Abstract
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.
Claims22
Method of preparing a detergent or cleanser comprising the step of adding to said detergent or cleanser, an isosorbide ether according to general formula (I)
- wherein R′ and R″ independently from each other represent a hydrogen atom or a C6-C33 alkyl- or a C6-C33 unsaturated alkenyl moiety, with the proviso that at least one group R′ or R″ is not a hydrogen atom.
A method of thickening an aqueous surfactant composition comprising the step of adding to said surfactant composition, an isosorbide ether according to general formula (I)
- wherein R′ and R″ independently from each other represent a hydrogen atom or a C6-C33 alkyl- or a C6-C33 unsaturated alkenyl moiety, with the proviso that at least one group R′ or R″ is not a hydrogen atom.
An aqueous surfactant composition comprising surfactant and, as thickening agent for said surfactant, an isosorbide ether according to general formula (I)
- wherein R′ and R″ independently from each other represent a hydrogen atom or a C6-C33 alkyl- or a C6-C33 unsaturated alkenyl moiety with the proviso that at least one group R′ or R″ is not a hydrogen atom, in an amount effective to thicken the surfactant composition.
