                    The present invention relates to a composition for lightening keratin fibres, comprising at least one chemical oxidizing agent, at least one (bi)carbonate, at least one silicate, at least one compound chosen from esters and/or amides and/or imines and at least one compound chosen from alcohols, amphoteric or zwitterionic compounds, organic acids, alkanes and/or alkenes and/or ethers and mixtures thereof, and also to a process for lightening keratin fibres using said composition.
When a person wishes to change hair colour, notably when he or she wishes to obtain a lighter colour than their original colour, it is often necessary to perform preliminary lightening or bleaching of the hair. 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, pages 215 and 278.
The tone levels 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 the 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 the hair, which, depending on the nature of the oxidizing agent present and of the pH conditions, leads to 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, notably when the hair treated is dark, persulfates are usually used in the presence of hydrogen peroxide. However, the lightening obtained by the action of such a combination is not always satisfactory, since it produces hair with unattractive yellow-orange shades that are far removed from the natural shades, which complicates subsequent dyeing by limiting it to the production of warm tones. Furthermore, persulfate-based lightening compositions may lead to a deterioration of the fibre quality. Furthermore, persulfate-based compositions are generally not chemically compatible with the presence of oxidation dyes and/or direct dyes in order to be able to bleach the hair fibre and to dye it in a single step. Thus, when it is desired to simultaneously bleach and dye keratin fibres, a two-step process is used with a first step of bleaching the keratin fibres followed by a second step of dyeing the keratin fibres using a dye composition comprising one or more direct dyes and/or one or more oxidation dyes.
Thus, there is a real need to develop a composition which allows effective lightening of keratin fibres, notably dark keratin fibres, with a less yellow and more natural result. Such a composition should also be more respectful of the quality of the fibres, notably by minimizing their degradation. Finally, such a composition should also be compatible with the presence of direct dyes and/or oxidation dyes so as to obtain good colour buildup, intense and chromatic colours and also allow a wider range of colours to be obtained.
The Applicant has discovered, surprisingly, that all or some of these objectives can be achieved by means of the composition according to the present invention.
According to a first aspect, a subject of the present invention is a composition comprising:
in which:
According to a second aspect, a subject of the present invention is a process for lightening keratin fibres, comprising the application to the keratin fibres of a composition comprising ingredients i) to iv) and iv′) as defined previously.

According to a first aspect, a subject of the present invention is a composition comprising ingredients i) to iv) and iv′) as defined previously.
The Applicant found, surprisingly, that the composition according to the present invention allowed effective lightening of keratin fibres with a less yellow and more natural result. When the colour of keratin fibres treated with the composition according to the invention is compared with the colour of keratin fibres treated with lightening compositions known in the art, b* values measured in the CIE L* a* b* system are observed to be lower for the composition according to the invention than for lightening compositions known in the art at an equivalent intensity level L*.

10 g of each of the compositions C13 to C19 are applied to seven 1-g locks of Caucasian HT4 dark hair on a hot plate maintained at a temperature of 33° C. The whole is covered with a cellophane film for 50 minutes.
The locks are then rinsed, washed with a standard shampoo, rinsed again and then dried.
The results of the colorimetric measurements are summarized in the following table:
  
    
      
        
        
        
        
        
          
            
            
          
          
            
            
          
          
            
            
            
            
          
          
            
            
          
        
        
          
            
          
        
      
      
        
        
        
        
        
          
            
            
            
            
          
          
            
            
            
            
          
          
            
            
            
            
          
          
            
            
            
            
          
          
            
            
            
            
          
          
            
            
            
            
          
          
            
            
            
            
          
          
            
            
          
        
      
    
  
The results show that compositions according to the invention make it possible to obtain a good level of lightening characterized by relatively high L* values. Furthermore, the colour shades obtained are characterized by lower b* values at an equivalent L* intensity level for the compositions according to the present invention than for the comparative persulfate-based compositions of Example 1, as illustrated in
