The history of mankind is permeated with major concerns about diseases and epidemics. Looking back and around us, it is difficult to define what is worse, the terrifying effect a diseaseon a pandemic scale can cause, or the suffering of the victims it reaches. Much has been done (and still is) to control epidemics – some examples may come to mind such as malaria, H1N1 virus, and swine flu. However, there’s much to be done.
Today, one of the major public health concerns is the transmission of diseases by airborne vectors, such as mosquitoes. In Brazil, despite the long territorial extension, the tropical climate is favorable to the development of these vectors, and everyone knows the ostensive policy that has been adopted to combat mosquitoes that transmit diseases such as dengue fever, chikungunya, Zika virus and even yellow fever – once eradicated from the country.
BESIDES VECTOR CONTROL MEASURES, THE POPULATION HAS SEARCHED MORE WEAPONS
FOR THIS WAR
Every tool to combat the mosquito is welcome. And that is where TNS, in partnership with several industrial sectors, has acted. Through cooperation, the company has been applying nanoencapsulated mosquito repellents in various materials, conferring them this property to increase the safety of consumers in items that are part of their daily life. Do you also want to be part of this process? Then look how!
The secret of TNS repellent is, of course, nanotechnology. Encapsulating these natural repellent agents, such as citronella oil, on a nano scale and transforming it into a more stable and durable product, make its application possible in several matrices. A small dose of the compound is enough to generate a long term repellency. The industrial applications are varied, from industries of polymers and textiles, to paints and varnishes, among others.
THE WELL-BEING FROM THE SECRETS OF NATURE
About the origin of the active principle itself, the citronella (Cymbopogon winterianus) is a plant of the family Poaceae, cultivated in tropical and subtropical regions of America, Africa and Asia. The oil (called "essential oil") extracted from its leaves contains citronellal, geraniol, citronellol and limonene, in addition to other components, which are responsible for the mosquitoes repellent action. Currently, among the products made with natural repellents, those with citronella essential oil are the most used – whether for cosmetic applications or industrially speaking. The actives have a repellent effect against mosquitoes such as Aedes aegypti, Anopheles and Culex.
ALLYING A WIDELY USED NATURAL REPELLENT TO A STATE-OF- THE-ART TECHNOLOGICAL
TREATMENT IS THE KEY
Nanoencapsulation of essential oils increases the active compounds stability, decreasing volatility (compared to pure oil) and prolonging the desired effect. This process of product transformation into its nanoform also ensures greater thermal resistance, allowing the additives processing in industries such as the polymer industries.
In addition, the use of nanocarriers increases aqueous solubility, allowing easy dispersion of the oil into water – as in water based paints. An environment painted with this paint, for example, considerably reduces the mosquito landing area inside a house, forcing it to go away.
In textile applications, due to the reduced particle size, the nanocarriers are able to easily penetrate the spaces between the fibers and attach themselves to the fabric.
The TNS additive was developed for large scale industrial applications and optimized for the best performance when it comes to mosquito repellency. Contact our engineering team to bring this solution to your portfolio.
