| General description: | Oxybenzone, also known as benzophenone-3, belongs to the class of aromatic organic UV filters. It is categorized as an endocrine disruptor chemical (EDC) as it can interfere with the endocrine system. It exhibits estrogenic activity through its interaction with the estrogen receptors alpha (ERα) and beta (ERβ). It is a lipophilic, broad-spectrum sunscreen agent which absorbs ultraviolet B (290−320 nm), some ultraviolet A (320−360 nm), and some ultraviolet C (250−290 nm) radiations. It is widely used as an active compound in commercial sunscreens, creams, lotions, lipsticks, perfumes, shower bath, hair sprays, shampoos, and transparent packing material of products. Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. |
| Other Notes: | This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis. |
