A stable matrix emulsion concentrate of a biocide, e.g. 3-iodopropynyl-2-butyl carbamate (IPBC) and/or a triazole fungicide, and stable aqueous and/or organic solvent formulations thereof, i.e. dilutable in water and/or an organic solvent are provided, which are particularly useful for treating wood products to provide protection against microorganisms and insects.
摘要:
What is described herein is a synergistic matrix composite for making a stable microemulsion in water of an active ingredient comprising a first matrix composition including by wt. (a) 5-30% of a C8-C18 N-alkyl pyrrolidone, (b) optionally, 5-60% of a water insoluble organic solvent soluble therein, (c) 30-70% of a non-ionic emulsifier, and (d) 1-15% of an EO/PO/EO copolymer, and, (e) optionally, 1-5% of a surface active buffering agent, e.g. a branched alkyl ethoxylated phosphate ester, a second matrix composition comprising a polar polymeric material, e.g. polyethylene glycol, and/or a neutralized derivatized vegetable oil, e.g. maleated linseed oil, which composite is capable of loading a higher amount of said active than either composition alone.

Polymers are provided that are derived from at least (A) N-vinyl formamide, (B) one vinyl amide moiety or one acrylamide moiety, and (C) a reaction solvent. The polymers are random, block, or alternating polymers. A particular useful poly-mer comprises about 20% N-vinyl formamide, about 50% N-vinyl-ε-caprolactam, about 30% N-vinyl-2-pyrrolidone, being synthesized in ethylene glycol. In preferred embodiments, polymers of the invention exhibit a cloud point temperature of 66° C. or more, inhibit the formation of gas hydrates, and/or inhibit corrosion. Especially preferred uses of the polymers are in oilfield operations as gas hydrate inhibitors and/or corrosion inhibitors.
摘要:
A stable wetting concentrate includes octyl or dodecyl pyrrolidone, an ethoxylated alcohol, and a compatabilizing agent for dilution of the concentrate with water, suitably a polar material, such as an anionic emulsifier, or polyol, which prevents separation of the two base components in water, and, optionally, water, provides a stable wetting composition upon dilution with water, which exhibit superior wetting and spreading properties.
摘要:
A composition comprising a long-chain alkylpyrrolidone, a surfactant, and film-forming water-soluble polymer wherein the amounts of the components are such that on dilution with water, a clear liquid is formed. The composition may be used as a medium for agriculturally active ingredients as well as other active ingredients which are suitable for film formation, e.g., wood protectants, and the like.
摘要:
The present invention relates to the stabilization of an agricultural chemical concentrate in aqueous solution and the stabilized concentrate which comprises: (a) between about 0.1 and about 20 wt. % of a stabilizer composition comprising: (1) between about 10 and about 90 wt. % of a water-insoluble, non-crosslinked, film forming polymer, and (2) a polymer solubilizing amount of an aromatic petroleum distillate or an oxygen-containing solvent of an N-alkyl pyrrolidone, a C.sub.3 to C.sub.8 alkanol, a dibasic acid lower alkyl ester, an ether having a boiling point above 150.degree. C. or mixtures thereof and (b) between about 80 and about 99.9 wt. % concentrate containing a water-insoluble active agricultural chemical, a solvent for said agricultural chemical and a surfactant for said concentrate. The invention also relates to the use of said stabilized concentrate.
摘要:
This invention relates to a 1-8% crosslinked terpolymer of a C.sub.1 -C.sub.4 alkyl vinyl ether, maleic anhydride and a hydrophobic C.sub.6 to C.sub.18 alkyl vinyl ether in a critical molar ratio of from 1-3:1:0.01-0.20, which polymer has a pH of from about 4 to about 11, a Brookfield viscosity of from about 10,000 to about 150,000 cps and is characterized as having desirable salt tolerance enhanced viscosity, stability, low residual monomers and enhanced use characteristics. The invention also relates to liquid or aqueous gel compositions of the crosslinked terpolymer containing a salt and a method for the preparation of said crosslinked terpolymer gel.
摘要:
A three part cleaning composition uses C.sub.6 -C.sub.20 alkyl substituted lactam as a cleaning agent, an anionic surfactant and water to solubilize and remove oil or grease from hard surfaces. The lactam is provided in a ratio, relative to surfactant of 5-0.1 to 5-3.0, more preferably 5-0.1 to 5-1.0. The composition is surprisingly effective in forming micro-emulsions with the oil or grease and maintaining the emulsions for ease in disposal. Using an aqueous solution including C.sub.6 -C.sub.20 alkyl substituted lactam provides a low volatility, non-flammable degreasing solution, which is highly effective and biodegradable.
摘要:
A water based wetting agent uses higher alkyl substituted lactam, anionic surfactant and water to enhance the wetting properties of herbicide and pesticide formulations. The composition is effective in enhancing wetting times, and in some instances increases the formulation effectiveness through enhanced contact, better penetration and lower surface tension. Utilizing a herbicide or pesticide formulation including the wetting agent provides a fast absorption of actives with rapid uptake to promote weed control with no or minimal phytotoxicity at the use levels.
