Descripción general

Ethyl 4-(dimethylamino)benzoate (Et-PABA) is a hydrophilic polymer, which can also be used as a derivate of 4-aminobenzoate. It is majorly used as a photo-initiator with a strong estrogenic activity, which finds application as an ultraviolet filter in sunscreens.
Ethyl 4-(dimethylamino)benzoate is a photoinitiator in visible light system.

Aplicación

Can be used as a photoinititator in cell encapsulation applications.
Et-PABA is used as a co-initiator with camphorquinone (CQ) to form a self-adhesive composite for the fabrication of photosensitizers in dental materials.

This work investigates the cytocompatibility of several photoinitiating systems for potential cell encapsulation applications. Both UV and visible light initiating schemes were examined. The UV photoinitiators included 2,2-dimethoxy-2-phenylacetophenone (Irgacure 651), 1-hydroxycyclohexyl phenyl ketone (Irgacure 184), 2-methyl-1-[4-(methylthio) phenyl]-2-(4-morpholinyl)-1-propanone (Irgacure 907), and
