1, 2-hexanediol is an important chemical raw material, which is widely used in inks for color inkjet printers, advanced cosmetics and synthetic raw materials for the pharmaceutical industry. At present, Chinese patents related to the application of 1, 2-hexanediol were mostly applied in China by companies from Japan, the United States and Germany before 2011. After 2014, the number of patent applications of Chinese companies or individuals increased, but most of them only involved cosmetics.
2. Application in cosmetics
1, 2-hexanediol is added to daily products and used as a preservative in contact with human body. It has the effect of sterilization and moisturizing without negative effects on human health. Many patents or articles mentioned that 1, 2-hexadiol and other substances with antimicrobial effects can play an antimicrobial role. P&g adds 1, 2-hexaneol to its deodorants and antiperspirants. The deodorants/antiperspirants are better at deodorizing/antiperspirants, with better skin feeling, transparency and mildness.
Assosofleur of the United States adds 1, 2-hexanediol to its eyelid lotion, and Chivata Inc. and Japan's Fangke Company add 1, 2-hexanediol to skin care compositions in place of other germicidal preservatives. Dow Global USES 1, 2-hexadiol instead of alcohol in its fragrances, both to reduce irritation to the skin and to provide a more stable product with less surfactant due to its excellent solvent and solubilizing ability. Chinese cosmetics companies have also added 1, 2-hexanediol to their cosmetics, which is antiseptic and less irritating to the skin, improving the safety of skin care products.
3. Application in the pharmaceutical industry
1, 2-hexadiol is mainly used as chemical raw materials in the pharmaceutical industry, which provides a basis for the development and utilization of downstream products.
4. Other applications
1, 2-hexanediol can be used in advanced coatings, senior glue, binder, etc., and is also an intermediate in organic synthesis. It can produce downstream products such as 1, 2-hexanediol and amino alcohols.
