Their molecular mass may vary, for example, from 1500 to 10 000 and in particular from 2000 to 5000 approximately. Among these compounds, mention may be made especially of:

products sold under the name Quat-Pro E by the company Maybrook
and referred to in the CTFA dictionary as Triethonium Hydrolyzed
Collagen Ethosulfate,

The cosmetic composition according to the present invention may further comprise one or more silicone(s) additional to the silicones contained in the oil-in-water emulsion (a). These silicones are referred to “additional silicones”.

The additional silicones are different from the silicone surfactants (b).
Such additional silicones are preferably chosen from non-amino

Method of measure of extraction of dyes
Extraction of acid dyes from hair swatches using Milli-Q water at 80°C with constant stirring and quantifying the extract by reverse phase gradient high performance liquid chromatography (HPLC) equipped with photo diode Array (PDA) detector.
The hair swatches were cut into pieces and about 400 mg of these hair samples were weighed out accurately and transferred to a

100 mL beaker. To this add 20 ml of water and stir the sample on magnetic stirrer at 80°C for 30 min at 200 RPM. The extract from the beaker were transferred to a 100mL volumetric flask and leaving the hair samples in the beaker. The extraction was repeated for 3 more cycles using 20 mL Milli-Q water for each cycle. The final volume was adjusted to 100ml using water. The above solutions were centrifuged at 14,000 rpm for 5 minutes followed by transferring 1mL each of the clear supernatants to a 1.5 mL HPLC vial for HPLC analysis.

The compositions (A) and (C) and the compositions (A) and (C1) were separately pre-mixed in a 1:1 ratio before application on 90% grey Indian natural hair. The quantity applied per gram of lock is mentioned in table below. After a leave-on time of 3 minutes, the locks were washed with a shampoo, rinsed with water and then dried. This study was done on 3 locks.

b. Protocol

The compositions (A) and (C) and the compositions (B4) and (C) were pre-mixed in a 1:1 ratio before application. The mixtures (A+C) and (B4+C) thus obtained were then applied on locks of 90% grey Indian natural hair in a quantity of 0,4g of composition per gram of lock.
After a leave-on time of 3 minutes, the locks were washed with a shampoo, rinsed with water and then dried. This protocol was repeated 5 times.
The total dyes deposition was then measured by a HPLC according to the protocol described previously “Method of measure of extraction of dyes”. This measurement was repeated 3 times for each sample corresponding to mixtures (A+C) and (B4+C).

The results show that the composition according to the present invention (A), i.e. comprising the specific silicone emulsion, leads to a significantly higher dyes deposition than a comparative composition (B4) missing said emulsion. Indeed, after five successive applications, the amount of dyes deposited by the claimed composition (A) on the hair is almost twice as high as the amount of dyes deposited by the comparative composition (B4).
Example 5

a. Compositions
The compositions A (invention) and B2 and B3 (comparative) were prepared from the ingredients indicated, in percentage by active matter, in the table mentioned above at example 3. In addition, the conditioning composition C was prepared from the ingredients indicated, in percentage by active matter, in the table mentioned above at example 1.
The compositions A and C were then pre-mixed in a 1:1 ratio before application.
b. Protocol
At the time of use, locks of 90% grey Indian natural hair were first washed with the composition C1 (prepared from the ingredients indicated, in percentage by active matter, in the table mentioned above at example 3) and then the different compositions (A+C), B2 and B3 were applied for colour measurements on these cleaned locks of hair.
The ready to use compositions (A+C), B2 and B3 were applied on the locks in quantity of 0.4g of composition per gram of lock. After a leave-on time of 3 minutes, the locks of hair were rinsed with water and dried. This protocol was repeated 3 and 5 times and 6 locks of hair were used for each composition (A+C), B2 or B3.
The evaluation of the coloration has been read on a spectrocolorimeter (Kinoca 2600D instrument) for the colorimetric measurements. In this system, L* represents
the intensity of the color, a* indicates the green/red color axis and b* indicates the blue/yellow color axis.
The lower the value of L, the darker or more intense the color. The higher the value of a*, the redder the shade; the higher the value of b*, the yellower the shade. The variation in coloring between the colored locks of natural hair (NW) which is untreated (control) and after coloration are defined by AE*, corresponding to the color uptake on keratin fibers, according to the following equation:

In this equation, represent the values measured
after dyeing the locks and represent the values
measured for the untreated 90% grey Indian natural locks.

The greater the value of AE*, the greater the difference in color between the control locks and the dyed locks and the greater color uptake is.
c. Results
The results thus obtained are given in the table below (average for 6 locks).

5 applications 5.46
The results thus obtained show that the composition according to the present invention, i.e. comprising the combination of a specific silicone emulsion and a silicone surfactant, leads to a progressive coloration. Indeed, the colour uptake increases significantly after each application, meaning that dyes deposition from the previous application remains on the hair and adds up to the next dyes deposition.
In addition, the claimed composition provides a better colour uptake than comparative composition lacking the specific combination.
Moreover, a qualitative study with 70% grey hair men and women showed that there was a visible colour uptake with first usage of the composition (A) according to the present invention and progressive grey coverage until five washes, without visible stains on the hand.
