Odor-generating compounds are volatile by nature, so the characteristics of a given scent will naturally degrade and change over time thereby diminishing its potency and impact. The scent that will remain the longest over time is what a consumer will remember of a fragrance (aka. its “signature” or “sillage”). These represent the less volatile compounds, which may evaporate more or less quickly depending on the nature of the fragrance and its composition. As a result, many highly refined fragrances will effectively wear out after application, thus reducing their overall impact.
This issue is further compounded by the well-documented, but poorly understood phenomenon whereby olfactory perception disconnects in the presence of persistent scents and fragrances. In general, when exposed to a specific odor with regularity we tend not to notice it after a latency period of about 20 minutes. For industries such as personal care, food and beverage, or flavor and fragrance, this desensitization presents a major hurdle in instances where a longer-lasting or continual scent is desired.
NineSigma’s client is sponsoring this global RFP to identify partners from across industry with technologies or capabilities that can offset these issues to produce longer lasting fragrances. Top solutions will function on skin and, ideally, on fabric as well. To date the client has investigated a variety of potential solutions that show promise for extending the perceptible duration of an odor, such as esters, film formers and humectants. However, none of them have satisfactorily met the client’s requirements. Furthermore, the efficacy of any given solution is often difficult to ascertain, since traditional testing protocols are highly subjective or not readily repeatable. As such, respondents with the capabilities or expertise to provide a reliable methodology for validating the efficacy of the solution are highly desired.
