Description

Fragrance Complex and Scented Water Composition

Field of the invention

The subject of the present invention is a perfuming complex comprising no water and comprising three basic components intended to form, with an aqueous medium, a composition and an advantageously sprayable scented water composition comprising perfume, isopentyldiol and C12. -13 pareth-9, preferably in the form of microemulsion advantageously without ethanol, preferably high perfume dosage and advantageously transparent.

The prior art

In the field of perfumery, a recurring problem concerns the solubility of perfumes in water.

To ensure both sufficient solubility and olfactory performance to the user, it has been found necessary to add certain additives. Such additives have the particular disadvantage of leaving a greasy and sticky touch and for the most part to irritate the skin. They also modify the properties of the solution that contains them such as the viscosity and the proportion of foam formed. Research has focused on the use of several solubilizers and co-solvents, including vicinal diols, poor performance for high perfume assays, such as 1, 2-hexanediol. Such compounds have for some the disadvantage of being very foaming, very sticky and must be heated to be used.

Many currently marketed compositions contain ethanol. However, ethanol is a VOC (Volatile Organic Compound) which is damaging to certain regulatory and environmental constraints. In parallel, research has shown that the presence of water and the decrease or absence of ethanol allowed to increase the tenacity of the perfume over time, to avoid irritation and drying of the skin. and hair, to overcome the risks associated with exposure to the sun and to avoid any problems related to storage, transport (customs) and flammability.

In order to overcome the aforementioned drawbacks, co-solvent-based compositions have been proposed, such as isosorbide, solketal, and ethers thereof, as in WO2014 / 187950 which uses in addition to a of these co-solvents Barsolve Plus, 40-60% Trideceth-9 blend, 20-40% PEG-40 Hydrogenated Castor oil, 5% Polysorbate-20, Solubilizer marketed by Barnet. Compositions comprising ethoxylated oleyl alcohol (marketed as Ameroscol®) or sulphates, such as sodium lauryl sulfate and sodium laureth sulfate, have also been proposed as surfactants. However, such compounds are irritating and drying for the skin and hair and are therefore to be avoided in the field of perfumery and cosmetics.

In perfumery, obtaining an odorant mixture that is both versatile in terms of applications, stable, non-irritating to the skin and has improved sensory properties, is the subject of ongoing research.

Summary of the invention

The invention relates to a perfuming complex which does not comprise water and comprises three basic components: 15 to 45% by weight of perfume, 15 to 50% of isopentyldiol by weight and 15 to 30% by weight of C12-13 pareth-9, the percentages being expressed relative to the total weight of the three basic components.

The perfume complex according to the invention has the advantage of not containing water, which facilitates its transport and conditioning while being stable and non-irritating to the skin.

Advantageously, the perfuming complex does not comprise ethanol. The invention relates to the use of the perfume complex in an aqueous medium.

Indeed, the perfuming complex is intended to be used in an aqueous medium to form in particular a composition according to the invention.

In another aspect, the invention relates to a composition comprising water and the perfume complex according to the invention.

According to one embodiment, the composition is free of ethanol.

According to one embodiment, the composition comprises from 30 to 40% perfume complex.

According to another embodiment, the invention relates to a composition comprising 5 to 40% by weight of perfume, 5 to 30% by weight C12-13 pareth-9pareth-9, and 5 to 30% by weight of isopentyldiol, the percentages being expressed with respect to the total weight of said composition.

It also relates to a cosmetic base, detergent base or room fragrance comprising said composition, advantageously the composition is a cosmetic base, a detergent base or a room fragrance.

It also relates to the use of said composition, said cosmetic base, said detergent base and said ambient perfume to mask bad odors.

Detailed description

The subject of the present invention is therefore a perfuming complex advantageously to obtain a composition and a new perfumed aqueous composition that is advantageously sprayable, which are:

(1) tacky and low foaming,

(2) compatible with any type of olfactory family,

(3) high dosage of fragrance,

(4) that does not evaporate too quickly, and

(5) which has sufficient solubility and olfactory performance.

Indeed, these five criteria can be contradictory. However, the present inventors have had the merit of finding a perfuming complex to obtain a composition and a perfume aqueous composition advantageously sprayable which have an excellent compromise between these different criteria (1) - (5).

The perfume complex according to the invention provides an equilibrium between C12-13 pareth-9 and isopentyldiol. Indeed, the formulation of the perfuming complex without water for its mixing with water must satisfy stability constraints of the complex but also the constraints of the composition mentioned above. The inventors have defined that:

a perfuming complex containing less than 15% by weight of perfume will not make it possible to obtain a sufficiently powerful aqueous scented composition,

a perfuming complex containing more than 45% by weight of perfume will not make it possible to obtain a transparent perfumed aqueous composition whatever the olfactory family,

a perfuming complex comprising less than 15% by weight of C12-13 pareth-9 does not make it possible to solubilize a perfuming complex comprising 15% by weight of perfume and to obtain a transparent and powerful perfumed aqueous composition,

a perfuming complex comprising more than 30% by weight of C12-13 pareth-induces a new aqueous scented composition that is too sticky and foaming,

a perfuming complex comprising less than 15% by weight of isopentydiol does not make it possible to solubilize a perfuming complex comprising 15% by weight of perfume and to obtain a transparent scented aqueous composition

a perfuming complex comprising less than 15% by weight of isopentydiol does not make it possible to obtain an aqueous composition perfumed with a tack-free feel.

a perfuming complex comprising more than 50% by weight of isopentydiol does not make it possible to obtain both a high perfume dosage and a C12-Pareth-9 dosage necessary for solubilization with a view to a transparent aqueous composition .

In addition, said composition developed by the present inventors is advantageous since it can be without ethanol, transparent, stable, low foaming, non-irritating to the skin, pleasant once applied to the skin, has a viscosity close to that of water, has good drying properties, has sufficient olfactory behavior and perception, and / or has improved sensory properties.

Profile test

Preparation of the test

The objective of the test is to highlight the similarities and differences between products in form, including "sensory cards" with 32 panelists.

During this test, 3 descriptors of the perfume were evaluated: "sliding", "absorption" and "scent intensity".

For each descriptor, a precise protocol was given to the panelists so that all panelists evaluate the same identically.

Panellists were also asked to wash their hands between each reference tested with hydro-alcoholic gel provided to avoid cross-contamination.

The evaluated references were coded to evaluate products blind.

By "sliding" is meant the evaluation of the physical property of friction resistance of the product.

For this test, a drop of the composition to be studied is placed on the index of the panelist and a friction movement between the index finger and the thumb of the panelist is performed. It is then evaluated whether the friction is more or less good. The result is reported on a scale of 3 (very good), i.e. the movement is easy, there is no resistance to 0 (unacceptable), i.e. the movement is difficult, there is a strong resistance.

By "absorption" is meant the evaluation of the physical property of penetration of the product.

For this test, a drop of the study composition is placed on the inside of the forearm of the panelist, and the drop is spread out 15 turns of the hand (15 slides). It is then evaluated whether the penetration is more or less good. The result is reported on a scale of 3 (very good), ie the penetration is good and there are no product residues, at 0 (non-acceptable), ie the penetration is bad and there is a residue of product.

"Perfume intensity" means the evaluation of the olfactory property of the product after application.

Following the spreading of the product carried out previously, the panelists placed their noses a few centimeters from their skins, and the level of appreciation of the olfactory intensity of the perfume is evaluated. The result is reported on a scale of 3 (very good), i.e. good perception and Intense scent, 0 (unacceptable), i.e. bad perception and too weak perfume.

Only 2 references are evaluated by test, one on the left arm with application of the product with the right hand and the second product on the right arm with application of the product with the left hand.

Results

The results, ranging from 0 to 3 in steps of 0.5, are shown in FIG.

The composition according to the present invention (scented composition No. 1) has a higher penetration, scent intensity and rub resistance than the comparative compositions A and B studied.

Thus, the composition according to the present invention is significantly better than the comparative scented compositions for the absorption, slip and intensity descriptors of the scent.

Additional tests

After comparing the transparency of Scented Composition No. 1 with that of Comparative Composition B, the present inventors have demonstrated that the use of vicinal diol (see Comparative Composition B) renders the solution opaque. On the contrary, the scented composition No. 1 according to the invention, devoid of vicinal diol, is transparent.

After comparing the transparency of the scented compositions No. 1-6 with that of the comparative composition C, the present inventors have demonstrated that the use of C12-13 pareth-9 in an amount of less than 5% by weight relative to the weight total of the perfume composition makes the scented composition opaque.

After comparing the transparency of scented compositions No. 1-6 with that of comparative composition D, the present inventors have demonstrated that the use of isopentyldiol in an amount of less than 5% by weight relative to the total weight of the perfume composition makes the composition opaque. In particular, by using isopentyldiol in an amount of less than 5% by weight relative to the total weight of the perfume composition, the perfume composition becomes cloudy and becomes opaque.

It has also been demonstrated that the scented compositions according to the present invention (see scented compositions No. 1-6) are transparent under temperature conditions ranging from 4 to 50 ° C, regardless of the scent used (including a perfume containing less than 18% by weight of branched alcohol with at least 8 carbon atoms), at dosages ranging from 5 to 40%.

After studying the intensity of fragrance of scented compositions No. 1 to 6, it has been demonstrated that a composition according to the invention has a higher olfactory degree than that of comparative compositions A, B, C and D. Scented compositions No. 1-6 are low tack and low foaming, do not evaporate too rapidly, and have improved solubility and olfactory performance compared to Comparative Compositions A, B, C, and D.

Comparative Example 5: Comparison C12-13 Pareth-9 against Barsolve Plus

The efficacy of C12-13 Pareth-9 was tested against that of Barsolve Plus, a mixture of 40-60% Trideceth-9, 20-40% PEG-40 Hydrogenated Castor oil, 5% Polysorbate-20, marketed by Barnet ( Table 20).

The ingredients of phase (A) are all added at room temperature to a beaker with stirring. After homogenization, the perfume (B) is added under constant low agitation. The perfume tested here, in phase (B), is composed of 32% by weight of branched alcohols with at least 8 carbon atoms (mixture of citronellol, dihydromyrcenol, ethyl linalool and linalool).

Table 20

Comparative tests of the efficacy of C12-13 Pareth-9 against Barsolve Plus (cited in

WO2014 / 187950)

Legend:

C = clear, transparent

V = veiled, blue

T = turbid, cloudy

D = out of phase

In view of the above results, after comparison of Test 1 with Test 2, at the same dosage of perfume, isopentyldiol and solubilizer, we observe that C12-13 Pareth-9 provides a solution. clear at room temperature unlike Barsolve Plus when used without a co-solvent. The solubilizer C12-13 Pareth-9 therefore has a better solubilization power than the Barsolve Plus. It is therefore concluded that, unlike C12-13 Pareth-9, Barsolve Plus is not effective without co-solvent. C12-13 Pareth-9 is effective without additional cosolvent.

Trials were then performed at higher perfume, isopentydiol and solubilizer dosages (Table 21). It was also tested the addition of a co-solvent, Isosorbide dimethylether, to Barsolve Plus. As the solutions obtained are all clear, stability tests are carried out under the following conditions: 3 days in the refrigerator at 5 ° C, 3 days in a thermostatic cabinet (respectively at 40 ° C, 45 ° C and 50 ° C) and 24h under UV (test performed with Labomat Q-SUN Xe-1-B, Xenon lamp, at a wavelength of 420 nm, with an irradiance of 0.62 W / m ² ).

Table 21

Comparative Tests C12-13 Pareth-9 against Barsolve Plus at high dosages

Based on the results above, after comparing Test 3 with Test 4, we observe that C12-13 Pareth-9 provides better stability at 5 ° C and UV. It is therefore concluded that, unlike C12-13 Pareth-9, Barsolve Plus does not provide a stable solution at 5 ° C or UV when used without co-solvent, when the perfume dosage is 10%. C12-13 Pareth-9 provides a stable 10% perfume solution under all test conditions without additional cosolvent.

Based on the results above, after comparing Test 3 with Test 5, we observe that C12-13 Pareth-9 provides better stability at 5 ° C. It is therefore concluded that contrary to C12-13 Pareth-9, Barsolve Plus does not provide a stable solution at 5 ° C even when used with a co-solvent, when the perfume dosage is 10%. The C12-13 Pareth-9 provides a stable solution with 10% perfume under all test conditions, without additional co-solvent.

Comparative Example 6 Comparison of the Isopentydiol Amounts Required to Obtain Clear Solutions at Room Temperature

Tests were conducted at the same dosage of perfume and solubilizer to determine the amount of isopentyldiol required to obtain clear solutions at room temperature (Table 22).

Table 22

Comparative tests of the quantities of isopentydiol required In view of the above results, after comparison of the tests 3, 6 and 7, the C12-13 Pareth-9 makes it possible to obtain clear solutions at ambient temperature with isopentydiol amounts of 16%, 12% and even 10%. %.

In view of the above results, after comparing tests 4, 8 and 9, Barsolve Plus, used without a co-solvent, makes it possible to obtain clear solutions at ambient temperature only with a 16% isopentyldiol amount. It is therefore concluded that Barsolve Plus used without a co-solvent requires a greater amount of isopentyldiol than C12-13 Pareth-9 to obtain clear solutions at room temperature. In view of the above results, after comparison of the 5, 10 and 11 tests, Barsolve Plus, used with co-solvent, makes it possible to obtain clear solutions at room temperature with isopentyldiol amounts of 16% and 12%. %. It is therefore concluded that the Barsolve Plus used with co-solvent requires a greater amount of isopentyldiol than the C12-13 Pareth-9 to obtain clear solutions at room temperature.

C12-13 Pareth-9 therefore requires less isopentyldiol and does not require any other co-solvent to obtain clear and stable solutions.
