Description

Title of the invention: Process for coloring and / or lightening keratin fibers

[0001] The invention relates to a process for coloring and / or lightening keratin fibers, preferably hair, in which a coloring and / or lightening composition is applied to the keratin fibers by hand.

[0002] For a long time, many people have been looking to change the color of their hair, and in particular to hide their gray hair.

[0003] It is known to dye keratin fibers, in particular human keratin fibers such as hair, to obtain so-called permanent colorations with dye compositions containing oxidation dye precursors, in particular oxidation bases, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols or heterocyclic compounds such as pyrazoles, pyrazolinones or pyrazolo-pyridines. These oxidation bases are colorless or weakly colored compounds which, combined with oxidizing products, can give rise to colored compounds by an oxidative condensation process.

[0004] It is also possible to vary the shades obtained with these oxidation bases by combining them with couplers or color modifiers. The variety of molecules used in the oxidation bases and couplers allows a rich palette of colors to be obtained.

[0005] The permanent coloring processes therefore consist of using, with the dye composition containing the oxidation dyes, an aqueous composition comprising at least one oxidizing agent such as hydrogen peroxide, under alkaline pH conditions in the vast majority of cases. The alkaline agent conventionally used is ammonia or can be chosen from other alkaline agents, such as alkaline amines.

[0006] The compositions containing the dyes and the oxidizing compositions are packaged separately and must be mixed just before application to the hair.

[0007] Generally, oxidation coloring products intended for self-coloring hair consist of kits comprising, on the one hand, a dispenser bottle containing the oxidizing composition and, on the other hand, a tube containing the composition comprising the colorants. The bottle and the tube are packaged in a box which sometimes also contains a post-coloring treatment and accessories such as gloves.

[0008] At the time of use, the user must empty the tube into the dispenser bottle. to mix the oxidizing composition with the coloring composition. The bottle must then be shaken to obtain a homogeneous mixture. The user can then distribute the ready-to-use composition onto their hair using the dispenser bottle.

[0009] The application technique is not simple and sometimes results in uneven coloring. The user often feels as though they have not mastered the mixture.

[0010] Consumers are also looking for more environmentally friendly coloring and / or lightening products, particularly those based on ingredients of natural origin, without compromising on the dyeing and / or lightening properties obtained, and which limit the use of plastic materials.

[0011] Furthermore, coloring and / or lightening compositions often comprise raw materials for which regulatory conditions are increasingly strict. It is therefore necessary to develop coloring and / or lightening processes which use compositions comprising alternative compounds.

[0012] Thus, there is a real need to provide a process for coloring and / or lightening keratin fibers, in particular human keratin fibers such as hair, which does not have the drawbacks mentioned above, and in particular is pleasant to use, which allows for easier mixing and application, which is more environmentally friendly, without compromising the final coloring and / or lightening result.

[0013] These and other aims are achieved by the present invention which therefore relates to a process for coloring and / or lightening keratin fibers, preferably hair, comprising the following steps, in order: a) pouring, simultaneously or successively, a coloring and / or lightening composition (A) comprising one or more alkaline agents and / or one or more coloring agents and an oxidizing composition (B) comprising one or more chemical oxidants into a pot having a base of internal surface area S; b) mixing the two compositions (A) and (B) in the pot in order to obtain a composition (C) occupying a volume V in the pot, the V / S ratio being between 8 and 30 mm; c) take composition (C) from the pot by hand; d) applying composition (C) by hand to the keratin fibers; e) optionally knead the keratin fibers with your hand; f) after a pause time ranging from 1 minute to 1 hour, preferably from 10 to 50 minutes, preferably from 15 to 45 minutes, rinse the keratin fibers.

[0014] According to a preferred embodiment, the method according to the invention is a method of coloring of keratin fibers, especially hair.

[0015] For the purposes of the present invention, the term “taking up or applying by hand” means taking up or applying a composition directly with the hand, without an application utensil such as a brush, a brush, or even without a dispensing tip. The hand is preferably covered with a glove.

[0016] The method according to the invention allows for easy, pleasant application, similar to applying a hair treatment, using hand movements. The application is also precise and localized.

[0017] Furthermore, mixing the compositions is simple and safe. The configuration of the pot makes it easy to mix the compositions, limiting the risk of overflow while allowing easy access to the bottom of the pot for manually removing the composition to be applied.

[0018] The steps of mixing and collecting the composition obtained are thus facilitated, which allows for a homogeneous application which leads to good dyeing results.

[0019] Furthermore, the compositions used in the process according to the invention have good qualities of use, in particular a creamy, melting texture, allowing rapid and easy mixing, easy application by hand with limited risks of dripping, and easy and homogeneous distribution over the entire head of hair.

[0020] Furthermore, when used to color hair, the method according to the invention makes it possible to produce chromatic, powerful, intense and non-selective colorations, that is to say colorations which are homogeneous along the fiber. It also makes it possible to cover depigmented keratin fibers, such as white hair, particularly well.

[0021] In addition, the pot has an interior volume allowing it to accommodate all the constituents necessary for the coloring and / or lightening process. The pot can thus be used both to separately contain the compositions to be mixed (A) and (B) and to serve as a container for mixing these compositions, thus limiting waste.

[0022] Other objects, characteristics, aspects and advantages of the invention will appear even more clearly on reading the description and the examples which follow.

[0250] The above additives may generally be present in an amount of between 0 and 20% by weight for each of them, relative to the total weight of the composition (A).

[0251] Preferably, composition (A) does not comprise chemical oxidizing agents. 2. Oxidizing composition (B)

[0252] The oxidizing composition (B) comprises one or more chemical oxidizing agents.

[0253] By “chemical oxidizing agent” according to the invention, we mean an oxidizing agent other than than the oxygen in the air.

[0254] More particularly, the chemical oxidizing agent(s) are chosen from hydrogen peroxide, urea peroxide, alkali metal bromates or ferricyanides, peroxygenated salts such as, for example, persulfates, perborates, peracids and their precursors and alkali or alkaline-earth metal percarbonates and their mixtures. Preferably, the oxidizing agent is chosen from hydrogen peroxide.

[0255] The oxidizing composition (B) is preferably an aqueous composition. In particular, it comprises more than 5% by weight of water, preferably more than 10% by weight of water, and even more advantageously more than 20% by weight of water.

[0256] It may also comprise one or more organic solvents chosen from those listed above; the latter representing more particularly, when present, from 1 to 40% by weight relative to the weight of the oxidizing composition, and preferably from 5 to 30% by weight.

[0257] The oxidizing composition (B) also preferably comprises one or more acidifying agents. Among the acidifying agents, mention may be made, by way of example, of mineral or organic acids such as hydrochloric acid, orthophosphoric acid, sulfuric acid, carboxylic acids such as acetic acid, tartaric acid, citric acid, lactic acid, sulfonic acids.

[0258] In addition, the oxidizing composition (B) may comprise fatty substances such as those described above, preferably chosen from fatty alcohols, liquid hydrocarbons comprising more than 16 carbon atoms and their mixtures, surfactants, polymers.

[0259] Usually, the pH of the oxidizing composition, when aqueous, is less than 7.

[0260] Preferably, the oxidizing composition (B) comprises hydrogen peroxide as oxidizing agent, the concentration of which varies, more particularly, from 0.1 to 50%, more particularly between 0.5 and 20%, and even more preferably between 1 and 15% by weight relative to the weight of the oxidizing composition (B).

[0261] Composition (A) and composition (B) are preferably mixed in a composition (A) / composition (B) weight ratio ranging from 0.5 to 2, preferably from 0.5 to 1.5, better still from 0.5 to 1.

[0262] The ready-to-use composition (C) resulting from the mixture of the coloring and / or lightening composition (A) and the oxidizing composition (B) preferably has a viscosity greater than or equal to 3 Pa.s, preferably greater than or equal to 3.2 Pa.s, better still, greater than or equal to 3.5 Pa.s at a temperature of 25°C, at atmospheric pressure and at a shear rate of 1 s 1 (measurable for example with a Haake RS600 Rheometer). Preferably, the ready-to-use composition (C) has a viscosity ranging from 3 to 500 Pa.s, more preferably ranging from 3.2 to 300 Pa.s, and even more preferably ranging from 3.5 to 200 Pa.s at a temperature of 25°C, at atmospheric pressure and at a shear rate of 1 s 1 (measurable for example with a Haake RS600 Rheometer).

[0264] The threshold stress is determined by stress scanning at 25°C. A Thermo Haake RS600 rheometer with imposed stress in sandblasted cone-plate geometry is used. The temperature is regulated by a Peltier effect plane and an anti-evaporation device (solvent trap filled with water for measurements at 25°C).

[0265] A logarithmic stress increase of 0.5 to 500 Pa is carried out over a period of 3 minutes. Two adjustment lines corresponding to the stationary regimes (solid and liquid behaviors) are plotted on the curve representing the deformation as a function of the stress (logarithmic coordinates). The intersection of these two lines provides the value of the threshold stress. 3. Pot

[0266] The pot used in the process according to the invention to receive the mixture of compositions (A) and (B) and obtain the ready-to-use composition (C) has an internal surface area base S.

[0267] The pot serves both to separately contain the compositions to be mixed (A) and (B) and to mix them.

[0268] The volume V occupied by the ready-to-use composition (C) resulting from the mixture of composition (A) and oxidizing composition (B) is preferably between 70 and 150 mL, more preferably between 95 and 125 mL.

[0269] The V / S ratio may be between 8 and 30 mm, preferably between 13 and 20 mm, more preferably between 15.0 and 18.5 mm. The V / S ratio corresponds substantially to the height of the mixture.

[0270] The pot is preferably of circular section, with an internal diameter D preferably between 80 and 105 mm, better between 90 and 95 mm. By "internal diameter" it is necessary to understand when the section is non-circular the equivalent diameter of a fictitious circular section of the same area.

[0271] It is also possible to use a pot whose base is not circular, in particular a pot with a substantially rectangular base. The rectangular base is, for example, 90mm x 70mm in size, which is substantially equivalent to a circular base with a diameter of 90 mm.

[0272] The pot preferably has an internal height not exceeding 125 mm, better still not exceeding 110 mm. The internal height may in particular be between 50 and 110 mm.

[0273] The dimensions of the pot make it possible on the one hand to limit the risk of overflow and on the other hand guarantee a sufficient level of product in the pot to facilitate its homogenization and manual access to the bottom of the pot for removing the product.

[0274] In addition, such a pot has an interior volume allowing all the constituents of the assembly to be housed with a good filling rate of the pot, which avoids having to provide specific means of wedging the different constituents.

[0275] The pot contains in particular the compositions to be mixed to obtain the ready-to-use composition (C).

[0276] The compositions (A) and (B) to be mixed are packaged separately in a container, which may be a sachet, a tube or a bottle. Preferably, each composition (A) and (B) is packaged in a sachet.

[0277] Each composition (A) and (B) may be present in the pot in a volume ranging from 40 to 75 mL.

[0278] The pot may also contain other elements useful in the coloring and / or lightening process of the invention.

[0279] It may, for example, contain gloves to protect the user's hands during application.

[0280] It may optionally contain a spatula for stirring the mixture of compositions (A) and (B).

[0281] It may also contain one or more other compositions to be applied after coloring and / or lightening, for example a care composition or a shampoo.

[0282] It may also contain instructions for use.

[0283] The pot may include a lid arranged to be fixed thereon so as to enclose the various constituents initially contained in the pot.

[0284] The material of the pot can be any cardboard suitable for containing the mixture for the time necessary for application. The lid can also be made of cardboard. The spatula can be made of wood, compressed palm or banana leaf, or even folded cardboard of the same nature as the pot, if the latter is made of cardboard.

[0285] The use of cardboard reduces the amount of plastic material, and the pot can be single-use, which avoids the need for extensive, water-consuming cleaning.

[0286] The invention may be better understood by reading the detailed description which follows, of non-limiting examples of implementation of the invention, and by examining the attached drawing, in which:

[0287] [Fig-1] represents the pot and the lid;

[0288] [Fig.2] represents in isolation, in longitudinal section, the pot containing the mixture of compositions.

[0289] According to the particular embodiment illustrated in figures 1 and 2, the pot 10 has a body 13 of generally truncated cone shape.

[0290] The pot 10 may include an attached bottom 12, having a cross section in U turned over, glued by its periphery to the body 13.

[0291] The diameter D is that measured inside the pot at its base, that is to say at the level of the wall of the added bottom.

[0292] The internal height H of the pot corresponds to the distance between the bottom 12 and the plane resting on the upper edge of the pot 10.

[0293] The internal diameter D of the base of the pot 10 is for example between 80 and 105 mm, i.e. an internal area S of the base approximately between 50 and 87 cm2.

[0294] The assembly comprises a cover 20 for closing the pot 10.

[0295] The pot is made of a cardboard material. The attached base is also made of a cardboard material, as is the lid 20.

[0296] Compositions (A) and (B) form, after being poured into the pot, a total volume V of ready-to-use composition (C).

[0297] This volume V occupies a height H3 in the pot 10, as illustrated in [Fig.2].

[0298] When mixing compositions (A) and (B) while stirring with a spatula, a small volume v of mixture typically wets a height H2 of the pot wall above the level of the mixture at rest.

[0299] The remaining height H1 is such that the internal height H=H1+H2+H3 is between 50 and 110 mm.

[0300] For example, H2 is between 10 and 50 mm and H1 is between 32 and 60 mm.

[0301] Each composition (A) and (B) is packaged in a sachet, which may be a flat sachet.

[0302] The pot 10 initially contains the sachets containing the compositions (A) and (B). It also contains a pair of gloves, a mixing spatula, a third sachet containing a hair care composition. It may also contain instructions for use. Process

[0303] According to the coloring and / or lightening process of the invention, the user pours in step a), simultaneously or successively, a coloring and / or lightening composition (A) as described previously and an oxidizing composition (B) as described previously into a pot as described previously, having a base of internal area S.

[0304] Preferably, the user pours the oxidizing composition (B) into the pot before the composition (A) in step a).

[0305] He then mixes the two compositions (A) and (B) in the pot in order to obtain a composition (C), ready-to-use, occupying a volume V in the pot, the ratio V / S being between 8 and 30 mm.

[0306] The step of mixing compositions (A) and (B) is preferably carried out with a spatula. Alternatively, it is possible to do without a spatula and mix the two compositions directly with the hand.

[0307] The user then takes the composition (C) from the pot by hand and applies it by hand to the hair. These steps can be repeated between one and ten times to apply the necessary amount of composition (C) to the hair so that all the hair on a head is covered with composition (C).

[0308] According to a preferred embodiment, the user takes by hand a small quantity of composition (C), preferably a quantity corresponding to a nut, and applies it to the hair. He repeats this step several times until all the hair on the head is covered with composition (C).

[0309] According to a preferred embodiment, in step d), the user first applies the composition (C) to the roots of the hair on the head, preferably on either side of a previously defined parting, preferably on the upper part of the head. The user can repeat this step by successively applying on either side of several partings formed on the upper part of the head until all the roots of the upper part of the head and the temples are covered with composition (C).

[0310] Preferably, after applying the composition (C) to all of the roots of the upper part of the head and the temples, the user ties the lengths of the hair of the upper part of the head, so as to clear the back part of the head. If the hair is sufficiently long, the user preferably forms a bun with the hair of the upper part of the head. Then, the user applies the composition (C) to the roots of the back part of the head.

[0311] Preferably, the user spreads by hand the composition (C) present on the roots over the entire length of the hair. When the user has previously tied up the hair on the upper part of the head, the user unties the hair, in particular the bun, before spreading by hand the composition (C) present on the roots over the entire length of the hair.

[0312] After applying composition (C) to the hair, the user may optionally knead the hair with the hand.

[0313] After a pause time ranging from 1 minute to 1 hour, preferably from 10 to 50 minutes, preferably from 15 to 45 minutes, the hair is rinsed.

[0314] Preferably, when compositions (A) and (B) are initially contained in containers, preferably sachets, packaged in the pot, the user must first remove the containers from the pot before opening them to pour their contents into the pot.

[0315] Preferably, when the pot contains other components such as protective gloves, a mixing spatula, another container containing another composition such as a hair care product, instructions for use, etc., the user must of course remove them from the pot before pouring in compositions (A) and (B).

[0316] The ready-to-use composition (C) can be applied by hand to dry or damp hair.

[0317] At the end of the treatment, after rinsing, the hair optionally undergoes a step of washing g) the hair with a detergent composition (D) followed by a step of rinsing with water, optionally followed by a step of wringing h) the keratin fibers.

[0318] A hair care composition (E) may optionally be applied after rinsing the hair, optionally followed by another rinsing step.

[0319] At the end of treatment, the hair can be dried or left to dry.

[0320] Preferably, the user covers his hands with protective gloves before taking the composition by hand in step c), preferably before step b) of mixing, or preferably before pouring in step a) the compositions (A) and (B) into the pot.

[0321] Preferably, the user has his hands covered with protective gloves at least until step f) of rinsing the hair.

[0322] The following examples serve to illustrate the invention without, however, being limiting in nature. Examples

[0323] In the following examples, all quantities are indicated as a percentage by mass of active ingredient (AI) relative to the total weight of the composition (unless otherwise stated). Compositions

[0327] A pot as described above and illustrated in Figures 1 and 2 contains a first sachet containing 40 g of coloring composition Al and a second sachet containing 60 g of oxidizing composition B. The pot also contains instructions for use, a pair of gloves, a wooden spatula and a third sachet containing a hair care composition.

[0328] The user extracts from the pot all the elements initially contained therein.

[0329] He puts on protective gloves before pouring the entire contents of the sachet containing the oxidizing composition B and then the contents of the sachet containing the coloring composition Al into the pot.

[0330] He then mixes the two compositions A1 and B using the spatula so as to obtain a ready-to-use composition C occupying a volume of approximately 100 ml in the pot. Mixing is easy.

[0331] He then takes a small amount of composition (C) from the pot by hand and applies it by hand to his dry hair.

[0332] He repeats these steps of taking and applying by hand so as to apply the necessary quantity of composition (C) to the hair.

[0333] Hand picking up the coloring mixture is easy until the end of the pot. Hand application to the hair is easy and allows good localization of the coloring mixture in the desired areas, without dripping.

[0334] He kneads his hair with his hand so as to distribute the composition over the whole head of hair.

[0335] After a 30-minute pause, the user rinses their hair with water. They then let their hair dry.

[0336] A powerful hair coloring is obtained.

[0337] According to two other embodiments, the pot contains a sachet containing the coloring composition A2 instead of the composition A1, or the composition A3. The same method as that described in the first example is implemented.

[0338] Compositions A2 and A3 also lead to powerful hair colorings.
