Definitions
- the subject of the present invention is a process for obtaining perfume compositions and perfumed products and the compositions and products thus obtained.
- N-phenyl N-methyl ethyl-2 butanamide more or less common minty notes.
- N, N-dimethyl-2-butanamide thus has a fresh natural mint note more powerful than the homologous N, N-diethylamide whose note-although mint is weaker and peppery.
- N, N-diethylcaprylamide has a different note from N, N-diethyl ethyl-2 butanamide. It follows from the above that it is difficult if not impossible for those skilled in the art to predict whether or not a given alkanamide will have a pleasant odor from an olfactory point of view and what the grade will be.
- the perfume industry is constantly looking for products which, through the originality, volume and power of their fragrance, can give the compositions in which they come in a very special character.
- the present invention relates precisely to the use, in perfumery, of such a compound.
- the subject of the present invention is a process for obtaining perfuming compositions, perfumed substances or perfumed finished products, characterized in that an effective amount is added to the usual constituents of these compositions, substances or finished products.
- N N-dimethyloctanamide.
- the present invention also relates to perfuming compositions, perfumed products and substances characterized in that they comprise, as active principle having an influence on the odor, an effective amount of N, N-dimethyloctanamide.
- This formula product in fact exhales a green, fatty, slightly spicy odor associated with a note of jasmine and lavender which is particularly suitable for floral bases, fern or lavender to which it gives a fresh and natural spicy character.
- fragrance compositions mixtures of various ingredients such as solvents, solid or liquid carriers, fixatives, various odorous compounds, etc., in which N, N-dimethyloctanamide is incorporated, which mixtures are used to provide various types of finished products the desired fragrance.
- Perfume bases constitute preferred examples of perfume compositions in which N, N-dimethyloctanamide can be advantageously used.
- Another example of compositions in which this compound can be advantageously introduced, is represented by the usual detergent compositions. These compositions generally comprise one or more of the following ingredients: anionic, cationic or amphoteric surfactants, bleaching agents, optical brighteners, various fillers, anti-redeposition agents.
- N, N-dimethyloctanamide can be added to any type of detergent composition.
- Toilet waters, aftershave lotions, perfumes, soaps or deodorant products, for example in the form of aerosols, constitute examples of substances or finished products in which N, N-dimethyloctanamide brings its original note.
- N, N-dimethyloctanamide is a colorless liquid, boiling at 96 ° C under a pressure of 2 mm of mercury, very soluble in the usual organic solvents such as alcohols, ketones, esters or ethers.
- N, N-dimethyloctanamide expressed as a percentage by weight in the composition considered depends on the nature of said composition (base for perfume or eau de toilette for example) and on the power and nature the desired effect at the level of the final product. It goes without saying that in a perfume base the content of N, N-dimethyloctanamide can be very high, for example greater than 50% by weight and can reach 90% by weight while in a perfume, an eau de toilette, a after shave lotion or soap, this content may be much less than 50% by weight.
- the lower limit of the content of N, N-dimethyloctanamide may be that which causes a perceptible change in the smell of the fragrance or of the note of the finished product.
- this minimum content can be of the order of 0.01% by weight. It is obviously possible to use contents which are not within the limits of the contents indicated above without departing from the scope of the present invention.
- N, N-dimethyloctanamide can be prepared without difficulty by reacting an octanoyl halide with dimethylamine in the presence of an alkaline base in aqueous solution (soda or potash).
- N, N-dimethyloctanamide strengthens the floral note by bringing the composition a fresh and spicy character.
- N, N-dimethyloctanamide accentuates the lavender note, brings a flowery and fresh side and attenuates the hard note of the base.
- N, N-dimethyloctanamide brings the composition the natural note of lavender by reducing the composite character of the base.
