Problems solved by technology

However, vegetable oils are not stable in storage, and in US Patent 5,653,911 and US Patent Application 2007 / 0098750A1, it is shown that aerosol products in use on the market use white spirit
However, due to the limitations of volatile organic compounds and maximum ozone-generating activity, as well as cost-benefit considerations, white spirit is not ideal

Embodiment 2

[0057] List several insecticide composition concentrates below, can be made into demulsified water-in-oil aerosol, the formula of this low VOC and MIR insecticide concentrate is as shown in table 2:

[0058] Table 2

[0059] Ingredientswt%

[0060] The insecticide composition concentrate in this embodiment is also a low-VOC and MRI formulation, and also uses methyl soybean fatty acid as a solvent. However, low-lipophilic nonionic surfactants with a water-oil degree (HLB) in the range of 4 to 9 are used, such as sorbitan fatty esters, unsaturated fatty acid alkanolamides, vegetable oil ethyl oxides, and polyglycerol fats. esters. The use of these nonionic surfactants enables insecticide concentrates to be formulated as water-in-oil demulsifying formulations. The addition of plant essential oils not only enhances the activity and pleasant smell, but also has a bactericidal function.

Embodiment 3

[0062] Water-based aerosol can formulations, combined with 0.1% (quick knock down) and 0.1% (long-acting) pyrethroids, respectively, from the insecticide concentrates (F), (G), ( H), (I) are processed by two-stage filling process. The formula of this water-based aerosol can preparation is as shown in table 3:

[0063] table 3

[0064]

[0065] The demulsification process and the method of aerosol can filling are:

[0066] Step 1: Preparation of oil phase and water phase

[0067] A. Mix the concentrated solution of the insecticide composition accounting for 2wt% of the total amount with 12.5wt% isoparaffin oil Isopar M (C13-C14, boiling point about 238 ° C), mix thoroughly, and make an oil phase;

[0068] B, dissolving sodium benzoate-containing preservatives and corrosion inhibitors in deionized water or distilled water to make an aqueous phase;

[0069] The second step: continue to stir the oil phase, and slowly add the water phase to obtain a water-in-oil demulsifier....

Abstract

The invention discloses a concentrated solution for a pesticide composition and an application method thereof. An active ingredient of the concentrated solution for the pesticide composition is pyrethrins or pyrethroid, a solvent is fatty acid methyl ester or fatty acid ethyl ester, and an additive comprises a food-grade or natural antioxidant and an emulsifying agent. The concentrated solution for the pesticide composition can also comprise plant essential oil which is taken as a synergistic agent. The concentrated solution for the pesticide composition has the advantages that the concentrated solution for the pesticide composition is a pesticide composition with quick knockdown and long-acting effect; and the fatty acid methyl ester as the solvent is a low-volatility organic compound and a material with low maximum ozone generation activity, which reduces the harm of a pesticide to human beings and the environment. The concentrated solution for the pesticide composition forms an oil-in-water emulsifying preparation after the dilution to directly serve as a spraying agent for disinsectization application, or forms a water-in-oil demulsifying agent after being mixed with water and odorless gas to serve as an aerosol for disinsectization application. The concentrated solution for the pesticide composition can be used for the control of insect damage of winged insects and reptiles, indoor dust mites, head louses or body louses of human beings and so on, and the anthelminthic treatment of clothes, and can also be used as a sterilizing agent and a fungicide on a target object.

Description

technical field [0001] The invention relates to an insecticide composition concentrate and its application method, which comprises an insecticide active ingredient, a plant essential oil synergist, a biosolvent, an emulsifier and an antioxidant. The insecticide concentrate can be diluted with water to form a stable oil-in-water emulsified spray, or mixed with water and an odorless liquid, and then combined with a hydrocarbon propellant to form a stable water-in-oil demulsified aerosol. For pest control in homes, gardens, businesses and public sanitation. Background technique [0002] Insecticides, the insecticides here generally refer to insecticides, insect growth regulators, fermented biological source insecticides, nicotine insecticides, fungicides, acaricides, bactericides, herbicides, repellents Pesticides, etc., are usually made into various civil and professional products, and are used in households, gardens, pest control and microbial control for humans and animals / ...
