GREEN COALESCENT AGENT COMPOSITION CONTAINING MIXTURES OF MONOESTERS AND DIESTERS.

摘要

The present invention relates to the use of mixtures of monoesters and diesters as coalescent agents. The monoesters and diesters according to the present invention are obtained by ethoxylation of fatty acids, and/or by direct esterification of fatty acids with monoethylene glycol or polyethylene glycol. The 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 relates to a composition of coalescent agent comprising: (i) mixtures of monoesters (RCOO(EO)nH) and diesters; and (ii) mixtures of monoesters (RCOO(EO)nH) and diesters obtained by ethoxylation of fatty acids, and/or by direct esterification of fatty acids with ethylene glycol derivatives, and/or by transesterification, the composition containing 90 to 10% by mass monoesters and 10 to 90% by mass diesters.
