AI Technical Summary
Enthorone EC and original drugs are prone to decomposition and poor drug efficacy, resulting in unqualified product and unqualified physical and chemical indicators and poor product efficacy when the surfactant is unreasonable.
By adding surfactants such as dodecylbenzene sulfonate, dodecyl polyoxyethylene ether, polystyrene phenol polyoxyethylene ether and ethylene oxide propylene oxide polymer, EC surfactants are formed to ensure that the physical and chemical indicators and efficacy of the preparation products meet the requirements.
The use of special structure surfactants avoids the decomposition of active ingredients, enhances emulsification performance, reduces surface tension, ensures the safety, environmental protection and environmental pollution-free, and improves the efficacy and physical and chemical indicators of the product.

Abstract
Description
Technical Field
[0001] The present invention relates to surfactants, and particularly to clethodim EC surfactants and their applications. Background Art
[0002] It is a well-recognized problem in the industry that clethodim EC and the technical drug are prone to decomposition and poor efficacy; due to its own physical and chemical properties, the clethodim technical drug is prone to decomposition during the processing and production of formulated products, resulting in unqualified products. At the same time, when screening the formulation for preparing the formulation, if the surfactant is not used reasonably, problems such as unqualified physical and chemical indicators and poor product efficacy will also occur. Summary of the Invention
[0003] To solve the above problems, the present invention discloses a clethodim EC surfactant, aiming to ensure that the formulated preparation products meet various requirements through reasonable compatibility with appropriate surfactant products.
[0004] The clethodim EC surfactant includes calcium dodecylbenzenesulfonate, dodecylphenol polyoxyethylene ether, poly(phenylstyryl)phenol polyoxyethylene ether, and ethylene oxide-propylene oxide high molecular block polymer.
[0005] Preferably, by mass, the calcium dodecylbenzenesulfonate is 10-25%, the dodecylphenol polyoxyethylene ether is 15-35%, the poly(phenylstyryl)phenol polyoxyethylene ether is 20-40%, and the ethylene oxide-propylene oxide high molecular block polymer is 15-25%.
[0006] Preferably, the calcium dodecylbenzenesulfonate is 20%.
[0007] Preferably, the dodecylphenol polyoxyethylene ether is 30%.
[0008] Preferably, the poly(phenylstyryl)phenol polyoxyethylene ether is 29%.
[0009] Preferably, the ethylene oxide-propylene oxide high molecular block polymer is 21%.
[0010] Advantages of the present invention;
[0011] 1. Using surfactants with special structures will not cause decomposition of the active ingredients.
[0012] 2. Reasonably compatible with various surfactants to enhance the emulsification performance and reduce the surface tension
[0013] 3. The raw materials used do not contain alkylphenol polyoxyethylene ether, are safe and environmentally friendly, and have no pollution to the environment. Detailed Embodiments
[0014] The present invention will be further illustrated in conjunction with specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.
