EXAMPLES

Example 1: Preparation of a Synthetic Phyllosilicate in Aqueous Gel Form that is Suitable for Use in the Invention

[0659] A synthetic phyllosilicate in aqueous gel form that is suitable for use in the invention is prepared according to the technology described in example 1 of patent application FR 2 977 580 from page 21, line 26 to page 22, line 29.

[0660] It was thus performed up to the formation of the hydrogel without the drying and lyophilization step.

[0661] Analysis of the X-ray diffractogram was performed with the aid of the materials and method used for the X-ray diffraction analyses that are detailed in patent application FR 2 977 580.

[0662] A characteristic diffraction line at 9.77 Å is observed.

[0663] The compositions according to the invention illustrated in the examples that follow comprise a synthetic phyllosilicate in accordance with the invention as obtained in this example 1.

Example 2: Rheological Measurements—Demonstration of the Sol-Gel Transition of a Synthetic Phyllosilicate According to the Invention as Described in Example 1 in the Absence and in the Presence of Aluminum Chlorohydrate

[0664] The rheological measurements and especially the determination of the elastic modulus G′ are performed as indicated above.

[0665] In order to demonstrate the sol-gel transition, two series of tests were performed according to the rheological measurement protocol detailed above.

[0666] The first series of tests consists in testing compositions comprising synthetic phyllosilicate in gel form that is suitable for use in the invention and prepared according to example 1 in the absence of electrolyte and/or polyelectrolyte.

[0667] The second series of tests consists in testing compositions comprising synthetic phyllosilicate in gel form that is suitable for use in the invention and prepared according to example 1 in the presence of an aluminum salt and more precisely in the presence of 15% by weight of aluminum chlorohydrate.

[0668] For each of these series, different concentrations of synthetic phyllosilicate in gel form that is suitable for use in the invention were used, namely: [0669] for the first series: 1%, 2%, 3%, 4%, 7%, 8% and 9.5% by weight; and [0670] for the second series: 1%, 2%, 3% and 4% by weight.

[0671] The results for each of the two series of tests are illustrated in FIGS. 1 and 2.

[0672] It is observed that passing from the liquid state to the gel state takes place at between 4% and 5% by weight of synthetic phyllosilicate active material when the latter is used alone in gel form, whereas the gel state is reached for a lower amount, namely between 2% and 3% by weight of synthetic phyllosilicate active material, when it is combined with aluminum chlorohydrate which is present in an amount of 15% by weight of active material relative to the total weight of the composition.

[0673] Thus, it is demonstrated that the combination of a gel of synthetic phyllosilicate that is suitable for use in the invention with an aluminum salt makes it possible to obtain gels with a lower content of synthetic phyllosilicate.

Example 3: Rheological Measurements and Stability of the Compositions According to the Invention

[0674] Four compositions according to the invention (see table 1) comprising aluminum chlorohydrate as electrolyte are tested.

[0675] The measurement of the elastic modulus G′ is performed as detailed above.

[0676] The stability of the four compositions is evaluated at room temperature (20-30° C.), first after 24 hours, and then second after 2 months. The stability evaluation is performed by observation with the naked eye.

TABLE-US-00001 TABLE 1 Composition Composition 3.1 Composition 3.3 according Composition 3.4 according to 3.2 according to the according to the the invention to the invention invention invention Ingredients (weight %) (weight %) (weight %) (weight %) Synthetic 1 2 3 4 phyllosilicate (% AM*) obtained according to example 1 Water qs qs qs qs Phenoxyethanol 0.7 0.7 0.7 0.7 (Neolone ™ PH 100 Preservative from the company Dow Chemical Company) Aluminum 30 (15% AM*) 30 (15% AM*) 30 (15% 30 (15% AM*) chlorohydrate AM*) (Chlorhydrol 50 ® from the company Summitreheis) G′ (Pa) 0.5 12 2400 23000 24 hr stability Stable Stable Stable Stable 2 month stability Stable Stable Stable Stable AM*: active material

[0677] Thus, it is observed that compositions 3.1 to 3.4 according to the invention remain stable not only after 24 hours, or alternatively after 2 months at room temperature.

[0678] Moreover, it is demonstrated that, within a composition according to the invention, the sol-gel transition takes place at the same concentrations of synthetic phyllosilicate as for the compositions illustrated in example 2, i.e. when the amount of synthetic phyllosilicate in accordance with the invention is between 2% and 3% by weight of active material for an amount of aluminum chlorohydrate of 15% by weight of active material relative to the total weight of the composition. Specifically, as indicated in table 1 above, the elastic modulus G′ varies, respectively, from 12 Pa to 2400 Pa.

Example 4: Rheological Measurements of Compositions According to the Invention and of Comparative Compositions

a Compositions Tested

[0679] One composition (composition 4.1) and three comparative compositions (compositions 4.2, 4.3 and 4.4) are tested.

[0680] In this example, the polyelectrolyte is illustrated by sodium hyaluronate (compositions 4.1, 4.2 and 4.4).

[0681] The synthetic phyllosilicate in powder form included in comparative composition 4.4 is prepared from the synthetic phyllosilicate in aqueous gel form obtained according to example 1, which is subjected to a drying step and then to a milling step.

TABLE-US-00002 Composition 4.1 Comparative according to the Comparative composition 4.3 invention composition 4.2 (weight % of Comparative (weight % of active (weight % of active composition 4.4 material) active material) material) (weight % of Ingredients Aqueous gel Aqueous gel Aqueous gel active material) Water 94 95 95 94 Synthetic 5 — 5 — phyllosilicate in aqueous gel form obtained according to example 1 Sodium 1  1 — 1 hyaluronate (Hyactive ® 120 from the company Contripo) Synthetic — — — 5 phyllosilicate in powder form

b Macroscopic Appearance

[0682] Each composition is evaluated in its jar.

TABLE-US-00003 Composition 4.1 according to the Comparative Comparative Comparative invention composition 4.2 composition 4.3 composition 4.4 Macroscopic texture which does liquid flows at rest fluid; the appearance not flow under its (flows under its synthetic own weight own weight) phyllosilicate in powder form decants

[0683] Only composition 4.1 according to the invention has a texture that does not flow under its own weight.

[0684] Thus, a synthetic phyllosilicate according to the invention in gel form is not destructured by the addition of a polyelectrolyte such as sodium hyaluronate and even contributes toward increasing the viscosity of compositions comprising such a polyelectrolyte. This aspect is corroborated by the rheological characterizations featured below.

[0685] Moreover, a synthetic phyllosilicate in powder form does not make it possible to obtain the expected result especially in terms of viscosity, gelling effect, thickening effect, stability and homogeneity of the deposit.

c Rheological Measurements

[0686] Composition 4.1 according to the invention and the comparative compositions 4.2 and 4.3 were characterized in oscillating rheology according to the materials and methods detailed above, which makes it possible to evaluate the viscous moduli and elastic moduli.

[0687] The liquid or solid nature is determined by the delta value as a function of the applied stress.

TABLE-US-00004 Rheological magnitudes For a stress of 1 Pa Composition 4.1 and a frequency of according to the Comparative Comparative 1 Hz invention composition 4.2 composition 4.3 Elastic modulus G′ 716 ± 50  0.021 ± 0.004 280 ± −20 at the curve plateau Viscous modulus 70 ± 4   0.135 ± −0.007 21 ± −4 G″ at the curve plateau Delta (δ)  6 ± −1 81 ± 2  4 ± 1 CONCLUSION The elastic modulus The product is liquid The elastic modulus G′ G′ value is markedly is higher than the viscous higher than that for modulus G″ the sodium hyaluronate gel alone or for the gel containing 5% synthetic phyllosilicate alone.

[0688] Composition 4.1 according to the invention has an elastic modulus G′ value that is markedly higher than that for the aqueous sodium hyaluronate gel alone (comparative composition 4.2) or for the aqueous gel containing 5% of synthetic phyllosilicate alone (comparative composition 4.3).

[0689] The delta values also show that the aqueous gel containing 1% of sodium hyaluronate (comparative composition 4.2) has “liquid” behavior at rest (delta>45°), whereas the aqueous gel containing 5% of synthetic phyllosilicate in gel form has “solid” behavior (delta<45°).

[0690] Consequently, solutions of active agents that are difficult to formulate such as electrolytes or polyelectrolytes may be gelled by means of the synthetic phyllosilicate used in gel form, which facilitates the application to the skin and the pleasantness of the cosmetic product obtained.

Example 5: Cream of Oil/Water Emulsion Type Based on a Synthetic Phyllosilicate in Gel Form

[0691] Procedure:

[0692] Once the preserving system has been dissolved in water (at the required temperature), the hydrophilic gelling agent is added while stirring with a Rayneri blender at about 70° C. until the gel has homogenized, and the active agent 3-hydroxy-2-pentylcyclopentaneacetic acid is added. The fatty phase was homogenized (at the temperature required to obtain a homogeneous liquid phase). When the mixtures of the two phases were homogeneous, the emulsion was formed by adding the fatty phase to the aqueous phase with stirring using a Moritz blender. The emulsion was cooled with stirring using a Rayneri blender until a homogeneous smooth cream was obtained.

Macroscopic Appearance:

[0693] Composition 5 according to the invention has a stable and homogeneous texture at 24 hr, which does not flow under its own weight.

[0694] Thus, a synthetic phyllosilicate according to the invention in gel form is not destructured by the addition of a polyelectrolyte such as 3-hydroxy-2-pentylcyclopentaneacetic acid.

Example 6: Comparison of the Infrared Spectrum Between Natural Talc and the Synthetic Phyllosilicate that is Suitable for Use in the Invention in an Antiperspirant Composition

[0696] The infrared spectrum of compositions 6.1 and 6.2 was measured.

[0697] The machine used was a Nicolet 6700 FTIR Fourier transform spectrometer, equipped with an integration sphere, with an InGaA detector and a CaF.sub.2 separator and a resolution of 4 cm.sup.−1. In other words, the values of the absorption bands given in this description are to be considered as being more or less 2 cm.sup.−1.

[0698] The near infrared recordings of the stretching region located at 7185 cm.sup.−1 were broken down by pseudo-Voigt functions using the Fityk software (Wojdyr, 2010).

[0699] The compositions were heated to 120° C. and 400° C.

[0700] Stretching amplifications of plus or minus 200 cm.sup.−1 on either side of a suspected absorption band were performed.

[0702] Compositions 7.2 to 7.4 according to the invention and comparative composition 7.1 were characterized in oscillating rheology according to the materials and method detailed above in the description, which makes it possible to evaluate the consistency values G*.
