Description

Title of the invention: NEW COSMETIC COMPOSITIONS, THEIR PREPARATION PROCESS AND THEIR USE FIELD OF THE INVENTION

[0001] 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. PREVIOUS ART

[0002] 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.

[0003] In 1888, the American brand "Mum®" is said to have created the first antibacterial deodorant. This product was a zinc oxide-based paste applied under the armpits. Other products followed and were distributed in different ways, including powders, liquids, creams, sticks, squeeze bottles, roll-ons, aerosols and pumps, with different forms becoming more or less popular over time. Among their ingredients, aluminum salts quickly established themselves as an active element until they were called into question (risk of cancer, etc.).

[0004] The same fate has been reserved for 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 sought. BRIEF OVERVIEW

[0005] To meet current needs and provide the ideal deodorant, the inventor has formulated a new cosmetic composition in powder form. Also, one of the primary aims of the invention is to provide this new cosmetic composition in powder form. worm 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 allowing its application. DETAILED DESCRIPTION

[0006] According to a first aspect, the subject of the invention is a pulverulent cosmetic composition consisting of or comprising: • an oil, in oily form; • zinc, in powder form; • a powder adhesion agent, in powder form; • an antioxidant, in powder or liquid form, or in paste form; • a prebiotic, in powder form, and / or a probiotic, in the form of powder; and • a deodorant active ingredient.

[0007] Surprisingly, by formulating the powdery cosmetic composition as described above (cosmetic composition in powder form as described above), which is cold-manufactured and is in particular free of preservatives and / or water, the inventor has developed the ideal deodorant in powder form, effective, with a mattifying effect, and which does not moisten the armpits and does not stain clothing once the product is applied.

[0008] Note that the powdery cosmetic composition as described above is not an antiperspirant and / or antiperspirant composition.

In particular, the subject of the invention is the pulverulent cosmetic composition as described above, in which the total amount of said oil is 1% by mass relative to the total mass of said pulverulent cosmetic composition.

[0013] According to another embodiment, the subject of the invention is the powdery cosmetic composition as described above, said zinc being zinc PCA and / or a zinc salt. The invention can therefore use zinc PCA, or a zinc salt (e.g. zinc gluconate, zinc bisglycinate, zinc citrate, zinc sulfate, zinc acetate, zinc pyrophosphate, etc.), or a mixture of zinc PCA and a zinc salt. In particular, the subject of the invention is the powdery cosmetic composition as described above, said zinc being zinc PCA, which is a zinc salt of pyrrolidone carboxylic acid which is marketed for example under the name Zincidone® sold by Solabia.

[0014] According to another embodiment, the subject of the invention is the pulverulent cosmetic composition as described above, in which the total amount of said zinc is from 0.1% to 1% (in particular from 0.3% to 0.7%) by mass relative to the total mass of said pulverulent cosmetic composition, and is in particular 0.5%. In particular, the subject of the invention is the pulverulent 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 pulverulent cosmetic composition.

[0015] 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.

[0016] in particular said adhesion agent being corn starch and / or maltodextrin powder.

[0017] 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.

[0018] 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 55% to 60% (in particular from 57% to 58%) by mass relative to the total mass of said powdery cosmetic composition. In particular, the subject of the invention is the powdery cosmetic composition as described above, in which: • the total quantity of said corn starch is from 55% to 60% (in particular from 57% to 58%) by mass relative to the total mass of said pulverulent cosmetic composition, and is in particular 57.5%; and / or • said probiotic is mixed with one of said powder adhesion agents, in particular maltodextrin powder, the total quantity of said “probiotic / powder adhesion agent” mixture is from 0.1% to 0.5% (in particular from 0.2% to 0.4%) by mass relative to the total mass of said powdery cosmetic composition, and is in particular 0.3%.

[0019] In particular, the invention also relates to the powdery cosmetic composition as described above, in which: • the total quantity of said corn starch is from 55% to 60% (in particular from 57% to 58%) by mass relative to the total mass of said powdery cosmetic composition, and is in particular 57.5%; and • said probiotic is mixed with one of said powder adhesion agents, in particular maltodextrin powder, the total quantity of said “probiotic / powder adhesion agent” mixture is from 0.1% to 0.5% (in particular from 0.2% to 0.4%) by mass relative to the total mass of said powdery cosmetic composition, and is in particular 0.3%.

[0020] The term “antioxidant” designates substances used to prevent the rancidity of said oil, which is caused by the oxidation of vegetable oils and butters in 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 to determine the oxidative stability of lipids: • 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. • 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). • 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.

[0021] Advantageously, the invention relates to a powdery cosmetic composition as described above, said powdery cosmetic composition exhibiting an absence of rancidity of the oil.

[0022] 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 subject of the invention is therefore the powdery cosmetic composition as described above, said antioxidant being chosen from: a tocopherol, a mixture of tocopherols (e.g. Covi-ox® T 90 C), ascorbic acid (vitamin C), an ascorbic acid derivative (e.g. ascorbyl glucoside) and a mixture thereof,

[0023] in particular said antioxidant being a tocopherol, a mixture of tocopherols (eg Covi-ox® T 90 C) or vitamin E.

[0024] According to another embodiment, the invention relates to the composition 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.

[0025] 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.

[0111] Granulometric Distribution: Malvern Instruments - Mastersizer 3000

[0112] Dry sample preparer: Malvern Instruments - Aéro S

[0113] Laser diffraction measures particle size distributions by measuring the angular variation in the intensity of scattered light as a laser beam passes through a sample of dispersed particles. Large particles scatter the light at small angles to the laser beam and small particles scatter light at larger angles. The data relating to the scattered intensity as a function of angle are analyzed to calculate the size of the particles that created the diffraction pattern using Mie theory. The particle size is represented by the diameter of the equivalent sphere, having the same volume as the particle. The measurements carried out in Laser Granulometry are inspired by the ISO 13320:2009 standard. The analyses were carried out in triplicate. Analysis parameter Dry route

[0125] Example No. 3 - Measurement of water activity (Aw) METHOD OF OPERATION Device Description

[0126] The HygroPahn AW 1 is a portable device for measuring 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. Carrying out the test

[0127] Fill the container to the correct level and do not put the lid on.

[0128] Place the sample in the cuvette.

[0129] Place the HygroClip AW-DIO sensor on the bowl.

[0130] Connect the HygroClip AW-DIO sensor to the HygroPalm AW 1 and switch on the device.

[0131] The device has been programmed to AwQuick mode. To change the mode: • Press MENU • Then, press ENTER, • Select the desired mode using the arrows, • Validate by pressing ENTER 3 times. • Return to the main screen.

[0132] To start the measurement, press ENTER.

[0133] The red LED on the HygroClip AW-DIO sensor is flashing during measurement. If the LED is not flashing, check the sensor connection.

[0134] The humidity trend display appears after 60 seconds. Two arrows signify stable temperature and humidity values. When the equilibrium state is reached, the device has frozen the display and two black rectangles then indicate the end of the measurement.

[0135] Repeat the measurement 2 more times and take the average of the three measurements.

[0136] Enter the result.

[0137] Precautions to take for sampling:

[0138] The measurement of water activity must be carried out in a room at stable temperature.

[0139] Do not place the appliance next to a heater, a water pipe or a open window.

[0140] The samples must be in the same climatic conditions as the sensor. It will therefore be necessary to respect an adaptation time to the ambient temperature before taking a measurement.

[0141] Do not take measurements just after manufacturing

[0142] Example No. 4 - Measurement of (apparent) density and tapped density METHOD OF OPERATION Setting up and switching on the device

[0143] 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).

[0144] The device is supplied with 2 graduated cylinders, one of 100 mL and the other of 250 mL. Sample preparation

[0145] The material used must be perfectly dry before use.

[0146] Insert 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.

[0147] Carrying out measurements of packed and unpacked densities

[0148] Unpacked density or apparent density

[0149] 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 mass volume of the sample. The density is calculated by dividing this value by the mass volume of water (i.e. 1 g / mL at room temperature [20°C]).

[0150] [Math.l] unpacked density - powder mass Q?) volume read (mL)

[0151] Packed density

[0152] The measurement of the packed density is carried out with the test tube filled to 230 mL (the same as for the unpacked density).

[0153] Place the test tube on the support and fix it with the black ring, by rotating it.

[0154] Place this assembly on the device.

[0155] A support may be used for the placement of the test piece. Its presence defines the proposed method for carrying out the measurement (see below).

[0156] Press the button to enter the menu.

[0157] Turn the dial to go to “Method” and press to validate. • If the support has been placed, only the USP2 method can be used (example above). • In the absence of support, both methods USP1 and USP2 are available.

[0158] The 2 methods differ in the speed of the strokes: 300 strokes / min for USP1 and 250 strokes / min for USP2.

[0159] A “User” method can also be chosen and allows the method (number of moves) to be manually defined.

[0160] Validate the method by pressing the button. The screen displays the method details. Go to the bottom of the screen with the wheel and press to validate "Save and exit".

[0161] 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”.

[0162] When validating, a message appears to check the presence of the support with the test piece. Validate “Start test”.

[0163] 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.

[0164] Using the example of the USP2 method, the one that was implemented, it is necessary to enter the values read on the test piece after the series of: 10 shots, 490 shots, 750 shots and 1,250 shots.

[0165] After these series, restart 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 measure

[0166] At the end of the measurement, the results appear on the screen: • Reminder of the method • Tap density and untapped density. • Compressibility index providing information on the powder's ability to compact (“compressibility index”) • Hausner index (“Hausner ratio”): this is an adimensional quantity equal to the ratio of the packed density to the unpacked density, which provides information on the flow properties of the powder. • Reminder of volumes read after each series of shots. Example No. 5 - pH Measurement

[0167] 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.
