COMPLETE SPECIFICATION
The following specification particularly describes the invention and the manner in which it
is to be performed.

The present invention relates to a cosmetic composition for treating keratin fibres, and in particular human keratin fibres such as hair, which comprises one or more polymers comprising at least one cationic or quaternized (meth)acrylamide unit, a specific oil-in-water-type silicone emulsion, and one or more surfactants.
The invention also relates to a cosmetic process for washing and/or conditioning keratin fibres using this composition.
Finally, the invention relates to the use of such a composition for washing and/or conditioning keratin fibres.
It is common practice to use detergent cosmetic compositions such as shampoos and shower gels, based essentially on surfactants, for washing keratin materials especially such as the hair and the skin. These compositions are applied to the keratin materials, which are preferably wet, and the lather generated by massaging or rubbing with the hands or a toiletry flannel makes it possible, after rinsi ng with water, to remove the diverse types of soiling initially present on the hair or the skin.
These compositions contain substantial contents of "detergent" surfactants, which, in order to be able to formulate cosmetic compositions with good washing power, must especially give them good foaming power.
The surfactants that are useful for this purpose are generally of anionic, nonionic and/or amphoteric type, and particularly of anionic type.
These compositions have generally a good washing power, but the intrinsic cosmetic properties associated with them nevertheless remain fairly poor, owing in particular to the fact that the relatively aggressive nature of such a cleaning treatment can, in the long run, lead to more or less pronounced damage to the hair fibre, this damage being associated in particular with the gradual removal of the lipids or proteins contained in or on the surface of this fibre.

Thus, in order to improve the cosmetic properties of the above detergent compositions, and more particularly those which are to be applied to sensitized hair (i.e. hair which has been damaged or made brittle, in particular under the chemical action of atmospheric agents and/or hair treatments such as permanent-waving, dyeing or bleaching), it is now common to introduce additional cosmetic agents known as conditioners into these compositions. These conditioners are intended mainly to repair or limit the harmful or undesirable effects induced by the various treatments or aggressions to which the hair fibres are subjected more or less repeatedly. They may, of course, also improve the cosmetic behaviour of natural hair.
The conditioners most commonly used to date in shampoos include cationic polymers, silicones and/or silicone derivatives, which give washed, dry or wet hair an ease-of disentangling, softness and smoothness which are markedly better than that which can be obtained with corresponding cleaning compositions from which they are absent.
In particular, it is known to use a mixture of silicone and cationic polymer. However, the compositions containing them still have numerous disadvantages, such as leading to an insufficient deposit of silicones on hair and impacting therefore strongly on their cosmetic properties.
Thus, there is a real need to provide cosmetic compositions, such as compositions for washing and/or conditioning keratin fibres, and in particular human keratin fibres, that allow overcoming the drawbacks described above, i.e. which effectively remove dirt and excess sebum and enhance cosmetic properties of said fibres, such as softness, smoothness, manageability and disentangling. These cosmetic properties may also be long-lasting.
The composition should give satisfactory silicone deposit on the keratin fibres.
The Applicant has now discovered that a cosmetic composition comprising one or more polymers comprising at least one cationic or quaternized (meth)acrylamide unit, a specific oil-in-water-type silicone emulsion, and one or more surfactants makes it possible to achieve the objectives outlined above.

Thus, the subject of the invention is especially a cosmetic composition comprising:
a. one or more polymers comprising one or more cationic or
quaternized acrylamide and/or methacrylamide unit(s);
b. an oil-in-water emulsion having D50 particle size of less than
350 nm and comprising:
- a silicone mixture comprising (i) a trialkylsilyl terminated dialkylpolysiloxane having a viscosity of from 40,000 to less than 100,000 mPa.s at 25°C and (ii) an amino silicone having a viscosity of from 1,000 to 15,000 mPa.s at 25°C and an amine value of from 2 to 10 mg of KOH per gram of amino silicone,
- a mixture of emulsifiers comprising one or more nonionic emulsifiers, wherein the mixture of emulsifiers has a HLB value of from 10 to 16, and
- water;
c. one or more surfactants.
This cosmetic composition, when applied on keratin fibres, in particular human keratin fibres such as hair, leads to an improvement of the condition and quality of hair, in terms of hair feel (e.g. smooth feel, soft feel, conditioned feel) and hair manageability (e.g., no or less frizz, styleability/shapeability, combing, detangling, desirable volume).
This cosmetic composition allows increasing the silicone deposition on hair when compared to a similar composition which does not contain the specific polymer a.
The composition according to the invention may optionally comprise one or more direct dye and/or pigment. In that option, the cosmetic composition allows increasing the silicone and dyes deposition on hair.
The present invention also relates to a cosmetic treatment process, in particular for washing and/or conditioning keratin fibres, preferably human keratin fibres such as the hair, using this composition.

Another subject-matter of the invention is the use of the
composition according to the invention for washing and/or
conditioning keratin fibres.

Particle size measurement
Emulsion particle size is measured by using a device ZetaSizer from Malvern, UK, model Nano-ZS which is based on the Photon Correlation Spectroscopy (PCS) method. The D50 value of particle size (average hydrodynamic particle diameter) is measured, wherein the evaluating algorithm is “cumulants analysis”.
Take 0.5 g of the emulsion sample in a 250 ml beaker, 100 ml of demineralized water is poured into it and then mixed properly to get the sample test solution. The sample test solution is poured in the cuvette cell and is put into the slot of the instrument to measure the particle size of the emulsion. D50 is defined as the value of the particle diameter at 50% in the cumulative distribution. For example, if D50=170 nm, then 50% of the particles in the sample are larger than 170 nm, and 50% smaller than 170 nm or about 50% by volume of all droplets in said emulsion is 170 nm.

Viscosity measurement
The viscosity, especially of the silicones or of the emulsion, is measured at 25°C.
For viscosities between 1000 to 40,000 mPa.s at 25ºC: the viscosity could be measured with an Anton Paar Rheometer; model MCR101, geometry single gap cylinder: CC27 spindle and shear rate of for 2 minutes, at 25°C.
For viscosities between 40,000 to 100,000 mPa.s at 25ºC: the viscosity could be measured with an Anton Paar Rheometer; model MCR101, 25-6 cone (Cone-plate geometry: 25 mm dia. / 6° cone); the “Zero gap” setting being made and with a shear rate of for 2
minutes, at 25°C.
Three measurements are made for each sample and the viscosity value is taken at 60 seconds. MCR Rheometer Series products work as per USP (US Pharmacopeia Convention) 912 – Rotational Rheometer methods.
Amine value measurement
The amine value is determined by acid-base titration using a potentiometer [Make: Veego; Model: VPT-MG]. 0.6 g of sample is taken in a 500 ml beaker and a toluene-butanol 1:1 mixture is added and stirred to mix the sample thoroughly; then the sample soluti on is titrated with a 0.1(N) HCl solution. A determination of the blank value with the toluene-butanol 1:1 mixture is also done. The calculation of the amine value is done by the above mentioned potentiometer.
The amine value is calculated according to the formula:

where V= Volume of HCl required in ml, VBlank= Volume of HCl for blank value (without sample) with the toluene-butanol 1:1 mixture in ml; N= Normality of HCl, i.e. 0.1 N, W= weight of the sample taken in gram.
HLB Value
The term HLB is well known to those skilled in the art, and denotes the hydrophilic-lipophilic balance of a surfactant or

emulsifier. In the present invention, HLB values refer to the values at 25°C.
The HLB can be measured by experimental determination or can be calculated.
Calculation of HLB value of nonionic surfactans is calculated according to the equation with E being the weight
percentage of oxyethylenecontent and P being the weight percentage of polyhydric alcohol content, described in to the publication Griffin, J. Soc. Cosm. Chem. 1954 (vol.5, n°4), pp.249-256.
It can also experimentally be determined according to the book of F. Puisieux and M. Seiller, entitled "Galenica 5: Les systèmes disperses - Tome I - Agents de surface et émulsions - Chapitre IV -Notions de HLB et de HLB critique, pp.153-194 - paragraph 1.1.2. Determination de HLB par voie experimentale [Experimental determination of HLB], pp.164-180".
The calculated HLB is the preferred HLB values that should be taken into account.
Said calculated HLB could be defined as being the following:
“calculated molar mass of the hydrophilic
part/total molar mass.”
For an oxyethylenated fatty alcohol, the hydrophilic part corresponds to the oxyethylene units condensed onto the fatty alcohol and the “calculated HLB” then corresponds to the “Griffin HLB” as defined hereabove.
For an ester or an amide, the hydrophilic part is naturally defined as being beyond the carbonyl group, starting from the fatty chain(s).
For ionic surfactants/emulsifiers, the HLB value of individual
surfactant/emulsifier can be calculated applying the Davies formula as
described in Davies JT (1957), "A quantitative kinetic theory of
emulsion type, I. Physical chemistry of the emulsifying agent",
Gas/Liquid and Liquid/Liquid Interface (Proceedings of the
International Congress of Surface Activity): 426-438.
According to the formula, the HLB is derived by summing the hydrophilic/hydrophobic contribution afforded by the structural

components of the emulsifier: HLB = (hydrophilic groups numbers) – n(group number per group) +7.
Approximate HLB values for some cationic emulsifiers are given in Table IV, in “Cationic emulsifiers in cosmetics”, GODFREY, J. Soc. Cosmetic Chemists (1966) 17, pp17-27.
When two emulsifiers A and B of known HLB are blended for use, the is said to be the required HLB for the mixture. This is
expressed by the equation
where = the amount (weight) of the first emulsifier (A)
used, and = the amount (weight) of the second emulsifier (B);
= the assigned HLB values for emulsifiers A and B; = the HLB of the mixture. Said oil-in-water emulsion is for example described in WO 2017/108824.

maintained till both emulsifiers became liquid. Then 31 g of trideceth-3 and 350 g of trideceth-10 (80% of active material) were added. These nonionic emulsifiers mixture had an HLB value = 11.25.
Then 80 g water and 6.2 g glacial acetic acid were added to the
tank and the mixing started. The mixing was continued till whole mass
became a creamy paste. The whole paste was introduced in the
emulsion tank. Homogenization was carried out for 30 minutes at room
temperature. 79.6 g demineralized water were added and
homogenization was carried out for 60 minutes. 72.7 g demineralized water were added and homogenization was carried out for 50 minutes. 197.4 g demineralized water were added and homogenization was carried out for 5 minutes. 294.3 g demineralized water were added and homogenization was carried out for 5 minutes. 180 g demineralized water were added and homogenization was carried out for 5 minutes. 180 g demineralized water were added and homogenization was carried out for 5 minutes. 197.4 g demineralized water were added and homogenization was carried out for 5 minutes. 197.4 g demineralized water were added and homogenize for 3 minutes. 228.5 g demineralized water were added and homogenization was carried out for 3 minutes.

Compositions 2’ and 3 were each applied to locks of hair, in a proportion of 0.4 g per gram of lock. The locks were then rinsed with water and dried under a hood (60°C).
The color of each lock was then evaluated in the CIE system, using a Minolta Spectrophotometer CM2600D colorimeter.
In this system, the three parameters respectively
denote the intensity of the color (L*), the green/red color axis (a*) and the blue/yellow color axis (b*).
The variation in the coloration of the locks before and after dyeing (i.e. application of the tested composition) is measured by (AEab*) which corresponds to the color uptake according to the following equation:

In this equation, represent the values measured
after dyeing with composition 2’ (comparative) or 3 (invention) and
represent the values measured before dyeing, corresponding to an untreated control lock (50% grey hair).

The greater the AEab* value, the greater the difference in color of the lock before and after dyeing, which shows good colour uptake. The results are indicated in the table 4 below.
