An evaporation retardant composition engineered for wide applicability to co-delivery of non-filmforming chemicals, along with filmformers, wherein the former are as beneficial to plant cultivation and/or animal husbandry in their own uses, as are fatty alcohol filmformers by saving water. A previously disclosed concept of water-induced ionization that causes mutual particles' repulsion to enhance spreading is freshly embodied with use of a dicarboxylic acid, preferably oxalic acid, as the ionic repulsion agent. Avoidance of esterification between the included alcohol and acid infiltration into soil, which is a problem known to limit usefulness of emulsified fllmforming compositions is disclosed.
一种蒸发延缓剂组合物,可广泛应用于非成膜化学品与成膜剂的共同施用,其中前者与脂肪醇成膜剂一样,通过节约用水对植物栽培和/或畜牧业本身的用途有益。之前公开的水诱导电离概念可使颗粒相互排斥,从而增强铺展效果,这种概念在使用二羧酸(最好是草酸)作为离子排斥剂时得到了新的体现。本发明还避免了醇和酸之间的酯化作用以及酸对土壤的渗透作用,众所周知,酯化作用会限制乳化成膜组合物的用途。
