Product Introduction
Curcumin
CAS No.: 458-37-7
Main Functions
Yihe Biomedical Curcumin is one of the several recognized molecules extracted from turmeric. CAS No. of this compound is 458-37-7. Supplied content of 95% allows people what they need the most: a highly purified turmeric-derived compound for their formulation work under control. Other than simply a turmeric powder, this product has a well defined active-content profile; it will help a formulator manage dosage, color contribution, and batch-to-batch consistency very efficiently.
After thorough consideration of all information available on Curcumin made by Yihe Biomedical, the major biological functions of this compound are its anti-inflammatory, antioxidant, antibacterial, anticoagulant, and anti-platelet aggregation activities. Its vibrant natural color and evident botanical origin make it a good candidate for products where the identity of turmeric is an important part of the product image. Those who are making functional foods, cosmetics, or pharmaceutical-related products will find Curcumin useful both as a well-established plant-based component and as a high-concentration raw material for further processing.
Application Areas
Pharmaceuticals, cosmetics, and food additives are leading industries where Curcumin is used. In case of food additives, it can be used for products that need turmeric-derived ingredients and natural color traits. Cosmetic product ideas related to addition of botanical antioxidant can be supported by Curcumin. When it comes to pharmaceutical products and their development, customers perform their own evaluation based on their formulation knowledge and metrology standards.
Since Curcumin has a very strong yellow-orange color and can visually change the appearance of the final products, it is suggestive to do a pre-production testing. You may consider verifying the dispersion, solubility, color performance, and ingredient compatibility and after confirming the bulk purchase also processing stability.
