An emulsion having a volatile silicone solvent or silicone solvent blend, a primary non-ionic emulsifier substantially free of silicone or a blend of non-ionic emulsifiers substantially free of silicone, and water.

The present invention relates to a process of producing a nano Omega-3 microemulsion system includes: (i) preparing a dispersal phase by heating Omega-3; (ii) preparing a carrier by heating a liquid PEG (polyethylene glycol); (iii) adding the carrier to the dispersal phase; (iv) emulsifying as follows: when the temperature arrives at 60° C., adding ACRYSOL K-140 to the mixture of the carrier and dispersal phase in step (iii), continuing to stir at a speed of 500 to 700 rpm, at a temperature of 60 to 80° C., in vacuum, for 3 to 5 hours, controlling the quality of resulting product by dissolving into water and measuring the transparency, the reaction is quenched, the temperature is decreased slowly until it is in the range of 40 to 60° C.; emulsifying for the entire mixture for 30 minutes; (v) filtrating the product by injecting through nanofilter system before filling-packaging.

The invention relates to a novel sulfobetaine monomer and to a process for the preparation thereof, advantageously by reaction between a vinyl-amine compound and a vinyl-sulfonic acid compound, preferably in the presence of a solubilizing agent. The invention also relates to the (co)polymers obtained from this novel type of sulfobetaine monomer, and to the use thereof, for example as a flocculant, dispersing agent, thickening agent, absorbent agent or friction-reducing agent.

A process for preparing a dispersion comprising the stages: i) providing a dispersion comprising a particulate solid, a liquid medium and a dispersant having cross-linkable groups and a weight averaged molecular weight of from 1,000 to 70,000; and ii) cross-linking the dispersant in the presence of the particulate solid and the liquid medium thereby preparing a dispersion of an encapsulated particulate solid, wherein the cross-linking is performed such that 0.01 to 0.5 mmoles of cross-linkable groups in the dispersant are cross-linked per g of dispersant; said process also comprising at any stage: iii) adding a metal chelating agent to the dispersion; and after stage iii) the stage of: iv) removing at least some of the metal chelating agent from the dispersion.

The invention relates to novel polyglycerol esters with a particular oligomer distribution of the polyglycerol present, and to their use in particular in cosmetic formulations as, for example, emulsifier.

A waste vegetable-oil based emulsifier for use as drilling mud primary emulsifier is described. A first emulsifier is prepared from an alkyl ester of waste vegetable oil. The waste vegetable oil is vegetable oil which has been used for a process prior to preparing the first emulsifier. A quantity of the first emulsifier is added to an oil-based drilling fluid. A quantity of an activating agent is added to the oil-based drilling fluid. The activating agent is configured to activate the emulsifier to stabilize an emulsion. A quantity of viscosifier is added to the oil-based drilling fluid. A quantity of a second emulsifier is added to the oil-based drilling fluid. A quantity of weigh-up material is added to the oil-based drilling fluid. The resulting oil-based drilling fluid is used in a wellbore drilling operation to drill a wellbore in a subterranean zone.

The use of long-chain citric acid esters as additives in aqueous polymer dispersions for production of porous polymer coatings, preferably for production of porous polyurethane coatings, is described.

The use of surfactant formulations comprising long-chain alcohols as additives in aqueous polymer dispersions for production of porous polymer coatings, preferably for production of porous polyurethane coatings, is described.
