  • Patent number: 8575372
    Abstract: 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.

  • Patent number: 8546446
    Abstract: Disclosed are isosorbide derivatives according to the following general formula wherein R represent a hydrogen atom, or an alkyl group with 6 to 22 C-atoms, or an acyl group, or a group X—SO3M, and M stands for a cation, a hydrogen atom or an alkali metal atom or an ammonium or an alkylammonium ion, and X represents an alkoxylated derivative (AO)n wherein AO represents a group C2H4O, or C3H6O, or any mixtures thereof, and the index n is zero or 1 to 20, and p represents a number between 1 and 10, preferably between 1 and 4, and the use thereof to prepare cleansers, detergents, personal care compositions, or cosmetic compositions.

  • Patent number: 6482418
    Abstract: The invention relates to new cosmetic and/or pharmaceutical formulations containing (a) dialkyl carbonates corresponding to formula (I): in which R1 is a linear alkyl and/or alkenyl group containing 6 to 22 carbon atoms, a 2-ethylhexyl, isotridecyl or isostearyl group or a group derived from a polyol containing 2 to 15 carbon atoms and at least two hydroxyl groups, R2 has the same meaning as R1 or is an alkyl group containing 1 to 5 carbon atoms and n and m independently of one another stand for 0 or numbers of 1 to 100, and (b) emulsifiers. The formulations are distinguished by particular sensorial properties, the dialkyl carbonates proving to be as effective as the silicone oils which they are intended to replace.
