Polymers of acrylic esters containing long chain alkoxylated hydrocarbonoxy-groups and use thereof in cosmetics and personal care.

摘要

The polymers can be obtained by transesterification of polyacrylates obtained by free-radical polymerisation, it being possible for up to 50% of the acrylic esters to be replaced by corresponding methacrylic esters, with polyoxyalkylenemonools of the general average formula
<>R<1>O-(CnH2nO-)xH

  R<1> = alkyl, alkenyl or alkylphenyl radical,
  n = 2,3 or 4 absolute and on average 2.0 to 2.5,
  x = 10 to 200.

The compounds can be used as emulsifiers, solubilisers and for thickening aqueous solutions containing anionic surfactants, especially in cosmetics and personal care.
The compounds are distinguished by a reduced content of low molecular weight compounds, compared with products obtained by copolymerisation.
