Abstract

The invention discloses a water-based insect expelling aerosol composition which comprises the following components in percentage by weight: 0.2%-20% of insect expelling active component, 0.01%-5% of phosphate surface active agent, 0.003%-5.5% of pH regulating agent, 5%-60% of ethanol, 30%-80% of deionized water and 5%-30% of propelling agent, wherein the phosphate surface active agent is phosphomonoester or phosphodiester or a mixture of the phosphomonoester and the phosphodiester, and the phosphomonoester or the phosphodiester or the mixture of the phosphomonoester and the phosphodiester is in a chemical structure which contains more than 12 carbon atoms; the pH range of the water-based insect expelling aerosol composition is 6-8. The water-based insect expelling aerosol composition disclosed by the invention can effectively prevent the mosquito bite. According to the water-based insect expelling aerosol composition, the pH value of an aerosol content system is neutral, so that the degradation of active component and the corrosion to a tank body can be well prevented.

Description

technical field [0001] The invention belongs to the technical field of insect-repelling aerosol products, and in particular relates to a water-based insect-repelling aerosol composition with insect-repelling activity and a method for preventing corrosion of a water-based insect-repelling aerosol container. Background technique [0002] Insect repellent aerosol products include insecticide aerosol and skin repellent aerosol. In the insecticidal aerosol products, the current formula is still oil-based, and most of them use alkane solvents to dissolve the insecticidal active ingredients. The cost of this type of aerosol products is high, and the solvent oil used is mostly non-renewable resources. Flammable and explosive, poor safety, and the content of volatile organic compounds (VOC) in this type of oil-based aerosol is high, and it is very irritating and polluting when used in the home environment, which is not environmentally friendly. Water-based insecticide aerosol has ma...
