Description

ALCOHOLIC FRAGRANCE COMPOSITION COMPRISING ANIONIC TERPOLYMER; PERFUMING PROCESS

The present invention relates to a composition comprising in a cosmetically acceptable medium: a) at least one volatile alcohol in an amount greater than 400/0 by weight relative to the total weight of the composition; b) at least 20/0 by weight relative to the total weight of the composition of a perfume concentrate; C) at least one linear anionic terpolymer, connected or crosslinked, of at least one anionic monomer (1) bearing an acid function in free form, partially or totally salified with a nonionic monomer (2) chosen from NN, dimethylacrylamide and 2-hydroxyethyl acrylate and at least one monomer (3) polyoxyethylated alkyl acrylate of formula (1) which will be defined in detail below.

The present invention also relates to a process for perfuming human keratin materials or a garment which consists in applying to said keratin materials or said garment a perfuming composition as defined above.

The human being has always sought to perfume and perfume the objects that surround him or the places in which he is, and this, both to mask strong and / or unpleasant odors that to give a good smell . It is known that a fragrance is the combination of different odorous substances that evaporate at different times. Each perfume has what is called a "top note" which is the scent diffusing first when applying the perfume or when opening the container containing it, a "heart or body note 30" which corresponds to the complete perfume (emission for a few hours after the "top note") and a "bottom note" which is the most persistent odor (emission for several hours after the "heart note"). The persistence of the base note corresponds to the persistence of the perfume.

It is common to incorporate a perfume concentrate into a number of products or compositions, in particular cosmetic and dermatological such as fresh water, toilet waters, perfume waters, elixirs or perfume extracts, lotions after shaving, care waters, biphasic lotions, perfume creams, after-shave balms. In order to provide a user perceptible and durable odor, perfume concentrates should be used in amounts generally greater than or equal to 20% by weight based on the weight of the composition.

It is conventional to use volatile solvents such as alcohols and in particular ethanol in large quantities in the perfume preparations because they provide the cosmetic preparations with freshness, evanescence by their volatility, and a protection vis-à-vis microbial contamination. They also make it possible to solubilize the perfume concentrate. Unfortunately, perfuming cosmetic preparations containing large concentrations of volatile alcohols are difficult to gel while maintaining acceptable cosmetic qualities.

Indeed, gelling agents such as derivatives of acrylic acid are not very compatible with a large amount of alcohol. It is also known in the prior art to use nonionic gelling agents and in particular cellulose derivatives, but it turns out that these raw materials have an unpleasant sensory perception (sticky, slippery, slippery sensation).

There is still a need to find gelling agents which are (a) compatible with perfume compositions containing large amounts of volatile alcohol (greater than 400/0 by weight) and a minimum perfume concentrate content of 20/0 by weight (b) provide a pleasant sensory perception and (c) do not affect the desired olfactory properties of the composition.

Patent application WO2008 / 087326 discloses linear, branched or crosslinked anionic terpolymer polymers of at least one anionic monomer (1) carrying an acid function in free form, partially or totally salified with a nonionic monomer (2). ) selected from NN, dimethylacrylamide and 2-hydroxyethyl acrylate and at least one polyoxyethylenated alkyl acrylate monomer (3). These polymers are used in cosmetics as thickeners in various cosmetic compositions; they make it possible to thicken or emulsify cosmetic aqueous compositions or to obtain transparent aqueous gels.

The Applicant has surprisingly found that these thickening polymers were a) compatible with perfume compositions containing large amounts of volatile alcohol (greater than 400/0 by weight) and a minimum perfume concentrate content of 20/0 by weight. , b), provided a pleasant sensory perception and c) without affecting the desired olfactory properties of the composition.

This discovery is the basis of the invention.

The invention thus relates to a composition comprising in a cosmetically acceptable medium: a) at least one volatile alcohol in an amount greater than 400/0 by weight relative to the total weight of the composition; b) at least 20/0 by weight relative to the total weight of the composition of a perfume concentrate; c) at least one linear anionic terpolymer, branched or crosslinked, of at least one anionic monomer (1) bearing an acid function in free form, partially or totally salified with a nonionic monomer (2) chosen from NN, dimethylacrylamide and the 2-hydroxyethyl acrylate and at least one polyoxyethylenated alkyl acrylate monomer (3) of formula (1) which will be defined in detail later.

The present invention also relates to a process for perfuming human keratin materials or a garment which consists in applying to said keratin materials or said garment an aqueous perfuming composition as defined above.

CONCENTRATES OF FRAGRANCE

Perfume concentrates are compositions containing, in particular, the raw materials described in S. Arctander, Perfume and Flavor Chemicals (Montclair, NJ, 1969), in S. Arctander, Perfume and Flavor Materials of Natural Origin (Elizabeth, NJ, 1960). and in "Flavor and Fragrance Materials - 1991", Allured Publishing Co. Wheaton, III.

It can be natural products (essential oils, absolutes, resinoids, resins, concretes) and / or synthetic (terpene or sesquiterpenic hydrocarbons, alcohols, phenols, aldehydes, ketones, ethers, acids, esters, nitriles, peroxides, saturated or unsaturated, aliphatic or cyclic).

According to the definition given in the international standard ISO 9235 and adopted by the European Pharmacopoeia Commission, an essential oil is a fragrant product generally of complex composition, obtained from a botanically defined plant raw material, either by training in the steam, either by dry distillation or by a suitable mechanical process without heating (cold expression). The essential oil is most often separated from the aqueous phase by a physical process that does not entail a significant change in the composition.

The choice of the technique depends mainly on the raw material: its original state and its characteristics, its nature proper. The yield "essential oil / vegetable raw material" can be extremely variable according to the plants: 15 ppm to more than 200/0. This choice conditions the characteristics of the essential oil, in particular viscosity, color, solubility, volatility, enrichment or depletion in certain constituents.

Steam Training Steam training corresponds to the vaporization in the presence of water vapor of a substance that is not very miscible with water. The raw material is brought into the presence of boiling water or water vapor in a still. The water vapor causes the essential oil vapor which is condensed in the refrigerant to be recovered in liquid phase in a florentine (or essencier) vase where the essential oil is separated from the water by decantation. The aqueous distillate which remains in steam distillation after the separation of the essential oil is called "aromatic water or" hydrosol "or" floral distilled water ".

Dry distillation

The essential oil is obtained by distillation of wood, bark or roots, without the addition of water or water vapor in a closed chamber designed for the liquid to be recovered in its lower part. Cade oil is the best-known example of this method of production.

Cold expression

This method of production only applies to citrus fruits (Citrus spp.) By mechanical processes at ambient temperature. The principle of the method is as follows: the zests are dilacerated and the contents of the secretory sacs that have been ruptured are recovered by a physical process. The conventional method consists in exerting under a stream of water an abrasive action on the entire surface of the fruit. After removal of solid waste, the essential oil is separated from the aqueous phase by centrifugation. Most industrial plants actually allow the simultaneous or sequential recovery of fruit juice and essential oil.

Physico-chemical characters.

Essential oils are usually volatile and liquid at room temperature, which differentiates them from so-called fixed oils. They are more or less colored and their density is generally lower than that of water. They have a high refractive index and most deflect polarized light. They are liposoluble and soluble in the usual organic solvents, entrainable with water vapor, very little soluble in water.
