and chemical properties. For example, they have the same boiling point, solubility, and spectrum. But judging from the composition and shape of molecules, they are still two kinds of molecules. This situation seems to correspond to each other like the objects inside and outside the mirror. At the same time, because of its three-dimensional structure, its optical isomers will not coincide no matter how they rotate.
The L-mandelic acid powder as a chiral acid resolution agent of common amine compounds can be separated by crystallization by taking advantage of the large difference in physical properties of diastereomers when you encounter that the racemate interacts with another chiral compound to form a mixture of diastereomers.
What are the effects of mandelic acid in skin care?
The L-mandelic acid powder is a second-generation fruit acid. Its benzene ring structure enhances lipophilicity, has high affinity with the skin, and is easy to penetrate the stratum corneum, but does not touch the pain receptors quickly. In view of this, this ingredient is mild and nonirritating and can be used for different skin types. After the use of mandelic acid, it is not easy to produce side effects such as redness, burns, and scabs caused by the first generation of fruit acid, nor is it easy to have sunlight turning black. What's more, mandelic acid is extremely friendly to oily skin, which can effectively regulate sebum, inhibit bacteria and treat acne.
