Sensory odour testing for AqFresh


At Aqdot, we have a high level of expertise & technology available to our AqFresh™ customers in the area of advanced odour sensory testing.

Test methodology

Aqdot uses its own externally validated and trained expert sensory panel to assess the intensity of the untreated malodour control, the treated malodours and any fragrances present on a standard scale from 0-6, as well as the hedonic tone when relevant. For the automotive interiors, the VDA-270 standard industry test protocol is used.

The panel selection and training follow ISO6658 and ISO8586:2012. The test design follow ISO5495 or EN1375. The evaluation, interpretation and statistical analysis of the results follow ISO4121 and ISO 2854.



Sensory scales

Type of results reported

Results are reported on a 0-6 intensity scale, along with their statistical significance.
For example, sensory testing of a fragranced deodorant with AqFresh™ showed a significantly greater fragrance intensity (and lower malodour intensity) when challenged with malodour after 24 hours.
