1372 results about "Oil emulsion" patented technology

Definition of 'oil-in-water emulsion'. oil-in-water emulsion in the Pharmaceutical Industry. An oil-in-water emulsion is a mixture in which an oily medicine is dispersed in water or other liquid. Small droplets of oil are dispersed in water to create this oil-in-water emulsion.

A thickened oil emulsifying viscosity reducer consists of anion surface activator, non-ionic-anion surface activator, demulsifier and water in proportion by 1:0.1-50:0.01-20 and water content is 0.2-5000 times of the sum of a, b and c. Anion surface activator comprises sodium salt and calcium salt of petroleum sulfoacid salt methyl condensate and sulfonated lignin; non-ionic-anion surface activator is chosen organic phosphate salt, sulfuric ester salt , carboxylate and sulfosalt of alkylphenol or fatty alcohol-polyoxyethylene ether; demulsifier is copolymer of alkyl ammonium halide cation demulsifier, polyethylene glycol polyoxytrimethylene polylol ether non-ionic demulsifier or polyethylene glycol polyoxytrimethylene polyethylene polyamines block. It has strong emulsifying ability and low thickened oil viscosity,

Continuous bulk polymerization and esterification process and compositions

A continuous bulk polymerization and esterification process includes continuously charging into a reaction zone at least one ethylenically unsaturated acid-functional monomer and at least one linear or branched chain alkanol having greater than 11 carbon atoms. The process includes maintaining a flow rate through the reaction zone sufficient to provide an average residence time of less than 60 minutes and maintaining a temperature in the reaction zone sufficient to produce a polymeric product incorporating at least some of the alkanol as an ester of the polymerized ethylenically unsaturated acid-functional monomer. The polymeric product is used in various processes to produce water-based compositions including emulsions and dispersions such as oil emulsions, wax dispersions, pigment dispersions, surfactants and coatings which contain the polymeric product. A polymeric surfactant includes at least one ethylenically unsaturated acid-functional monomer which has been radically incorporated into the polymeric surfactant and at least one ester of the incorporated ethylenically unsaturated acid-functional monomer which has a linear or branched chain alkyl group with greater than 11 carbon atoms. The molar critical micelle concentration of the polymeric surfactant is less than 1.0×10−2 moles / liter. Aqueous 2 percent solutions of certain polymeric surfactants have a surface tension of less than 45 mN / m at 30° C. and exhibit a decrease in surface tension of at least 5 mN / m as the temperature warms from 30° C. to 50° C.

Composition in the form of an oil-in-water emulsion containing cellulose fibrils, and its uses, especially cosmetic uses

The present application relates to a composition in the form of an oil-in-water emulsion comprising an oily phase dispersed in an aqueous phase, characterized in that the composition is free of surfactant and in that it contains cellulose fibrils which have a length of greater than 1 micron and a length / diameter ratio of greater than 30. The invention also relates to the use of the composition, especially for the care, the treatment, the makeup or the cleansing of the skin, lips, eyelashes and / or hair, as well as for the care of sensitive or dry skin.

Novel cosmetic emulsions and emulsifiers exhibiting dilatant rheological properties

InactiveUS20060127344A1Simple structureUnexpected dilatancy propertyCosmetic preparationsHair cosmeticsPolyolDilatant
The use of novel nonionic polymeric thickeners that produce cosmetically useful emulsions of an oil phase and a water phase is described. The thickeners of choice are the urethane dimers of ethoxylated fatty alcohols. These materials were not anticipated to have emulsifying properties. Also, it has been found that the esters of ethoxylated polyols show similar emulsifying behavior, although their uses are limited by their inherent susceptibility towards hydrolysis. Further, many of the emulsions produced with these emulsifiers have a dilatant or shear thickening rheology that is unusual and has unique cosmetic applications. In addition, it is possible to produce high internal phase oil-in-water emulsions, with oil phase concentrations greater than 70%, using these emulsifiers. Finally, many of the emulsions, especially the high internal phase ones, have a characteristic “ring” or vibration that is apparent when their container is tapped. This is a characteristic of so called “microemulsions” that has not been observed in conventional appearing, white (albeit dilatant) emulsions.
