The efficacy of each product was tested by a sample of 35 male and 35 female participants, using subjective and objective (3 referees) methods. Each participant was treated with both a placebo (without the active ingredients) and Trust anti-odorant - new formula. We used A 'double blind-test' method, where both the tested participants and the referees were unaware which sample contained the active material used.

The conclusions were that both the underarm and the foot anti-odorant were highly effective in the elimination of odour for between three and six days, in contrast to the placebo.

Statistically, there was no difference between the positive effect on men and on women.

The participants did not report any adverse side effects from using the product, and most of the users liked the smell, the feel and the convenience of use of the Trust anti-odorant..
