Astaxanthin (CAS 472-61-7) Cosmetic Raw Material Introduction
Astaxanthin, with the CAS number 472-61-7, is a naturally occurring fat-soluble carotenoid renowned as a "super antioxidant" in the cosmetic industry. Unlike ordinary antioxidants, it exhibits exceptional free-radical scavenging ability—reportedly 6000 times stronger than vitamin C, 800 times than coenzyme Q10, and 100 times than vitamin E. Primarily derived from the microalgae Haematococcus pluvialis through controlled cultivation and extraction, or produced via advanced microbial fermentation technology, this raw material is favored in high-end skincare formulations due to its remarkable anti-aging, photoprotective, and skin-repairing properties.
In cosmetic applications, astaxanthin demonstrates unique biological advantages. It can penetrate the stratum corneum and reach the dermis layer, effectively neutralizing reactive oxygen species (ROS) generated by UV radiation, environmental pollution, and metabolic processes. This prevents collagen and elastin degradation, thereby reducing fine lines, wrinkles, and skin sagging. Meanwhile, it inhibits lipid peroxidation in skin cells, alleviates UV-induced redness and inflammation, and enhances the skin's natural barrier function. For dry, sensitive, or photo-damaged skin, astaxanthin helps replenish moisture, soothe irritation, and improve skin elasticity and luster. It is widely incorporated into anti-aging serums, sunscreens, brightening creams, eye creams, and other skincare products, as well as premium cosmetic bases to boost product efficacy.
