Olfasense odour quality seal

The Olfasense odour quality seal enables manufacturers to demonstrate the olfactory performance of their products.

The Olfasense odour quality seal with a combined permanent quality assurance process enables manufacturers to highlight unique or particular olfactory properties of their products and have this confirmed by an independent body. That way consumers are supported in their purchasing decision by letting them rely on the independent judgment of a neutral expert.

Below you find the award criteria for the different Olfasense quality seals. Talk to us today to develop the right test design to prove your product claim!

Product claim to be scientifically proven
Odour reduction performance of an anti-odour product compared to a standard product.

Sample preparation
Identical sample preparation of the anti-odour product and the standard product according to conditions that mimic the real-life usage as closely as possible.

Sample evaluation
Human sensory odour measurement of the anti-odour product and the standard product with odour panellists that were selected and trained according to EN 13725.

Awarding of the Olfasense odour reduction seal

The Olfasense quality seal is only awarded if the differences in odour reduction performance between the anti-odour product and the standard product is significant. Significance is achieved in the significance test with a confidence interval of at least 95% (p-value <5%).

As a permanent quality assurance process, the above-described procedure will be repeated annually, or as soon as significant changes are made in the production process of the anti-odour product.

Award criteria for the Olfasense low odour seal

Product claim to be scientifically proven
‘Low odour’ quality of a potentially odorous product compared to a standard product/formulation.

Sample preparation
Identical sample preparation of the ‘low odour’ product and the standard product according to conditions that mimic the real-life usage as closely as possible, for instance by using standardised test chamber conditions.

Sample evaluation
Human sensory odour measurement of the low odour product and the standard product using EN 13725 analysis with odour panellists that were selected and trained according to EN 13725.

Awarding of the Olfasense low odour seal

The Olfasense low odour seal is only awarded in the following circumstances.

For comparing a low odour product to a traditional formulation: if the differences in odour analysis results between the low odour product and the standard product is significant at 95% confidence intervals of analysis results, derived from the performance requirements of EN 13725.

For comparing odour levels of ‘low odour’ formulations against a previously defined ‘low odour product’ (see definition above), then the 95% confidence intervals of analysis results, derived from the performance requirements of EN 13725 must not show a statistical difference.

As a permanent quality assurance process, the above-described procedure will be repeated annually, or as soon as significant changes are made in the production process of the odorous product.
