Description

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.

Application

Oxybenzone may be used as a pharmaceutical reference standard in the determination of the analyte in pharmaceutical formulations by spectrophotometric and chromatographic techniques.

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.

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.
