Hansk Anti-Insect Technology
Permethrin is an insecticide in the pyrethroid family. Pyrethroids are synthetic chemicals that act like natural extracts from the chrysanthemum flower, which can repel and knock-down the majority of insects.
The insecticidal effect is based on its ability to be absorbed into the body by insects and cling to the sodium ducts of nerve cells, interfering with nerve signal transmission, leading to paralysis and death. Permethrin is highly toxic to insects, therefore they have developed mechanisms to avoid contacting permethrin, so that permethrin-containing products have repelling effect. In addition, because permethrin can be metabolized naturally by human body, therefore the toxicity is low on human health.
The U.S. military have been using permethrin on their uniforms for more than 30 years. Permethrin is now commonly used as an active ingredient in insect repellent clothing. Hansk can significantly enhances the repellency and washability of permethrin, this allow a range of safe, effective and durable products to be developed.
BACKGROUND
According to a survey conducted by the World Health Organization (WHO), mosquitoes are the deadliest animal in the world, they cause more human suffering than any other organism. And some mosquitoes are vectors for diseases. Each year, over 1million people die from mosquito–borne diseases worldwide. In Africa, one child dies of malaria every minute. The number of dengue fever has also increased 30 times in the past 50 years. Up to 40% of the world’s population is at risk of dengue fever.
In 1999, St. George’s College of Medicine, University of London published a scientific literature stating an average bed has at least 15 million dustmites and they have a reproduction rate 10 times of rats! The number of dustmite will double in every 3 days, and will cause skin irritation, as well as asthma and other allergies.
REPEL & KNOCKDOWN
Repel: when insects approaching the treated articles, they are repelled as they sensor threats.
Knockdown: when insects make contact with the treated articles, Permethrin adhere to the sodium channels in their nerve cells, thereby interfering with the transmission of nerve signals, leading to paralysis and knockdown.
KEY BENEFITS
- Dual Functions – Repel & Knockdown: Permethrin is a contact insecticide. Hansk can significantly enhance the repellency to achieve repel and knockdown dual functions.
- Long-Lasting: Permethrin has low volatility and does not rely on odour release to repel insects, therefore treated articles has long-lasting anti-insect property. Hansk can enhance the washability of treated fabric and remain effective after 30-50 washes.
- Wide Range of Application: Hansk products can be used on most home substrates including textile, wall, wood, plastic, stainless steel, etc.
- Safe, low toxicity, non-irritating
- Does not affect the hand-feel and color of the treated articles
