Butylene Glycol (BG) is an important raw material for chemical production, which is widely used in medicine, cosmetics, food, plastics, coatings and other fields. This article will detail the properties and uses of butanediol.

1. properties of butanediol

1. Physical properties: butanediol is a colorless, odorless, transparent, viscous liquid, with a high boiling point and flash point, not volatile, with good solubility and hygroscopicity.

2. Chemical properties: Butanediol has a strong alcohol hydroxyl activity, can react with acids, esters, ethers, halogenated hydrocarbons and other compounds to generate the corresponding derivatives. In addition, butanediol also has oxidation resistance and stability.

2. the use of butanediol

1. pharmaceutical field: butanediol can be used as drug carrier and excipient, can improve the stability and solubility of drugs, at the same time with moisturizing, antibacterial, anti-inflammatory and other effects, can be used in the production of drugs and medical devices.

2. cosmetics field: butanediol is a commonly used moisturizing agent, has good moisture retention and permeability, can improve the stability and use effect of cosmetics, widely used in emulsion, cream, essence and other cosmetics.

3. Food field: Butanediol can be used as a food additive, with anti-corrosion, moisturizing, anti-oxidation and other effects, can be used in the production of candy, cakes, beverages and other food.

4. Plastics field: Butanediol can be used as a plastic plasticizer, which can improve the flexibility and processability of plastics, and can be used to produce plastic products such as PVC.

5. Coating field: Butanediol can be used as a coating additive, which can improve the leveling, gloss and adhesion of coatings, and can be used to produce various coatings.

In short, as an important raw material for the production of chemical products, butanediol has a wide range of uses and good performance, and plays an important role in promoting the development of various fields.
