Abstract

An object of this invention is to provide a spreader composition having excellent rain resistance and water dispersibility and being mild and friendly to the environment and a human body. This invention relates to a spreader composition containing a surfactant (A) and a polyoxyethylene hardened castor oil (B), wherein the surfactant (A) has a surfactant having a melting point of 40 DEG C or more and a HLB of not more than 8.

Description

Spreading agent composition Field of invention

The present invention is directed to a spreader composition.

Background of the invention

The surface of the leaves, stems and insects of plants has a composition or structure that can repel liquids. Therefore, the spread of the pesticide cannot adhere to the above-mentioned skin surface, and there is a case where sufficient effect cannot be exhibited.

Therefore, in the prior art, a spreading agent is blended in the agricultural chemical to enhance the moisturizing, soaking, and fixing properties of the agricultural chemical to increase the drug efficiency (Non-Patent Document 1).

Heretofore, nonionic surfactants such as polyoxyethylene ethyl ether, sorbitan fatty acid ester, polyoxyethylene alkyl ether, polyether modified siloxane have been used (Patent Documents 1 and 2), and alkane An anionic surfactant such as an alkali metal sulfosuccinate or an alkali metal salt of a naphthylsulfonate (Patent Document 3) is used as a proppant for agricultural chemicals.

However, when these spreading agents are used, although the properties such as the wettability of the liquid are improved, there is a problem that the pesticide component in the spray liquid sprayed on the object is inferior in rain resistance.

Moreover, the spreader composition described in Patent Document 2 is used. The alcohol solvent has an adverse effect on the environment or the human body, and even has a problem of poor dispersion of water.

Therefore, it is expected to be an exhibiting agent which has excellent rain resistance and water dispersibility and is environmentally friendly and human friendly.
