Silab conducted two separate studies related to the development of Deolya. The first focused on Staphylococcus hominis. The company developed a modeling study that demonstrated quantitative (increased abundance) and qualitative modifications (increased enzymatic activity) of S. hominis strains sampled from the axillary microbiota of malodorous volunteers subjected to physical activity, compared to a non-odorous panel.
In response, Deolya limits the excessive abundance of S. hominis in the axillary cutaneous microbiota and targets the enzymatic activity of this bacterial species.
The second study was a panel that involved caucasians of both sexes participating in a physical activity wherein Deoyla reduced perspiration odors by 58% as of the first application, per the company. This deodorant efficacy, assessed by an olfactory evaluation from an expert panel qualified in sensorial measurement, is confirmed at the molecular level by a 76.3% reduction of the malodorous 3M3SH thiol. These effects are also observed after seven days of daily use and without having applied the deodorant in the morning before the physical activity session.
