Abstract: The present invention is directed to compositions of green coalescents comprising monoesters obtained from direct or indirect esterification of vegetable oil fatty acids and fusel oil alcohols. The fatty acids used in the present invention have 6 to 22 carbon atoms and can be either saturated or unsaturated.

Abstract: The present invention relates to the use of mixtures of monoesters and diesters as coalescing agents. Monoesters and diesters according to the present invention were obtained by ethoxylation of fatty acids, and/or by direct esterification of fatty acids with monoethylene glycol or polyethylene glycol. Fatty acids used in the present invention have 4 to 22 carbon atoms and can be saturated or unsaturated, linear or branched. In particular, the invention is directed to a composition of coalescing agents comprising: (i) mixtures of (RCOO(EO)nH) monoesters and diesters; and, (ii) mixtures of (RCOO(EO)nH) monoesters and diesters obtained from the ethoxylation of fatty acids, and/or direct esterification of fatty acids with ethylene glycol derivatives, and/or transesterification, wherein the monoesters are present in an amount of 90 to 10 mass % and diesters are present in an amount of 10 to 90 mass %.

Abstract: The present invention relates to aqueous resin emulsions containing at least a non-ionic surfactant of general formula R1-(A1O)n-(A2O)x-(A3O)y—R2, obtained by the phase inversion emulsification process. In particular, the invention relates to aqueous resin emulsions commonly used in solvent-based paints, such as, for example, alkyd resins. Said emulsions are stabilized by non-ionic and anionic surfactant compositions which promote the inversion of the water-oil to oil-water phases in the presence of low water content, enabling water-oil type emulsions to be obtained with high productivity and high solids content, even in low shear conditions.

Abstract: The deposition of organic materials originating from crude oil, such as asphaltenes and paraffins, is deemed to compromise satisfactory oil exploration and production, because it clogs pores and equipment, compromising the operation performance. This problem may arise at various points during the operations of drilling, stimulating, fracturing, completing and cementing wells, production, transportation, refining and storage of oil and derivatives, including the use of the fluid in treatments for oil wells and reservoirs, well tubing and annuli, tubing, equipment, and tanks used in treatment processes, transportation and refining of oil and derivatives thereof. The present invention relates to a solvent composition to solubilize such deposits and incrustations.
