Definitions

  • 1-cyclopentenylacetic acid of the formula could be used to impart or improve the honey-like fragrant note of perfumes and scented products without having the specific secondary characteristics of phenylacetic acid.
  • the 1-cyclopentenylacetic acid of the invention finds a very wide use both in fine perfumery as in technical applications, for example in the perfuming of soaps, detergents, powder or liquids, maintenance articles or cosmetics, shampoos or beauty creams.
  • the proportions in which the compound of the invention serves to develop the desired odorous effects can vary within a fairly wide range of values. Its power is such that quantities of the order of 1-10 o / oo by weight relative to the weight of the composition or of the scented article may already be sufficient to obtain a positive effect. Concentrations of 0.1-2% are preferably used in the manufacture of concentrated compositions or "hearts".
  • 1-cyclopentenylacetic acid can be added either directly to the product which one wishes to perfume, or, more often, in the form of a solution mixed with other perfuming ingredients.
  • the co-ingredients, the solvents or the usual supports, the use of which is well known to those skilled in the art, are perfectly suited for this purpose.
  • the acid of the invention is a known chemical entity. Its preparation can be carried out in accordance with the methods described [see for this purpose US patent 1,965,792] or from cyclopentylidene-methyl acetate [see US patent 4,280,934] by hydrolysis thereof here following the diagram that here:
  • reaction mixture was kept at 70 ° C overnight, then 2.5 lt of water was added thereto and the methanol was evaporated. After acidification with HCl, separation of the organic phase, followed by re-extraction with ether of the aqueous phase, the two combined organic phases were distilled under reduced pressure.
  • the desired product was obtained with a yield of 82.3% at Eb. 96 ° C / approx. 6.65 Pa. Traces of the isomeric compound of formula were also present in the product obtained, but their presence does not have a practical influence on the quality of the main product.
  • the 2-cyclopentenylacetic acid in solution at 25% in diethyl phthalate was added at a rate of 2% in a commercial soap paste with neutral odor and, according to the usual techniques, the resulting paste was used for the manufacture of bars of toilet soaps.
  • the odor of the article thus obtained was judged by a group of experts who defined it as being characterized by a separate note of the "honey" type.
  • a basic pink-type composition was prepared by mixing the following ingredients (parts by weight):
  • a basic perfume composition intended to be incorporated into a shampoo was prepared by mixing the following ingredients (parts by weight):
  • the olfactory stability was also confirmed by tests of prolonged ultraviolet irradiation of the products obtained.
