Sumitomo Chemical pioneered a revolutionary technology to develop a net that effectively prevents mosquito biting, lasts for a long time and resists both washing and tearing. Olyset Net incorporates the insecticide permethrin into the actual fibres of the net, and releases it slowly over a number of years.
Olyset Net passed the rigorous testing procedure known as WHOPES (World Health Organization Pesticide Evaluation Scheme). This involved extensive laboratory and field studies held under scientific scrutiny, and a commitment to quality assurance through the publication of agreed specifications. Olyset Net was the first LLIN to pass WHOPES and earn WHO’s recommendation.
Key features:
- Guaranteed to last at least five years -- research indicates that a seven--year life is often achievable.
- Tough – Olyset Net uses polyethylene technology that makes the net stronger and more tear resistant than polyester nets.
- Controlled release technology – unlike polyester nets, the insecticide in Olyset Net is contained within the fibre, not coated on the outside. This technology provides a slow release of the active ingredient which continues to control mosquitoes for more than five years.
- Quadruple insecticide effect on mosquitoes – bite inhibition, repellency, knockdown, kill. All contribute to protection from biting mosquitoes and other insects.
The paper Development of Olyset Net as a Tool for Malaria Control provides a detailed technical and production history of Olyset.
