RFP Title


Measurably Enhancing the Longevity of Fragrance Perception
RFP Description
NineSigma, representing a North American Consumer Products Manufacturer, invites proposals for technologies to improve the lastingness of applied fragrances and their perception. Of critical importance to this program is the ability to more accurately test, measure or validate the efficacy of any proposed solution as compared to current industry standards and protocols.

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.


Anticipated Project Phases or Project Plan

Phase 1 – Proof of concept

  • Details to be determined based upon proposed solution


Phase 2 – Commercial / Industrial scale-up

  • All solutions must pass validation for regulatory, safety and stability testing


Criteria for Moving from Phase 1 to Phase 2

  • Discussion of results including technical data
  • Samples and testing
  • Overview or demonstration of validation protocol
  • Outline of development plan



Key Success Criteria

The successful technology will:

  • Enhance lastingness or retention of fragrance (in whole or part) when applied to skin or fabric;
  • Have no effect on the concentration or the global character of fragrance in the end product;
  • Have a proven, repeatable methodology to validate:
    • Effective lifetime of fragrance in the end product
    • Increase in or improvement of fragrance perception over time as compared to existing products


Additionally, top proposals will address one or more of the following:

  • Compatibility with regulatory and safety requirements for Personal Care Products in North America
  • Functionality in clear systems
  • Give off low or no residual odor
  • Compatibility with alcohol-based solvents
  • Compatibility with liquids, water-base, surfactants, gels, and/or emulsions
  • Discussion of delivery mechanism
  • Scalability of the proposed solution to high volume applications



Possible Approaches

Possible approaches might include, but are not limited to:

  • Cross-industrial approaches involving scents, aromas, flavors or other areas dealing with volatile chemicals that can be adapted to fragrance applications
  • Novel material solutions to extend the longevity of the aroma
    • Encapsulations and coatings
    • Controlled release technologies
    • Novel additives
  • Methodologies to objectively test (both quantitatively and qualitatively) the lastingness of a fragrance.



Approaches not of Interest

The following approaches are not of interest:

  • Solutions based on traditional fragrance blending
  • Solutions that appreciably increase the concentration of fragrance in the end product
  • Solutions that will affect the global character or change the fragrance



Items to be Submitted

    • Working principle or knowledge base to support your approach
    • Availability of technical data
    • Technology maturity (concept, prototype, ready to commercialize, commercialized)
  • Description of any testing or validation methodology employed to prove efficacy of the technology
  • Pathway to industrial scale including timing, estimated budget, and capacity for manufacture
  • Estimated cost of technology (if available)
  • Position on intellectual property including patent references
  • Desired relationship with sponsor
  • Team description and related experience


Other Request information includes:



Respondents from companies (small to large), academic researchers, other research institutes, consultants, venture capitalists, entrepreneurs, or inventors are welcome.
