General description

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.

Application

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.
Can be used as a photoinititator in cell encapsulation applications.

The Progress in Development of Dental Restorative Materials

Composite materials based on methacrylate monomers are used to provide aesthetic and functional restoration of dental tissue. Polymerization chemistries are being developed to improve the reliability of these 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
