Propylene glycol suppliers in China produce Propylene glycol used in cosmetics and food industrial,Propylene glycol has many efficacies, and Propylene glycol suppliers in China produced it used in chemical industrial.
Propylene glycol, divided into 1,2 propylene glycol and 1,3 propylene glycol, the most widely used in the market is 1,2 propylene glycol, CAS No. 57-55-6, in the normal state is a colorless viscous liquid, almost tasteless, close to sweet, the current production process is mostly made of propylene oxide water, the price of the product directly receives the price of propylene oxide. According to the relevant domestic laws and regulations, according to the qualifications, it can be classified into industrial grade, food grade and pharmaceutical grade, and relevant qualifications can be used in relevant industries.
Glycerol, the national standard is called: glycerin, CAS No. 56-81-5, under normal conditions, it is a colorless viscous liquid, odorless, sweet, absorbs moisture in the air, and has strong moisture absorption and moisturizing properties.
