[0002] Usually, the perfumes sought are rather transparent and liquid like water.

[0003] In the field of perfumery in particular, there is a growing demand in Middle Eastern countries for ready-to-use perfumes that can be used undiluted, especially with a roll-on applicator. Furthermore, the perfume is required to have a long-lasting diffusion.

[0004] The prior art compositions must be modified to adapt to its new requirements. A fragrance in the form of an opaque and stable alcoholic solution is desired.

[0005] There is therefore a need to propose a composition that meets these requirements. Summary

[0006] To achieve this objective, according to one embodiment, the invention relates to a perfume complex comprising the following components: - a solvent, - a thickening agent, - a solubilizer, - an opacifier, - a perfume.

[0007] This fragrance complex can advantageously be used undiluted, that is, without any other solvent or diluent. This fragrance complex advantageously has a milky appearance and a viscous, sticky feel. The fragrance complex thus adheres to the skin, ensuring slow evaporation and resulting in diffusion throughout the day. The fragrance complex is also stable.

[0009] According to another aspect, the invention relates to a perfumed composition comprising the perfume complex, preferably from 2 to 95% perfume complex by weight relative to the total weight of the composition, and a diluent. This perfumed composition advantageously has a milky appearance and a viscous, sticky feel. The perfumed composition is also stable.

[0010] According to another aspect, the invention relates to the use of the perfumed composition or the perfume complex as all or part of a cosmetic base or a perfumery product, in particular fine perfumery, or of a room fragrance. Detailed description

[0029] By "opaque," it is understood that the composition and / or complex is not transparent at temperatures between 4 and 50°C, regardless of the fragrance used. The term "milky" is used as a synonym for opaque. By "opaque composition or complex," it is understood that the composition or complex has a turbidity greater than 3 FNU (Formazin turbidity units) or 3 NTU (nephelometric turbidity units). This turbidity is measured, for example, using a Hanna Instruments HI 88713 iso tur-bidimeter or equivalent.

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

[0034] By “perfuming substance” is meant one or more perfumed raw materials of natural or synthetic origin.

[0035] Percentages are understood as mass percentage, that is to say, weight relative to a weight of the complex or composition.

[0036] 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.

[0037] The perfume complex advantageously comprises a solvent preferably in an amount between 10 and 60% by weight of the total weight of the perfume complex, preferably from 15 to 40%.

[0038] Advantageously, the solvent is selected from the group comprising propan-2-yl tetradecanoate, diethylbenzene-1,2-dicarboxylate, propane-1,2-diol, 2-[(1-hydroxypropan-2-yl)oxy]propan-1-ol, 1,2,3-triethyl 2-hydroxypropane-1,2,3-tricarboxylate, 2-(2-ethoxyethoxy)ethanol, 2-methylpentane-2,4-diol, 2,2-dimethyl-1,3-dioxolanne-4-ylmethanol, 3-methyl-1,3-butandiol, benzyl benzoate, 1,3-diacetyloxypropan-2-yl acetate, 2-octyldodecan-1-ol, decanoyl and octanoyl glycerides, propan-2-yl hexa-decanoate, ethyl (Z)-octadec-9-enoate, Bis(2-ethylhexyl) hexanedioate, (2-methoxymethylethoxy)propanol, 3-methoxy-3-methylbutan-l-ol, propanol, (2-methoxymethylethoxy)-acetate, ethanol, or a mixture thereof, whether of natural or synthetic origin.

[0039] Advantageously, the solvent is chosen to have a log P between -1 and +1.1. This arrangement allows control of the viscosity of the perfume complex and / or the perfume composition.

[0040] Preferably, the solvent is dipropylene glycol. Dipropylene glycol has CAS number 25265-71-8 and IUP name AC: 2-[(1-hydroxypropan-2-yl)oxy]propan-1-ol.

[0041] Dipropylene glycol is a mixture of three constitutional isomers l,l-oxydipropan-2-ol, l,l'-oxydipropan-2-ol and hydroxypropyloxypropanol presented in the table below.

[0042] [Tables 1] Case No. Common name 108-61-2 [Chem.l] oxydipropan-2-ol 110-98-5 [Chem. 2] 1,1'-oxydipropan-2-ol 106-62-7 [Chem. 3] OH 0¾ hydroxypropyloxypropa nol.

[0043] Its general formula is: C6Hi4O3.

[0044] Dipropylene glycol is advantageously used in the fragrance complex according to the invention because it is advantageously virtually odorless, colorless, and chemically stable. Dipropylene glycol advantageously exhibits a low evaporation rate, with a vapor pressure of 0.02 mmHg, which is much lower than that of water, which remains the reference with a vapor pressure of 17.5 mmHg. Furthermore, dipropylene glycol is hygroscopic and miscible with water and most organic solvents.

[0045] Dipropylene glycol is used in particular as a solvent. In perfumery, a solvent is a raw material capable of solubilizing different odoriferous raw materials, making them compatible with each other in an advantageously stable and permanent manner.

[0046] It allows for adjusting the viscosity and, advantageously, also the opacity by acting as a diluent. The solvent is used to stabilize the fragrance complex. The presence of dipropylene glycol advantageously prevents recrystallization / solidification of the fragrance complex and / or the fragrance composition. This recrystallization / solidification can occur following thermal shock and / or excessive or insufficient atmospheric pressure. The phenomenon of crystallization / solidification This process is then irreversible and can occur both on the surface and at the bottom of the fragrance complex and / or the fragrance composition. It is recognizable by its whiter color compared to the rest of the fragrance complex and / or the fragrance composition and by its granular, non-homogeneous, or even solid appearance.

[0047] The perfume complex advantageously comprises a viscosifier, preferably in an amount between 5 and 75% by weight of the total weight of the perfume complex, preferably 15% to 70%.

[0048] Advantageously, the thickening agent is selected from the group comprising loctahydro-4,7-methano-lh-indene-5-dimethanol, glyceryl hydrogenated rosinate (sold under the name Hercolyn D by DRT), trihydroxystearin (sold under the name Thixcin R PC natural by Elementis), hydrogenated castor oil, paraffin, Solemix Gel Cushion S-00 (proprietary blend sold by Premixel), hydrogenated vegetable oil (sold under the name Dermofeel Viscolid MB by Evonik), polyamide-3 (sold under the name OleoCraft MP-32 Polymers by Croda), oleic polyglyceride / linoleic polyglyceride / linolenic polyglyceride (sold under the name Viamerine 10000 deodorized by Aldivia), and liquid paraffin. (and) Capric / Caprylic Triglyceride (and) Hydrogenated Styrene / Isoprene Copolymer Hydrogenated Styrene / Isoprene Copolymer (sold under the name Transgel 110 by SACI), Cl5-19 Alkane (and) Hydrogenated Styrene / Isoprene Copolymer (sold under the name Veggie gel 407 by Aiglon),Polyterpene resins (sold under the name Dercolyte LTG), the range of rosins (sold under the name Hydrogral by DRT) or mixtures thereof.

[0049] Preferably, the thickening agent is Toctahydro-4,7-methano-lh-indene-5-dimethanol, also known as tricyclodecanedimethanol, having CAS number 26160-83-8. Its general formula is Ci2H2O02 and its structural formula is:

[0050] [Chem.4]

[0051] The viscosifier serves to control the viscosity of the fragrance complex according to the invention. The viscosifier contributes to giving a sticky appearance to the fragrance complex and / or the fragrance composition. The viscosifier, and more particularly tricyclodecanedimethanol alcohol, exhibits very low evaporation. This is confirmed by its vapor pressure of 0.750 mmHg, while the reference vapor pressure of water is 17.5 mmHg. This low evaporation rate allows the fragrance complex to diffuse slowly. The stickiness provided by tricyclodecanedimethanol (TCD DM) ensures adhesion to the skin, resulting in a long-lasting fragrance.

[0052] The thickening agent, and more particularly tricyclodecanedimethanol, advantageously contributes to opacifying the fragrance complex and / or the fragrance composition. An increase in the amount of thickening agent, without changing the other weight amounts of the components of the fragrance complex, increases the opacity of the fragrance complex and / or the fragrance composition.

[0053] The fragrance complex advantageously comprises a solubilizer, preferably in an amount between 0.2 and 16% by weight of the total weight of the fragrance complex, preferably from 0.3% to 8%.

[0054] Advantageously, the solubilizer is selected from the group comprising Polysorbate 20, PEG-30 castor oil (sold under the name Cemulsol B by Solvay), PEG-40 hydrogenated castor oil (sold under the name Eumulgin CO 40 by BTC), glycereth-17 cocoate (sold under the name Levenol C201 by KAO), Polyglyceryl-4 Laurate / Sebacate (and) Polyglyceryl-6 Caprylate / Caprate (and) Aqua (sold under the name Natragem S140-NP by CRODA), Polyglyceryl-3 caprylate (and) caprylyl / capryl glucoside (sold under the name Neocare TGM 8 by Biosynthis), caprylyl / capryl glucoside (sold under the name Oramix CG 110 by Seppic), the Decyl Glucoside (sold under the name Plantacare 2000 UP by BASF), Heptyl Glucoside (sold under the name Sepiclear G7 by Seppic), PPG 26 Buteth-26 (and) PEG 40 hydrogenated castor oil (and) Water (sold under the name Solubilisant LRI by LCW Sensient).

[0055] Preferably, the solubilizer is polysorbate 20, having CAS number 9005-64-5, general formula C58Hii4O26 and structural formula:

[0056] [Chem.5]

[0057] Polysorbate 20, also known as Tween 20, or Sorbitan monolaurate, ethoxylated, is a non-ionic surfactant and emulsifier derived from sorbitol based on fruits and berries.

[0058] The solubilizer, and more particularly polysorbate 20, participates in the solubilization of the opacifier within the perfume complex.

[0059] Indeed, the opacifier tends to be unstable and to form agglomerates within the fragrance complex that are not homogeneously re-dispersible within the fragrance complex. Polysorbate 20 ensures the stability of the opacifier within 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.

[0060] The choice of polysorbate 20 ensures that no unwanted odor is introduced, as it is odorless. Furthermore, it is easy to use; it can be processed cold without the need for heating or re-homogenization.

[0061] Advantageously, the solubilizer forms a pre-complex in association with the opacifier and the solvent.

[0062] The perfume complex advantageously comprises an opacifier, preferably in an amount between 0.2 and 16% by weight of the total weight of the perfume complex, preferably from 0.3% to 8%.

[0063] The opacifier is also called a bleaching agent.

[0064] Advantageously, the opacifier is chosen from the group comprising Styrene / Acrylates Copolymer (and) Coco-Glucoside (sold under the name Euperlan PCO by AMI), Titanium Dioxide (and) Caprylic / Capric Triglyceride (and) Polyhydroxystearic Acid (and) Stearic Acid (and) Alumina (sold under the name Solaveil XT-300-LQ by Croda), micronized Titanium Dioxide or mixtures thereof.

[0065] Preferably, the opacifier is an acrylate / styrene and coco glucoside copolymer sold under the name Euperlan PCO and having CAS numbers 141464-42-8 & 9010-92-8. The opacifier is also known as D-Glucopyranose, oligomeric, C8-16-alkyl glycosides, methacrylic acid-styrene polymer.

[0066] The opacifier, and more particularly the acrylates / styrene and coco glucoside copolymer, is a dispersion of an opacifying agent with surfactants.

[0067] The preferred opacifier is a mixture of synthetic raw materials (styrene / methacrylic acid copolymer) and vegetable raw materials (coconut / palm kernel oil, glucose).

[0068] The opacifier is chosen to give a luxurious, creamy, rich and dense appearance to the perfume complex, and / or to the perfume composition.

[0069] Surprisingly, this opacifier is advantageously suspended, advantageously with the solubilizer and at least a portion of the solvent (hereinafter referred to as the pre-complex), before forming a fragrance complex to ensure the stability of said fragrance complex. Its incorporation as such into the fragrance complex can lead to solubility problems and the formation of agglomerates. Preparing a pre-complex containing the solvent, solubilizer, and opacifier prevents the formation of these agglomerates. This pre-complex is prepared cold. It is then mixed with the fragrance, followed by the thickener, to obtain a homogeneous and stable fragrance complex.

[0070] The perfume complex advantageously comprises a perfume.

[0071] Preferably, the perfume is in sufficient quantity to complete the perfume complex to 100%.

[0072] According to the invention, the fragrance may comprise ingredients of preferably synthetic origin, possibly natural. The choice of this fragrance depends on the desired olfactory effect and the application in which it will be used.

[0073] Such raw materials, whether of natural or synthetic origin, may include esters, ethers, alcohols, aldehydes, ketones, lactones, acetals, nitriles, phenols, acids, terpenes, nitrogenous or sulfurous heterocyclic compounds, saturated or unsaturated, and complex products of natural origin.
