Disclosed are derivatives of isosorbide having formula (1) 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.
