Natural Odour Remover Study – Probiotics Eliminate Sweat Odour

Good news! This DENAA+ Probiotic Odour Remover study shows that you no longer need to cover up bad environmental odours with ‘nice smelling’ chemicals: This natural odour remover spray simply eliminates the organic molecules that are causing it. This reduces your exposure to potentially harmful chemicals, which is far better for your health and for the environment.

Although this study focusses on sweat odour, the probiotics eliminate other environmental odour molecules just as well.

Probiotics are a Natural Odour Eliminator

Removing unpleasant odours from indoor air is vital for good health and indoor air quality. This is important whether you are at home, at work or in the gym.

The problem is, most air fresheners are simply artificial fragrances and chemicals. They just add toxins into your indoor air and mask smells without addressing the root causes. They pollute your indoor air, increase the risk of ill-health and worsen your air quality.

In contrast, our Provilan probiotic odour removers simply eliminate the organic molecules that cause bad odours. This removes the odour at its source.

‘Probiotics’ are healthy microorganisms (‘good’ bacteria), naturally-sourced from plants. They are free from harsh chemicals and are safe for respiratory and general health. They work in a safe way that naturally improves indoor air quality.

In this way, probiotic odour control considers health and wellness in a way that chemicals do not. Whether for you, your family, your pets, your clients or your staff.

Different Probiotics Target Different Odours

Different probiotic strains target different types of odour molecules. Our natural odour eliminators therefore contain probiotics specific for their intended use. For example:

  • LUCAA+ Pet Odour Remover is a natural odour remover for pets. Specific probiotics tackle adorable pet smells – wet dogs, urine, smelly cats.
  • DENAA+ Fitness Fresh is a natural odour remover for freshening up clothes. It’s ideal for sweaty trainers and gym kits.

This study focusses on how the probiotics in DENAA+ Probiotic Odour Remover eliminate odour molecules associated with sweat – acetic acid, butyric acid, ammonia and isobutylamine. The DENAA+ range is for offices and other workplaces, shops and busy public buildings where sweat odour can be a problem.

This study shows DENAA+ Probiotic Odour Remover meets standards of effectiveness: VDI 3882 Method – NF EN 13725 Standard.

The Need for Natural Odour Remover

Numerous studies show these Toxic Chemicals in Air Fresheners are very bad for your health. They pollute indoor air and cause illness from asthma and allergies to cancer. These symptoms are even showing up in our beloved pets. (Read our article Polluted Pets to find out more).

The problem is, manufacturer’s can avoid listing toxic ingredients on the label by hiding them as ‘trade secrets’. This can out you at risk of chemical exposure and h associated risks without realising:

  • Benzene and formaldehyde are known to cause cancer.
  • Parabens are linked to breast cancer and hormone disruption.
  • Phthalates are linked to female reproductive system damage, birth defects, and lower sperm counts.

How Probiotic Natural Odour Remover Eliminates Smells – Study

This scientific study shows how DENAA+ Provilan Probiotic Odour Remover eliminates the organic molecules responsible for unpleasant sweat smells – without chemicals. The active ingredient in this natural odour remover spray is ‘good’ bacteria (probiotics). These healthy probiotics feed on the organic molecules that cause bad smells.

This test shows how probiotics are capable of eliminating the molecules associated with sweat – acetic acid, butyric acid, ammonia and isobutylamine.


This in vitro study tested sweat on synthetic sports jackets under three different test conditions. (In vitro means a ‘test tube’ study on microorganisms outside their normal biological context):

  1. Sweat was applied in equal measure to each sports jacket.
  2. Each jacket was subject to different test conditions
    – Jacket 1 – 4 sprays of probiotics only.
    – Jacket 2 – 4 sprays of DENAA+ Probiotic Odour Remover.
    – Jacket 3 – No sprays; control item.
  3. Each jacket was stored in a bag filled with air for analysis.
  4. A panel of accredited experts carried out the scent analysis using the VDI 3882 standards and methods of olfactometry:
    – The hedonic character, which is the perception of unpleasantness of an odour.
    – A description of the sweat odour itself.


The results show that the helpful probiotics – alone and in DENAA+ Probiotic Odour Remover spray – effectively eliminate the molecules associated with sweat odour.
