Beijing consumer society announced hasten of pure plant mosquito to avoid the agent compares test result this morning. Function that 50 kinds of sample are using initial stage to all do not rise to prevent midge effectively, alleged drive midge is apart from effectively also have no way is mentioned. But the businessman alleges however him product is effective time most be as long as 3 months, allude can bite in order to be far from a mosquito, be suspected of misdirect consumer.
In last few years, allege pure plant kind drive midge is stuck, the mosquito hasten such as hand annulus avoids agent kind the product gains ground gradually in the special group such as pregnant puerpera, infant. But, drive midge is stuck, the mosquito hasten such as annulus of drive midge hand avoids agent kind the product does not have relevant national level or occupation standard, its are multifarious on conduct propaganda, consumer not know what to do. To examine the effect of afore-mentioned products how, beijing consumer society started hasten of pure plant mosquito to avoid the agent compares an experiment.
Sample that experiments quite with the identity of average consumer by staff member of Beijing consumer association inn of the inn of Mu Ying things from Beijing, drugstore, open articles for use is mixed network channel is bought randomly, involve homebred with the part entrance drive midge is stuck, midge of annulus of drive midge hand, drive is buckled etc nominal hasten of pure floral mosquito avoids agent product, altogether 50 kinds of sample, enclothed the brand of common product of midge of pure plant drive on market basically.
Classics test, this second 50 kinds of sample give drive midge ester without check, avoid the pesticide composition such as midge amine. But, there all is an experiment to try bug to try charge after all sample are used, drive midge effect is very poor. Because drive midge effect is poor, drive midge is apart from effectively also have no way is mentioned. Mark of some look forward to set lemongrass aldehyde in product ingredient (a kind of plant extracts content, industry thinks generally to have drive midge effect) chroma, but the sample that this the test contains lemongrass aldehyde is actual drive midge effect is not ideal also.
The test makes clear as a result, hasten of pure plant mosquito avoids agent kind sample uses the effect and its product conduct propaganda actually to not agree with, be suspected of false conduct propaganda, misdirect consumer.
The reporter is in discovery in the sample designation that experiments quite, drive midge pastes kind of product bright shown significant time is in mostly 6 to 24 hours, the longest nominal even 72 hours. The product such as hand annulus bright show time to differ to 3 months from 3 days. Among them, midge of annulus of hand of midge of drive of adjustable silica gel, Bikit drive buckles green source - bear's paw of annulus of hand of midge of oily drive of essence of life of plant of Po benefit, The Green Party, Echain Tech prevents midge to buckle, annulus of hand of midge of only drive of actor of annulus of hand of Bin.Wan drive midge, dimension all alleges its are effective time.
City disappear assist express, product of some drive midge is being packed go up or diction is publicized to have bewitch sex extremely on webpage conduct propaganda, be far from mosquito bite, darling to wait without care for instance, pass a test, all sample all do not rise to defend the action of midge effectively in use initial stage. City disappear assist think its are suspected of exaggerated conduct propaganda, misdirect consumer. And majority sample has bigger taste, suggest consumer discretion is bought.
City disappear assist say, the drive midge product that this kind of pure plant collects content to be raw material did not unite significant evaluation level is the prime cause of disorder of this industry, product. Country of proposal of city disappear association or the standard that occupation standard establishs an orgnaization to be able to make phasing close from the angle that uses actually, normative plant kind the production of drive midge product and sale.
When city disappear cooperates with, express, can need not be opposite the drive midge product of chemical composition is too sensitive, with drive midge amine (DEET) for exemple, if be inside reasonable chroma range, children also can be used. And do not suggest to use the drive midge product that contains citric eucalyptus part under children of 3 years old. To the darling under 6 months, the safest means that prevent midge is midge is patted with mosquito-curtain.
Medical effect determines open pack have mosquito charge
To the comparison of product drug effect the experiment uses yellow-fever mosquito of about 300 female white grain to regard as try bug. From open a product to pack 0.5 hours to rise, every other checks the medical effect of drive midge product 0.5 hours, arrive 2 hours till.
The experiment is unified in 30cm of × of 40cm × 30cm the to sample drug effect in midge basket has a test. Test personnel parts on two the back of hand skin of 40mm of bare 40mm × , cover drops others. The right hand not spray uses any drive midge products, midge of left hand use drive is stuck / annulus of drive midge hand (stick one annulus of ／ ) , fluid of gush drive midge (use quantity makes an appointment with 1.5 microlitre every time every square centimeter) , the midge that extends Cheng Fang to try bug early or late basket, the record stops to fall and try to atttack bare cutaneous mosquito inside 2 minutes several. If midge of the first 0.5 hours of drive is invalid, adjust drive midge effect examines immediately when be being packed to open.
Classics test, all sample are in open pack when checking drive midge effect immediately, all have try bug to try to atttack. Most is there is 6 to try bug to try to atttack only inside 2 minutes. Drive midge product uses effect of drug of the test after 0.5 hours, there also is 5 to try bug to try to atttack only the least inside 2 minutes, most sample has 12 to try bug to have charge only.
The test shows as a result, the drive midge effect that all sample allege is very inaccessible, majority product is suspected of exaggerated conduct propaganda, misdirect consumer.
Drive midge is apart from short of effectively distance of the least test
Use product of midge of pure plant drive actually for imitate, compare the test that the experiment had drive midge is apart from effectively, test method is: Be in center of square box of glass of 1.8m of × of 1.8m × 1.8m, place the small white rat that has bound 1, abdominal equipment wool, by put wormhole to put 20 into yellow-fever mosquito of female white grain, time at the same time. Observe whether small white rat is bitten after 0.5 hours, the record is blank data. Take a sample to be torn open by regular use method go packing, place in the distance on diagonal of square box ground Xiaobai rat is in 0.5 meters, repeat afore-mentioned experimental measure, whether is rat of Xiaobai of the observation after 0.5 hours bitten and record bite amount.
If happen,bite to go to sample distance of small white rat is cut reach 0.25 meters, experiment again, the record bites an amount. If was not bitten, to small white rat sample the distance increases to 1 meter, experiment again, the record bites an amount.
Beijing consumer society can choose 10 sample to have a test, in the distance small white rat is used 0.25 meters hind, all have inside 0.5 hours try bug to have charge, extreme difference of drive midge effect.
