  • Publication number: 20090005463
    Abstract: Solubilizers are described which comprise a) one or more ethoxylated fatty alcohols according to formula (I) in which R1 is a linear or branched alkyl radical having 6 to 12 carbon atoms and n is on average a number from 2 to 12, b) one or more ethoxylated triglycerides whose acyl radicals are derived from linear or branched saturated fatty acids having 6 to 22 carbon atoms, and c) water and which are liquid and clear at room temperature and do not comprise addition products of ethylene oxide and simultaneously propylene oxide onto fatty alcohols. The solubilizers are suitable in particular for producing cosmetic, dermatological or pharmaceutical formulations.

  • Patent number: 6586479
    Abstract: The invention relates to fine emulsions comprising at least one W/O emulsifier and at least one hydrophilic component, and to a process for their preparation. The fine emulsions are obtainable by converting a W/O preemulsion comprising at least one W/O emulsifier into an O/W fine emulsion by adding at least one hydrophilic component and, where appropriate, changing the temperature. Suitable W/O emulsifiers are preferably sorbitol esters. The fine emulsions are preferably spray emulsions for cosmetic and pharmaceutical applications.
