Hydrazones Containing Peruoroalkyl, Peruoroalkoxy and Peruoroalkylthio Substituents.
First used as a preserver to extend the shelf life of paints, varnishes, and other industrial products, benzophenones
were added to sunscreens in the 1950s.
AgNPs (particle size 1-7 nm) were prepared by photoreduction of silver nitrate using 4-(trimethyl ammoniummethyl) benzophenone
chloride/UV system according to a reported method .
Therefore, the above analysis indicates that the UV-stabilizing fragment (benzophenone
) chemically bonded to the copolymer can retain its UV-absorbing ability and that the obtained copolymer has stronger UV resistance at 288 and 323 nm.
is believed to mimic the female sex hormone oestrogen and has been linked to skin reactions in previous studies.
Burlsorb UV300 is a highly effective benzophenone
uv stabilizer for flexible and rigid PVC, PE, PP, TPEs and various coatings.
Highly efficient sulfur-containing polymeric photoinitiators bearing side-chain benzophenone
and coinitiator amine for photopolymerization.
, a sunscreen ingredient, mimics estrogen in the body, which means it is a hormone disruptor.
March 9 - The European Commission has set a maximum level for food packaging printed with inks containing 4-Methylbenzophenone or Benzophenone
after it was found the potentially cancerous chemical was being used on some breakfast cereal boxes.
In particular, avoid: parabens (butyl-, methyl-, and propyl-), PABAs (para-aminobenzoic acid), padimate-O or parsol 1789, and benzophenone
, homosalate or octy-methoxycinnamate (octinoxate).
New cytotoxic coumarins and prenylated benzophenone
derivatives from the bark of Ochrocarpos punctatus from the Madagascar rainforest.
Many contained potentially harmful chemicals like Benzophenone
, homosalate and octyl methoxycinnamate (also called octinoxate), which are known to mimic naturally occurring bodily hormones and can thus throw the body's systems out of whack.
