Description

,.r SOLID COMPOSITIONS
FIELD OF THE INVENTION
The present invention relates to a solid composition, particularly for coloring and/or bleaching hair.

BACKGROUND OF THE INVENTION
It is known already systems for custom coloration of keratinous fibers, particularly mammal hair such as human hair. See for example I'CI' patent application W02012/127429 from COLORIGI IT LTD, published on 2711` September 2012. W020121127429 discloses particularly methods, systems; tablet formulations, a dispensing device configured for dispensing tablet formulations, an optical reader for obtaining optical information from keratinous fibers, a device and a method for predicting the treatment operation of keratinous fibers and for selecting a suitable composition for treating keratinous fibers according to the prediction, and systems for custom treatment of keratinous fibers which utilize any of the tablet formulations, dispensing device, optical reader and predicting device and method, either alone or in combination.
There is a need for providing solid compositions =--. e.g. tablet formulations exhibiting a superior performance and being particularly suitable for use with the methods, systems, and devices as those disclosed in W02012/127429.
SUMMARY OF THE INVENTION
The present invention relates to a solid composition as described hereinafter, particularly for use with the methods, systems, and devices as those disclosed in W02012/127429.
The present invention also relates to head-on compositions thereof, method for preparing thereof, kits thereof, packaging thereof:

DETAILED DESCRIPTION OF THE INVENTION
The inventors have surprisingly found that the use of the systems and devices, as well as the methods disclosed for example in PCT patent application W02012/127429, which is incorporated herewith in its entirety, can be improved further by designing and using specific solid compositions and kits thereof, and particularly by carefully selecting the types and proportions of components to be incorporated into these compositions and kits thereof Specifically, it has been found that the treatment of the keratinous fibers was improved by selecting specific types of dyes to be incorporated into the composition;
and/or by selecting specific chelants, radical scavengers, solvents, oxidizing agents, thickeners and/or a rheology modifiers, carbonate ion sources, conditioning agents, surfactants, alkalizing agents, pH
modifiers and/or buffering agents, and/or binder.

Solid compositions By "solid composition", it is meant the composition to be stored. T his composition is not suitable for use as such for treating keratinous fibers. In contrast, it is not meant the final composition, i.e.
the ready-to-use composition to be made shortly before applying in on-head and/or treating the keratinous fibers.
The present invention also relates to a composition in a solid form. The composition may be in the form of a (solid) tablet, alternatively in a (solid) pulverulent form, alternatively in the form of a (solid) foam.
The solid composition may be uncoated or coated. When coated, the composition may be partially coated, or integrally coated.
Whenever proportions, ranges and concentrations are expressed "by weight of the total composition", it is meant by weight of the total composition i.e. by weight of the total solid composition, without coating and before dilution/dissolution/disintegration into a medium and/or mixing with another composition. Whenever proportions, ranges and concentrations are expressed "by weight of the total on-head composition", it is meant by weight of the total final (ready-to-use) composition, after dilution/dissolution/disintegration into a medium and/or mixing with another composition and being ready for being applied onto keratinous fibers.
The solid composition is substantially free of water. By "substantially free", it is meant that the composition comprises less than about 5%, alternatively less than about 4%, alternatively less than about 3%, alternatively less than about 2%, alternatively less than about 1% water by weight of the total composition, or alternatively is free of water.

Disintegration rate and other properties The solid composition is fast-disintegrating, and has a Disintegration rate of less than about 5 minutes, alternatively less than about 3min, alternatively less than about 2min, alternatively less than about /aria, alternatively less than about 30 seconds, alternatively less than about 15sec, alternatively less than about Ssec, alternatively less than about 3sec,. The Disintegration rate. may be measured using conventional methods. It has been surprisingly found that providing composition with such disintegration profile allows obtaining an improved bleaching and/or dyeing performance. Indeed, time management is key when wanting to bleach and/Or color hair.
A composition having such Disintegration profile can be obtained by using chemical and/or physical means. Further preferred properties can be found in W02012/127429, particularly the disclosure from page 109, line 28 to page 113, line 12, which is incorporated herewith by reference.

Superdisintegrant agents As per chemical means, the composition may comprise a component suitable for obtaining a Disintegration rate as defined hereinbefore. The composition may comprise a superdisintegrant component. By "superdisintegrant component", it is meant a component having a water absorption ratio of at least about 0.5, alternatively from about 0.5 to about 2, alternatively from about 0.5 to about 1.5, alternatively from about 0.6 to about 0.9. The water absorption ratio is defined as the change in weight following wetting of the tablet divided by the weight of the dry tablet.
The superdisintegrant component may be substantially water-insoluble. By "water-insoluble", it is meant that the superdisintegrant component has a solubility of less than about l.Ograrn.s, alternatively less than about 3g, alternatively less than about 0.3g, alternatively less than about 0.1g per kg of water (at 25 C, pH 7). The superdisintegrant component may be selected from the group consisting of polymeric superdisintegrant components, non-polymeric superdisintegrant components, or mixtures thereof, alternatively from the group consisting of crosslinked polymers; alternatively from the group consisting of crosslinked celluloses, crosslinked polyvinylpyrolidone, crosslinked starch, crosslinked alginic acid, crosslinked poly(meth)acrylic acid, polysaccharides, and mixtures thereof, alternatively from the group consisting of crosslinked celluloses, crosslinked polyvinylpyrroli done, crosslinked starch, and mixtures thereof, alternatively from the group consisting of crosslinked carboxyrnethyl cellulose, crosslinked polyvinylpyrrolidone, sodium starch glycolate, and mixtures thereof. Commercially available superdisintegrant components may be found for example under the brands Ac-Di-Sol , Polyplasdon.e and Primo;ei .
The solid composition may comprise a total amount of superdisintegrant components of less than about 10%, alternatively from about 0.5 to about 10%, alternatively less than about 5%, alternatively from about 0.5% to about 5%, alternatively less than about 3%, alternatively from about 0,5% to about 3%, by weight of the total composition.
Disintegration auxiliary component The solid composition may also comprise a disintegration auxiliary component, alternatively a water-soluble disintegration auxiliary component, By "disintegration auxiliary component", it is meant any component that would contribute to the Disintegration profile of the present composition, particularly by exhibiting a low compressibility and cohesiveness enhancing tablet porosity and thus facilitating tablet disintegration via capillary action and/or by exhibiting an intrinsic disintegrating property. This includes a spray-dried or agglomerated water-soluble agent, a binder with an intrinsic disintegrating property, an exothermic agent, a non-swellable agent., it gas-releasing agent, an enzymatic system.

Solvents, humectants In addition to water (if present - even though the solid composition is preferably substantially free of water), the composition according to the present invention may further comprise an additional solvent, The additional solvent may be selected from at.. least one organic solvent to dissolve the compounds that would not typically be sufficiently soluble in water.
Suitable organic solvents include, but are not limited to: Cl to C4 lower alkanols (such as ethanol, propanol, isopropanol); aromatic alcohols (such as benzyl alcohol and phenoxyethanol);
polyols and polyol ethers (such as carbitols, 2-butoxyetbanol, propylene glycol, propylene glycol monotnethyl ether, diethylene glycol monoethyl ether, monotnethyl ether, hexylene glycol, glycerol, ethoxy glycol, butoxydiglycol, ethoxydiglycerol, dipropyleneglocol, polygylcerol);

isopropanol, glycerol, 1.2-propylene glycol, hexylene glycol, ethoxy diglycol, and mixtures thereof.
The solid composition may comprise a total amount of additional solvents of no more than about 30% by weight of the total composition. Typically, when present, the on-head composition comprises a total amount of organic solvents ranging from about 1% to about 30%, by weight of the total on-head composition.

Hinders and/or fillers The composition according to the present invention may further comprise a binder and/or a filler.
The solid composition may comprise a total amount of binders and/or fillers ranging from about 50%, alternatively from about 60%, alternatively from about 70%, alternatively from about 80%, by weight of the total composition.
Suitable binders and/or fillers include, but arc not limited to: proteins;

Ionic strength The on-head composition of the present invention may further have an ionic strength as defined herein of less than about 1.35mole/kg, alternatively from about 0.10 to about 0.75 mole/kg, alternatively from about 0.20 to about 0.60 mole/kg. Whilst not being bound by theory, it is believed that the ionic strength value may also affect the resultant viscosity and root adhesion properties of the composition. The ionic strength can be affected by salt resources such as the dyes, sodium sulphate, ammonium carbonate anti-oxidants and chelants such as EDDS. The dye tends to have the greatest effect on the ionic strength and thus the amounts added in order to provide any particular shade need to be considered in terms of ionic strength as well as dye outcome in order to prevent viscosity and root adhesion problems.
The ionic strength of the composition is a function of the concentration of all ions present in that solution and is determined according to the formula:
T rc nji j z2 where mi = molality of ion i (M - mot-/Kg H20), zi = charge number of that ion, and the sum is taken over all ions in the solution. For example, for a 1: 1 electrolyte such as sodium chloride, the ionic strength is equal to the concentration, but for MgSO4 the ionic strength is four times higher.
Generally multivalent ions contribute strongly to the ionic strength.
For example the ionic strength of a mixed 0.050 M Na2SO4 and 0.020 M NaCI
solution is: I
1/2 ((2 x (+1)2 x 0.050) (+1)2 x 0.020 + (---))2 x 0.050 + (-1)` x 0.020) =
0.17 M.

Method of Use/Kits It is understood that the examples of methods of use and embodiments described herein are for illustrative purposes only and that various modifications or changes in light thereof will be suggested to one skilled in the art without departing from the scope of the present invention.
5 Retail oxidative hair dye compositions are usually sold in kits comprising, in individually packaged components such as separate containers, a dye component (also called "dye cream" for emulsions or "dye liquid" for solutions) comprising the oxidative dye precursors and alkalizing agent which is typically ammonia in a suitable carrier and; a oxidizing component (also called "hydrogen peroxide cream" for emulsions or "hydrogen peroxide liquid" for solutions) 10 comprising the oxidizing agent (usually hydrogen peroxide). The consumer mixes the dye component and oxidizing component together immediately before use and applies it onto the hair. Similarly, retail bleaching compositions are also usually sold as a kit comprising two or three individually packaged components typically in two or three separate containers. The first component comprises the ammonium ion source (e.g. ammonia), the second component 15 comprises the oxidizing agent and the third (optional), component comprises a second oxidizing agent. The bleaching compositions are obtained by mixing the above-mentioned compositions immediately before use. As an alternative to the retail oxidative hair dye compositions usually sold, the products may be provided to the consumer as solid compositions, as described hereinbefore. The products may also be provided in a liquid/cream form to the consumer (for 20 example by adding to the solid composition(s) a medium, particularly an aqueous medium or water), for the consumer to mix these compositions to obtain an on-head composition, ready for application onto hair.
For, the professional hair salon market, the hair dye component and the oxidizing component and/or bleaching compositions are typically supplied independently, like in the present case in 25 the form of solid composition(s), to allow the professional to select a preferred combination.
After working the combined mixture for a few minutes (to insure uniform application to all of the hair), the oxidative dye composition is allowed to remain on the hair for an amount sufficient for the dyeing to take place (usually from about 2 to about 60 minutes, typically about 30 to about 45 minutes). The consumer or salon professional then rinses the hair thoroughly with water acid/'or 30 shampoo and allows it to dry. It will be observed that the hair has changed from its original colour to the desired colour.

Suitable kits comprising the solid composition according to the present invention can be found in W02012/127429, particularly the disclosure from page 122, line 13 to page 126, line 25, which is incorporated herewith by reference.
In both retail and professional applications, an optional conditioning agent can also be provided.
In this embodiment, all three compositions can be mixed immediately before use and applied together, or the conditioning agent can be applied (after an optional rinse step), as a post-treatment immediately after the oxidative dye composition or bleaching composition resulting from the mixture of the other containers.
The kits may also comprise as optional components a pre-treatment composition and/or a colour refresher composition Such colour refresher compositions comprise at least one pre-formed dye and may be applied to the hair immediately after the oxidative colour Le, from about I minute after oxidative hair dye or bleach application to about 60 days after the application. These colour refresher composition can be used to increase the initial colour obtained and or boost the colour during the wash and style cycle until the next oxidative colouring or bleaching event.
Viscosity According to the present invention, the dye composition and the oxidizing composition may be, independently from one another, prepared - from a solid corriposition(s) as so called thin liquids or thicker type creams. Typically, thin type liquids have a viscosity of less than about 1000cPs. Thick type creams typically have a viscosity of from about I000cPs.
Upon mixing the dye and oxidizing compositions, the resultant hair coloring and nor bleaching on-head composition preferably have a viscosity of from about 1000 to about 60000cPs, alternatively from about 2000 to about 30000 cPs, alternatively from about 3000 to about 25000 cPs. Viscosity is measured using Brookfield viscometers with cone and platy attachment. For viscosities in the range of about 0 to about 12000 ePs, the Brookfield DV-11 viscometer with S42 plate is used. 2rii1 sample of the composition is equilibrated at 26.7 C
for three minutes before the readings are taken at 1 rpm. For viscosities in the range of about 12,000 to about 60,000 cPs, the Brookfield DV-1 viscometer with S52 plate is used. 0,5rnl sample of the composition is equilibrated for 1 minute at 26.7 C before the readings are taken at 1 rpm.
Method of manufacture of the solid composition The solid compositions according to the present invention may be prepared in a tablet form by compression technique. Conventional compression techniques could be used such as those that can be found in W02012/127429, particularly the diisclosure from page 113, Sine 13 to page 118, line 14, which is incorporated herewith by reference.

Methods of manufacture The kits described hereinabove are well-known in the art and the compositions in each container can be manufactured utilizing any one of the standard approaches, these include a) `Oil-ins-water' process, b) `Phase Inversion' process and c) `One-pot' process. Such compositions may be prepared from solid composition(s) according to the present invention. For example, when using "oil-ins-water" process, surfactants of the present invention are added to approximately 50% of total water amount of the composition at about 40 C, homogenized for 15 to 30 min, then cooled to room temperature thus forming gel network thickener premix; this premix is then mixed cold with remaining amounts of water, other optional components and/or oxidizing agent, thus forming the first and second component parts of the above described bleaching or colouring kit, Packaging and dispensing devices The present invention may be provided in a variety of packaging devices and/or dispensing devices. These dispensing devices can come in the form of separate devices which may he used independently or in combination with one another. Typically, the hair colouring or bleaching compositions are contained within separate single or multi compartment containers so that the compositions can be stored separately from one another before use. The compositions are then mixed together by a mixing means and then dispensed from the device and applied to the consumer's hair by an application means.

The most common packaging device which can be used for the present invention involves storing the developer in a container such as a bottle, tube, aerosol, or a sachet and separately storing the dye lotion in an additional compartment within the developer container or more preferably in a separate container which may be identical such as a dual sachet or aerosol systems for example or different such as a bottle and tube system, Any combination may be used and is typically contingent on the type of composition being stored i.e. whether or not it is a thick or thin type.
The consumer or hair salon professional may mix the oxidizing component and the dye component by any means. This may simply involve the use of a mixing bowl into which the compositions are dispensed and then mixed, preferably using a mixing means such as a tool.
Alternatively, it may involve the addition of one of the compositions into the container of the other composition (typically the dye composition is added to the oxidizing composition), followed by manual shaking or mixing witri a toot. Another system involves the perforation or displacement of a seal located between the separate compartments of the dye and oxidizing composition within a single container or sachet followed by manual mixing within the container or in a separate and or additional container.
The devices described herein above can also be used in combination with a product delivery and or application tool to aid application of the product onto the hair. Again these devices may be of a very simple nature such as a nozzle attached to one of the containers or a separate applicator device such as a comb or brush. Such combs and brushes can be adapted in order to achieve particular effects, whether it may be quick and even coverage or root/hairline touch up, or highlights :or streaks. Alternatively, the container or one of the containers may be provided with a, comb attached to or instead of the dispensing nozzle whereby the product is dispensed through hollow tines and dispensing apertures located in the comb tines. The comb tines may be provided with single or multiple openings along the tines to improve product application and evenness especially root to tip, Product dispensation can be achieved by mechanical pressure applied to the container for example delaminating bottles or any of the mechanisms described hereinabove. The comb may be provided on the container such as to facilitate easy application and may be positioned vertically (so called verticomb) or at an angle to allow the consumer to access all areas, All devices may be designed to have utter-changeability, so that a range of different tools for hair application can be provided to the consumer.
The application devices may also include devices which assist in achieving particular effects such as highlighting such as highlighting combs, brushes and tools, fails and highlighting caps.
Highlighting devices comprising a hinged device into which an amount of composition is placed and then used to apply the composition to pre-determined /selected hair strands may also be used.
Additional device technology can he used to assist in the penetration of the product into the hair, Examples of such technology include heating devices, ultraviolet light devices and ultrasound devices.

Method of hair dyeing The hair coloring composition may be obtained by mixing immediately prior to use at least one tint (solid) composition and at least one developer (solid) composition. A
sufficient amount of the mixture is applied to the hair, according to the hair abundance, generally from about 60 to about 250 grams, Upon such preparation the. composition is applied to the hair to be dyed and remains in contact with the hair for an amount of time effective to dye the hair. Typically, the hair dye composition is allowed to act on the hair from about 2 to about 60, preferably about 15 to about 45, more preferably about 30 minutes, at a temperature ranging from 15 C to about 50 C. Thereafter, the hair is rinsed with water to remove the composition and dried. If necessary, the hair is washed with a shampoo and rinsed, e.g., with water or a weakly acidic solution, such as a citric acid or tartaric acid solution, and dried. Optionally, a separate conditioning product may also be provided.
fhe method of treating hair with the composition may therefore comprise the steps of.
(i) providing at least one tint (solid) composition comprising --- when dispersed/diluted/dissolved in a solvent such as water to form a tint premix the gel network thickening system and if present an alkalizing agent and oxidative precursor dyes and/or direct dyes;
(ii) providing a developer (solid) composition comprising an oxidizing agent, and optionally ---dispersing>diluting/dissolving it in a solvent such as water to form a developer premix;
(iii) mixing the developer (solid) composition or its premix with the dye (solid) composition or its premix to obtain a hair coloring composition;
(iv) applying the on-head composition for the oxidative dyeing of keratin fibers onto the hair.
The glycerol can be comprised in the dye composition or the developer composition or distributed in both components. Typically glycerol will be at least Comprised in the dye composition to serve as solvent for the dyes.
The method may further comprise waiting a period of time, typically between 2 minutes and 60 minutes, and then rinsing the hair coloring composition from the hair. The hair coloring composition can be applied on hair via applicator bottle or brush. It can be used on full head or partly on single strands (highlight application) as common highlight applicator foils, caps and special applicators can be used, but also freehand techniques such as balayage, with brush and/or combs can be possible. The composition can also be applied as a mousse via a manual spray, a pressurized container or an aerosol mousse. The composition may be dispensed as a solid form to which water is added to generate the oxidant and form a thickened vehicle suitable for hair coloring, Methods, systems and devices The composition is particularly suitable for use with the systems, methods and devices disclosed in W02012/127429.
