Description
Technical field
The invention belongs to daily chemical product field, and in particular to a kind of microencapsulation plants essential oil culicifuge.
Background technology
Summer arrives, and the life given people as the mosquito of one of " four pests " brings very big harm.Drone sound is hesitated
Wander in one's ear, disturb one's sleep, and then have influence on new darg, studying and living.If unfortunate by mosquito bite, it will ache
Itch hard to bear, be on tenterhooks.More serious the problem of is that mosquito can propagate malaria, filariasis, Japanese Type-B encephalitis and dengue fever etc.
Disease.
With the development of society, the continuous improvement of human living standard, people also exist to the consciousness of health and self-protection
It is continuously increased, various mosquito repellent products arise at the historic moment in succession.At present, the product of in the market mosquito repellent class is a lot, is concentrated mainly on disc type
Mosquito-repellent incense, the piece that kindles mosquito repellent incense, mosquito-killing spraying agent, floral water, mosquito-dispelling cream, dimethyl carbate, heating mosquito-repellent incense liquid etc..People are the most commonly used in summer
Mosquito repellent articles for use be mosquito-repellent incense, do not know that this can damage to human body but.In fact, the effective ingredient of most of mosquito-repellent incenses is pyrethrin
Insecticide, and organic filler, fusion agent, dyestuff and other additives etc., therefore containing many to people in the cigarette of mosquito incense burning
The harmful material of body, it is possible to induce the diseases such as asthma.According to measuring and calculating, particulate and burn l00 roots or so perfume (or spice) that a roll of mosquito-repellent incense of point is released
The amount of cigarette is roughly the same, the ultrafine dust discharged, can enter and be deposited in lung, may trigger asthma in a short time, for a long time
Cancer may then be triggered.Next to that the carcinogen that mosquito-repellent incense base material imperfect combustion is produced, and some can stimulate and exhale
The compound in road is inhaled, these materials can make the nervous system of people be poisoned.Mosquito-repellent incense, the piece that kindles mosquito repellent incense, mosquito-killing spraying agent, floral water, drive
These mosquito repellent product majorities such as mosquito frost, dimethyl carbate, heating mosquito-repellent incense liquid are to reach repelling effect by agricultural chemicals or chemical analysis, only
It is to play mosquito-repelling function with the harmless composition of Nantural non-toxic to have minority.Therefore, a good, nontoxic, harmless, safety-type mosquito repellent
Product is particularly important in summer.It can not only play good effectiveness, and more importantly the health hazards to human body is seldom, very
To being free from side effects, there is no any pollution simultaneously for environment.
Plants essential oil refers to a kind of volatile flavour for refining and extracting from the flower of plant, leaf, stem, root or fruit
Matter, domestic and international researcher has found that effect of catching up with, and tool are driven, refuse to keep away and smoked to various plants and its essential oil to mosquito with certain
Have and safety educated to people, be not likely to produce the resistance to the action of a drug, it is degradable under natural environment the characteristics of.Much it is made up for this of plants essential oil
Scent mosquito repellent product the sixth of the twelve Earthly Branches is widely used in household bedroom, the occasion such as office, hospital, outdoor.But existing banana mosquito repellent
Product, the problems such as generally existing component is more, cost high and mosquito repellent efficiency is low, fragrance is dull flat weary.Along with some with higher
The most fragrance of folk prescription essential oil of mosquito repellent efficiency is strong, stimulate, and makes us using discomfort, existing essential oil mosquito repellent class product formula does not conform to
Reason, repelling effect, which is difficult to, to be continued, and essential oil product is as liquid form product, and its extremely strong volatility is also to using bringing
Inconvenience, therefore also it is difficult to the requirement that meets consumers in general.
The content of the invention
It is an object of the invention to there is problem and shortage there is provided one kind for above-mentioned with cinnamon oil, wormwood essential oil, fragrant camphor tree
