Hydroxypropyl-β-Cyclodextrin

Hydroxypropyl-β-Cyclodextrin 1.Appearance: White powder; 2.Molecular formula: C42H70-XO35（CH2CHOH-CH3）X ; 3.Molecular weght:1135+58X; 4.CAS No.:128446-35-5 ; 5.Spec: 99%; 6.Store: Cool and dry, avoid light, avoid high temperature place; 7.Packaging：1kg/bag 10kg/barrel,or customized. Broke the beta cyclodextrin annular hydrogen bond in the molecule, while maintaining the cyclodextrin cavity to overcome the main shortcoming of beta cyclodextrin water-soluble difference. 1, In the field of food, spices, can enhance the stability of molecular nutrition and long-term, can cover up or rectify bad odor and taste of food nutrients, can improve production process and product quality. The product has a good solubility in water, substitution degree 4 and above can be arbitrary proportion immiscible with water, can be dissolved in 50% ethanol and methanol. 2, In the cosmetics raw materials used as stabilizers, emulsifiers, to taste, etc., can reduce the organic molecules in the cosmetics mucosal stimulation to the skin, enhance the stability of active ingredients, to prevent the volatilization of nutrients, oxidation. It has a certain relative hygroscopicity. 3, In the pharmaceutical industry, due to the relatively lower surface activity and hemolysis activity and no irritation to muscle, so it is an ideal injection solubilizer and drug excipients. Can improve the difficult solubility in water, soluble drugs increase drug stability, improve drug bioavailability, increase the curative effect of drugs or reduce the dose, can adjust or control of drug release rate, reduce the drug side effects. Can be used to oral medications, injections, mucosal drug delivery systems (including nasal mucosa, rectum, cornea, etc.) drug delivery systems, transdermal absorption, lipotropy targeted drug carrier, also can be used as protective agent and stabilizer of the protein.
