Problems solved by technology

However, formulations containing APE’s do not always provide the most ideal combination of design specifications such as product potency, operating parameters and cost
Traditional non-APE surfactant systems have been difficult to be suitable as substitutes for APE surfactants
For example, calcium dodecylbenzenesulfonate in combination with alkylated amines does not perform as well as APE's and their derivatives because it is not acceptable in one or more of the key performance areas such as: emulsion stability, Acute toxicity, temporal and thermal stability, chemical and physical stability; kinetics of solution, suspension or dilution; shear stress tolerance; viscosity; or lack of compatibility with blend components
[0003] Phosphate esters of alcohol ethoxylates as non-APE surfactants used in many industries due to hydrolysis driven transesterification and saponification involving the monoester, diester and free acid components of the surfactant mixture problem of long-term stability

Embodiment 1

[0029] An oil-based suspension concentrate containing liquid metolachlor as active ingredient was prepared according to the following formulation: 80.0% by weight metolachlor, 3.0% by weight tallow amine (5EO) neutralized triphenylethylene Phenol Ethoxylation

[0030] (8EO) hemisulfate, 3.0% by weight of tristyrylphenol ethoxylate (20EO), 14.0% by weight of aromatic hydrocarbon solvent.

[0031] The above components were formulated as follows:

[0032] Add tallow amine (5EO) neutralized tristyrylphenol ethoxylate (8EO) hemisulfate and tristyrylphenol ethoxylate (20EO) to a vessel containing the aromatic solvent and mix . Then add industrial metolachlor and mix well.

[0033] It should be understood that the surfactants of the present invention are equally acceptable for water-based and oil-based formulations without limitation.

[0034] Another preferred aspect of the invention comprises the combination of the surfactant system of the invention with a solid active ing...

Embodiment 2

[0036] An aqueous suspension concentrate containing solid atrazine as active ingredient was prepared according to the following formulation: 43.5% by weight of atrazine, 2.0% by weight of tridecyl alcohol ethoxylate (6EO) 1.0% by weight of EO-PO Block Copolymer 2.0% by weight tallow amine (8EO) neutralized tristyrylphenol ethoxylation

[0037] (8EO) hemisulfate, 5.0% by weight of ethylene glycol, and make up to 100% with water.

[0038] The above components are processed and formulated as follows: gradually add atrazine industrial products to triphenyl alcohol containing tridecyl alcohol ethoxylate (6EO), EO-PO block copolymer, and tallow fatty amine (8EO). In a container of vinylphenol ethoxylate (8EO) hemisulfate, ethylene glycol and most of the water. The slurry is mixed until homogeneous and then ground to the appropriate particle size. Add remaining water to meet test specifications.

[0039] Another preferred aspect of the present invention includes the combinati...

Embodiment 3

[0041] An aqueous suspension concentrate containing solid atrazine and liquid metolachlor as two active ingredients was prepared according to the following formulation: 26.1% by weight of s-metolachlor 33.7% by weight of atrazine, 1.31% The tristyryl phenol B neutralized by the tristyryl amine (5EO) of tridecyl alcohol (6EO) of 0.4% by weight of oxazam by weight, 0.4% by weight of tridecyl alcohol (6EO) Oxylation

[0042] (8EO) hemisulfate, 1.5% by weight of tristyrylphenol ethoxylate (35EO), 0.7% by weight of defoamers, 0.03% by weight of thickeners such as xanthan gum 0.03% by weight of biological Inhibitor 1.6% by weight ethylene glycol, made up to 100% with water.

Abstract

The present invention relates to a surfactant for general use in agricultural compositions, including, but not limited to herbicidal, fungicidal and insecticidal formulations comprised of two components: an alkoxylated tristyrylphenol acid neutralized to the desired pH or properties with an appropriate amount of alkoxylated alkyl amine.

Description

field of invention [0001] The present invention relates to a surfactant system generally used in agricultural compositions including but not limited to herbicides, fungicides and insecticides comprising the following two components: Alkoxylated tristyrylphenol hemisulfate neutralized to the desired pH with an alkylamine. Background of the invention [0002] Alkylphenol ethoxylates (APE's) and their anionic derivatives are well known surfactants in the industry and pesticide manufacturers have been relying on them. However, formulations containing APE's do not always provide the optimal combination of design specifications, such as product potency, operating parameters and cost. Traditional non-APE surfactant systems have been difficult to be suitable as substitutes for APE surfactants. For example, calcium dodecylbenzenesulfonate in combination with alkylated amines does not perform as well as APE's and their derivatives because it is not acceptable i...
