Anti-caking agent 1,2-propanediol is an organic compound with the chemical formula C3H8O2, which is widely used in cosmetics, pharmaceutical, food and chemical fields. This article will introduce the properties, preparation methods, uses and market conditions of 1,2-propanediol in detail.
1. Nature. 1,2-propanediol is a colorless liquid with a slight pungent odor. It is absorbent and can absorb moisture from the air, so it needs to be sealed and preserved. 1,2-propanediol has a high boiling point, is not volatile, and can be used as a solvent. In addition, 1,2-propanediol also has the characteristics of good solubility, low viscosity and low toxicity.
Second, the preparation method.
There are two main preparation methods for 1,2-propanediol: chemical synthesis and fermentation. The chemical synthesis method is prepared by using propylene as raw material through oxidation, hydrogenation, dehydration and other steps. The fermentation method is made by microbial fermentation of sugars as raw materials. Both methods can obtain high-purity 1,2-propanediol, but the fermentation method has the advantages of a wide range of raw materials and environmental protection, and has gradually become the mainstream preparation method.
3. Use. 1,2-Propanediol is an important organic solvent that can be used to dissolve many organic compounds and resins. In the field of cosmetics, 1,2-propanediol can be used as a humectant, solvent and stabilizer to improve the moisturizing effect and stability of products. In the pharmaceutical field, 1,2-propanediol can be used as a pharmaceutical solvent and pharmaceutical intermediate to improve the solubility and bioavailability of drugs. In the food field, 1,2-propanediol can be used as a food additive to improve the taste and stability of food. In the chemical industry, 1,2-propanediol can be used to synthesize other organic compounds and resins.
