Head Lice Treatment
Each year, 6-12 million head lice
infestations occur among U.S. children
aged 3-11. As early as 1999, research
showed that lice in the U.S. were
becoming resistant to permethrin1,an
active ingredient that is part of the
pyrethroid chemical family and
is commonly found in head lice
treatments. A study published in
2003 confirmed a genetic mutation
that caused complete resistance to
permethrin.2
We are making great progress in the
development of a natural head lice
solution that kills pyrethroid-resistant
strains of head lice and their nits with the highest levels of personal safety. Our natural
formulations are showing superior efficacy as compared to leading synthetic products
currently in the marketplace.
Personal Repellent
The Centers for Disease Control (CDC) receives
more than 20,000 reports of Lyme disease
(transmitted by deer ticks) and 100 reports
of encephalitis (transmitted by mosquitoes)
annually. Both of these diseases can cause
serious health problems or even death in the
case of encephalitis. Where these diseases are
endemic, the CDC recommends use of insect
repellents when out-of-doors.
We are leveraging our repellency technology to
develop a range of personal repellent solutions
to control mosquitoes, ticks and other pests
that can carry infectious diseases such as West
Nile virus and Lyme disease. Our testing against
yellow fever mosquitoes indicates performance
superior to 7%-15% DEET formulations currently
available in the marketplace.
Functional Foods
TyraTech and Kraft are developing an innovative functional
food solution to combat global intestinal parasitic infestation.
Studies have shown that the TyraTech-Kraft technology kills
worms in vitro and decreases the number of worms and their eggs in vivo.
