Patent number: 8575372Abstract: Disclosed are derivatives of isosorbide having formula (I) wherein R? and R? represent hydrogen or a polymeric ether moiety (CH2—CHR1—O)x—H, where R1 represents hydrogen, or an alkyl or alkenyl moiety having 1 to 33 carbon atoms, which is saturated or unsaturated, branched or linear. This polymeric ether moiety can be a homopolymer or a copolymer, with x being the total degree of polymerization (DP). Preferred is a block copolymer composed of monomer A (DP=a), preferably ethylene oxide or propylene oxide, and monomer B (DP=b), preferably a saturated or unsaturated, branched or linear alkyl or alkenyl moiety having 1 to 33 carbon atoms, where x=a+b. x is a number from 0 to 50, with the proviso that R? and R? are not both hydrogen. The isosorbide derivatives are useful as components of detergent, cleanser, cosmetic and agricultural compositions.Type: GrantFiled: September 30, 2009Date of Patent: November 5, 2013Assignee: Cognis IP Management GmbHInventors: Catherine Breffa, Hans-Christian Raths, Thorsten Löhl

Patent number: 8008246Abstract: The application pertains to the use of isosorbide ethers according to general formula (I) wherein R? and R? independently from each other represent a hydrogen atom or a alkyl- or unsaturated alkenyl moiety for the preparation of detergents and cleaners. Preferably R? and/or R? are linear or branched, saturated or unsaturated alkyl or alkenyl moiety containing 1 to 33 C-Atoms. A second, independent embodiment pertains to the use of these compounds as thickener for aqueous/surfactant compositions.Type: GrantFiled: September 3, 2010Date of Patent: August 30, 2011Assignee: Cognis IP Management GmbHInventors: Catherine Breffa, Burkhard Beckedahl, Markus Dierker, Ansgar Behler, Thorsten Lohl
