Patent number: 8580952Abstract: A glyoxal and boron free purified cationic polygalactomannan may be prepared by reacting a polygalactomannan flour, a nonionically derivatized polygalactomannan flour, or a mixture thereof, with a cationising reagent, adjusting the pH to be from about 4 to about 6; cross-linking the cationic with glyoxal, and filtering and water washing the cationic polygalactomannan to produce a glyoxalated purified cationic polygalactomannan containing not more than 70% by weight of water. In some cases it may be desirable to introduce a buffering agent to the glyoxalated purified cationic polygalactomannan to regulate the pH to from 8.0 to about 9.5, when measured at 1% (dry matter) in water. In other cases, it may be desirable to remove water to produce glyoxal free purified cationic polygalactomannan in powder form. Such compounds are particularly useful in personal care products.Type: GrantFiled: January 7, 2011Date of Patent: November 12, 2013Assignee: Lamberti SpAInventors: Ugo Pfeiffer, Mauro Tenconi, Eva Baldaro, Valentina Langella, Giovanni Floridi, Giuseppe Li Bassi

Patent number: 5079146Abstract: The present invention relates to a new method of protection of the carboxy group in the chemistry of the compounds of .beta.-lactam type. According to such a method, the carboxy group is protected by being transformed into its corresponding phenyl-acetoxy-methyl ester, which is then removed by an enzymatic route by means of penicillinacylase.In particular, if the .beta.-lactam compound also bears a phenyl-acetamidic substitutent, this latter is simultaneously hydrolysed during the same step of removal of the carboxy function protecting group.Type: GrantFiled: April 4, 1989Date of Patent: January 7, 1992Assignee: Sclavo S.p.A.Inventors: Claudio Fuganti, Eva Baldaro, Daniela Faiardi, Ameriga Lazzarini
