Problems solved by technology

[0005] However, the mosquito repellent products disclosed in the above patents are mostly water, alcohol water or pure oil
These mosquito repellent products need to be used in the form of smearing or spraying. The use area is large, the mosquito repelling range is small, and the mosquito repelling time is short. With the passage of time, if the application or spraying is not replenished in time, the concentration of volatile essential oils will gradually decrease. Poor mosquito repellent efficiency
In addition, oil-based products are essential oils that have been diluted with other oils, so they feel greasy when used. Alcohol water-based products are irritating to the skin when used directly.

Abstract

The invention discloses a mosquito repelling gel composition with natural plant essential oil. The mosquito repelling gel composition comprises the following raw materials in percentage by weight: 0.2-5% of water-soluble colloid, 0.2-10% of natural plant essential oil, 0-5% of water-soluble polymers, 1-20% of low alcohols, 0.5-20% of solubilizing agent, 0-0.5% of gel enhancer and the balance of deionized water. The water-soluble colloid in mosquito repelling gel disclosed by the invention can form a reticular or multi-dimensional spiral structure in a water medium and can be stably dispersed or used for wrapping the natural plant essential oil, so that the essential oil is stably and continuously released, and a better mosquito repelling rate can be kept in the whole release process. A mosquito repelling component adopted in the product is purely-natural plant essential oil which is safe to the environment and human bodies; the product is in a gel form; the essential oil is stably volatilized at normal temperature; and when used, the mosquito repelling gel composition does not need to be in direct contact with the skins of human bodies, is convenient to carry and can be continuously used for repelling mosquitoes indoors and outdoors for a long term.

Description

technical field [0001] The invention relates to a mosquito repellent gel prepared by using natural plant essential oils, which belongs to the field of daily chemicals, in particular to a colloidal mosquito repellent product which can be used as indoor and outdoor mosquito repellent. Background technique [0002] The existence of mosquitoes not only affects the work and sleep of human beings, but also is the carrier of various diseases. It has been confirmed that there are more than 60 kinds of diseases that mosquitoes can transmit. At present, the active ingredients of commonly used household insecticides are all pyrethroids. This type of insecticide will cause mosquitoes to develop drug resistance, and the toxicity of this type of insecticide itself also threatens human health. Therefore, many researchers now The focus is on repellants, the use of which prevents mosquitoes from coming into contact with the human body, and mosquitoes will not develop resistance. The commonl...
