However, there remains the need for a colourant that can be used routinely and which delivers an effective level of colouring to hair. Furthermore, it is often desired to introduce red/mahogany shades into blue-blacks, because this better reflects the natural shade of human hair. Surprisingly, we have found this may be achieved by mixing low levels Cu(ll) with Fe(ll) or Fe(lll), whilst maintaining a high depth of shade,.

Further Ingredients Cationic Polymers Cationic polymers are preferred ingredients in a shampoo composition of the invention for enhancing performance.
Suitable cationic polymers may be homopolymers which are cationically substituted or may be formed from two or more types of monomers. The weight average (Mw) molecular weight of the polymers will generally be between 100 000 and 2 million daltons. The polymers will have cationic nitrogen containing groups such as quaternary ammonium or protonated amino groups, or a mixture thereof. If the molecular weight of the polymer is too low, then the conditioning effect is poor. If too high, then there may be problems of high extensional viscosity leading to stringiness of the composition when it is poured.
The cationic nitrogen-containing group will generally be present as a substituent on a fraction of the total monomer units of the cationic polymer. Thus when the polymer is not a homopolymer it can contain spacer non-cationic monomer units. Such polymers are described in the CTFA Cosmetic Ingredient Directory, 3rd
edition. The ratio of the cationic to non-cationic monomer units is selected to give polymers having a cationic charge density in the required range, which is generally from 0.2 to 3.0 meq/gm. The cationic charge density of the polymer is suitably determined via the Kjeldahl method as described in the US
Pharmacopoeia under chemical tests for nitrogen determination.
Suitable cationic polymers include, for example, copolymers of vinyl monomers having cationic amine or quaternary ammonium functionalities with water soluble spacer monomers such as (meth)acrylamide, alkyi and dialkyi (meth)acrylamides, alkyi (meth)acrylate, vinyl caprolactone and vinyl pyrrolidine. The alkyi and dialkyi substituted monomers preferably have C1 -C7 alkyi groups, more preferably C1 -3 alkyi groups. Other suitable spacers include vinyl esters, vinyl alcohol, maleic anhydride, propylene glycol and ethylene glycol. The cationic amines can be primary, secondary or tertiary amines, depending upon the particular species and the pH of the composition. In general secondary and tertiary amines, especially tertiary, are preferred.
Amine substituted vinyl monomers and amines can be polymerized in the amine form and then converted to ammonium by quaternization.
The cationic polymers can comprise mixtures of monomer units derived from amine- and/or quaternary ammonium-substituted monomer and/or compatible spacer monomers.
Suitable cationic polymers include, for example: cationic diallyl quaternary ammonium-containing polymers including, for example, dimethyldiallylammonium chloride homopolymer and copolymers

A particularly suitable type of cationic polysaccharide polymer that can be used is a cationic guar gum derivative, such as guar hydroxypropyltrimethylammonium chloride (commercially available from Rhodia in their JAGUAR trademark series). Examples of such materials are JAGUAR C13S, JAGUAR C14, JAGUAR C15, JAGUAR C17 and JAGUAR C16 Jaguar CHT and JAGUAR C162. Mixtures of any of the above cationic polymers may be used.

Cationic conditioning surfactants
Conditioner compositions will typically comprise one or more conditioning surfactants which are cosmetically acceptable and suitable for topical application to the hair. Suitable conditioning surfactants include those selected from cationic surfactants, used singly or in admixture. Preferably, the cationic surfactants have the formula N+R1R2R3R4 wherein R1, R2, R3 and R4 are independently (Ci to C30) alkyl or benzyl. Preferably, one, two or three of R1, R2, R3 and R4 are independently (C4 to C30) alkyl and the other R1, R2, R3 and R4 group or groups are (C-i-Ce) alkyl or benzyl. More preferably, one or two of R1, R2, R3 and R4 are independently (C6 to
C30) alkyl and the other R1 , R2, R3 and R4 groups are (Ο-ι-Οβ) alkyl or benzyl groups. Optionally, the alkyl groups may comprise one or more ester (-OCO- or - COO-) and/or ether (-O-) linkages within the alkyl chain. Alkyl groups may optionally be substituted with one or more hydroxyl groups. Alkyl groups may be straight chain or branched and, for alkyl groups having 3 or more carbon atoms, cyclic. The alkyl groups may be saturated or may contain one or more carbon- carbon double bonds (e.g. oleyl). Alkyl groups are optionally ethoxylated on the alkyl chain with one or more ethyleneoxy groups. Suitable cationic surfactants for use in conditioner compositions according to the invention include cetyltrimethylammonium chloride, behenyltrimethylammonium chloride, cetylpyridinium chloride, tetramethylammonium chloride,

Further suitable cationic surfactants include those materials having the CTFA designations Quaternium-5, Quaternium- 31 and Quaternium-18. Mixtures of any of the foregoing materials may also be suitable. A particularly useful cationic surfactant for use in conditioners according to the invention is cetyltrimethylammonium chloride, available commercially, for example as GENAMIN CTAC, ex Hoechst Celanese. Another particularly useful cationic surfactant for use in conditioners according to the invention is
behenyltrimethylammonium chloride, available commercially, for example as GENAMIN KDMP, ex Clariant.
Another example of a class of suitable cationic surfactants for use in the invention, either alone or together with one or more other cationic surfactants, is a
combination of (i) and (ii) below:
(i) an amidoamine corresponding to the general formula (I):
R1CO
(ii) in which R1 is a hydrocarbyl chain having 10 or more carbon atoms, R2 and R3 are independently selected from hydrocarbyl chains of from 1 to 10 carbon atoms, and m is an integer from 1 to about 10; and
(iii) an acid. As used herein, the term hydrocarbyl chain means an alkyl or alkenyl chain.
Preferred amidoamine compounds are those corresponding to formula (I) in which
R1 is a hydrocarbyl residue having from about 1 1 to about 24 carbon atoms, R2 and R3 are each independently hydrocarbyl residues, preferably alkyl groups, having from 1 to about 4 carbon atoms, and m is an integer from 1 to about 4.
Preferably, R2 and R3 are methyl or ethyl groups. Preferably, m is 2 or 3, i.e. an ethylene or propylene group.
Preferred amidoamines useful herein include stearamido-propyldimethylamine, stearamidopropyldiethylamine, stearamidoethyldiethylamine,
stearamidoethyldimethylamine, palmitamidopropyldimethylamine,
palmitamidopropyl-diethylamine, palmitamidoethyldiethylamine, palmitamidoethyldimethylamine, behenamidopropyldimethyl-amine,
behenamidopropyldiethylmine, behenamidoethyldiethyl-amine,
behenamidoethyldimethylamine, arachidamidopropyl-dimethylamine,
arachidamidopropyldiethylamine, arachid-amidoethyldiethylamine,
arachidamidoethyldimethylamine, and mixtures thereof.
Particularly preferred amidoamines useful herein are
stearamidopropyldimethylamine, stearamidoethyldiethylamine, and mixtures thereof.
Commercially available amidoamines useful herein include:
stearamidopropyldimethylamine with tradenames LEXAMINE S-13 available from Inolex (Philadelphia Pennsylvania, USA) and AMIDOAMINE MSP available from Nikko (Tokyo, Japan), stearamidoethyldiethylamine with a tradename
AMIDOAMINE S available from Nikko, behenamidopropyldimethylamine with a tradename INCROMINE BB available from Croda (North Humberside, England), and various amidoamines with tradenames SCHERCODINE series available from Scher (Clifton New Jersey, USA).
A protonating acid may be present. Acid may be any organic or mineral acid which is capable of protonating the amidoamine in the conditioner composition. Suitable acids useful herein include hydrochloric acid, acetic acid, tartaric acid, fumaric acid, lactic acid, malic acid, succinic acid, and mixtures thereof.
Preferably, the acid is selected from the group consisting of acetic acid, tartaric acid, hydrochloric acid, fumaric acid, lactic acid and mixtures thereof.
The primary role of the acid is to protonate the amidoamine in the hair treatment composition thus forming a tertiary amine salt (TAS) in situ in the hair treatment
composition. The TAS in effect is a non-permanent quaternary ammonium or pseudo-quaternary ammonium cationic surfactant.
Suitably, the acid is included in a sufficient amount to protonate more than 95 mole% (293 K) of the amidoamine present.
In conditioners of the invention, the level of cationic surfactant will generally range from 0.01 % to 10%, more preferably 0.05 % to 7.5%, most preferably 0.1 % to 5% by weight of the composition.
Conditioners of the invention will typically also incorporate a fatty alcohol. The combined use of fatty alcohols and cationic surfactants in conditioning
compositions is believed to be especially advantageous, because this leads to the formation of a lamellar phase, in which the cationic surfactant is dispersed.
Representative fatty alcohols comprise from 8 to 22 carbon atoms, more preferably 16 to 22. Fatty alcohols are typically compounds containing straight chain alkyl groups. Examples of suitable fatty alcohols include cetyl alcohol, stearyl alcohol and mixtures thereof. The use of these materials is also
advantageous in that they contribute to the overall conditioning properties of compositions of the invention.
The level of fatty alcohol in conditioners of the invention will generally range from 0.01 wt% to 10 wt%, preferably from 0.1 wt% to 8 wt%, more preferably from 0.2 wt% to 7 wt%, most preferably from 0.3 wt% to 6 wt% by weight of the
composition. The weight ratio of cationic surfactant to fatty alcohol is suitably from 1 : 1 to 1 : 10, preferably from 1 : 1 .5 to 1 :8, optimally from 1 :2 to 1 :5. If the weight ratio of cationic surfactant to fatty alcohol is too high, this can lead to eye irritancy from the composition. If it is too low, it can make the hair feel squeaky for some consumers.
Adjuncts
The compositions of the present invention may also contain adjuncts suitable for hair care. Generally such ingredients are included individually at a level of up to 2 wt%, preferably up to 1 wt% of the total composition.
Suitable hair care adjuncts, include amino acids, sugars and ceramides and viscosity modifiers. Method of use
The method of colouring hair comprises the steps of applying to hair sequentially in any order:
(i) a composition comprising a mixture of metal ion Fe(ll), Fe(lll) and
Cu(ll) and/or complex where the wt fraction of Cu/Fe is from 0.1 to 5; and
(ii) a second composition, which comprises from 0.05 wt% to 10wt% of a polyphenol comprising gallic acid or short chain esters thereof Preferably, the compositions of the invention are applied to wet hair, necessitating the step of wetting the hair before application of the compositions of the invention.
Preferably, the method comprises the step of rinsing hair between application of the first composition and the second composition (ii). It is highly preferred if the hair is rinsed after application of both compositions of the invention.
It is preferred if the first composition to be applied is a shampoo composition, a more preferred system is that the first application is a shampoo composition followed by application of a conditioner composition.
Further conditioning and/or styling products may be applied as part of the colouring process.
The level of each composition applied to the head of hair is preferably from 5g to 100g.
Preferably, each composition remains on the hair for 5 to 600 seconds, more preferably 10 to 300 seconds. Preferably, the water used to wet and rinse the hair has a French hardness of from 0 to 36 degrees, more preferably 0 to 24 degrees, most preferably from 0 to 2 degrees.
Preferably, the water used to wet and rinse the hair contains less than 1 ppm of chlorine based bleaching agents such as chlorine dioxide or hypochlorite. Most preferably less than 50ppb .
Examples A 0.7g twice bleached platinum blonde hair switch was bathed for 300 seconds in a solution containing 0.5wt% of metal sulphonate and 2wt% of sodium gluconate. The switch was removed and rinsed for 30 seconds before being places in a 0.5wt% solution of polyphenol for 300 seconds, removed rinsed and dried. The colour of the switch was measured using a reflectometer (Color \7) and expressed as the CIE L* and hue angle values. L* measure the depth of shade and the hue angle measures the colour. All water used was demineralised. The metal sulphonate used was selected from mixtures of CuS04 and FeS04 and the polyphenol from gallic acid and tannic acid. All materials were used as received from Aldrich. The wt% of Cu(ll) and Fe(ll) in the metal bath were calculated from the known weights and purities. The results are shown below.

2.09 0.00 - 39.4 76.0 50.2 99.6
A hue angle of 270 represent blue, 0 (360) is red, 90 is yellow and 180 is
The untreated hair had an L* of 63.0 and a hue angle of 76.0. Reference treatment with one metal only, are given in italics.
It is desirable to have a dark colour with a red/blue hue, thus a low L* value and a hue value of 250 to 360. The results above demonstrate that the effect of changing the Cu/Fe ratio is more desirable for gallic acid than tannic acid. Addition of even low levels of Cu to the tannic acid leads to an immediate drop in L* unlike Gallic acid. Addition of low levels of Cu to tannic acid leads to yellowing of the hair, with the hue angle approaching 90 (yellow). Addition of low levels of Cu to gallic acid adds to the red component.
The desired depth of shade and hue is obtained by a combination of Fe(ll) with Cu(ll). The Cu/Fe wt fraction of 0.85 and 1 .92 with gallic acid, give the best results.
