Publication number: 20130280190Abstract: Disclosed is the compound of formula known by the name of diethylhexyl butamido triazone, characterised by a low content of impurities deriving from the preparation process, and by low APHA colour values. The compound according to the invention is obtained by reacting cyanuryl chloride with one equivalent of para-aminobenzoic acid, reacting the intermediate obtained with two equivalents of 2-ethylhexyl-4-aminobenzoate, activating the carboxy group, for example by formation of acyl chloride, and final reaction with tert-butylamine. The compound according to the invention is a UV-B filter which can be advantageously used in cosmetic formulations.Type: ApplicationFiled: June 8, 2012Publication date: October 24, 2013Applicant: 3V Sigma S.p.A.Inventors: Francesco Maestri, Luca Bemporad, Ferruccio Berte'

Publication number: 20040236016Abstract: A process is disclosed for producing an acidic superabsorbent polysaccharide derivative, comprising the steps of. (a) crosslinking at least one polysaceharide containing acidic groups, such as carboxymethyl cellulose and/or 6-carboxy stanch, with a crosslinking agent to produce a gel; (b) if necessary, adjusting the pH of the polysaccharide to a value between 3.5 and 5.5; (c) comminuting the acidified polysaccharide gel; and (d) drying the comminuted polysaccharide at elevated temperature. The superabsorbent polysaccharide obtainable by this process has a pH below 5 and provides odour control when contacted with malodorous fluids.Type: ApplicationFiled: June 28, 2004Publication date: November 25, 2004Inventors: Jeffrey Wilson Thornton, Bas Schraven, Harm Jan Thiewes, Dorine Lisa Van Brussel-Verreast, Luca Bemporad, Anne-Mieke Yvonne Wilhelmina Verwiiligen, Arie Cornelis Besemer, Pia Kalentuin
