Description

[0001] DEODORANT POWDER COMPOSITION

[0002] FIELD OF THE INVENTION

[0003] The present invention relates to novel cosmetic compositions, their manufacturing process and their use, in particular as a deodorant. The present invention also relates to a device comprising said novel cosmetic compositions.

[0004] PREVIOUS ART

[0005] Everyone sweats: this process is essential for the body to function. It helps, for example, to maintain a constant body temperature of 37°C. As a result, when the body temperature rises, the brain, via the nervous system, orders the secretion of sweat by the sweat glands so that the heat is evacuated, and the temperature of the skin and the body drops. In normal times (without sustained physical effort or excessive heat), the body produces about 0.5 L of sweat per day, particularly in the armpits, hands, feet, face and groin, areas where many sweat glands are present.

[0006] In 1888, the American brand “Mum®” reportedly created the first antibacterial deodorant. This product was a zinc oxide-based paste applied under the armpits. Other products followed and were distributed in various ways, including powders, liquids, creams, sticks, squeeze bottles, roll-ons, aerosols, and pumps, with different forms becoming more or less popular over time. For example, US application 2006 / 045860 describes a powdered deodorant composition comprising dimethicone, zinc zeolite, corn starch, and vitamin K; and RU application 232229 discloses a deodorant composition in the form of a powder (20-30 μm) comprising calendula oil, zinc oxide, kaolin, abscorbic acid, and perfume.

[0007] The same fate has befallen preservatives, alcohols, parabens, triclosan, phthalates, silicone, etc., and other disadvantages are listed by consumers regarding the use of modern deodorants. For example, the presence of stains and the nonsense of applying a wet product when a dry skin sensation is desired.

[0008] BRIEF OVERVIEW

[0009] To meet current needs and provide the ideal deodorant, the inventor has formulated a new cosmetic composition in powder form. Therefore, one of the primary aims of the invention is to provide this new powdery cosmetic composition and its cold preparation process (i.e. without heating). Another aim of the invention is to propose its use as a deodorant. Another aim of the invention is to provide a device for its application.

[0010] DETAILED DESCRIPTION

[0011] According to a first aspect, the invention relates to a powdery cosmetic composition consisting of or comprising:

[0012] ■ an oil, in oily form;

In particular, the subject of the invention is the powdery cosmetic composition as described above, in which the total amount of said zinc is 0.5% by mass relative to the total mass of said powdery cosmetic composition.

[0060] The expression "powder adhesion agent" designates a support which allows good adhesion of the powders. This is an agent allowing the adhesion of the different constituents and ingredients of the powder, and to modify the rheology of the powdery cosmetic composition of the invention during its use. These are more particularly viscosity modifying additives allowing the texture of the powdery cosmetic composition of the invention to be modified during its use. The powder adhesion agents which can be used in the present invention are in particular carbohydrate-based biopolymers.According to another embodiment, the invention therefore relates to the powdery cosmetic composition as described above, said powder adhesion agent being chosen from: corn starch, acacia powder, maltodextrin powder, tapioca powder, rice powder, rice starch, rice bran extract, arrowroot powder, almond milk powder, oat powder, an oat extract and a mixture thereof, in particular said adhesion agent being corn starch and / or maltodextrin powder.

[0061] According to another embodiment, the invention relates to the powdery cosmetic composition as described above, said adhesion agent being corn starch and / or maltodextrin powder. The invention can therefore use corn starch, or maltodextrin powder, or a mixture of corn starch and maltodextrin powder.

[0062] According to another embodiment, the subject of the invention is the powdery cosmetic composition as described above, in which the total amount of said powder adhesion agent is from 45% to 60% by mass relative to the total mass of said powdery cosmetic composition. This therefore means that this total amount of said powder adhesion agent may be from 45% to 55%, from 52% to 58%, from 50% to 55%, from 55% to 60%, from 55% to 56% or from 57% to 58% by mass relative to the total mass of said powdery cosmetic composition.

[0063] In particular, the subject of the invention is the powdery cosmetic composition as described above, in which:

[0064] ■ the total quantity of said corn starch is from 50% to 60% (in particular from 50% to 58%) by mass relative to the total mass of said powdery cosmetic composition, and is in particular 50.2% or 53.5% or 57.5%; and

[0065] ■ optionally, the total quantity of said maltodextrin powder is from 0.1% to 0.3% (in particular from 0.2% to 0.3%) by mass relative to the total mass of said powdery cosmetic composition, and is in particular 0.25%.

[0066] In particular, the invention also relates to the powdery cosmetic composition as described above, in which said adhesion agent is a mixture of corn starch and a maltodextrin powder:

[0067] ■ the total quantity of said corn starch being from 50% to 40% (in particular from 50% to 58%) by mass relative to the total mass of said pulverulent cosmetic composition, and being in particular 50.2% or 53.5% or 57.5%; and

[0068] ■ the total quantity of said maltodextrin powder being from 0.1% to 0.3% (in particular from 0.2% to 0.3%) by mass relative to the total mass of said powdery cosmetic composition, and being in particular 0.25%.

[0069] The term "antioxidant" refers to substances used to prevent the rancidity of said oil, which is caused by the oxidation of vegetable oils and butters upon contact with air. This phenomenon is accelerated by light (UV), temperature, contact with pro-oxidant metals (Iron or Copper), the presence of pigments such as chlorophyll or the presence of enzymes (lipases, etc.). Oxidation is easily identifiable because it is responsible for a change in the appearance of the vegetable oil (rancid smell, change in color). There are several methods for determining the oxidative stability of lipids:

[0070] - Measurement of absorbed oxygen: This method allows the course of oxidation to be monitored simultaneously and the oxidation index of the treated oil to be measured. Absorbed oxygen is measured by volumetric or electrochemical methods.

[0071] - Oven method or Shaal test: The test consists of oxidizing the fat in a lit oven at 60°C. The detection of oxidation is shown by measuring the peroxide index on samples taken every 4, 8, or 24 hours. This method has the advantage of being close to real storage conditions (case of transparent bottles of oils stored in daylight and at room temperature).

[0072] - Rancimat Test: This test is widely used to assess the oxidative stability of fats. The TIR specification (Rancimat Test Induction Time, expressed in hours) corresponds to the time during which the fat has resisted oxidative stress. The principle of the test consists of prematurely aging the fats by thermal decomposition at 98°C, under intensive bubbling of air. The organic acids, degradation products of this advanced oxidation, are carried by an air current and collected in a measuring cell filled with distilled water. The induction time is determined by conductimetry and corresponds to the TIR. The Rancimat test offers the advantage of monitoring several samples in parallel, with reduced analysis times.

[0073] Advantageously, the invention relates to a powdery cosmetic composition as described above, said powdery cosmetic composition exhibiting an absence of rancidity of the oil.

[0074] In the invention, the use of said antioxidant does not affect the microbial stability of the powdery cosmetic composition of the invention. It should be noted that as antioxidants, the following may be mentioned: a tocopherol (e.g. vitamin E), a mixture of tocopherols (e.g. Covi-ox® T 90 C sold by BASF), ascorbic acid (vitamin C) and an ascorbic acid derivative (e.g. ascorbyl glucoside). According to another embodiment, the invention therefore relates to the powdery cosmetic composition as described above, said antioxidant being chosen from: a tocopherol, a mixture of tocopherols (eg Covi-ox® T 90 C), ascorbic acid (vitamin C), an ascorbic acid derivative (eg ascorbyl glucoside) and a mixture thereof, in particular said antioxidant being a tocopherol, a mixture of tocopherols (eg Covi-ox® T 90 C) or vitamin E.

[0075] According to another embodiment, the subject of the invention is the powdery cosmetic composition as described above, in which the mass percentage of water relative to the total mass of said powdery cosmetic composition is less than or equal to 10%. In particular, the subject of the invention is the powdery cosmetic composition as described above, in which the mass percentage of water relative to the total mass of said powdery cosmetic composition is from 0% to 10%, in particular from 0% to 5%. Given the current context, water has become a rare and precious resource that must be safeguarded at all costs for future generations. Since its presence has no place in a deodorant, the development of the cosmetic composition of the invention in the form of a dry powder has made it possible to achieve this goal.Advantageously, the absence of water in the invention allows it to be manufactured cold, which preserves the active ingredients; to remove preservatives; and also to avoid plastic bottles.

[0076] According to another embodiment, the invention relates to the powdery cosmetic composition as described above, said antioxidant being a tocopherol, a mixture of tocopherols (eg Covi-ox® T 90 C) or vitamin E.

[0077] According to another embodiment, the subject of the invention is the powdery cosmetic composition as described above, in which the total amount of said antioxidant is from 0.1% to 1% (in particular from 0.3% to 0.7%) by mass relative to the total mass of said powdery cosmetic composition, and is in particular 0.5%. In particular, the subject of the invention is the powdery cosmetic composition as described above, in which the total amount of said antioxidant is 0.5% by mass relative to the total mass of said powdery cosmetic composition.

[0078] In cosmetics, the term "prebiotic" refers to ingredients that promote the balance of the skin microbiome, the community of microorganisms living on the skin's surface. They nourish good bacteria, thus strengthening the skin barrier and improving the skin's resistance to external aggressions.

[0079] In cosmetics, the term "probiotic" refers to beneficial microorganisms incorporated into products to promote a balanced skin microbiome. They can strengthen the skin barrier, reduce inflammation, and improve skin health.

[0080] As mentioned above, the powdery cosmetic composition of the invention comprises a prebiotic, in powder form, and / or a probiotic, in powder form.

[0284] Laser diffraction measures particle size distributions by measuring the angular variation of scattered light intensity when a laser beam passes through a sample of dispersed particles. Large particles scatter light at small angles to the laser beam, and small particles scatter light at larger angles. The scattered intensity versus angle data is analyzed to calculate the particle size that created the diffraction pattern using Mie theory. Particle size is represented by the diameter of the equivalent sphere, having the same volume as the particle. The measurements performed in Laser Particle Sizing are inspired by ISO 13320:2009. The analyses were performed in triplicate. Analysis parameter

[0298] Example No. 3 - Measurement of water activity (Aw)

[0299] METHOD OF OPERATION

[0300] Device Description

[0301] The HygroPalm AW1 is a portable device that measures water activity and temperature. The measurement was carried out by a HygroClip AW-DIO sensor, which is a measuring chamber into which the sample contained in a suitable cuvette was introduced.

[0302] Carrying out the test

[0303] Fill the container to the correct level and do not put the lid on.

[0304] Place the sample in the cuvette.

[0305] Place the HygroClip AW-DIO sensor on the bowl.

[0306] Connect the HygroClip AW-DIO sensor to the HygroPalm AW1 and turn on the device.

[0307] The device has been programmed to AwQuick mode. To change the mode:

[0308] ■ Press MENU o Then press ENTER, o Select the desired mode using the arrows, o Confirm by pressing ENTER 3 times. o Return to the main screen.

[0309] To start the measurement, press ENTER.

[0310] The red LED on the HygroClip AW-DIO sensor is flashing during measurement. If the LED is not flashing, check the sensor connection. The humidity trend display appears after 60 seconds. Two arrows indicate stable temperature and humidity values. When the steady state is reached, the device freezes the display and two black rectangles indicate the end of the measurement.

[0311] Repeat the measurement 2 more times and take the average of the three measurements. Record the result.

[0312] Precautions for sampling:

[0313] Water activity measurement should be carried out in a room at a stable temperature.

[0314] Do not place the appliance next to a heater, water pipe or open window.

[0315] The samples must be in the same climatic conditions as the sensor. Therefore, it will be necessary to allow time for adaptation to ambient temperature before taking a measurement. Do not take measurements immediately after manufacturing.

[0316] Example No. 4 - Measurement of (apparent) density and tapped density

[0317] METHOD OF OPERATION

[0318] Setting up and switching on the device

[0319] Turn on the device (SOTAX TD1) by placing the switch on the back of the device in position I and wait for the device to start (home screen display).

[0320] The device is supplied with two graduated cylinders, one of 100 mL and the other of 250 mL.

[0321] Sample preparation

[0322] The equipment used must be perfectly dry before use.

[0323] Add approximately 230 mL of the sample to be analyzed into the 250 mL graduated cylinder, taking care not to pack the powder. Record the weight of this quantity of powder introduced.

[0324] Carrying out packed and unpacked density measurements

[0325] Unpacked density or bulk density

[0326] Once the test tube is filled with approximately 100 g of the sample, read the volume and calculate the mass (g) / volume (mL) ratio. This ratio corresponds to the density of the sample. The density is calculated by dividing this value by the density of water (i.e. 1 g / mL at room temperature [20°C]). mass powder (g) unpacked density = - : - : — - — — — volume read (mL)

[0327] Packed density

[0328] The measurement of the tapped density is carried out with the test tube filled to 230 mL (the same as for the untapped density).

[0329] Place the test tube on the support and secure it with the black ring, rotating it.

[0330] Place this assembly on the device. A support can be used for placing the test piece. Its presence defines the proposed method for performing the measurement (see below).

[0331] Press the button to enter the menu.

[0332] Turn the dial to go to “Method” and press to confirm.

[0333] - If the support has been placed, only the USP2 method can be used (example above).

[0334] - In the absence of support, both USP1 and USP2 methods are available.

[0335] The two methods differ in the speed of the strokes: 300 strokes / min for USP1 and 250 strokes / min for USP2.

[0336] A “User” method can also be chosen and allows the method (number of moves) to be manually defined.

[0337] Confirm the method by pressing the button. The screen displays the method details. Scroll to the bottom of the screen with the wheel and press "Save and exit" to confirm.

[0338] Enter the “Start” menu and enter the initial mass of the powder introduced and the initial volume (values ​​used to calculate the unpacked density) by turning the dial. Confirm by pressing “Continue”.

[0339] When validating, a message appears to check the presence of the support with the test piece. Validate “Start test”.

[0340] The device begins to pack. At the end of each series of strokes, read the value on the graduated cylinder and enter it on the screen by turning the dial and pressing to validate and continue the method.

[0341] Using the example of the USP2 method, the one that was implemented, it is necessary to enter the values ​​read on the test tube after the series of: 10 shots, 490 shots, 750 shots and 1,250 shots.

[0342] After these series, repeat a series of 1,250 strokes until the value read on the test tube between 2 successive series is less than 2 mL. This indicates the end of the measurement.

[0343] At the end of the measurement, the results appear on the screen:

[0344] - Reminder of the method

[0345] - Tap density and untapped density.

[0346] - Compressibility index providing information on the powder's ability to compact ("compressibility index")

[0347] - Hausner index (“Hausner ratio”): this is a dimensionless quantity equal to the ratio of the packed density to the unpacked density, which provides information on the flow properties of the powder.

[0348] - Reminder of the volumes read after each series of shots.

[0349] Example No. 5 - pH Measurement

[0350] The powdery cosmetic composition according to the invention was weighed and diluted in water to obtain an aqueous solution comprising 10% by mass of the powdery cosmetic composition. The pH was then measured at room temperature (ranging from 18°C ​​to 28°C, in particular 20°C), using a pH meter.

[0351] Example No. 6 - Formulation No. 1 of a powdery cosmetic composition according to the invention

[0352] Table 1. List of ingredients of Formulation No. 1

[0353] The particle size analysis showed (Figure 3 - Table 2) that:

[0354] ■ the analyzed sample has particle sizes ranging from 0.13 pm to 127 pm; ■ the main population is centered at a diameter of approximately 11 pm;

[0355] ■ there are 3 minor populations that were detected at approximately: 0.4 pm, 2 pm and 67 pm; and

[0356] ■ the percentage of particles with diameters less than 10 pm is 45%.

[0357] Table 2. Granulometry analysis

[0358] The value in solid corresponds to the “X” used to interpret the Indexes.

[0359] After carrying out all the texture analyses, the powdery cosmetic composition obtained was finally presented in the form of a flesh-colored powder (nude appearance) and characterized by:

[0360] ■ a particle size distribution with particle sizes ranging from 0.13 pm to 127 pm, in particular centered at a diameter of 11 pm;

[0361] ■ a water activity of 0.183 ± 0.014 Aw at a temperature of 26.1 ± 0.27°C;

[0362] ■ an apparent density of 0.44 to 0.48 g / cm 3at a temperature of 20°C; ■ a packed density of 0.68 g / cm 3 at a temperature of 20°C; and

[0363] ■ a pH between 5 and 6 at a temperature of 20°C.

[0512] The study was carried out according to the following schedule: Day JO, before any application of the product:

[0513] ■ The subject(s) come to the study center without having applied any cosmetic product to the application area since the previous evening,

[0514] ■ Information of the subject(s) on the purpose and progress of the test.

[0515] ■ Clinical examination carried out by the investigator, to confirm the inclusion of the volunteer in the panel, to assess the skin condition of the treated areas,

[0516] ■ Each volunteer is given: the product to be applied and the cosmetic acceptability questionnaire.

[0517] From D1 to Dfinal:

[0518] ■ Subjects use the product according to the recommended instructions and for the defined duration. They respond to the questionnaire at the end of the period of use.

[0519] Day D21, after 3 weeks of daily application under normal conditions of use:

[0520] ■ The subject(s) return to the study center,

[0521] ■ Search for clinical signs during a clinical examination carried out by the investigator,

[0522] ■ Collection of any feelings of intolerance experienced during the study,

[0523] ■ Collection of completed questionnaire responses and remaining product by volunteers.

[0524] 4. PRODUCT TOLERANCE

[0525] The tolerance study takes into account the evaluation of clinical signs observed by the dermatologist and subjective signs reported by the volunteers.

[0526] 4.1. CRITERIA FOR EVALUATING SKIN TOLERANCE

[0527] The skin condition and sensations of intolerance localized at the application area were evaluated by the dermatologist on the one hand (clinical signs: Erythema, Edema, Skin dryness and Others) and by the volunteers on the other hand (subjective signs: Burning, Itching, Tingling, Tightness and Others).

[0528] The assessment of the signs was carried out according to the following scales and ratings:

[0529] 4.2. OVERALL EVALUATION OF SKIN TOLERANCE

[0530] 4.2.1. Relevance of tolerance signs

[0531] To avoid any confusion with signs not attributable to the product, we take into consideration the relevance of the signs.

[0532] The relevance of a sign is defined as follows:

[0533] ■ the average duration of the sign is greater than a score of 0.5 (five minutes) and

[0534] ■ the relationship with the tested product is possible or certain (imputability),

[0535] ■ the duration of the sign over time is greater than or equal to a quarter of the total duration of the study (subjective signs).

[0536] This leads to the exclusion of signs of null or doubtful imputability as well as signs persisting only a few days at the start of the study.

[0537] 4.2.2. Calculation of the Percentage of relevant sign

[0538] The P percentages of relevant signs are calculated for signs of low intensity (PI), moderate intensity (P2), and significant intensity (P3), according to the formula below:

[0539] Number of relevant signs x 100

[0540] P % of relevant sign = - - -: -: -

[0541] Number of subjects

[0542] The PTOTAL percentages for all relevant signs are calculated for signs of low (PTotall), moderate (PTotal2) and significant (PTotal3) intensity, according to the formula below:

[0543] Number of relevant signs x 100

[0544] PTOTAL % of relevant sign = — - : - : - -, — : — -, - : - : -

[0545] Number of signs assessed x number of subjects The percentage of relevant signs with the highest intensity is retained to assess tolerance.

[0546] 4.2.3. Assessment of subjective tolerance and clinical tolerance

[0547] The tolerance study comprises two successive phases, the first analyzing the percentage P of relevant signs reported by the volunteers, the second doing the same with the relevant clinical signs noted by the dermatologist.

[0548] The PTOTAL percentage of relevant subjective signs on the one hand and the PTOTAL percentage of relevant clinical signs on the other hand are assessed according to the scale presented in table 8 below:

[0549] 4.2.4. Assessment of overall tolerance

[0550] The overall tolerance retained corresponds to the worst conclusion concerning clinical tolerance and subjective tolerance taking into account possible additional studies and the interpretation of information from each subject.

[0551] 5. COSMETIC ACCEPTABILITY

[0552] After 3 weeks of using the cosmetic composition produced in Example No. 10, the volunteers answered the questionnaire.

[0553] All responses given were analyzed from a statistical point of view. The percentage of positive responses corresponds to the average of the percentages of positive responses to questions Q1 to Q20.

[0554] 6. RESULTS

[0555] 6.1. CHARACTERISTICS OF VOLUNTEERS

[0556] 20 volunteer subjects were selected in accordance with the inclusion criteria and non-inclusion criteria and completed the entire study.

[0557] Table 9 below presents a summary of the observations concerning the included subjects. 6.2. SKIN TOLERANCE

[0558] The analysis of the results was carried out on 20 volunteers.

[0559] 6.2.1. Subjective tolerance (Tl)

[0560] No signs of discomfort were noted by the 20 subjects after 3 weeks of use.

[0561] Under the conditions of this study after 3 weeks of application, the subjective tolerance (Tl) of the tested product was considered excellent.

[0562] 6.2.2. Clinical tolerance (T2) No clinical manifestations were observed by the investigating physician, after 3 weeks of use, in the 20 subjects.

[0563] Under the conditions of this study after 3 weeks of application, the clinical tolerance (T2) of the tested product was considered excellent.

[0564] 6.2.3. Interpretation of results

[0565] Product tolerance is defined from the synthesis of subjective signs (Tl) and clinical signs (T2), analyzed in terms of the relevance of the signs. In accordance with the principles set out in paragraph 6.2., the overall tolerance appears in bold in Table 13 below:

[0566] 6.3. COSMETIC ACCEPTABILITY

[0567] After 3 weeks of using the cosmetic composition produced in Example No. 10, all volunteers responded to the questionnaire. The summary of the responses obtained by evaluation sector is presented below.

[0568] 7. CONCLUSIONS

[0569] Under the conditions of this study, after 3 weeks of application, by 20 volunteers, the cosmetic composition produced in Example No. 10 showed excellent skin tolerance. In the single-choice evaluation questionnaire relating to the cosmetic composition produced in Example No. 10:

[0570] ■ 70% of responses were in favor of the composition,

[0571] ■ 30% of responses were unfavorable to the composition.

[0572] Example No. 12 - Formulation No. 4 of a powdery cosmetic composition according to the invention
