Reducing the Vapor Pressure of a Volatile Compound
NineSigma, on behalf of a global chemicals company, invites proposals for formulation technology or methods to temporarily sequester volatiles, to reduce the vapor pressure of a low-boiling solvent in a water and/or oil mixture, for a packaged goods application.
NineSigma’s client manufactures a chlorofluorocarbon solvent, that boils at room temperature, which they would like to use in multi-ingredient formulations that include water, lipids, surfactants, and other inert ingredients.
NineSigma’s client would like to formulate this solvent in a carrier (mixture) that minimizes premature evaporation during storage (inside a container/packaged goods) but preserves evaporation characteristics upon application to a surface. We encourage you to respond to this request if you have knowledge, methods, or technology which enables a solution.
Table of Chlorofluorocarbon Solvent Physical Properties.
Key Success Criteria
The successful technology will:
Minimize premature solvent evaporation and pressure build-up during storage or shipping (in container/packaged goods) but preserve evaporative properties that occur upon application to a surface
Storage and shipping: temperatures range from 19 to 50 °C, at ambient pressure
Application temperatures range from 20 to 40 °C
Withstand high shear mixing to enable blending with other ingredients
Be compatible with other materials including, but not limited to: lipids, water, surfactants, hydrocarbons, amine/amides, and other inert compounds
Formulated pH ranges from 4 to 9
Use materials with a toxicity profile safe for human exposure
Possible approaches might include, but are not limited to:
Novel carrier matrix geometries such as emulsions, suspensions, hydrocolloids, or gels
Solvent recapture technology
Innovative non-pressured packaging
Approaches not of Interest
The following approaches are not of interest:
Zero-headspace, single-use packaging
Items to be Submitted
Your response should not contain any confidential information.
NineSigma’s client will evaluate all responses and choose those of greatest interest for direct discussions that could lead to contractual engagement for proof of concept demonstration or other commercial arrangements with selected respondent, to develop or adapt promising technologies or approaches.
Your response should address the following:
Description of proposed technology and working principle
Availability of technical data including thermodynamic properties, toxicity profiles, chemical compatibility, and robustness against physical agitation
Technical maturity of the approach (reduced to practice, prototype, ready to commercialize, ready to implement, commercialized)
Pathway to commercial scale including timing, estimated budget, and capacity for manufacture
Estimated unit cost of technology
Position on intellectual property (patent granted, patent pending, trade secret), patent references (if available), and your assessment of freedom to practice
Desired relationship with sponsor
Team description and related experience
