Definitions

• the present invention relates to stock solutions containing cyclohexylidene phenyl acetonitrile, and to consumer products containing same.
• Cyclohexylidene phenyl acetonitrile (known more commonly by the name PEONILETM) is a highly valued perfume ingredient, having an odour that has been characterised as flowery- rosy, green, metallic, and pronounced of geranium.
• PEONILETM is powerful, relatively nonvolatile and is very stable in almost all media. It has very high substantivity on wet and dry laundry and helps to increase volume and tenacity in functional perfumes. Accordingly, it has been widely used in all manner of consumer products from fine fragrances, through cosmetics, personal care and household care products. The molecule, and its use as an odourant, are described in US 6,069,125.
• the melting point of a specific target substance can be depressed by mixing it with a second substance, which second substance has i) a lower melting point, or ii) forms a eutectic mixture with the target substance.
• the target substance and the second substance must be thermodynamically compatible (i.e. they should not phase separate) across the entire temperature range within which one requires a liquid state.
• liquid mixtures that are thermodynamically compatible below their liquid-solid phase separation temperature must remain so even if an impurity is inadvertently or deliberately added to the liquid mixture, or if the liquid mixture is brought into contact with a surface, which could create crystal nucleation sites.
• the mixture of the target substance and the second substance must be olfactively acceptable from a perfumery standpoint, that is, the mixture of substances should have an odour direction and odour intensity that is substantially similar to the pure target substance.
• liquid organic substances such as liquid fragrance materials and solvents might produce thermodynamically compatible binary mixtures with cyclohexylidene phenyl acetonitrile over broad temperature ranges. However, this was also found not to be the case.
