Abstract
A liquid pesticidal composition, which is substantially free of water, comprising a hydrophobic pesticide or mixture of pesticides dissolved in an organic solvent and comprising as surfactants (a) a castor oil ethoxylate having 30-50 mol ethoxylate, (b) a branched C8-C18 alcohol ethoxylate having 5-10 mol ethoxylate, and (c) a tristyrenephenol-ethoxylate having 8-30 mol ethoxylate, or its phosphate or salt thereof. The compositions also include gels having a viscosity of 500 to 20,000 mPas and comprising additionally a gelling agent.
Claims40
A liquid pesticidal composition comprising a hydrophobic pesticide or mixture of pesticides dissolved in an organic solvent and comprising as surfactants
- (a) a castor oil ethoxylate having 30-50 mol ethoxylate
- (b) a branched C8-C18 alcohol ethoxylate having 5-10 mol ethoxylate, and
- (c) a tristyrenephenol-ethoxylate having 8-30 mol ethoxylate, or its phosphate or salt thereof
- said composition being substantially free of water, wherein said organic solvent is selected from the group consisting of a water-miscible solvent, a water-immiscible solvent, and mixtures thereof, wherein said water-immisible solvent is selected from aliphatic and aromatic hydrocarbons, halogenated hydrocarbons, phthalates, ethers and esters, fatty acid esters, lactones, ketones, plant oils, methyl esters of said plant oils, epoxidized coconut oil, epoxidized soybean oil and mixtures thereof;
- and wherein said water-miscible solvent is selected from the group consisting of alcohols, glycols, N-methyl-2-pyrrolidone, tetramethylurea, gamma-butyrolactone, dimethylsulfoxide, N,N-dimethylacetamide, N,N-dimethylformamide, and mixtures thereof;
- whereby said composition is capable of being stably stored for a period of at least one year at 25° C.
A liquid pesticidal composition comprising a hydrophobic pesticide or mixture of pesticides dissolved in an organic solvent and comprising a mixture of surfactants consisting essentially of
- (a) a castor oil ethoxylate having 30-50 mol ethoxylate;
- (b) a branched C8-C18 alcohol ethoxylate having 5-10 mol ethoxylate;
- (c) a tristyrenephenol-ethoxylate having 8-30 mol ethoxylate, or its phosphate or salt thereof, and
- (d) optionally an alkylbenzenesulfonate or a salt thereof;
- said composition being substantially free of water, whereby said composition is capable of being stably stored for a period of at least one year at 25° C.
