Definitions

  • the invention relates to the field of perfumes.
  • it relates to a series of esters of 2,2-dimethyl-propionic acid useful as perfume ingredients.
  • Said esters can be represented by the formula in which the symbol R represents a hydrogen atom or a methyl group and Z represents a bivalent radical of formula
  • a more specific subject of the invention is the use of said compounds of formula (I) as perfuming ingredients, in particular their use in the pure state or as a mixture with one or more ingredients perfuming a solvent or a support.
  • esters see for example S. Arctander, Perfume and Flavor Chemicals, Montclair N.J. 1969, Sections nos. 294, 310, 338, 345, 346, 991 and following 7. Whether they are derived from aliphatic or aromatic acids or alcohols, they are almost all cited in the specialized literature. Very surprisingly, however, nowhere is there any mention of the higher esters of 2,2-dimethylpropionic acid (pivalic acid), more particularly of the esters of araliphatic alcohols and, consequently, of the interest that such compounds could have for the perfume industry.
  • the compounds (I) can therefore be advantageously used as perfuming ingredients, in fine perfumery as well as during the perfuming of products such as soaps, detergents, cleaning products or cosmetic products for example. They can be used, among other things, for the preparation of very diverse perfume compositions, such as fruity, floral, rose, lily of the valley or jasmine compositions, for example, even woody, chypre or fern, to which they contribute to give more richness and roundness. .
  • the compounds (I) can be used both in the pure state and in mixture with one or more of the perfuming ingredients usual in the art, a solvent or a support .
  • compositions for perfumes for example, interesting olfactory effects can be obtained by the use of said compounds (I) at a rate of about 1 to 20, sometimes 30% relative to the weight of said composition, or even 50% or more when preparing bases or hearts for perfumes. Amounts less than 1% may also be used, especially when perfuming products such as soaps or detergents for example.
  • the compounds of the invention have the advantage of being perfectly stable in the various environments of use. Their inertia with regard to the effect exerted by acidic, oxidizing or reducing agents, for example, is such that their use can be extended to the scent of very diverse articles such as soaps, hair sprays, talcs or detergents. In addition, their stability with regard to light is also excellent, hence their good storage life. Finally, the compounds of formula (1) have proved to be biologically harmless under the conditions of use envisaged.
  • a basic perfuming composition was prepared as indicated below:
  • the base thus prepared has a generic flowery odor within which there is a characteristic "thrush" note.
  • This perfuming composition is perfectly suited for perfuming shampoos or hair lotions.
