Solubilizing systems for flavors and fragrances, US Patent Application 20060084589 A1

The present invention provides compositions and clear oil-in-water microemulsion containing up to 80% w/w of an oil, a surfactant system, a w/w oil/surfactant system ratio between 1 and 3, and a solubilizing-aid ingredient which is not a surfactant neither a VOC compound, the latter being present in an amount sufficient to ensure that the ratio oil/(surfactant +solubilizing aid) is comprised between 0.1 and 5. The present invention concerns also

VOC-free microemulsions , US Patent Application 20040209795 A1

The present invention provides a VOC-free crystal-clear oil-in-water microemulsion containing up to 30% w/w of an oil, a surfactant svstemn containing a majority of ionic surfactants and a minority of non-ionic surfactants, a w/w oil/surfactant system ratio above 1, up to 10% w/w of a solubilizing-aid ingredient, and at least 60% of water. The present invention concerns also the articles associated with these microemulsions.

Latex particles based on a vinyl acetate ethylene copolymerizate processes for the production thereof and the use thereof , US Patent 6,667,352

The invention relates to protective colloid-stabilized copolymerizate latex particles with a heterogeneous morphology based on a vinyl acetate-ethylene copolymerizate and optionally further monomers, the latex particles having an ethylene content of less than 30 wt. %, based oh the total monomer quantity, comprising an outer phase with a polymer of vinyl acetate and approximately 0 to 40 wt. % ethylene, based on the monomers of the outer phase, and

Transparent high oil loaded microemulsions, US Patent 6,902,756

The present invention relates to the flavor industry. It concerns more particularly a clear, thermodynamically stable and concentrated oil-in-water microemulsion comprising at least 30% by weight of flavor oil, at least two nonionic food grade surfactants forming a "surfactant system" with a defined hydrophilic lipophilic balance, and having an optimized ratio of surfactant versus a co-solvent. The invention also relates to the use of said microemulsion
