Avobenzone is a highly effective UV absorber and is used as light stabilizers in plastics and light screening agents in cosmetic industry.


Salient Technical Features


•  CSIR-IICT has developed the process for Avobenzone at bench scale.

•  The process is by the condensation of para methoxy acetophenone with methyl para tertiary butyl benzoate using a commercially available catalyst.

•  Quantitative yields and purity matching the market specifications.


Level/Scale of Development

The process for avobenzone is at 1 kg batch size.


Status of Commercialization


The process is ready for demonstration at bench scale and can be scaled up for pilot/commercial plant of capacity 1TPD to 5 TPD.
