Use of mixtures of polyglycerol fatty acid esters as emulsifiers in cosmetic and pharmaceutical compositions.

摘要

Use of mixtures of polyglycerol fatty acid esters obtainable by partial esterification of polyglycerol mixtures composed of

  0 to 5% by weight of monoglycerol,
  15 to 40% by weight of diglycerol,
  30 to 55% by weight of triglycerol,
  10 to 25% by weight of tetraglycerol,
  0 to 15% by weight of pentaglycerol,
  0 to 10% by weight of hexaglycerol and
  O to 5% by weight of higher polyglycerols
with at least one saturated fatty acid with 12 to 22 C atoms or at least one unsaturated fatty acid with 16 to 22 C atoms, where the unsaturated fatty acid or fatty acid mixture employed can also contain up to 10% by weight of saturated fatty acids with 16 to 22 C atoms, and the degree of esterification of the saturated or unsaturated fatty acids in the mixture is between 20 and 70%, as emulsifiers in cosmetic and pharmaceutical compositions.
