This scientific study tested how effectively Provilan probiotics and DENAA+ Odour Remover eliminate unpleasant sweat smells from synthetic sportswear – using a scent panel and olfactometric analysis.

The experiment involved three synthetic sports jackets treated under different conditions:

• Sweat control (no product)
• DENAA+ Odour Remover spray
• Probiotics with a fresh natural aroma

Each jacket was sprayed, sealed with air, and assessed by a panel of scent experts using the VDI 3882 method.

Results showed:

• The sweat control sample smelled unpleasant, dominated by acetic acid (vinegar), butyric acid (cheese), ammonia, and isobutylamine (like urine or fish).
• Jackets treated with DENAA+ Odour Remover or Provilan probiotics had neutral odour scores – meaning the unpleasant sweat smell was eliminated.
• The treated jackets were described as fresh smelling, with the strong, unpleasant odours replaced by more pleasant scent notes.

The study confirmed that the probiotics actively break down and outcompete the molecules responsible for bad odours, rather than masking them. The result is cleaner-smelling, fresher fabric that’s free from harsh chemicals and synthetic fragrances.

This demonstrates how Provilan’s probiotic technology offers a safe, effective, and eco-friendly way to remove sweat and body odours from clothing – ideal for sportswear, pet bedding, and everyday fabrics.
