Carnosic acid was originally found in sage and later found in other Lamiaceae plants, such as Rosmarinus officinalis, which are more abundant and more readily available, so it is currently the main source in the market. Rosemary Leaf Extract contains a variety of active ingredients such as carnosic acid, rosmarinol, rosmarinic acid, carnosol, epirosmarinol, isorosmarinol, and rosemary diphenol. The highly potent antioxidants are carnosic acid, rosmarinol and carnosol.
Rosemary Extract Powder is natural and non-toxic, and its antioxidant effect is much higher than the existing natural antioxidants such as vitamin C, vitamin E, tea polyphenols, etc. It is 2 to 4 times that of synthetic antioxidants BHA and BHT, and it has a stable structure, not easy to decompose, and can withstand high temperatures from 190 ° C to 240 ° C. It completely overcomes the fatal weakness that most natural antioxidants are decomposed at high temperature. Therefore, compared with other similar products, it has the advantage of being more efficient and broad-spectrum.
