Abstract
A liquid agricultural adjuvant including at least one alkyl (C1-C8) ester of an alkyl (C12-C16) acid; at least one anionic surfactant; and at least one nonionic surfactant. The liquid agricultural adjuvant has a flash point higher than about 100° C.; and the at least one alkyl (C1-C8) esters of alkyl (C12-C16) acid has a paraffinic wax dissolution capability of between 2 wt. % to 20 wt. % at 25° C. A method of manufacturing and using the liquid agricultural adjuvant is also included.
Claims7
A liquid agricultural adjuvant, consisting of:
- from 0.1 wt. % to 20 wt. % of at least one alkyl (C1-C8) ester of an alkyl (C12-C16) acid, wherein the at least one alkyl (C1-C8) ester of an alkyl (C12-C16) acid is selected from the group consisting of isobutyl laurate, isopentyl laurate, isopropyl laurate, isopropyl myristate, and combinations thereof;
- from 1 wt. % to 50 wt. % of at least one anionic surfactant, wherein the at least one anionic surfactant is selected from the group consisting of:
- (C6-C18) alkyl benzene sulfonic acid salts, calcium dodecylbenzene sulfonate, sodium dodecylbenzene sulfonate, amine (C6-C18) alkyl benzene sulfonate, triethanolamine dodecylbenzene sulfonates, (C6-C18) alkyl ether sulfates, (C6-C18) alkyl ethoxylated ether sulfates, (C6-C18) alkyl sulfates, lauryl ether polyethoxylated sodium sulfate, (C6-C8) alkyl phosphate esters, (C6-C18) alkoxylated sulfates, (C6-C18) alkoxylated phosphate esters, xylene sulfonate salts, cumene sulfonate salts and combinations thereof;
- from 1 wt. % to 50 wt. % of an at least one nonionic surfactant, wherein the at least one nonionic surfactant is selected from the group consisting of:
- (C8-C22) alkoxylated fatty alcohols, (C8-C22) ethoxylated fatty alcohols, (C8-C22) propoxylated fatty alcohols, (C8-C22) ethoxylated and propoxylated fatty alcohols, straight chain (C4-C10) alkyl(poly)glycosides, branched chain (C4-C10) alkyl(poly)glycosides;
- and alkoxylated sorbitan fatty esters, alkoxylated sorbitol fatty esters, ethoxylated sorbitan fatty esters, ethoxylated sorbitol fatty esters, polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan monopalmitate, polyoxyethylene sorbitan monostearate, and combinations thereof;
- and
- from 2 wt. % to 80 wt. % of water and additives selected from the group consisting of preservatives, clarifiers, anti-freezing agents, hydrotropes, stabilizers, antioxidants, dyes, rheology modifiers, antifoams, anti-drift and water, oil or other solvents, and combinations thereof;
- wherein the liquid agricultural adjuvant has a flash point higher than about 100° C.;
- and
- wherein the at least one alkyl (C1-C8) esters of alkyl (C12-C16) acid has a paraffinic wax dissolution capability of between 2 to 20 wt. % at 25° C.
