Silab combines hygiene and skin care in deodorants with a meadowsweet extract


For their new development, Silab sought to combine the effectiveness expected by consumers of deodorants against malodors, with the growing quest for products of natural origin that are respectful of the skin.

Targeting odor causing bacteria

In order to better address the mechanism leading to the generation of odors, Silab developed an original modeling study that demonstrated quantitative (increased abundance) and qualitative modifications (increased enzymatic activity) of Staphylococcus hominis strains sampled from the axillary microbiota of malodorous volunteers subjected to physical activity, compared to a non-odorous panel.

In response to this problem, Silab has shown that their new ingredient limits the excessive abundance of S. hominis in the axillary cutaneous microbiota and targets the enzymatic activity of this bacterial species. Deolya thus targets the source of perspiration odors while leaving the microbial diversity of this skin zone unaffected.

Double performance against odors

The effectiveness of Deolya against odors was tested on a Caucasian panel of both sexes participating in a physical activity. The study showed a reduction of perspiration odors by 58% as of the first application of the product containing the active ingredient.

This deodorant efficacy, assessed by an olfactory evaluation from a qualified expert panel, is confirmed at the molecular level by a significant 76.3% reduction of the malodorous 3M3SH thiol. According to Silab, these effects are also observed after seven days of daily use and without having applied the deodorant Deolya in the morning before the physical activity session, underlining the immediate and long-term effect of the deodorant.

Reduction of axillary irritation

In addition, according to Silab, Deolya reduces inflammation, thus significantly decreasing the frequency of unpleasant underarm sensations appearance, daily but also after shaving or epilation (after 28 days of use). In particular, the active ingredient strengthens the barrier function, resulting in vivo in an improvement of Transepidermal water loss (TEWL) of underarm skin.

Thanks to this multifunctional benefits, Deolya is a natural deodorant solution providing comfort and soothing to the axillary zone.

A French, organic-certified supply

For this development, Silab research beneficially used the tellimagrandin-type ellagitannins and proanthocyanidols found in meadowsweet, giving Deolya its unique polyphenolic profile. Obtained from French suppliers certified for organic agriculture and traced back to the harvest site, this raw material complies with Silab’s criteria for traceability and sustainability.

Deolya is a patented active ingredient recommended in all deodorant care products at a dose of 0.1 to 1.0%. Available in aqueous solution, it complies with biodiversity regulations and has a natural origin content of 99.2% (ISO 16128). It complies with international cosmetics regulations (Europe, USA, China, Japan, etc.).
