How it works.

Rather than harsh chemical pesticides, Fend® uses an active ingredient called IR3535® (ethyl butylacetylaminopropionate), a gentle amino acid derivative.

It works by confusing insects' sensory receptors, disrupting their ability to detect carbon dioxide and therefore their ability to find and bite their host.

IR3535® is considered a safer and more environmentally friendly alternative to DEET.

Dermal Irritability

OBJECTIVE: To evaluate the potential of adverse skin reactions caused by topical use.

PARTICIPANTS: 54 participants - 43 women, 11 men - aged 19-63.

METHODOLOGY: The repellent was applied to hypoallergenic adhesive strips. Strips were applies to the same location on participants 3 times per week for 3 weeks.

RESULTS: No side effects (erythema, edema, papule or vesicle) were detected in the area of application, and no participants reported sensations of discomfort during the study.

CONCLUSION: A primary irritation index of 0.0 out of a possible 8.0 at is sufficient to classify the repellent as 'Toxicity Category IV - Very Low Toxicity'.

Photosensitisation

OBJECTIVE: To evaluate the potential of adverse skin reactions caused by exposure to UV light following topical use.

PARTICIPANTS: 35 participants - 28 women, 7 men - aged 18-63.

METHODOLOGY: The repellent was applied to hypoallergenic adhesive strips. Strips were applied to participants for 24 hours. When removed, the test area was immediately exposed to 4 J/cm2 UVA light to test for discomfort or clinical reactions. Tests were repeated on the same area 3 times per week for 2 weeks.

RESULTS: No side effects (erythema, edema, papule or vesicle) were detected in the area of application.

CONCLUSION: The product did not cause photosensitisation and was not shown to be phototoxic and support the 'hypoallergenic' appeal.
