DETECTION OF BODY ODOUR USING A VISUAL INDICATOR STRIP

摘要

The present invention relates to a visual indicating strip for detecting human body odours, more specifically, odours arising from perspiration. The strip includes a section where visual indicating reagents are affixed and another section comprising of a colour intensity scale. The reagents undergo a colorimetric reaction upon contact with the body odour compounds from the skin. In one embodiment of the invention, two reagents, sodium nitrite and acriflavine, are used to detect carboxylic acids in body odour. The colour change the strip and its intensity can be qualitatively assessed using the colour intensity scale. The invention presented forth provides an effective system for detecting body odour in a qualitative and quantitative manner, enabling the application of this ideal system as a personal hygiene check.
