  • Patent number: 9562054
    Abstract: A process for preparing isosorbide ethoxylate di(meth)acrylate by transesterifying alkyl (meth)acrylate with isosorbide ethoxylate, comprising the steps of: (i) ethoxylating isosorbide to give isosorbide ethoxylate, (ii) reacting alkyl (meth)acrylate with isosorbide ethoxylate in the presence of potassium phosphate as catalyst and a stabilizer and in the presence of an azeotroping agent which forms an azeotrope with the alcohol bound in the alkyl (meth)acrylate, (iii) continuously distilling off the azeotrope of azeotroping agent and alcohol, wherein steps (ii) and (iii) are conducted simultaneously until the isosorbide ethoxylate has been essentially fully converted, (iv) removing the catalyst from the product mixture comprising isosorbide ethoxylate di(meth)acrylate, (v) distilling unconverted alkyl (meth)acrylate and azeotroping agent out of the product mixture.

  • Publication number: 20140356296
    Abstract: Described are isosorbide derivatives according to general formula wherein R and R?, independently of one another, are: (i) hydrogen atom, or (ii) radical COR?, wherein R? is linear or branched, saturated or unsaturated alkyl radical having 5 to 23 carbon atoms, or (iii) linear or branched, saturated or unsaturated alkyl radical having 6 to 22 carbon atoms, or (iv) radical CH2—CHOH—R??, wherein R?? is linear or branched alkyl radical having 6 to 22 carbon atoms, or (v) radical (CH2—CH2O)n—H and/or (CH2—CH(CH3)—O)m—H, wherein n and m, independently of one another, are an integer or fraction from 1 to 10, or (vi) for radical SO3OX, wherein X represents a sodium or ammonium ion, with the proviso that at most one of the radicals R and R? is a hydrogen atom. The isosorbide derivatives are useful as components of cosmetic compositions.
