Definitions

  • the present invention relates to a dye composition in foam form.
  • oxidation dyeing or permanent dyeing. More particularly, this form of dyeing uses one or more oxidation dyes, usually one or more oxidation bases optionally combined with one or more couplers.
  • oxidation bases are chosen 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 access to coloured entities.

  • Permanent dyeing processes thus consist in using, with the dye composition, 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 aqueous ammonia or other alkaline agents, such as alkanolamines.
  • Dye compositions may take various forms such as lotions, gels, emulsions, creams or foams.

Description

FOAM DYE COMPOSITION COMPRISING AT LEAST TWO DIOL COMPOUNDS EACH COMPRISING AT LEAST 4 CARBON ATOMS
The present invention relates to a dye composition in foam form.
Among the methods for dyeing human keratin fibres, such as the hair, mention may be made of oxidation dyeing or permanent dyeing. More particularly, this form of dyeing uses one or more oxidation dyes, usually one or more oxidation bases optionally combined with one or more couplers.
In general, oxidation bases are chosen 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 access to coloured entities.
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 colors to be obtained.
Permanent dyeing processes thus consist in using, with the dye composition, 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 aqueous ammonia or other alkaline agents, such as alkanolamines.
Dye compositions may take various forms such as lotions, gels, emulsions, creams or foams. Dyeing foams are pleasant to use, however they often exhibit a poor staying power over time. For example, it is possible to observe a rapid disappearance of the foam after application or a non-uniform application along the fibres.
There is a real, constant need to develop oxidation dye compositions in foam form that are easy to prepare and to apply, and which remain sufficiently stable over time while retaining efficient dyeing properties.
This aim and others are achieved by the present invention, one subject of which is thus a composition for dyeing keratin fibres such as the hair, in foam form, comprising at least one alkaline agent, at least one oxidizing agent, at least one oxidation dye precursor and at least two diol compounds comprising at least 4 carbon atoms selected from dipropylene glycol, diethylene glycol and hexylene glycol.
The invention also relates to a process for dyeing human keratin fibres using this composition.
A subject of the invention is similarly a multi-compartment device comprising, in a first compartment, a first composition containing at least one oxidation dye precursor, at least one alkaline agent and at least two diol compounds comprising at least 4 carbon atoms selected from dipropylene glycol, diethylene glycol and hexylene glycol ; in a second compartment, a second composition containing one or more oxidizing agents, one of the two compartments being equipped with a component for delivering the composition of the invention in foam form after mixing with the other composition, or the component for delivering the composition in foam form is included in a third compartment.
A subject of the invention is also a device for dyeing keratin fibres, comprising the composition of the invention in liquid form and a foam dispenser for delivering the composition in the form of a foam.
The composition of the invention is in the form of a foam that is particularly pleasant to apply. It has a light, airy texture, which makes it particularly pleasant to use. The qualities of the foam are sufficiently long-lasting to enable uniform application of the dye product, without running. The composition of the invention makes it possible to obtain improved dyeing properties, such as strength of the colour, resistance to external agents (shampooing, perspiration, light) and selectivity, which are particularly efficient.
Other features and advantages of the invention will become more clearly apparent on reading the description and the examples that follow.

Among the monoglycerolated or polyglycerolated alcohols, it is more particularly preferred to use the C8/Ci0 alcohol containing 1 mol of glycerol, the C10/C12 alcohol containing 1 mol of glycerol and the C12 alcohol containing 1.5 mol of glycerol. Nonionic surfactants that may also be mentioned include non-oxyethylenated fatty acid esters of sorbitan, fatty acid esters of sucrose, optionally oxyalkylenated alkylpolyglycosides, alkylglucoside esters, derivatives of N-alkylglucamine and of N- acylmethylglucamine, aldobionamides and amine oxides.
According to one embodiment of the invention, the composition comprises one or more nonionic or anionic surfactants. Preferentially, the composition of the invention comprises one or more nonionic surfactants.
The total content of surfactants in the composition of the invention is in general from 0.1 % to 30% by weight, preferably from 1 % to 20% by weight and better still from 2% to 10% by weight, relative to the weight of the composition.
The composition may also contain various adjuvants conventionally used in compositions for dyeing or lightening the hair, such as anionic polymers, cationic polymers, and nonionic polymers, or mixtures thereof; antioxidants; penetrants; sequestrants; fragrances; dispersants; film-forming agents; ceramides; preserving agents; opacifiers.
The above adjuvants are generally present in an amount for each of them of between 0.01 % and 20% by weight relative to the weight of the composition.
Preferentially, the composition according to the invention comprises one or more cationic polymers.
The composition according to the invention may comprise water and/or one or more organic solvents other than the diols of the invention.
Examples of organic solvents that may be mentioned include monoalcohols, such as ethanol or isopropanol; aromatic alcohols such as benzyl alcohol or phenylethyl alcohol; polyols other than the diols of the invention, such as glycerol or propylene glycol; polyol ethers, for instance ethylene glycol monomethyl, monoethyl or monobutyl ether, propylene glycol ethers, for instance propylene glycol monomethyl ether; and also diethylene glycol alkyl ethers, especially Ci-C4 alkyl ethers, for instance diethylene glycol monoethyl ether or monobutyl ether, alone or as a mixture.
The organic solvents other than the diols of the invention, when they are present, generally represent between 1 % and 40% by weight relative to the total weight of the dye composition, and preferably between 5% and 30% by weight relative to the total weight of the dye composition.
The composition is preferably aqueous. In this case, it preferably comprises from 30% to 95% by weight of water, better still from 40% to 90% by weight of water and even better still from 50% to 85% by weight of water relative to the total weight of the composition. The pH of the composition according to the invention, if it is aqueous, is generally between 3 and 12, preferably between 5 and 1 1 and preferentially between 7 and 1 1 , limits inclusive.
It may be adjusted to the desired value by means of acidifying or basifying agents usually used in the dyeing of keratin fibres, and in particular the aforementioned alkaline agents of the invention.
The composition, before dispersing in the form of a foam, may result from the mixing of two or more than two compositions.
The composition according to the invention is, on application to the keratin fibres, in the form of a foam.
The composition in foam form according to the invention is formed from a mixture of air or an inert gas with the composition described previously.
According to one particularly preferred embodiment, the composition according to the invention is in the form of a temporary foam produced just before use.
The composition may be packaged in a foam dispenser. They may either be products known as "aerosols" dispensed from a pressurized container with the aid of a propellent gas and thus forming a foam at the moment they are dispensed, or compositions dispensed from a container using a mechanical pump connected to a dispensing head, the passage of the composition into the dispensing head converting it into a foam at the latest at the outlet orifice of such a head.
The propellant gas that may be used may be chosen from carbon dioxide, nitrogen, nitrogen oxide, dimethyl ether, volatile hydrocarbons such as butane, isobutane, propane and pentane, and mixtures thereof.
According to another embodiment, the composition may be in a foam dispenser of "pump-action bottle" type. These dispensers comprise a dispensing head for delivering the composition, a pump and a dip tube for transferring the composition from the container into the head in order to deliver the product. The foam is formed by forcing the composition to pass through a material comprising a porous substance such as a sintered material, a filtering grid made of plastic or of metal, or similar structures.
Such dispensers are well known to those skilled in the art and are described in patents: U.S. Pat No. 3 709 437 (Wright), U.S. Pat. No. 3 937 364 (Wright), U.S. Pat No. 4 022 351 (Wright), U.S. Pat No. 4 147 306 (Bennett), U.S. Pat No. 4 184 615 (Wright), U.S. Pat No. 4 598 862 (Rice), U.S. Pat No. 4 615 467 (Grogan et al.), and U.S. Pat No. 5 364 031 (Tamiguchi et al.). In practice, for this variant, the oxidizing agent(s) are packaged in a first container equipped with a closure, and the oxidation dye precursor(s) are packaged in a second container, different from the first, and also closed by a closing member. The closing member may be a pump-dispensing mechanism. The composition according to the invention is then formed by mixing, before use, a composition with the oxidizing agent(s) and a composition with the oxidation dye precursor(s). To this end, to limit the number of containers provided, one from among the first and second container defines an internal volume that is sufficient to receive therein all of the two compositions. The mixture of the compositions may be homogenized by closing this container and by shaking the container. The closure of the container is advantageously carried out directly with the dispensing head. This dispensing head comprises a mechanical pump held in a ring intended for mounting by snap-fitting or screwing onto the neck of the container containing the mixture. The pump comprises a pump body connected to a dip tube to enable the whole of the mixture to be dispensed. The pump also comprises a push button for activation of the pump body, such that, on each activation, a dose of composition is sucked inside the dip tube and ejected in foam form out of the dispensing orifice of the head.
The containers are preferentially made of a thermoplastic material, and obtained via extrusion blow-moulding or injection blow-moulding processes. In particular, the container for conditioning the composition with the oxidation dye precursor(s) may be (to be reported in other projects) made of a material comprising a non-zero proportion of EVOH. The pump is, for example, the standard "F2 - L9" model offered by the company Rexam.
According to this preferred embodiment, one subject of the invention is a non-aerosol device comprising the composition of the invention in liquid form.
The dyeing process according to the invention consists in applying the composition according to the invention to wet or dry keratin fibres over a time sufficient to develop the desired coloration. According to the invention, the composition applied to the keratin fibres is in foam form. The dyeing process is generally performed at room temperature (between 15 and 25°C) and up to temperatures that may be as high as 60°C to 80°C.
After a leave-on time of from one minute to one hour and preferably from 5 minutes to 30 minutes, the human keratin fibres are rinsed with water, and optionally washed with a shampoo and then rinsed with water.
The examples that follow serve to illustrate the invention without, however, being limiting in nature. EXAMPLES

The mixture is introduced in an amount of 65 g (26 g of composition A + 39 g of composition B) into a pump bottle (Rexam L9 equipped with a dip tube). The device produces a sufficiently compact foam on pumping. This foam is applied to natural or permanent-waved grey hair containing 90% white hairs, without disintegrating immediately on application.
The comfort on application is very good. After a leave-in time of 30 minutes, the locks are rinsed, washed with a standard shampoo, rinsed again and then dried, to give a dark chestnut-brown coloration. This coloration is strong and sparingly selective.
