A water-in-oil emulsion ink comprises a water phase and an oil phase, wherein the water phase comprises a carbon black pigment having a pH of less than 6. The emulsion ink maintains stable rheology on ageing.

An oil-in-water type emulsion cosmetic which contains (A) a hydrophilic surface active agent, (B) an oily component and (C) water, and weight ratio of the component (B) is 10 or more based on 1 of the component (A).

An emulsion explosive including a discontinuous phase dispersed in a liquid fuel continuous phase and is provided. The discontinuous phase contains a liquid oxidizer other than an inorganic oxidizer salt. Also provided are articles of manufacture containing the emulsion explosive.

An emulsion polymer and a method for preparing the emulsion polymer by the free radical polymerization of at least one first ethylenically unsaturated monomer to form a first emulsion polymer and the subsequent treatment of the first emulsion polymer with a colloidal stabilizer, at least one second ethylenically unsaturated monomer, and a redox system at 20-85.degree. C. is provided.

The invention concerns an oil-in-water immunostimulant emulsion comprising an aqueous phase and an oil phase, characterised in that it further comprises an immunostimulant polynucleotide whereof at least part is covalently bound to at least a lipid molecule. The invention also concerns a vaccine composition comprising such an emulsion as immunoadjuvant.

An emulsion ink comprises a continuous oil phase, two or more dispersed liquid phases, one of which is a dispersed oil phase, and a solid material dispersed in the dispersed oil phase. The emulsion ink is suitable for use on a stencil or digital duplicator, and has improved rheological properties.

Breaking emulsion forming at the interface in a relatively immiscible liquid-liquid contacting process by withdrawing it, adding one component thereof in an amount sufficient to shift the composition to the one-phase region of the solubility diagram, then collecting the product obtained.

The defoaming activity of an aqueous defoaming emulsion containing an emulsifier, silica in fine particle form and methylpolysiloxanes is increased by incorporating into the emulsion 10 to 60 percent by weight, calculated on the total amount of siloxane in the emulsion, of organosilicon compounds of the general formula: wherein X stands for -OR, R being hydrogen or alkyl of one to four carbon atoms, n has a value of 1.8 to 2.0 and m has a value from 0.02 to 0.33.

An emulsifier comprising at least one ester of a polyhydric composition and a mono-or poly-basic organic acid, the polyhydric composition preferably comprising a sorbitol and/or sorbitan derivative and the acid PIBSA.

An emulsion comprising:(A) a discontinuous phase; (B) a continuous organic phase; and (C) an emulsifying amount of at least one nitrogen and transition metal containing composition derived from hydrocarbon substituted polycarboxylic acids or functional equivalent thereof, selected from the group consisting of (C-1) amide and imide derivatives of transition metal salts, (C-2) transition metal complexes of non-acidic acylated nitrogen compounds, and (C-3) a mixture of acylated nitrogen compounds a...
