They analyzed these samples for chemicals found in beauty products, including benzophenones
, which are ultraviolet filters; parabens, which are antimicrobial preservatives; as well as bisphenol A and chlorophenols.
The analysis revealed that urine samples contained chemicals including parabens and benzophenones
The US study examined mixtures of chemicals - such as parabens and benzophenones
- in personal care products in relation to hormones in healthy, reproductive-aged women using several methods of exposure across the menstrual cycle.
As part of the study, a total of 509 urine samples were collected from 143 women aged 18 to 44 years, free of known chronic health conditions and birth control to be measured for environmental chemicals that are found in personal care products, such as parabens, which are antimicrobial preservatives, and benzophenones
, which are ultraviolet filters.
The analysis of major compounds of propolis showed the presence of diterpenicacids, prenylated benzophenones
, and triterpenes in the propolis obtained from Cundinamarca Antioquia, and Huila regions respectively.
The pharmacologically active components of Rhizoma Anemarrhenae include steroidal saponins, flavonoids, phenylpropanoids, alkaloids, and benzophenones
, with saponins being the major constituents [3-5].
This genus is also reported to be a rich source of xanthones, benzophenones
, flavonoids, biflavonoids and triterpenes showing significant pharmacological activities.
Songwon's UVA portfolio Songsorb[R] CS is a comprehensive range of UV stabilizers that spans from the traditional benzophenones
to the benzotriazoles--known for their extensive utilization scope and also includes the most recent, high-performing triazine UV absorbers.
The metabolites investigated were dimeric phloroglucinol derivatives, benzophenones
, chemical ultraviolet light absorbers used in products ranging from sunscreens and hair sprays to plastic lens filters for color photography, have been named the American Contact Dermatitis Society's 2014 Contact Allergen of the Year.
The first part of the volume is organized by chemical class, covering monoterpenes, sesquiterpenes, triterpenes & steroids, essential oils, phenolic compounds, phenylpropanoids, coumarins, flavonoids, quinones & benzophenones
, xanthones & anthranoids, lignans & stilbenes, tannins, alkaloids, and ceramides & cerebrosides.
, benzotriazoles, and HALS include Lowilite 20, 20S,22, and 24 hydroxy-benzophenones.
