  • Green coalescent agent composition containing mixtures of monoesters and diesters
    Patent number: 9926430
    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 %.
