CAS 5466-77-3: octyl P-methoxycinnamate

Description:Octyl P-methoxycinnamate, also known as octinoxate, is an organic compound commonly used as a UV filter in sunscreens and cosmetic products. It is characterized by its ability to absorb UVB radiation, thereby protecting the skin from sunburn and potential skin damage. The substance has a relatively low molecular weight and is lipophilic, which allows it to be easily incorporated into various formulations. Octyl P-methoxycinnamate is typically colorless to pale yellow and has a mild, pleasant odor. It is stable under normal conditions but can degrade when exposed to prolonged sunlight, which may reduce its effectiveness as a UV filter. The compound is generally considered safe for use in cosmetics, although some studies have raised concerns about its potential for skin irritation and endocrine disruption. Regulatory agencies have established guidelines for its concentration in cosmetic products to ensure consumer safety. Overall, octyl P-methoxycinnamate plays a significant role in photoprotection, making it a popular ingredient in sun care formulations.
