The product is certified?
In the study conducted by the Institute of Hygiene and Tropical Medicine, Universidade Nova de Lisboa. Essay that demonstrates the effectiveness of the product with at least 70 washes, performed according to the standards of the World Health Organization Note that for military purposes there is a slight increase in the concentration which gives an efficiency of no less than 100 washes.
In a second study investigated a sample that has been unused for two years. We managed to prove that there is no loss of active ingredient if the products are still in stock
In a third test: We are doing a study with the Portuguese Army on the following topic: To compare the efficacy of a shirt treated with a solution repellent after 100 washes, compared to a t-shirt untreated. The main objective of this test is to quantify the number of bites or direct contact of mosquitoes in areas covered by t-shirt (unexposed area) and not covered by t-shirt (exposed area).

Is there any problem if a child put the T-shirt ZTop Mosquito Repellent in the mouth?
No. The amounts are negligible. It is harmless.
However, if it is detected an allergic reaction to stop their use.

In case of contact with a wound, may aggravate the same?
There is no evidence.

Have to be washed separately from other clothes?
Advised but not required.

If a person has a t-shirt worn protects the head? What is the radius of action of the product?
Studies already performed with a t-shirt repellent indicate a 100% reduction in bites / contacts within the coverage with respect to a t-shirt not repellent. In the area not covered (head) have a reduction of 91.7% compared to a standard t-shirt.
We have indicated a range that protects the head, and a T-shirt may not be as effective for the hands (arms still protects), since we believe the effective repellent has a radius of about 30cm. We also believe that in the case of the host (data aumentarmos some concentration) being able to have a longer radius.

In climates with humidity and tissues subjected to torrential rain alters the durability of the repellent action?
The repellent action is not changed. The repellent solution will be spending only washes machine. When we speak of washes we refer to machine washes with detergent! If perhaps we use hand washing, surely the repellent effect will stay longer in the tissue. For example, if you make only one pass through soap and water probably keep an efficacy of 150 washes.

It is effective underneath the uniforms? (tshirt)
The active ingredient in textile finishing is a synthetic compound, known as permethrin, similar to natural compounds found in flowers Chrysanthum species.
Permethrin is the only compound accepted in the United States by the EPA (Environmental Protection Agency) for use in clothing and WHO (World Health Organisation) for protection from insect bites.
Permethrin is a pyrethroid active against a wide range of parasites, including lice, ticks, fleas, mites and other arthropods. It acts on nerve cell membrane of the parasite deregulating the sodium channel is regulated through which the polarization of the membrane. The delayed repolarization and paralysis of the parasite are the consequences of its action.
In the case of mosquitoes the solution applied in the finishing of textile works by blocking the pores of the antennae of female mosquitoes preventing them from landing on his victim, even having been stimulated by the presence of CO2.
It follows that contact with skin even be "protected" by a jacket is unlikely. Exposed areas such as the head or hands over the cantilever may be lower.
For more effective protection we recommend an application on all parts, including stockings. The socks are very important because, especially at sunset, the mosquito "attacks" close to the ground.

You can do the treatment on tissue crude?
In the case of uniforms to be an ideal solution due to the existence of other finishes (eg finish waterproof).
As for the t-shirts and socks would be ideal to apply for exhaustion.

The insect repellent can be applied by chemical finish a tenter or laundry.
1. In the tenter, the revenue with chemicals is applied to the foulard by impregnation, passing the squeezing rollers and then follows the drying / heat setting. This type of application because it has more advantages apply the product evenly on the fabric and increases the durability of the same substrate. Used in fabric by the meter.
2. In laundry burnout of the recipe is placed in an industrial washing machine, with a certain amount of H2O, temperature, time, speed, so that the product can penetrate the substrate. Most used articles made.

If the t-shirts have more weight may last longer washes?
In terms of resistance is. As for the repellent there is not much difference because the application takes into account the weight per m²

It is impossible for a t-shirt stand 200 washes?
Yes you have a good weight and washes are not aggressive. Yes!

Side effects? There are people who may be allergic to permethrin?
They are very rare given the concentrations are very low. Note that there are even many permethrin shampoos to eliminate the lice. (in these cases are children and are in contact with the skin)

There are more chances of material composition?
We use these because they are the most common uniforms (jacket / trousers 65% Poly - 35% somewhat). The presence of a synthetic fiber and important because it confers resistance to uniform. Regarding the t-shirts are 100% cotton fibers due to being better for perspiration and the material is suitable for t-shirts. Is also the most economical. The socks can be made in Polyester / Fiber, Cotton / Polyamide
