The metabolites investigated were dimeric phloroglucinol derivatives, benzophenones
The cinnamates, salicylates and benzophenones
are small molecules that penetrate the skin and do not adequately protect against UVA.
, 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.
Of the monohydroxylated benzophenones
, 3-hydroxybenzophenone was more potent than 4-hydroxybenzophenone, and 2-hydroxybenzophenone was inactive in the MMP assay (Figure 4A).
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.
and benzotriazoles are among the two most widely used UV light absorbers and they act by absorption of UV light and provide effective resistance for short term exposures.
, benzotriazoles, and HALS include Lowilite 20, 20S,22, and 24 hydroxy-benzophenones
The composition combines the beneficial synergistic effects of polyisoprenylated benzophenones
, stilbenes and anthocyanins to enable weight loss.
Generally, as a possible way to solve the problem of POM photostabilization, a series of ultraviolet (UV) stabilizers have been successfully used to prevent polymeric materials from aging induced by sunlight, such as benzophenones
, benzotriazoles, triazines, and hindered amine light stabilizers.
12) In fact, the very commonly used benzophenones
and salicylates demonstrate more antiandrogenic activity than that of flutamide, the antiandrogen drug given to prostate cancer patients to stop the influence of testosterone in the effort to slow prostate cancer growth.
developed fibers of PPS copolymers or blends that can incorporate stabilizers such as ultraviolet absorbers including benzophenones
Its relationship with Viachem, a supplier of specialty and fine chemicals, enables the company to increase market share for its MAXGARD brand of substituted benzophenones
, according to Jimmy Wooten, global product manager for Syrgis Performance Specialties.
