Definitions

  • the invention relates to a composition for dyeing keratin fibres, comprising i) at least 1 % and preferably at least 5% of red henna (Lawsonia inermis, alba) powder and/or of powder of indigo-producing plant(s), ii) at least one oil, iii) optionally at least one surfactant, and iv) water or an aqueous phase, preferably water, it being understood that the ingredients ii), iii) and iv) are predispersed together and the ingredient(s) i) and the said predispersion are then mixed together; the invention also relates to a composition comprising the said composition and a supplement of water or of aqueous phase, the process for dyeing keratin fibres using the said compositions, and to the use of the said compositions for dyeing keratin fibres.
  • the first known as oxidation dyeing or permanent dyeing, consists in using one or more oxidation dye precursors, more particularly one or more oxidation bases optionally combined with one or more couplers.
  • Oxidation bases are usually selected from ortho- or para-phenylenediamines, ortho- or para-aminophenols, and heterocyclic compounds. These oxidation bases are colourless or weakly coloured compounds, which, when combined with oxidizing products, can give rise via a process of oxidative condensation to coloured species, which remain trapped within the fibre.
  • the shades obtained with these oxidation bases are often varied by combining them with one or more couplers, these couplers being chosen especially from aromatic meta- diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds, such as indole compounds.
  • the second dyeing method comprises the application of direct dyes, which are coloured and colouring molecules that have affinity for fibres. Given the nature of the molecules used, they tend rather to remain on the surface of the fibre and penetrate relatively little into the fibre, when compared with the small molecules of oxidation dye precursors.
  • the main advantages of this type of dyeing are that it does not require any oxidizing agent, which limits the degradation of the fibres, and that it does not use any dyes that have particular reactivity, resulting in limitation of the intolerance risks.
  • the first hair dyes were semi-permanent.
  • One of the most well known natural dyes is that derived from the henna plant. Henna is still be used in feminine beauty enhancement for colouring the hair or the nails, or for dyeing leather, silk and wool, etc. It is also be used traditionally for various important events, celebrations and beliefs.
  • Red henna consists of leaves of shrubs of the genus Lawsonia from the family of Lythraceae, which is based on the principle of dyeing with the active agent lawsone: 2- hydroxy-1 ,4-naphthoquinone.
  • This dye affords an orange-red coloration on grey hair, and a "warm” i.e. coppery to red colour on chestnut-brown hair.
  • the dyeing process using henna is difficult to perform.
  • a kind of "paste” (often referred to as a "poultice") is first made from ground or powdered henna leaves, which is then diluted at the time of use with warm water, and the said paste is then applied to the keratin fibres.
  • Indigo is derived from indican and may be prepared from various plants known as indigo-producing plants such as Indigofera tinctoria, Indigo suffruticosa, Isatis tinctoria, etc. (see Kirk-Othmer Encyclopedia of Chemical Technology, updated on 17/04/2009, DOI: 10.1002/0471238961.0425051903150618.a01.pub2).
  • the indigo-producing plants are generally chopped and soaked in hot water, heated, fermented and oxidized in the open air to liberate the purple-blue coloured indigo (see Chem. Rev. 201 1 , 111 , 2537-2561 , pp. 2537-2561 ).
  • Indigo is the result of the fermentation and then oxidization of indican (glycosyl precursor).
  • the indigo molecule is insoluble in water.
  • the problem is that dyeing using the indigo plant is difficult because the uptake of the colour into the keratin fibres is very poor. This dye affords a blue coloration on grey hair, and a "cold” colour of ash to violet colour on chestnut-brown hair.
  • the dyeing process using indigo leaves is difficult to perform.
  • a kind of "paste" (often referred so as a poultice) is first made from ground or powdered leaves of indigo plant (or Indian indigo or dyer's indigo) or dyer's pastel (Isatis tinctoria), which needs to have been fermented, and which is then diluted at the time of use with warm water, and the said paste is then applied to the keratin fibres.
  • the leave-on time is very long with henna or indigo. It may vary from several tens of minutes to several hours (overnight) depending on the desired intensity, with no ability to control the result. The result varies as a function of the fibres to be dyed and of the indigo or henna raw material used.
  • metal salts as mordants for improving the coloration of henna ⁇ Ullmann's Encyclopedia, 2006 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim 10.1002/14356007.a12 571 .pub2 and US 2010/03133362). It is also known practice to use metal salts to improve the dyeing of indigo (vat dyes - see Chem. Rev. 201 1 , 111 , 2537- 2561 , pp. 2537-2561 ). The use of these agents requires great know-how, multiplies the steps of the process, is not always friendly towards the integrity of the fibre (cosmetically unfriendly) and may disrupt subsequent cosmetic treatments.
  • Another solution is to use dye powder, optionally in the presence of excipients in fine powder form (DE 195 48 291 ).
  • these powders are conditioned in sachets or blister packs (DE 101 31 385). If the packaging of the said powder happens to become broken, a large amount of raw material is lost into the air and cannot be recovered. Added to the problem of the loss of raw material is that linked to the fineness of the particles for users.
  • the particles in the atmosphere can cause respiratory problems or allergies such as rhinitis for the users, sellers of extracts or natural dyeing professionals (Allergy, J. Scibilia, E. Galdi, G. Biscaldi, G. Moscato, 52, 231 -232, (1997)).
  • henna leaf powder for example, optionally in the presence of excipients in powder form (DE 299 02 432).
  • these powders are conditioned in sachets or blister packs. If the packaging of the dye powder happens to become broken, a large amount of raw material is lost into the air and cannot be recovered.
  • Added to the problem of the loss of raw material is that linked to the pulverulence for users as indicated previously. Specifically, in the form of fine particles, henna or indigo becomes suspended in the atmosphere and can cause respiratory problems or allergies such as rhinitis for the users, sellers of extracts or natural dyeing professionals (Allergy, J. Scibilia, E. Galdi, G. Biscaldi, G. Moscato, 52, 231 - 232, (1997)).

  • composition of the invention may be used subsequently, optionally after storage with or without subsequent addition of water.
  • a subject of the invention is also a process for preparing the preceding composition, which consists in preparing a predispersion comprising ingredients ii), iii) and iv) of the composition and then in mixing the ingredient(s) i) with the said predispersion.
  • a subject of the invention is also a process for dyeing keratin fibres, especially the hair, using the composition as defined previously.
  • compositions and the process using the composition according to the invention have the advantage of dyeing keratin fibres, especially human keratin fibres, with strong, chromatic colorations that are resistant to washing, perspiration, sebum and light, and that are moreover long-lasting, without impairing the said fibres. Furthermore, the colorations obtained using the composition and the process give uniform colours from the root to the end of a fibre (little coloration selectivity). Furthermore, the application of the composition does not give off any raw material dust (dust-free). The composition is easy to use, in total safety and with no risk of staining. In addition, the composition and the active agent(s) (henna and/or indigo natural dyes) remain stable on storage.

Description

COMPOSITION BASED ON HENNA OR INDIGO POWDER WITH A PREDISPERSION OF OIL, AND HAIR DYEING PROCESS USING THIS COMPOSITION
The invention relates to a composition for dyeing keratin fibres, comprising i) at least 1 % and preferably at least 5% of red henna (Lawsonia inermis, alba) powder and/or of powder of indigo-producing plant(s), ii) at least one oil, iii) optionally at least one surfactant, and iv) water or an aqueous phase, preferably water, it being understood that the ingredients ii), iii) and iv) are predispersed together and the ingredient(s) i) and the said predispersion are then mixed together; the invention also relates to a composition comprising the said composition and a supplement of water or of aqueous phase, the process for dyeing keratin fibres using the said compositions, and to the use of the said compositions for dyeing keratin fibres.
Two major methods for dyeing human keratin fibers, and in particular the hair, are known.
The first, known as oxidation dyeing or permanent dyeing, consists in using one or more oxidation dye precursors, more particularly one or more oxidation bases optionally combined with one or more couplers.
Oxidation bases are usually selected from ortho- or para-phenylenediamines, ortho- or para-aminophenols, and heterocyclic compounds. These oxidation bases are colourless or weakly coloured compounds, which, when combined with oxidizing products, can give rise via a process of oxidative condensation to coloured species, which remain trapped within the fibre.
The shades obtained with these oxidation bases are often varied by combining them with one or more couplers, these couplers being chosen especially from aromatic meta- diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds, such as indole compounds.
The variety of molecules used as oxidation bases and couplers allows a wide range of colours to be obtained.
The second dyeing method, known as direct dyeing or semipermanent dyeing, comprises the application of direct dyes, which are coloured and colouring molecules that have affinity for fibres. Given the nature of the molecules used, they tend rather to remain on the surface of the fibre and penetrate relatively little into the fibre, when compared with the small molecules of oxidation dye precursors. The main advantages of this type of dyeing are that it does not require any oxidizing agent, which limits the degradation of the fibres, and that it does not use any dyes that have particular reactivity, resulting in limitation of the intolerance risks.
The first hair dyes were semi-permanent. One of the most well known natural dyes is that derived from the henna plant. Henna is still be used in feminine beauty enhancement for colouring the hair or the nails, or for dyeing leather, silk and wool, etc. It is also be used traditionally for various important events, celebrations and beliefs. Red henna consists of leaves of shrubs of the genus Lawsonia from the family of Lythraceae, which is based on the principle of dyeing with the active agent lawsone: 2- hydroxy-1 ,4-naphthoquinone. Lawsone [83-72-7] (CI Natural Orange 6; CI 75420), also known as isojuglone, may be found in henna shrubs (Lawsonia alba, Lawsonia inermis) ("Dyes, Natural", Kirk-Othmer Encyclopedia of Chemical Technology, "Henna" Encyclopedia Britannica).
This dye affords an orange-red coloration on grey hair, and a "warm" i.e. coppery to red colour on chestnut-brown hair. The dyeing process using henna is difficult to perform. A kind of "paste" (often referred to as a "poultice") is first made from ground or powdered henna leaves, which is then diluted at the time of use with warm water, and the said paste is then applied to the keratin fibres.
However, this process using the said paste has drawbacks. During the preparation and application of the composition to keratin fibres, it is not always possible to obtain satisfactory impregnation due to the poor consistency of the composition obtained from the coarsely ground powder. Furthermore, it is very difficult to hope to reproduce shades exactly, since the lawsone content very often varies from one batch to another and between different ground materials.
Another very well-known natural dye is indigo (see Ullmann's Encyclopedia of Industrial Chemistry, Hair preparation, point 5.2.3, 2006 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim; 10.1002/14356007.a12 571.pub2). Indigo continues to be used for feminine beauty by dyeing the hair or the nails, or for dyeing fabrics (jeans), leather, silk, wool, etc. Indigo [482-89-3] is a natural dye, originating especially from the indigo plant, and having the empirical formula: Ci6H10N2O2; and having the structure:
Figure imgf000003_0001
Indigo is derived from indican and may be prepared from various plants known as indigo-producing plants such as Indigofera tinctoria, Indigo suffruticosa, Isatis tinctoria, etc. (see Kirk-Othmer Encyclopedia of Chemical Technology, updated on 17/04/2009, DOI: 10.1002/0471238961.0425051903150618.a01.pub2). The indigo-producing plants are generally chopped and soaked in hot water, heated, fermented and oxidized in the open air to liberate the purple-blue coloured indigo (see Chem. Rev. 201 1 , 111 , 2537-2561 , pp. 2537-2561 ). Indigo is the result of the fermentation and then oxidization of indican (glycosyl precursor). The indigo molecule is insoluble in water.
The problem is that dyeing using the indigo plant is difficult because the uptake of the colour into the keratin fibres is very poor. This dye affords a blue coloration on grey hair, and a "cold" colour of ash to violet colour on chestnut-brown hair. The dyeing process using indigo leaves is difficult to perform. A kind of "paste" (often referred so as a poultice) is first made from ground or powdered leaves of indigo plant (or Indian indigo or dyer's indigo) or dyer's pastel (Isatis tinctoria), which needs to have been fermented, and which is then diluted at the time of use with warm water, and the said paste is then applied to the keratin fibres. However, this process using the said paste has drawbacks. During the preparation and application of the composition to keratin fibres, it is not always possible to obtain satisfactory impregnation due to the poor consistency of the composition obtained from the coarsely ground powder. Furthermore, it is very difficult to hope to reproduce shades exactly, since the indigo content very often varies from one batch to another and between different ground materials.
As much as the colour obtained on chestnut-brown hair has a natural look, grey hair is dyed an unaesthetic and unnatural orange colour with henna or blue colour with indigo ("Hair preparations", Kirk-Othmer Encyclopedia of Chemical Technology, John Wiley & Sons, Inc.). Furthermore, the colorations obtained are not uniform between the root and the end or from one fibre to another (The Science of Hair Care, C. Bouillon, J. Wilkinson, 2d Ed., CRC Press, Taylor & Francis Group; Boca Raton, London, pp. 236-241 (2005)).
Added to this are the risks of staining of clothing and the skin with henna or indigo during the preparation of the "paste" and also during its application to the keratin fibres, since the consistency is very irregular.
In addition, the leave-on time is very long with henna or indigo. It may vary from several tens of minutes to several hours (overnight) depending on the desired intensity, with no ability to control the result. The result varies as a function of the fibres to be dyed and of the indigo or henna raw material used.
It is known practice to use metal salts as mordants for improving the coloration of henna {Ullmann's Encyclopedia, 2006 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim 10.1002/14356007.a12 571 .pub2 and US 2010/03133362). It is also known practice to use metal salts to improve the dyeing of indigo (vat dyes - see Chem. Rev. 201 1 , 111 , 2537- 2561 , pp. 2537-2561 ). The use of these agents requires great know-how, multiplies the steps of the process, is not always friendly towards the integrity of the fibre (cosmetically unfriendly) and may disrupt subsequent cosmetic treatments.
Another solution is to use dye powder, optionally in the presence of excipients in fine powder form (DE 195 48 291 ). Generally, these powders are conditioned in sachets or blister packs (DE 101 31 385). If the packaging of the said powder happens to become broken, a large amount of raw material is lost into the air and cannot be recovered. Added to the problem of the loss of raw material is that linked to the fineness of the particles for users. Specifically, in the form of a suspension, the particles in the atmosphere can cause respiratory problems or allergies such as rhinitis for the users, sellers of extracts or natural dyeing professionals (Allergy, J. Scibilia, E. Galdi, G. Biscaldi, G. Moscato, 52, 231 -232, (1997)).
Another solution for improving the coloration using these natural dyes is to use very finely ground henna leaf powder, for example, optionally in the presence of excipients in powder form (DE 299 02 432). Generally, these powders are conditioned in sachets or blister packs. If the packaging of the dye powder happens to become broken, a large amount of raw material is lost into the air and cannot be recovered. Added to the problem of the loss of raw material is that linked to the pulverulence for users as indicated previously. Specifically, in the form of fine particles, henna or indigo becomes suspended in the atmosphere and can cause respiratory problems or allergies such as rhinitis for the users, sellers of extracts or natural dyeing professionals (Allergy, J. Scibilia, E. Galdi, G. Biscaldi, G. Moscato, 52, 231 - 232, (1997)).
To overcome the problem of the poor dyeing efficacy of natural dyes, it is known practice to "dope" coloration by adding direct dyes that are generally used in direct dyeing, such as nitrobenzene, anthraquinone, nitropyridine, azo, methine, azomethine, xanthene, a pyridine, azine or triarylmethane direct dyes (DE 199 05 707, EP 0 806 199, JP 2010- 0001278). This option has the drawback for natural product users, or for partisans of "natural/bio" products, in that the coloration is partly performed using synthetic dyes. International patent application WO 97/39724 describes hair treatment compositions in solid form and compounds whose viscosity does not exceed 500 mPa.s. The proposed compositions cannot produce rapid or satisfactory colorations. Furthermore, the solid compositions do not always readily break down in water. In addition, the poultices derived from the compositions of the prior art are not always creamy and/or easy to apply.
There is thus a real need to develop dyeing processes that can produce powerful colorations using henna and/or indigo, while at the same time being friendly to the cosmetics of keratin fibres. In particular, there is a need to provide a henna- or indigo-based dyeing product that does not have the drawbacks mentioned above, especially a dust-free product that is easy to store, readily miscible (rapid breakdown) in water, and that can especially produce colorations that are less aggressive to the hair and at the same time that are resistant to external agents (light, bad weather or shampooing), and that are fast and homogeneous, while at the same time remaining powerful and chromatic. This aim is achieved with the present invention, a first subject of which is a composition comprising:
i) at least 1 % by weight and preferably at least 5% by weight of red henna powder and/or of powder of indigo-producing plant(s), relative to the total weight of the composition; ii) at least one oil, preferably of plant origin;
iii) optionally at least one surfactant, preferably a nonionic and/or anionic surfactant; and iv) water or an aqueous phase, preferably water; it being understood that the ingredients ii), iii) and iv) are predispersed together to form a predispersion, and the ingredient(s) (i) are then dispersed in the said predispersion or the said predispersion is dispersed in the said ingredient(s) i).
Preferably, the predispersion comprising the ingredients ii), iii) and iv) is an emulsion of water-in-oil type. More particularly, the predispersion is a microemulsion or even a nanoemulsion, preferably of water-in-oil type.
According to a particular embodiment of the invention, the above composition is a ready-to-use composition, i.e. it may be used as such at the time of use, without requiring supplementary addition of water. It may advantageously be in the form of a poultice.
According to a particular embodiment, the composition of the invention may be used subsequently, optionally after storage with or without subsequent addition of water.
A subject of the invention is also a process for preparing the preceding composition, which consists in preparing a predispersion comprising ingredients ii), iii) and iv) of the composition and then in mixing the ingredient(s) i) with the said predispersion.
A subject of the invention is also a process for dyeing keratin fibres, especially the hair, using the composition as defined previously.
The compositions and the process using the composition according to the invention have the advantage of dyeing keratin fibres, especially human keratin fibres, with strong, chromatic colorations that are resistant to washing, perspiration, sebum and light, and that are moreover long-lasting, without impairing the said fibres. Furthermore, the colorations obtained using the composition and the process give uniform colours from the root to the end of a fibre (little coloration selectivity). Furthermore, the application of the composition does not give off any raw material dust (dust-free). The composition is easy to use, in total safety and with no risk of staining. In addition, the composition and the active agent(s) (henna and/or indigo natural dyes) remain stable on storage. The treated keratin fibres have a very pleasant cosmetic aspect, their integrity is respected.
In addition, the composition or the poultice derived from the composition as defined below of the invention is particularly creamy and/or shows excellent adhesion to the hair.

Predispersion, emulsion, microemulsion and nanoemulsion
The predispersion of the invention uses the ingredients ii) and iv), and optionally iii), as defined below, which are thus predispersed.
The term "predispersed" means that the ingredients ii), iv) and optionally iii) are mixed with iv) water or the aqueous phase of the composition of the invention so as to obtain a "dispersion", which is preferably stable at room temperature and at atmospheric pressure, before being mixed with the ingredient i), and with the optional remainder of water, the said predispersion possibly containing the optional ingredients as described below.
When the predispersion comprises at least one surfactant, it will be referred to as a preemulsion. For the purposes of the present invention, the term "dispersed" means that the solid ingredient (such as the ingredient i)) is distributed in the mixture of ingredients ii), iv) and optionally iii) without being dissolved. For the purposes of the invention, the term "emulsion" means the mixture of a liquid
(such as the oils: ingredient ii)) with another immiscible liquid (such as water: ingredient iv) or an aqueous phase) preferably in the presence of an emulsifier (such as the surfactants, ingredient iii)), one of which is finely distributed in the other as droplets (see "Emulsions", Kirk-Othmer Encyclopedia of Chemical Technology, Edward Kostansek, published Online on 13/07/2012, DOI: 10.1002/0471238961 .051321 1206180902.a01.pub3).
The mean size of the droplets of the emulsion according to the invention is preferably between 10 nm and 100 μηη and preferably between 20 nm and 50 μηη. This is the mean diameter D(3.2), which may be measured especially using a laser particle sizer.
When the emulsion droplets size is less than or equal to 200 nm, these emulsions will be referred to as nanoemulsions or microemulsions, the first being thermodynamically unstable and the second being thermodynamically stable.
The emulsion may be direct, i.e. of oil-in-water (O/W) type, and the emulsion is then in the form of an aqueous continuous phase (or outer phase) in which is distributed a discontinuous fatty phase (or inner phase: oil + optionally solid fatty substances).
According to another preferred embodiment of the invention, the emulsion has a mean size of greater than 200 nm, and is an inverse emulsion, i.e. of water-in-oil (W/O) type, the emulsion then being in the form of a continuous fatty phase (or outer phase: oil + optionally solid fatty substances) in which is distributed a discontinuous aqueous phase (or inner phase).
The emulsion of the invention is prepared via standard processes for preparing emulsions or dispersions, which are well known to those skilled in the art (see, for example, 'Emulsions", Kirk-Othmer Encyclopedia of Chemical Technology, Edward Kostansek, published Online on 13/07/2012, DOI: 10.1002/0471238961.051321 1206180902.a01.pub3, point 3 "Preparation").
The microemulsions may be obtained by simple hot or cold mixing of the water, oils and surfactants, provided that the mixing lies within the correct zone of the phase diagrams.
The nanoemulsions are obtained via standard methods known to those skilled in the art
(see, for example, J. Phys.: Condens. Matter, "Nanoemulsions: formation, structure, and physical properties", T.G. Mason et al., 18, 635-666 (2006)).
The production of the nanoemulsions may take place by lying within adequate zones of the phase diagrams and using powerful stirring devices such as high-pressure homogenizers. It may also be performed via phase inversion techniques that are well known to those skilled in the art.
Preferably, the preemulsion according to the invention is a preemulsion of water or of aqueous phase in oil, i.e. of W/O type.
According to a particular embodiment, the predispersion of the invention is free of any surfactant. For the purposes of the present invention, the term "free of surfactants" means free of any non-polymeric compound with an HLB value of greater than or equal to 1 .
According to another advantageous embodiment of the invention, the predispersion comprises at least one surfactant, i.e. the ingredient iii) as defined previously. It is then referred to as a preemulsion as indicated above.
According to another variant, the predispersion comprises at least one stabilizing polymer compound, which is preferably silylated, such as those based on polydimethylsiloxane PDMS and/or on SMDI and polyalkylene glycol, especially polyethylene glycol and polypropylene glycol. This or these stabilizing polymer compound(s) may represent from 0.1 % to 20%, preferably from 0.5% to 15% by weight and better still from 1 % to 10% by weight, relative to the total weight of the said predispersion.
Preferably, the ready-to-use composition applied to the keratin fibres is not a compact solid.
//) the oil(s)
The composition of the invention, the final composition in the event of supplementary addition of water or the predispersion comprise one or more oils preferably of plant origin.
The term "o/7" means a "fatty substance" that is liquid at room temperature (25°C) and at atmospheric pressure (760 mmHg). The viscosity at 25°C is preferably less than 1200 cps and better still less than 500 cps (defined, for example, from the Newtonian plateau determined using an ARG2 rheometer from TA Instruments equipped with a spindle with cone-plate geometry 60 mm in diameter and with an angle of 2 degrees over a shear stress range of from 0.1 Pa to 100 Pa).
The term "fatty substance" means an organic compound that is insoluble in water at ordinary temperature (25°C) and at atmospheric pressure (760 mmHg) (solubility of less than 5%, preferably less than 1 % and even more preferentially less than 0.1 %). They have in their structure at least one hydrocarbon-based chain comprising at least 6 carbon atoms or a sequence of at least two siloxane groups. In addition, the fatty substances are generally soluble in organic solvents under the same temperature and pressure conditions, for instance chloroform, dichloromethane, carbon tetrachloride, ethanol, benzene, toluene, tetrahydrofuran (THF), liquid petroleum jelly or decamethylcyclopentasiloxane. More particularly, the oils are chosen from non-silicone oils and in particular C6-Ci6 hydrocarbons or hydrocarbons containing more than 16 carbon atoms and in particular alkanes; oils of animal origin; triglyceride oils of plant origin; essential oils; fluoro oils or glycerides of synthetic origin, fatty alcohols; fatty acid and/or fatty alcohol esters other than triglycerides, and silicone oils.
Preferably, the oils do not comprise any C2-C3 oxyalkylene units or any glycerolated units.
Preferably, the oils are not fatty acids which, in salified form, give water-soluble soaps. The oils that may be used as second ingredient ii) in the composition in accordance with the invention may be silicones.
The silicones may be volatile or non-volatile, cyclic, linear or branched silicones, which are unmodified or modified with organic groups, having a viscosity from 5x10"6 to 2.5 m2/s at
25°C, and preferably 1 *10"5 to 1 m2/s.

According to a particular embodiment of the invention, the composition comprises one or more butters, preferably of plant origin.
For the purposes of the present invention, the term "butter" (also known as a "pasty fatty substance") means a lipophilic fatty compound which undergoes a reversible solid/liquid change of state and which comprises, at a temperature of 25°C and at atmospheric pressure (760 mmHg), a liquid fraction and a solid fraction. In other words, the starting melting point of the pasty compound may be less than 25°C. The liquid fraction of the pasty compound, measured at 25°C, may represent 9% to 97% by weight of the compound. This liquid fraction at 25°C preferably represents between 15% and 85% and more preferably between 40% and 85% by weight.
Preferably, the butter(s) have an end melting point of less than 60°C.
Preferably, the butter(s) have a hardness of less than or equal to 6 MPa.
Preferably, the pasty fatty substances have, in the solid state, an anisotropic crystal organization, which is visible by X-ray observation.
For the purpose of the invention, the melting point corresponds to the temperature of the most endothermic peak observed on thermal analysis (DSC) as described in Standard
ISO 1 1357-3; 1999. The melting point of a pasty substance or of a wax may be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name DSC Q2000 by the company TA Instruments.
As regards the measurement of the melting point and the determination of the end melting point, the sample preparation and measurement protocols are as follows:
A sample of 5 mg of pasty fatty substance, preheated to 80°C and withdrawn with magnetic stirring using a spatula that is also heated, is placed in a hermetic aluminium capsule, or a crucible. Two tests are performed to ensure the reproducibility of the results.
The measurements are performed on the abovementioned calorimeter. The oven is flushed with nitrogen. Cooling is performed by an RCS 90 heat exchanger. The sample is then subjected to the following protocol: it is first placed at a temperature of 20°C, and then subjected to a first temperature rise passing from 20°C to 80°C, at a heating rate of 5°C/minute, then is cooled from 80°C to -80°C at a cooling rate of 5°C/minute and finally subjected to a second temperature rise passing from -80°C to 80°C at a heating rate of 5°C/minute. During the second temperature increase, the variation of the difference in power absorbed by the empty crucible and by the crucible containing the sample of butter is measured as a function of the temperature. The melting point of the compound is the temperature value corresponding to the top of the peak of the curve representing the variation in the difference in power absorbed as a function of the temperature. The end melting point corresponds to the temperature at which 95% of the sample has melted.
The liquid fraction by weight of the butter at 25°C is equal to the ratio of the heat of fusion consumed at 25°C to the enthalpy of fusion of the butter.
The heat of fusion of the pasty compound is the heat consumed by the compound in order to pass from the solid state to the liquid state. The butter is said to be in the solid state when all of its mass is in crystalline solid form. The butter is said to be in the liquid state when all of its mass is in liquid form.
The heat of fusion of the butter is equal to the integral of the entire melting curve obtained using the abovementioned colorimeter, with a temperature rise of 5 or 10°C/minute, according to Standard ISO 1 1357-3:1999. The heat of fusion of the butter is the amount of energy required to make the compound change from the solid state to the liquid state. It is expressed in J/g.
The heat of fusion consumed at 25°C is the amount of energy absorbed by the sample to change from the solid state to the state that it has at 25°C, constituted of a liquid fraction and a solid fraction.
The liquid fraction of the butter measured at 32°C preferably represents from 30% to 100% by weight of the compound, preferably from 50% to 100%, more preferably from 60% to 100% by weight of the compound. When the liquid fraction of the butter measured at 32°C is equal to 100%, the temperature of the end of the melting range of the pasty compound is less than or equal to 32°C.
The liquid fraction of the butter measured at 32°C is equal to the ratio of the heat of fusion consumed at 32°C to the heat of fusion of the pasty compound. The heat of fusion consumed at 32°C is calculated in the same way as the heat of fusion consumed at 23°C.
As regards the measurement of the hardness, the sample preparation and measurement protocols are as follows:
The composition according to the invention or the butter is placed in a mould 75 mm in diameter, which is filled to about 75% of its height. In order to overcome the thermal history and to control the crystallization, the mould is placed in a Votsch VC0018 programmable oven, where it is first placed at a temperature of 80°C for 60 minutes, then cooled from 80°C to 0°C at a cooling rate of 5°C/minute, and then left at the stabilized temperature of 0°C for 60 minutes, and then subjected to a temperature rise ranging from 0°C to 20°C, at a heating rate of 5°C/minute, and then left at the stabilized temperature of 20°C for 180 minutes.
The compression force measurement is taken using a TA TX2i texturometer from Swantech. The spindle used is chosen according to the texture:
- cylindrical steel spindle 2 mm in diameter for very rigid starting materials;
- cylindrical steel spindle 12 mm in diameter for sparingly rigid starting materials. The measurement comprises three steps:
- a first step after automatic detection of the surface of the sample, where the spindle moves at a measuring speed of 0.1 mm/second, and penetrates into the composition according to the invention or the butter to a penetration depth of 0.3 mm, and the software notes the maximum force value reached;
- a second step, known as relaxation, where the spindle remains in this position for one second and the force is noted after 1 second of relaxation; and finally
- a third step, known as withdrawal, where the spindle returns to its original position at a speed of 1 mm/second, and the withdrawal energy of the spindle (negative force) is noted.
The hardness value measured during the first step corresponds to the maximum compression force measured in newtons divided by the area of the texturometer cylinder expressed in mm2 in contact with the butter or the composition according to the invention. The hardness value obtained is expressed in megapascals or MPa.

Dveinp process using the composition of the invention
According to a particular embodiment P1 of the invention, the dyeing process is performed in several steps:
- the first step consists in preparing composition (la) of the invention, i.e. the composition obtained by mixing at the time of use the ingredient i) as defined previously with the predispersion as defined previously optionally with supplementary addition of water to give the final composition (lla);
- in the second step, composition (la) or (lla) is applied to the keratin fibres and is left on the said fibres preferably for a minimum time of 30 minutes, preferentially a time ranging from 30 minutes to 24 hours and better still ranging from 1 hour to 12 hours;
- in the third step, the keratin fibres are rinsed with water until the poultice has disappeared, preferably without shampooing;
- the keratin fibres may then be dried or left to dry naturally, without a hairdryer.
According to another particular embodiment P2 of the invention, the dyeing process is performed in several steps:
- the first step consists in preparing composition (la) or (lla) of the invention as described previously;
- in the second step, composition (la) or (lla) is left to stand for several hours, preferably 24 hours, and is then applied preferably in the form of a poultice and left on the said fibres preferably for a minimum time of 30 minutes (preferably ranging from 30 minutes to 24 hours and better still from 1 hour to 12 hours);
- in the third step, the keratin fibres are rinsed with water until composition (la) or (lla) has disappeared, preferably without shampooing;
- the keratin fibres may then be dried or left to dry naturally, without a hairdryer.
According to a particularly advantageous process, after the third step of P1 or P2, the keratin fibres are:
a) either mechanically wiped with a towel or absorbent paper,
b) or dried by heat with a heat source (confection, convention or radiation) by passing over, for example, a stream of a warm gas such as air necessary to evaporate off the solvent(s); heat sources that may be mentioned include a hairdryer, hairdrying hoods, a hair-straightening iron, an infrared ray dispenser and other standard heating appliances.
Irrespective of the application method, the application temperature for composition (la) or (lla) ranges from room temperature (15 to 25°C) to 80°C and more particularly from 15 to 45°C. Thus, after application of the ready-to-use composition according to the invention, the head of hair may advantageously be subjected to a heat treatment by heating to a temperature ranging from 30 to 60°C. In practice, this operation may be performed using a styling hood, a hairdryer, an infrared ray dispenser or other standard heating appliances.
Use may be made, both as means for heating and straightening the hair, of a heating iron at a temperature ranging from 60 to 220°C and preferably from 120 to 200°C.
A specific form of the invention relates to a dyeing process which is performed at room temperature (25° C).
Irrespective of the dyeing process, in particular of P1 and P2 as defined previously, if ingredient i) used is henna powder, each of these processes may be followed by another dyeing process P1 or P2 comprising as ingredient i) indigo; and vice versa, i.e. irrespective of the dyeing process P1 or P2 as defined previously, if ingredient i) used is indigo, each of these processes may be followed by another dyeing process P1 or P2 comprising as ingredient i) henna powder.
More specifically, the dyeing process may take place, for example, in three different ways.
Process 1 :
Henna and/or indigo powder (1 part) is mixed with the predispersion (0.5 part) and with water at a temperature of between 40 and 98°C (2.5 parts) in a bowl, and the whole is then mixed for the time required to obtain a creamy poultice. The poultice is then applied to the head for a minimum time of 30 minutes (preferably between 30 minutes and 24 hours and better still between 1 hour and 12 hours) before rinsing without shampooing, and the hair is then dried. Process 2:
Henna and/or indigo powder (1 part) is mixed with the predispersion (0.5 part) and with water at a temperature of between 10 and 40°C (2.5 parts) in a bowl, and the whole is then mixed for the time required to obtain a creamy poultice. The poultice is then applied to the head for a minimum time of 30 minutes (preferably between 30 minutes and 24 hours and better still between 1 hour and 12 hours) before rinsing without shampooing, and the hair is then dried. Process 3:
The cream (cationic preemulsion as a nanoemulsion or microemulsion or emulsion, i.e. comprising at least one cationic surfactant as defined previously) mixed with henna and/or indigo powder is applied to the head for a minimum time of 30 minutes (preferably between 30 minutes and 24 hours and better still between 1 hour and 12 hours) before rinsing without shampooing, and the hair is then dried.
Irrespective of the application method, the application temperature of the composition comprising i) to iv) to the keratin fibres ranges from room temperature (15 to 25°C) to 80°C and more particularly from 15 to 45°C. Thus, after application of the poultice according to the invention, the head of hair may advantageously be subjected to a heat treatment by heating to a temperature ranging from 30 to 60°C. In practice, this operation may be performed using a styling hood, a hairdryer, an infrared ray dispenser or other standard heating appliances.
More particularly, the process of the invention is performed according to the following two processes:
- Process 4:
A composition preferably in the form of a poultice containing henna and/or indigo- producing plant(s) in an amount of 1 part by weight and water at a temperature inclusively between 40 and 98°C for an amount of 2-3 parts by weight i) is applied to the head for a minimum time of 30 minutes, preferably between 30 minutes and 24 hours and better still between 1 hour and 12 hours, followed by ii) rinsing preferably without shampooing, and then iii) the hair is dried; next, iv) a heating iron at a temperature inclusively between 100 and 230°C and preferably between 130 and 180°C is used along the length of the head of hair;
- Process 5:
A composition preferably in the form of a poultice containing henna and/or indigo- producing plant(s) in an amount of 1 part by weight and water at a temperature inclusively between 10 and 40°C for an amount of 2-3 parts by weight i) is applied to the head for a minimum time of 30 minutes, preferably between 30 minutes and 24 hours and better still between 1 hour and 12 hours, followed by ii) rinsing preferably without shampooing, and then iii) the hair is dried; next, iv) a heating iron at a temperature between 100 and 230°C and preferably between 130 and 180°C is used along the length of the head of hair.
A specific form of the invention relates to a dyeing process which is performed at room temperature (25° C).
According to a particularly advantageous embodiment of the invention, all the ingredients used in the process are of natural origin, and preferably of plant origin.
The evaluation of the coloration can be done visually or read on a spectrocolorimeter (such as Minolta CM3600d, illuminant D65, angle 10°, SCI values) for the L*, a*, b* colorimetric measurements. In this L*, a*, b* system, L* represents the intensity of the color, a* indicates the green/red color axis and b* indicates the blue/yellow color axis. The lower the value of L, the darker or more intense the color. The higher the value of a*, the redder the shade; the higher the value of b*, the yellower the shade. The variation in coloring between the colored locks of natural white hair (NW) which is untreated (control) and after treatment or coloration are defined by ΔΕ*, corresponding to the colour uptake on keratin fibers, according to the following equation:
ΔΕ* = -(L*— Lo *)2 +(a*— ao * f + (b* - b0 *)2
In this equation, L*, a* and b* represent the values measured after dyeing the natural hair comprising 90% of white hairs and L0 *, a0 * and b0 * represent the values measured for the untreated natural hair comprising 90% of white hairs.
The greater the value of ΔΕ, the greater the difference in color between the control locks and the dyed locks and the greater colour uptake is.
On the other hand for evaluating the selectivity of the color between the root and tip of the keratin fiber, measurement can be done on permed or sensibilised white hair (PW) and natural white hair, wherein the variation in coloring between the colored locks PW and the colored natural white hair are defined by ΔΕ*, corresponding to the selectivity of the colour, is calculated according to the following equation:
ΔΕ* = -(L*— Lo *)2 +(a*— ao * f + (b* - b0 *)2
In this equation, L*, a* and b* represent the values measured after dyeing the natural hair comprising 90% of white hairs and L0 *, a0 * and b0 * represent the values measured after dyeing the permed or sensibilised hair. The lowest ΔΕ*, the best homogeneity of the hair color.
If the light fastness is investigated, ΔΕ* is also calculated for the L0 *, a0 *, b0 * and L*, a*, b* measured of the locks before and after exposure to the light, respectively.
Chromaticity in the CIE L*, a*, b* colorimetric system is calculated according to the following equation :
Figure imgf000043_0001
The greater the value of C*, the greater the chromaticity is.
The examples that follow serve to illustrate the invention without, however, being limiting in nature. DYEING EXAMPLES

• process P1 consists in:
- in the first step, preparing the composition according to any one of the preceding claims; - in the second step, the said composition is: a) either immediately applied to the keratin fibres, and left on the fibres for a minimum time of 30 minutes, preferentially ranging from 30 minutes to 24 hours and particularly from 1 hour to 12 hours,
b) or left to stand for several hours, preferably 24 hours, and then applied and left on the fibres for a minimum time of 30 minutes, preferably ranging from 30 minutes to 24 hours and particularly from 1 hour to 12 hours;
- in the third step, the keratin fibres are rinsed with water until the composition has disappeared, preferably without shampooing;
- the keratin fibres may then be dried with a source of heat or left to dry naturally at room temperature;
• and process P2 consists in:
- in the first step, preparing the composition as described previously;
- in the second step, the said composition is left to stand for several hours, preferably 24 hours, and the said composition is then applied and left on the said fibres preferably for a minimum time of 30 minutes, preferably ranging from 30 minutes to 24 hours and particularly from 1 hour to 12 hours;
- in the third step, the keratin fibres are rinsed with water until the composition has disappeared, preferably without shampooing;
- the keratin fibres may then be dried with a source of heat or left to dry naturally at room temperature;
preferably, after the third step of P1 or P2, the keratin fibres are:
a) either mechanically wiped with a towel or absorbent paper,
b) or dried by heat with a heat source by passing over, for example, a stream of a warm gas such as air necessary to evaporate off the solvent(s); heat sources that may be mentioned include a hairdryer, hairdrying hoods, a hair-straightening iron, an infrared ray dispenser and other standard heating appliances;
it being understood that irrespective of the dyeing process P1 or P2 as defined previously, if ingredient i) used is henna powder, each of these processes may be followed by another dyeing process P1 or P2 comprising as ingredient i) indigo; and vice versa, i.e. irrespective of the dyeing process P1 or P2 as defined previously, if ingredient i) used is indigo, each of these processes may be followed by another dyeing process P1 or P2 comprising as ingredient i) henna powder.
25. Use of the composition according to any one of Claims 1 to 23, for dyeing keratin fibres such as the hair.
