[0049] By "compatible with any type of olfactory family" is meant that the complex and / or said composition can contain any type of perfume, from any olfactory family.

[0050] By "stable" is meant a composition or complex that does not degrade over time and whose compounds will not react with each other. By "stable" is meant that the homogeneity, olfactory intensity, olfactory quality, coloration, and / or viscosity of the composition and / or complex are preserved, advantageously without the effect of time, temperature, pressure and / or UV rays. More particularly, the composition and / or the complex according to the present invention is stable in accelerated aging after 24 hours under UV (suntest) and after 2 months at 20-22°C and 45°C in comparison with a sample remaining at 5°C, all the samples being stored at temperature and protected from light, or after centrifugation for a minimum of 12 minutes at a speed of 5000 rpm, for example carried out using a SIGMA model 2-16 K centrifuge or equivalent in comparison with a sample stored at temperature and protected from light.

[0051] By "opaque" is meant that said composition and / or complex is not transparent for temperatures between 4 and 50°C, regardless of the perfume used. The term milky is used as a synonym for opaque. By opaque composition or complex is meant a composition or complex whose turbidity is greater than 3 FNU (Formazin turbidity unit) or 3 NTU (nephelometric turbidity unit). This is measured, for example, using a turbidimeter of the type HI 88713 iso turbidimeter from Hanna instruments or equivalent.

[0052] By "pleasant odor" we mean an odor that is detected by the human sense of smell and is perceived as pleasant.

[0053] By viscous is meant "having a viscosity greater than that of water", i.e. the dynamic viscosity at 20°C of the complex is greater than 15 mPas, preferably greater than 400 mPas, preferably greater than 450 mPas, preferably greater than 1000 mPas, and preferably less than 400,000 mPas, preferably less than 200,000 mPas, preferably less than 15,000 mPas, preferably less than 9,000 mPas. Preferably, according to the present invention, the dynamic viscosity is measured with a HAAKE viscotester IQ rheometer from Thermo Fisher Scientific geometry cc27 dg / ti - 01160025, at 20°C, at 20 s -1 for 30 seconds or equivalent.

Such a composition is intended to provide a pleasant olfactory component.

[0055] By "perfuming substance" we mean one or more raw materials of natural or synthetic origin that are perfumed.

[0056] The percentages are understood as mass percentages, that is to say by weight relative to the weight of the complex or of a composition.

[0057] According to a first aspect, the present invention relates to a perfume complex comprising a perfume, a solvent, a viscosifier, a solubilizer and an opacifier.

[0058] The perfuming complex advantageously comprises a solvent, preferably in an amount of between 10 and 60% by weight of the total weight of the perfuming complex, preferably from 15 to 40%.

[0059] Advantageously, the solvent is chosen from the group comprising glycols and in particular propane-1,2-diol also called monopropylene glycol, 2-[(1-hydroxypropan-2-yl)oxy]propan-1-ol also called dipropylene glycol, or a mixture of these, whether of natural or synthetic origin.

[0060] Advantageously, the solvent is chosen to have a log P between -1 and +1.1. This arrangement makes it possible to control the viscosity of the perfuming complex and / or the perfumed composition.

[0061] Preferably, the solvent is dipropylene glycol. Dipropylene glycol has the CAS number 25265-71-8 and the IUPAC name: 2-[(1-hydroxypropan-2-yl)oxy]propan-1-ol.

[0062] Dipropylene glycol is a mixture of three isomers, 1,1-oxydipropan-2-ol, 1,1'-oxydipropan-2-ol and hydroxypropyloxypropanol, as shown in the table below.

[0063] Its general formula is: C6H14O3.

[0064] Dipropylene glycol is advantageously used in the perfuming complex according to the invention, because it is advantageously almost odorless, colorless and chemically stable. Dipropylene glycol advantageously has a low evaporation power, with a vapor pressure of 0.02 mmHg, i.e. much lower than that of water, which remains the reference with a vapor pressure equal to 17.5 mmHg. Dipropylene glycol is also hygroscopic, miscible with water and most organic solvents.

[0065] Dipropylene glycol is used in particular as a solvent. In perfumery, a solvent is a raw material capable of solubilizing different odorous raw materials, making them compatible with each other, in a beneficially stable and permanent manner.

[0066] It allows to adjust the viscosity, advantageously also the opacity by acting as a diluent. The solvent is used to stabilize the perfume complex. The presence of dipropylene glycol advantageously makes it possible to avoid recrystallization / solidification of the perfume complex and / or the perfumed composition. This recrystallization / solidification can appear following a thermal shock and / or excessive or deficient atmospheric pressure. The crystallization / solidification phenomenon is then irreversible and can occur both on the surface and at the bottom of the perfume complex and / or the perfumed composition. It is recognized by its color, which is whiter than the rest of the perfume complex and / or the perfumed composition and by its granular, non-homogeneous, or even solid appearance.

[0067] The perfuming complex advantageously comprises a viscosifier, preferably in an amount of between 5 and 75% by weight of the total weight of the perfuming complex, preferably from 15% to 70%.

[0068] Preferably, the viscosifier is octahydro-4,7-methano-1 h-indene-5-dimethanol also called tricyclodecanedimethanol, having the CAS number: 26160-83-8. It has the general formula C12H20O2 and the developed formula:

[0069] The function of the viscosifier is to ensure control of the viscosity of the perfume complex according to the invention. The viscosifier contributes to providing a sticky aspect to the perfume complex and / or to the perfumed composition. The viscosifier, and more particularly tricyclodecanedimethanol alcohol, has a very low evaporation confirmed by the value of its vapor pressure equal to 0.750 mmHg while the reference which is water has a vapor pressure equal to 17.5 mmHg. This low evaporation allows the perfume complex to have a slow diffusion. The stickiness provided by tricyclodecanedimethanol alcohol (TCD DM) allows it to adhere to the skin and therefore provides a long-lasting effect, i.e. a lasting effect.

[0070] The viscosifier according to the invention differs from a gelling agent in that a gelling agent operates in an aqueous system, unlike the viscosifier according to the invention, which operates in a water-free system, such as the perfuming complex according to the invention. A non-aqueous system, such as the perfuming complex according to the invention, comprising a viscosifier, has a different rheological profile than an aqueous system comprising a gelling agent.

[0071] Indeed, the present perfume complex has Newtonian behavior, that is to say that its viscosity does not change according to the shear rate, whereas aqueous gels have rheofluidifying behavior, that is to say that their viscosities decrease when the shear rate increases.

[0072] The use of a viscosifier is compatible with the perfumed composition according to the invention in which the diluent is ethanol. Indeed, ethanol would have the effect of breaking the gelling network of an aqueous system and leading to the sedimentation of the opacifying powders.

[0073] The viscosifier, and more particularly tricyclodecanedimethanol alcohol, advantageously contributes to opacifying the perfume complex and / or the perfumed composition. An increase in the quantity of viscosifier, without changing the other quantities by weight of compounds in the perfume complex, increases the opacity of the perfume complex and / or the perfumed composition.

[0074] The perfuming complex advantageously comprises a solubilizer, preferably in an amount of between 0.2 and 16% by weight of the total weight of the perfuming complex, preferably from 0.3% to 8%.

[0075] Advantageously, the solubilizer is chosen from the group comprising Polysorbate 20, Polysorbate 60, Polysorbate 80 or a mixture thereof. Preferably, the solubilizer is polysorbate 20, having the CAS number: 9005-64-5, the general formula C5sHn4O26 and the developed formula:

[0076] Polysorbate 20, also known as Tween 20, or Sorbitan monolaurate, ethoxylated, is a non-ionic surfactant and emulsifier derived from sorbitol made from fruits and berries.

[0077] The solubilizer, and more specifically polysorbate 20, participates in the solubilization of the opacifier within the perfume complex. More specifically, the solubilizer is the solubilizer of the opacifier.

[0078] Indeed, the opacifier tends to be unstable and to form agglomerates within the fragrance complex which are not re-dispersible homogeneously within the fragrance complex. Polysorbate 20 ensures the stability of the opacifier in the fragrance complex and therefore of the fragrance complex and / or the fragrance composition. The solubilizer is used to ensure a homogeneous and stable fragrance complex.

[0079] The choice of polysorbate 20 means that there is no odor, as it is odorless. Furthermore, it is easy to use; it can be processed cold without the need for heating or re-homogenization.

[0080] Advantageously, the solubilizer forms a pre-complex in association with the opacifier and the solvent.

[0081] The perfuming complex advantageously comprises an opacifier, preferably in an amount of between 0.2 and 16% by weight of the total weight of the perfuming complex, preferably from 0.3% to 8%.

[0082] Opacifier is also called whitening agent.

[0083] Preferably, the opacifier is a copolymer of acrylate / styrene and coco glucoside, notably sold under the name Euperlan PCO and having CAS number 141464-42-8 & 9010-92-8. The opacifier is also called D-Glucopyranose, oligomeric, C8-16-alkyl glycosides, methacrylic acid-styrene polymer or in French D-Glucopyranose, oligomer, C8-16 alkyl glycosides and methacrylic acid-styrene polymer.

[0084] The opacifier, and more specifically the acrylates / styrene and coco glucoside copolymer, is a dispersion of an opacifying agent with surfactants.

[0085] The preferred opacifier is a blend of synthetic (styrene / methacrylic acid copolymer) and plant-based (coconut / palm kernel oil, glucose) raw materials. The opacifier is chosen to provide a luxurious, creamy, rich, and dense appearance to the fragrance complex and / or fragrance composition.

[0086] According to the invention, the opacifier is different from an emulsifier. The opacity of the perfuming complex and the perfumed composition is obtained by the opacifier without requiring emulsion by an emulsifier. Preferably, the perfuming complex and / or the perfumed composition are not an emulsion.

[0087] Surprisingly, this opacifier is advantageously suspended, advantageously with the solubilizer and at least part of the solvent (hereinafter referred to as precomplex), before forming a perfuming complex to allow stability of said perfuming complex. Its incorporation as such into the perfuming complex can cause solubility problems and the appearance of agglomerates. The production of a pre-complex comprising the solvent, the solubilizer and the opacifier makes it possible to avoid the formation of these agglomerates. The preparation of this pre-complex is carried out cold. The pre-complex is then mixed with the perfume, then with the viscosifier to obtain the perfuming complex which is homogeneous and stable.

[0088] The fragrance complex advantageously includes a perfume.

[0089] Preferably, the perfume is in sufficient quantity to complete the perfume complex 100%.

[0090] According to the invention, the perfume may comprise ingredients of preferably synthetic, possibly natural origin. The choice of this perfume depends on the one hand on the desired odorant effect and on the other hand on the application in which it will be integrated.

[0091] Such raw materials, whether of natural or synthetic origin, may include esters, ethers, alcohols, aldehydes, ketones, lactones, acetals, nitriles, phenols, acids, terpenes, heterocyclic nitrogen or sulfur compounds, saturated or unsaturated, and complex products of natural origin.
