Oil formulations with thickeners

摘要

This invention is based on unexpected effect of at least one thickener to maintain suspension or dispersion of solid particles in an oil medium. Such effect of thickener enables significant higher weight ratio of solid particles in such suspension composition as compared to previously known compositions. As a consequence, the suspension compositions provided herein enable more active ingredient in the solid particle to be present in a fixed volume or weight of such composition as compared to previously known compositions. One advantage of the suspension composition provided herein can be for aerial spraying of active ingredient such as herbicides, insecticides, or other growth regulating compounds.

主权项

1. A composition comprising solid particles of a cyclopropene complex comprising a cyclopropene molecule encapsulated in a molecular encapsulating agent, characterized in that said composition additionally comprises an oil medium, that said solid particles are stably suspended in said oil medium, and that said solid particles have a median size, as measured by the largest dimension, of 50 micrometer or less;
wherein said oil medium comprises one or more dispersants; wherein said molecular encapsulating agent is alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin, or a mixture thereof; and wherein said cyclopropene molecule has a structure of formula where each of R1, R2, R3, and R4 is hydrogen or (C1-C4) alkyl.
