● 1,3-Dihydroxyacetone can be used in the following fields: 1. Used in the cosmetic industry Dihydroxyacetone is mainly used as a formula raw material for cosmetics, especially as a sunscreen with special effects, which can prevent excessive evaporation of skin moisture, and play a role in moisturizing and moisturizing. The role of sunscreen and protection against UV radiation. In addition, the ketone functional group in DHA can react with the amino acids and amino groups of skin keratin to form brown polymers, which can give people an artificial brown color, so it can also be used as a sun-tanned skin tone simulator, resulting in a similar appearance to the skin. Prolonged exposure to sunlight results in a brown or tan skin that looks beautiful. 2. Improve the lean meat rate of pigs Dihydroxyacetone is an intermediate product of glucose metabolism and plays an important role in the process of glucose metabolism,
● Pharmaceutical intermediates, chemical raw materials and food additives. As a pharmaceutical intermediate, dihydroxyacetone can synthesize some drugs for the treatment of cardiovascular diseases; dihydroxyacetone can be used in cosmetics, which can prevent excessive evaporation of skin moisture, moisturize the skin and protect the skin from UV radiation.
