The price of propylene glycol has doubled
According to the catalogue of used raw materials for cosmetics (2021 Edition), propylene glycol CAS 57-55-6 and isopropanol are raw materials for cosmetics. Many R & D engineers told Qingyan that propylene glycol is a common basic raw material in the cosmetics industry, and the dosage is large, so it is also commonly known as "big stuff" of cosmetics“ Propylene glycol is a colorless liquid, which is widely used in chemical synthesis, solvent, daily chemical industry, medicine and food industry. In the field of cosmetics, it can be used as moisturizer, softener, solvent and so on. Almost all cosmetics can be used, especially water, milk, cream, mask and other products. Isopropanol is mostly used as a solvent in the cosmetics industry, and its use frequency is less than that of propylene glycol. "
Wang Yong, general manager of a cosmetics company in Shanghai, introduced that propylene glycol is the top three cosmetics raw material used by its factory, and the annual use of propylene glycol is about 50 tons“ The specific usage depends on the products produced in that year. We have a large demand for propylene glycol in mask products. Its factory needs 40-50 tons of propylene glycol a year, "the starting quantity of each purchase is 5 tons."
It can be seen that propylene glycol is of great significance to the cosmetics industry.
It is noteworthy that at the beginning of this year, the price of "big ingredients" of cosmetics dominated by propylene glycol began to rise sharply, and for a time, it was still facing the crisis of shortage (see comprehensive price rise for details)“ Recently, the price of propylene glycol has dropped slightly. At present, it is about 20 yuan per kilogram. But I heard that it would rise again, so I quickly Tun a little. " The person in charge of a factory in Shanghai said.
