Evaluation of thermal stability and sun protector factor values in vitro in O/W emulsions containing Benzophenone-3 and Avobenzone
(Colegio de Farmacéuticos de la Provincia de Buenos Aires, 2013-12)
The purpose of this work is to study the thermal stability of benzophenone-3 and avobenzone in the presence and in the absence of TiO2, in O/W emulsions for sunscreens products. The emulsions were stored in glass containers ...

A Stability Indicating HPLC Method for the Determination of Benzophenone-3 and Avobenzone in Cosmetic Formulations
(Taylor & Francis, 2013-07)
An accurate, simple, and reproducible liquid chromatographic method was developed and validated for the determination of benzophenone-3 and avobenzone in a cosmetic formulation. The analyses were performed at room temperature ...
Electrocatalytic hydrogenation of acetophenone and benzophenone using palladium electrodes
(Pergamon-Elsevier Science Ltd, 2015-05)
We have studied the electrocatalytic hydrogenation of acetophenone and benzophenone using a) potentiometric titration of adsorbed hydrogen by the organic reactant in excess, b) electrochemical impedance spectroscopy at a ...
Efficiency of 4,4-bis(N,N-diethylamino) benzophenone for the polymerization of dimethacrylate resins in thick sections
The efficiency of 4,4′-bis(N,N-diethylamino)benzophenone (DEABP) for the polymerization of dimethacrylate monomers in thick sections (1–2 mm) was studied. DEABP (λmax = 365 nm) represents a complete initiating system as ...
