Citrefine’s Citriodiol® Oil of Lemon Eucalyptus insect repellent has been approved by the U.S. Environmental Protection Agency (EPA) for use against deer ticks, following a study conducted by ARCTEC at the London School of Hygiene & Tropical Medicine.
The 3-species tick study, led by the ARCTEC team, produced results to show Citriodiol® OLE insect repellent provides 100% protection against deer ticks for an average of 290 minutes (almost 5 hours).
When tested against the brown dog tick and lone star tick, Citriodiol® OLE provided more than 8 and 10 hours of complete protection respectively. 25 human volunteers were tested in total for each species of tick (75 replicates in total) during the study.
The results from the study were submitted to the EPA by ARCTEC and Citrefine, and the US authority has given its approval for the product label to claim 4 hours protection against deer ticks. This will allow Citrefine to add label claims to its product and inform consumers of the repellency of Oil of Lemon Eucalyptus products towards these tick species.
Professor James Logan, Director of ARCTEC and Head of the Department of Disease Control at the London School of Hygiene & Tropical Medicine, said: “We are delighted that Citrefine’s Citriodiol ® OLE insect repellent has been given approval by the EPA for use against deer ticks following this study conducted by ARCTEC. With the extensive expertise and experience held by our research team, we produced high-quality, accurate test data approved by the EPA.”
Genevieve Faherty, Regulatory Affairs Director at Citrefine, said: “Gaining HSRB and EPA approval for repellency studies is a difficult job involving numerous regulatory challenges. I am extremely pleased that ARCTEC was able to oversee this project so efficiently allowing consumers to have confidence in the rigour of the repellent testing underlying our Citriodiol® products.”
