Abstract
The present invention provides a water-soluble composition including lysophosphatidylethanolamine, an organic solvent, a silane-based auxiliary agent, a surfactant, an antifreeze, and water. According to the water-soluble composition of the present invention, a lysophosphatidylethanolamine effective ingredient is not decomposed well even at a high temperature, and since the composition is stably dissolved in water when diluted in water before applied to crops, the stability of a water-soluble formulation is excellent. In addition, since surface tension is excellent, the composition may be uniformly distributed when treating fruits to show uniform ripening promoting effects of the fruits.
