Solubility
Appearance: white powder with good solubility in water and can also be dissolved in ethanol and methanol. It has certain relative hygroscopicity. However, the relative surface activity and hemolytic activity are relatively low.
Characteristics and uses
The introduction of hydroxypropyl group breaks the intramolecular cyclic hydrogen bond of cyclodextrin, and overcomes the main shortcoming of poor water solubility of cyclodextrin while maintaining the cavity of cyclodextrin. It is currently the most in-depth research and the most widely used cyclodextrin. One of the dextrin derivatives. Mainly used in the food, pharmaceutical and cosmetics industries.
In the field of food flavors, it can improve the stability and long-term effectiveness of nutritional molecules, and can mask or correct the bad smell and taste of food nutritional molecules. Improve the production process and product quality. The product has good solubility in water, can be miscible with water in any proportion with a degree of substitution and above, and can also be dissolved in ethanol and methanol.
Used as a stabilizer in cosmetic raw materials Emulsifiers, deodorants, etc. can reduce the stimulation of skin and mucous membrane tissues by organic molecules in cosmetics, enhance the stability of active ingredients, and prevent the volatilization and oxidation of nutrients. It has a certain degree of relative hygroscopicity
