Leaf alcohol (cis-3-hexenol) is a fragrant compound naturally produced by plants widely used in the flavor and fragrance industry. Hence, good manufacturing processes that can meet this high demand are needed. Do you have a process to manufacture natural cis-3-hexenol at an industrial scale and in the most cost-effective manner possible? 

This is a Reduction-to-Practice Challenge that requires written documentation, experimental data, and sample delivery.



Cis-3-hexenol (leaf alcohol) is a fragrant compound naturally produced by plants. Its characteristic odor has made it a highly successful natural green compound in the flavor and fragrance industry. High demand for this ingredient makes it a constant challenge for the industry to develop processes that can, at a low production cost per kg, allow for the consistent, sustainable and high-quality manufacturing of multi tones of this product. 

Hence, the Seeker is challenging scientists and technologists to come up with whole processes (from production to downstream processing) to meet this need. Please read the Detailed Description section to learn about the technical requirements that your proposed process should meet. 

The submission to the Challenge should include the following: 

  1. The detailed description of the proposed Solution addressing specific Technical Requirements presented in the Detailed Description of the Challenge. This description should be accompanied by a well-articulated rationale supported by literature/patent precedents.
  2. Experimental data obtained as outlined in the Detailed Description of the Challenge (and/or delivery of a material sample of the product if requested by the Seeker).   

The Challenge award is contingent upon theoretical evaluation and experimental validation on a 15 L pilot scale of the submitted Solutions by the Seeker. 

To receive an award, the Solvers will have to transfer to the Seeker their exclusive Intellectual Property (IP) rights to the solution. 

Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on August 18, 2016. Late submissions will not be considered.


What is InnoCentive?
InnoCentive is the global innovation marketplace where creative minds solve some of the world's most important problems for cash awards up to $1 million. Commercial, governmental and humanitarian organizations engage with InnoCentive to solve problems that can impact humankind in areas ranging from the environment to medical advancements.

What is an RTP Challenge?

An InnoCentive RTP (Reduction to Practice) Challenge is a prototype that proves an idea, and is similar to an InnoCentive Theoretical Challenge in its high level of detail. However, an RTP requires the Solver to submit a validated solution, either in the form of original data or a physical sample. Also the Seeker is allowed to test the proposed solution. For details about treatment of IP rights, please see the Challenge-Specific Agreement.
