Description
METHOD FOR LIGHTENING KERATIN FIBRES EMPLOYING A COMPOSITION HAVING A BASIC PH COMPRISING ONE OR MORE SPECIFIC METAL COMPOUNDS FIELD OF THE INVENTION
The present invention relates to a method for lightening keratin fibres comprising a step of application of a composition having a basic pH comprising one or more specific metal compounds.
BACKGROUND OF THE INVENTION
When a person wishes to change head hair colour, in particular when he or she wishes to obtain a lighter colour than his or her original colour, it is often necessary to carry out, beforehand, head hair lightening or bleaching. To do this, lightening or bleaching products are used.
The lightening of head hair is evaluated by the "tone depth", which characterizes the degree or level of lightening. The notion of "tone" is based on the classification of natural shades, one tone separating each shade from the shade immediately following or preceding it. This definition and the classification of natural shades are well known to hairstyling professionals and are published in the book Sciences des traitements capillaires [The Science of Hair Care] by Charles Zviak, 1988, published by Masson, pp. 215 and 278.
The tone depths range from 1 (black) to 10 (very light blond), one unit corresponding to one tone; the higher the figure, the lighter the shade.
It is known practice to lighten or bleach head hair with lightening or bleaching compositions containing at least one chemical oxidizing agent, under alkaline pH conditions in the vast majority of cases. The role of this oxidizing agent is to degrade the melanin of head hair, which, depending on the nature of the oxidizing agent present and on the pH conditions, results in more or less pronounced lightening of the fibres. Thus, for relatively mild lightening, the oxidizing agent is generally hydrogen peroxide. When greater lightening is desired, in particular when the treated head hair is dark, use is normally made of persulfates in the presence of hydrogen peroxide. However, the lightening obtained by the action of such a combination is not always satisfactory because head hair with rather unattractive orangey-yellow shades which are very different from
natural shades is obtained, thereby complicating the subsequent colouring by limiting it to the obtaining of warm tones.
Thus, there exists a real need to develop a method for lightening keratin fibres, in particular dark keratin fibres, which makes it possible to obtain a satisfactory level of lightening with a decrease in the chromaticity of the lightened fibres and a less yellow, thus more natural, rendering. Such a method should resort to easy-to-use compositions which can optionally be used in combination with commercially available lightening compositions.
The applicant company has discovered, surprisingly, that all of these objectives can be achieved by the method according to the present invention.

The examples which follow serve to illustrate the invention without, however, exhibiting a limiting nature.
Example 1 (First embodiment of the invention) Four different locks of head hair a, b, a' and b' were prepared according to the preparation protocols described below.
Protocol for preparation of the lock a (P1)
A preparation obtained by mixing 10.8 g of bleaching powder based on persulfates, L'Oreal Professionnel Platifiz Precision, with 16.2 g of 20 volume oxidizing cream, L'Oreal Professionnel, was applied uniformly using a fine colouring brush to a lock of head hair, tone depth 2 (TD2), of 2.7 g positioned flat on an aluminium sheet placed on a heating plate maintained at a temperature of 33°C.
The preparation was left to stand for 30 minutes. The lock was subsequently rinsed with water, then a shampooing was subsequently carried out and, finally, the lock was combed and dried with a hair dryer.
Protocol for preparation of the lock b (P2)
The lock b was obtained from the lock a, which was treated a second time according to the protocol P1 described above. Thus, the lock b is a lock which has been subjected to two successive bleaching treatments.
Protocol for preparation of the lock a' (P3)
A preparation obtained by mixing 10.8 g of bleaching power based on persulfates, L'Oreal Professionnel Platifiz Precision, with 16.2 g of 20 volume oxidizing cream, L'Oreal Professionnel, and 3 g of a 60% by weight aqueous solution of ammonium zirconium carbonate of formula (NH4)2Zr(0H)2(C03)2 sold by Sigma-Aldrich under the reference 464597 was applied uniformly using a thin colouring brush to a lock of head hair (tone depth 2) of 2.7 g positioned flat on an aluminium sheet placed on a heating plate
maintained at a temperature of 33°C. The preparation was left to stand for 30 minutes. The lock was subsequently rinsed with water, then a shampooing was subsequently carried out and, finally, the lock was combed and dried with a hair dryer. Protocol for preparation of the lock b' (P4)
The lock b' was obtained from the lock a', which was treated a second time according to the protocol P3 described above. Thus, the lock b' is a lock which has been subjected to two successive bleaching treatments. Colorimetric measurements
The colour of the locks was evaluated in the CIE L* a* b* system, using a Minolta® CM 3600D spectrocolorimeter (illuminant D65).
In this L* a* b* system, L* represents the lightness, a* indicates the shade of the colour along the green/red colour axis and b* indicates the shade of colour along the blue/yellow colour axis. The higher the value of L, the lighter or less intense the colour. Conversely, the lower the value of L, the darker or more intense the colour. The higher the value of a*, the redder the shade, and the higher the value of b*, the yellower the shade.
The difference in the colour on head hair corresponds to the variation in colouration between the locks of head hair bleached with a bleaching composition and the locks of head hair bleached with the same bleaching composition which additionally comprises a metal compound C according to the present invention. This difference (DE) is measured according to the following equation:
in which: L*, a* and b* represent the values measured on a lock bleached once or twice with the bleaching composition comprising a metal compound C and U*, ao* and bo* represent the values measured on a lock bleached respectively once or twice with the same bleaching composition without metal compound C. The chromaticity is calculated according to the following formula:
The results of the colorimetric measurements are summarized in the following table:
[Table 1]
These results demonstrate that the addition of a metal compound C according to the present invention to the bleaching composition makes it possible to reduce the chromaticity, in particular the b* value, of a lock bleached once or twice and thus to obtain a satisfactory level of lightening with a less yellow, and thus more natural, rendering. Example 2 (Second embodiment of the invention)
Six different locks of head hair were prepared according to the preparation protocols described below.
Protocol for preparation of the locks 1 , 2 and 3 (P5) The locks 1, 2 and 3 were prepared according to the protocol (P1) of Example 1, except for the drying step, the protocol being carried out three times in succession. Thus, the three locks are therefore bleached three times in succession.
Protocol for preparation of the lock 4 - Application to wet head hair (P6) Immediately after the bleaching according to the protocol P5, 5.4 g of a 60% by weight aqueous solution of ammonium zirconium carbonate of formula (NH4)2Zr(OH)2(CC>3)2 at
pH 11 sold by Sigma-Aldrich under the reference 464597 were applied uniformly using a thin colouring brush to the still wet lock 1 positioned flat on an aluminium sheet.
The lock was subsequently kept flat in an oven at 80°C for 30 minutes. The lock was subsequently rinsed with water, then a shampooing (0.4 g of shampoo per gram of head hair) was subsequently carried out and, finally, the lock was combed and left to dry suspended in the open air.
Protocol for preparation of the lock 5 - Application to head hair dried with a hair dryer (P7) Immediately after the bleaching according to the protocol P5, the lock 2 was dried with a hair dryer and then 5.4 g of a 60% by weight aqueous solution of ammonium zirconium carbonate of formula (NH4)2Zr(OH)2(CC>3)2 at pH 11 sold by Sigma-Aldrich under the reference 464597 were applied uniformly using a thin colouring brush to the lock 2 positioned flat on an aluminium sheet. The lock was subsequently kept flat in an oven at 80°C for 30 minutes.
The lock was subsequently rinsed with water, then a shampooing (0.4 g of shampoo per gram of head hair) was subsequently carried out and, finally, the lock was combed and left to dry suspended in the open air. Protocol for preparation of the lock 6 - Application to head hair dried in the open air (P8)
Immediately after the bleaching according to the protocol P5, the lock 3 was left to dry in the open air and then, on the following day, 5.4 g of a 60% by weight aqueous solution of ammonium zirconium carbonate of formula (NH4)2Zr(OH)2(CC>3)2 at pH 11 sold by Sigma-Aldrich under the reference 464597 were applied uniformly using a thin colouring brush to the lock 3 positioned flat on an aluminium sheet.
The lock was subsequently kept flat in an oven at 80°C for 30 minutes.
The lock was subsequently rinsed with water, then a shampooing (0.4 g of shampoo per gram of head hair) was subsequently carried out and, finally, the lock was combed and left to dry suspended in the open air.
Colorimetric measurements
The colour of the locks was evaluated in the CIE L* a* b* system, using a Minolta® CM 3600D spectrocolorimeter (illuminant D65).
In this L* a* b* system, L* represents the lightness, a* indicates the shade of the colour
along the green/red colour axis and b* indicates the shade of colour along the blue/yellow colour axis. The higher the value of L, the lighter or less intense the colour. Conversely, the lower the value of L, the darker or more intense the colour. The higher the value of a*, the redder the shade, and the higher the value of b*, the yellower the shade. The difference in the colour on head hair corresponds to the variation in colouration between the locks of head hair bleached with a bleaching composition and the locks of head hair bleached with the same bleaching composition and then treated with a composition which comprises a metal compound C according to the present invention. This difference (DE) is measured according to the following equation:
in which:
L*, a* and b* represent the values measured on a lock bleached with the bleaching composition and then treated with a composition which comprises a metal compound C according to the present invention and U*, ao* and bo* represent the values measured on a lock bleached with the bleaching composition but untreated with the composition which comprises a metal compound C according to the present invention.
The chromaticity is calculated according to the following formula:
The results of the colorimetric measurements are summarized in the following table:
[Table 2]
These results demonstrate that the use of a composition according to the present invention comprising a metal compound C in post-treatment of a method for bleaching keratin fibres makes it possible to reduce the chromaticity, in particular the b* value, of a bleached lock and thus to obtain a satisfactory level of lightening with a less yellow and thus more natural rendering, it not mattering much if the post-treatment is carried out on a wet lock or on a lock dried with a hair dryer or in the open air.
Example 3 (Second embodiment of the invention)
Four different locks of head hair were prepared according to the preparation protocols described below.
Protocol for preparation of the locks 8 and 9 (P9)
A preparation obtained by mixing 8 g of bleaching powder based on persulfates, L'Oreal Professionnel Blond Studio Multi-Techniques 8, with 16 g of 30 volume oxidizing cream, L'Oreal Professionnel Blond Studio, was applied uniformly using a fine colouring brush all along a lock of head hair, tone depth 2 (TD2), of 2.7 g positioned flat on an aluminium sheet placed on a heating plate maintained at a temperature of 33°C. The preparation was left to stand for 50 minutes. The lock was subsequently rinsed with water and then a shampooing (0.4 g of shampoo per gram of head hair) was subsequently carried out. The lock was subsequently combed.
Protocol for preparation of the lock 10 - zirconium(IV) chloride (P10)
Immediately after the bleaching according to the protocol P9, 5.4 g of a solution of zirconium(IV) chloride (ZrCL) at 15% by weight in water prepared from zirconium chloride sold by Sigma-Aldrich under the reference 221880 at pH 11 with addition of aqueous ammonia were applied uniformly using a thin colouring brush to the still wet lock 8 positioned flat on an aluminium sheet.
The lock was subsequently kept flat in an oven at 80°C for 30 minutes.
The lock was subsequently rinsed with water, then a shampooing (0.4 g of shampoo per gram of head hair) was subsequently carried out and, finally, the lock was combed and left to dry suspended in the open air. Protocol for preparation of the lock 11 - zirconium(IV) acetate hydroxide (P11)
Immediately after the bleaching according to the protocol P9, 5.4 g of a solution of zirconium(IV) acetate hydroxide at 15% by weight in water prepared from zirconium(IV) acetate hydroxide ((CH3C02)xZr(0H)y with x+y = 4) sold by Sigma-Aldrich under the reference 464600 at pH 11 with addition of aqueous ammonia were applied uniformly using a thin colouring brush to the still wet lock 9 positioned flat on an aluminium sheet. The lock was subsequently kept flat in an oven at 80°C for 30 minutes.
The lock was subsequently rinsed with water, then a shampooing (0.4 g of shampoo per gram of head hair) was subsequently carried out and, finally, the lock was combed and left to dry suspended in the open air.
Colorimetric measurements
The colour of the locks was evaluated in the CIE L* a* b* system, using a Minolta® CM 3600D spectrocolorimeter (illuminant D65).
In this L* a* b* system, L* represents the lightness, a* indicates the shade of the colour along the green/red colour axis and b* indicates the shade of colour along the blue/yellow colour axis. The higher the value of L, the lighter or less intense the colour. Conversely, the lower the value of L, the darker or more intense the colour. The higher the value of a*, the redder the shade, and the higher the value of b*, the yellower the shade.
The difference in the colour on head hair corresponds to the variation in colouration between the locks of head hair bleached with a bleaching composition and the locks of head hair bleached with the same bleaching composition and then treated with a composition which comprises a metal compound C according to the present invention. This difference (DE) is measured according to the following equation:
in which:
L*, a* and b* represent the values measured on a lock bleached with the bleaching composition and then treated with a composition which comprises a metal compound C according to the present invention and U*, ao* and bo* represent the values measured on
a lock bleached with the bleaching composition but untreated with the composition which comprises a metal compound C according to the present invention.
The chromaticity is calculated according to the following formula:
The results of the colorimetric measurements are summarized in the following table:
[Table 3]
These results demonstrate that the use of a composition according to the present invention comprising a metal compound C in post-treatment of a method for bleaching keratin fibres makes it possible to reduce the chromaticity, in particular the b* value, of a bleached lock and thus to obtain a satisfactory level of lightening with a less yellow and thus more natural rendering.
