Efficacy Testing


Efficacy Testing

Prior to launching a functional product it is essential to know how effective it is. Measuring the level of efficacy allows for substantive claim support such as “offers 24hr protection”.

WSS offers a range of services for efficacy testing and claim support. We have over ten years experience in testing antiperspirants and deodorants for in-vivo efficacy as well as assessing oral and foot malodour reductions.

To date, we have successfully completed projects on deodorants, antiperspirants, dentifrices and foot products, as well as air fresheners and products designed to combat malodours on fabrics such as towels and bathmats. As well as central location tests, we provide home use placements for assessing products under normal user conditions.



Case Study:

The request

A leading producer of odour control products wanted to measure malodour counteractancy (MOC) of foot and shoe spray products. They had requested fragrance submissions from the major perfume houses and needed to select the most effective across a range of products.

The methodology

An in vitro malodour counteractancy test in glass jars was conducted using a panel of 16 trained assessors. The intensity of a model malodour was assessed several times over a period of 24 hours in the presence and absence of the fragrance submissions.

The results

A report was generated to show the mean assessor scores for malodour intensity and the efficacy in malodour reduction for each fragrance submission. Significant differences were highlighted at 95% confidence to clearly identify where the products differed in efficacy.

The action

Based on the feedback from the research, we were able to demonstrate to our client discernible differences in malodour counteractancy efficacy of the fragrances. The client was then able to select the most effective fragrance for each of their products.
