Hangzhou Yihe Biomedical Technology Co., Ltd.
Product Introduction
CAS No.: 21637-25-2
Main Functions
Isoquercitrin, a flavonoid component, is available in 95% and 98% conventional products at Yihe Biomedical. It offers a very specified source of the active ingredient for customers who do not want a broad-range botanical extract but a precise material identity.
Based on Yihe Biomedical's information, Isoquercitrin is typically a pharmaceutical composition for expectorant, cough suppressant, anti-asthmatic, chronic bronchitis, coronary heart disease, and hypertension-related conditions, as well as antioxidant therapy. Its usage is quite different from many well-known antioxidants as it is mostly used for respiratory support products though it is the flavonoid-based antioxidant from which most consumers choose.
Two concentrations 95% and 98% are intended to give customers the liberty to make their formula and costing decisions at different levels. 95% can be a workhorse grade for daily formula development, and 98% grade is meant for very demanding product positions or in-house QC requirements.
Application fields
Isoquercitrin is mostly used in the pharmaceutical industry and is also a food additive and cosmetic ingredient. Pharmaceutical research mainly focuses on formulations related to cough and respiratory comfort products, whereas phlegm management and cardiovascular ancillary applications are listed in Yihe Biomedical materials.
For the food additives customers, Isoquercitrin is a good choice if one of the criteria is a flavonoid ingredient that is well-contained. At the same time, it serves as a plant-based active ingredient and antioxidant in cosmetic product formulations. Therefore, final products with very different requirements regarding dispersion, color, solubility, and processing behavior, so it is recommended to do a sample test before purchasing in bulk.
