  • C13 - HYDROCARBON MIXTURE AND USE THEREOF
    Publication number: 20240033197
    Abstract: The present invention relates to a specific hydrocarbon mixture comprising at least 95% by weight of saturated linear C-13 hydrocarbon based on the sum of the hydrocarbons in the hydrocarbon mixture, characterized in that the amount of C11/C12 is 0.05 to 1.5% by weight based on the sum of the hydrocarbons in the hydrocarbon mixture and the amount of C14 to C17 is 0.2 to 3.5 % by weight based on the sum of the hydrocarbons in the hydrocarbon mixture and the use thereof in cosmetic and/or pharmaceutical formulations, and to cosmetic formulations comprising the hydrocarbon mixture.

  • Method for producing aqueous polymer dispersions containing colorants
    Patent number: 7176255
    Abstract: The present invention relates to a process for preparing dye-comprising aqueous polymer dispersions by free-radical aqueous emulsion polymerization of ethylenically unsaturated monomers in the presence of free-radical initiators, in which at least some of the monomers are employed in the form of an oil-in-water emulsion E1 whose disperse phase comprises at least one oil-soluble dye, wherein the disperse phase of E1 is formed essentially of dye-comprising monomer droplets having a diameter<500 nm. The present invention relates in addition to dye-comprising formulations which comprise the dye-comprising polymers of the invention and to pigmented formulations which comprise a polymer of the invention comprising optical brightener.
