Synthetic malodour

A key variable in studies to assess the odour reducing products is the source of the odour itself.

Using real odour in tests limits the repeatability of a test design and can result in testing  conducted at different times giving non comparable results.

To counter the influence of such limitations, Sensenet can investigate the key chemical components associated with a range of typical malodours, with the aim to produce synthetic malodour mixtures that contain important constituents from a sensory preceptive for the odour question.

Although the simplified mixtures can never be fully representative of the complex mixture of odorants expected in the real odours, they do represent a mixture of major odours components for each odour type.


 As such testing with these mixtures allows to demonstrate a product performance in reducing the perception of key odorants form a variety of chemical groups.

Sensenet can therefore test product performance using sensory analysis, molecular assessment or a combination of the two!

Sensenet therefore provide different quality of synthetic malodour:

  • Quality A à based on literature only,
  • Quality B à based on the literature and the results of GC-Sniffing molecular analyses of the studied source,
  • Quality C à based on literature, GC-Sniffing analyses and the creative know-how of partner perfumers.

Sensenet can work on the preparation of synthetic malodours reproducing odours, for example of:

  • Garbage
  • Pet odours (‘Wet dog’)
  • Body odour
  • Cooking odours
    • Fat frying
    • Grilled salmon
  • Tobacco smoked/ashtray
  • Faecal
  • Sensenet has over thirty years of experience of odour collection, which allows us to design the collection of representative air samples from almost anything that makes a smell.
  • Sensenet has a state-of-the-art analysis laboratory with GC-Sniffing tool to characterize the main compounds involved in the source odour
  • Sensenet has sensory analysis laboratories both to validate the olfactory similarity of the synthetic malodour with the odour source and to test the product’s performance in reducing such a malodour.

Sensenet will prepare proprietary malodours using a standardized recipe whose constituents have been shown to be contribute to real odours from each test scenario. The advantage of this approach is that it allows a repeatable test condition to be defined, under which the same malodour can be prepared as required.

The recipes have been prepared following an investigation into the chemical composition associated with each malodour, derived from a combination of previous molecular analyses by Sensenet and where appropriate from reputable literature sources. Although the simplified mixtures can never be fully representative of the complex mixture of odorants expected in the real odours, they do represent a mixture of major odorous components for each odour type.

The mixtures are drawn from a knowledge of key odorants from experience, literature and where necessary GC-sniffing.
