Descrizione generale

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.

Applicazioni

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.
