Description

Cosmetic composition comprising amino acids, hydroxylated (poly)carboxylic acids and associative polymers, and cosmetic treatment method

The present invention relates to a cosmetic composition, in particular hair composition, comprising one or more amino acid type compounds, one or more hydroxy carboxylic acids, and one or more associative polymers. The invention also relates to a cosmetic treatment method using said composition.

Consumers around the world generally find themselves in contact with a wide variety of water sources which have an impact on hair, particularly on its cosmetic properties and/or the performance of hair products.

So-called mineral waters contain, for example, variable quantities of minerals present in the form of dissolved ions such as calcite (present in the form of calcium), dolomite (present in the form of calcium and magnesium), magnetite (present in the form of iron ) and chalcanthite (present in the form of copper). So-called hard water is also concentrated in minerals such as calcium and magnesium and swimming pool water is concentrated in copper salts from algaecides used in the treatment of swimming pools.

Hair has a strong tendency to absorb these minerals and/or their metallic salts because of the presence on their surface of anionic functions which correspond in particular to the sulfonic or carboxylic functions of keratin. Furthermore, the isoelectric point of the hair is generally described between 3.2 and 4. As a result, in everyday life, the pH of the water applied to the hair is greater than such values, which leads to a fiber negatively charged.

Minerals, often versatile cations, will therefore be attracted and captured by this negatively charged fiber by forming chemical bonds which prevent their release by conventional hair treatment processes. This results in a possible accumulation of minerals on the hair over time. Such fixation depends not only on the hardness of the water, the frequency and/or duration of exposure of the hair to the water in question but also on the nature and length of the hair (in particular porosity and load) as well as than their damaged state.

The accumulation of these minerals and/or their metallic salts can cause modifications to the hair fiber and, in particular, a more or less marked modification of the cosmetic properties of the hair. Thus an accumulation of calcium and magnesium can lead to dry hair, lacking shine, while an accumulation of copper can lead to greening of the hair.

In addition, the accumulation of metal salts (iron, copper, for example) can accelerate damage to hair because they catalyze redox reactions and generate HO° hydroxyl radicals that can be harmful to the keratin fiber, including low contents.

This can result in photo-degradation of the fiber, lightening of the fiber, as well as an alteration of the properties of the hair, which can lead to premature breakage of the hair; These phenomena are particularly observed during the subsequent use of lightening products or coloring products.

In other words, hair can become less resistant, more weakened, or even break more easily, or even lose its shine, due to the accumulation of minerals and/or their metallic salts.

There is therefore a real need to have compositions making it possible to combat the accumulation of metal ions, from minerals and metal salts dissolved in water, or even to allow them to be extracted from keratin fibers, in order to limit their negative impacts. and overcome all of the disadvantages mentioned above.

The composition which is the subject of the present invention, and its implementation, make it possible to achieve this goal.

The subject of the present invention is therefore a cosmetic composition, preferably hair composition, comprising:

- one or more compounds of the amino acid type, preferably present in a total content of at least 0.5% by weight, relative to the total weight of the composition,

- one or more hydroxylated (poly) carboxylic acids, comprising 2 to 8 carbon atoms, and/or their salts, preferably present in a total content of at least 0.5% by weight, relative to the total weight of the composition, and

- one or more associative polymers, preferably present in a total content of at least 0.5% by weight, relative to the total weight of the composition.

It has been found that the composition according to the invention makes it possible to improve the resistance to breakage of the hair, to strengthen the hair and also to significantly limit its reduction or loss of shine, undesirable effects likely to be caused by the presence of metal ions, in particular copper or calcium, within said fibers.

After application of the composition, the fibers are reinforced, said reinforcement being improved progressively with successive applications of the composition.

It has also been noted that the composition according to the invention also makes it possible to provide conditioning properties to the hair, in particular a smooth feel, softness, shine and easier detangling, while providing strength, of the body and a mass effect on the hair.

It finds a very particular application in cosmetic treatment, in particular the washing and/or conditioning, of sensitized, weakened and/or damaged keratin fibers, in particular following physical treatments (repeated brushing) and/or chemical treatments, for example coloring. , bleaching, perming and/or straightening.

It is particularly suitable for cosmetic treatment, in particular washing and/or conditioning, of keratin fibers loaded with metals, in particular calcium and/or copper, at contents of at least 100 ppm, better still at least 200 ppm; in particular loaded with copper, in particular at contents of at least 100 ppm, better still at least 200 ppm and/or loaded with calcium in particular at contents of at least 4,000 ppm, better still at least 10,000 ppm.

In what follows, and unless otherwise indicated, the limits of a domain of values are included in this domain, in particular in the expressions “between” and “ranging from… to…”.

A third compound used in the preparation of the polyurethane of formula (Ia) is a hydrophobic compound intended to form the terminal hydrophobic groups of the polymer of formula (Ia).

This compound consists of a hydrophobic group and a labile hydrogen function, for example a hydroxyl, primary or secondary amine, or thiol function.

For example, this compound may be a fatty alcohol, such as stearyl alcohol, dodecyl alcohol, decyl alcohol. When this compound comprises a polymer chain, it may for example be alpha-hydroxy hydrogenated polybutadiene.

The hydrophobic group of the polyurethane of formula (Ia) can also result from the quaternization reaction of the tertiary amine of the compound comprising at least one tertiary amine unit. Thus, the hydrophobic group is introduced by the quaternizing agent. This quaternizing agent is a compound of type RQ or R'Q, in which R and R' are as defined above and Q designates a leaving group such as a halide, a sulfate, etc.

The cationic associative polyurethane may further comprise a hydrophilic sequence. This sequence is provided by a fourth type of compound used in the preparation of the polymer.

The labile hydrogen functions are alcohol, primary or secondary amine, or thiol functions. This compound may be a polymer terminated at the ends of the chains by one of these labile hydrogen functions.

The hydrophilic group denoted Y in formula (Ia) is optional. Indeed, the units with quaternary or protonated amine function can be sufficient to provide the solubility or hydrodispersibility necessary for this type of polymer in an aqueous solution.

Although the presence of a hydrophilic Y group is optional, cationic associative polyurethanes comprising such a group are preferred.

The invention also relates to a process for cosmetic treatment, in particular hair treatment, in particular for washing and/or conditioning, keratin fibers, in particular hair, comprising the application to said fibers of a cosmetic composition according to invention, preferably followed by rinsing, after a possible exposure time.

Preferably, it is a hair treatment process, in particular washing and/or conditioning, sensitized, weakened and/or damaged hair, or hair loaded with metal ions, in particular copper and/or calcium. .

In particular, it may be a cosmetic treatment process for strengthening hair, particularly sensitized, weakened and/or damaged hair.

It can also be a process to limit the loss of shine of hair, particularly sensitized, weakened and/or damaged hair.

Said process may also comprise at least two successive stages of application, to the hair, in particular sensitized, weakened and/or damaged hair, of a composition as defined above; we then speak of a multi-application process.

The following examples serve to illustrate the invention without, however, being limiting in nature.

In the examples which follow, all quantities are indicated, unless otherwise indicated, as a mass percentage of active ingredient (g% MA) relative to the total weight of the composition.

Example 1

The following compositions A according to the invention and A' comparative were prepared from the ingredients indicated in the tables below (g% MA):

Composition HAS HAS' CITRIC ACID 1.5 1.5 GLYCINE 2.5 2.5 PEG-150/DECYL ALCOHOL/SMDI COPOLYMER 0.6 - AMODIMETHICONE 1.1 1.1 BEHENTRIMONIUM CHLORIDE 3 3 HYDROXYPROPYL GUAR 0.15 0.15 CETEARYL ALCOHOL 7 7 CETYL ESTERS 1.5 1.5 ISOPROPYL ALCOHOL 0.7 0.7 GLYCERIN 1 1 POLYQUATERNIUM-37 0.08 0.08 PROPYLENE GLYCOL 0.2 0.2 STEARETH-100 0.25 0.25 Conservatives Qs Qs Water Qsp 100% Qsp 100%

Composition A is in the form of a cream and can advantageously be used before shampooing as a pre-shampoo or after shampooing as a hair mask.

This composition can be used for detangling hair, providing care and strength (body and mass effect) and leads to an improved, homogeneous hair feel from root to tip (smooth feel).

The composition also exhibits reinforcing properties.

The smooth feel of the fiber is evaluated using the extensometry method.

The compositions were applied to strands of medium-bleached Caucasian hair, previously washed with shampoo and rinsed.

We then apply 0.4 g of composition per g of hair and rinse; the wicks are then dried in an oven (30 min, 60°C), then the measurement is carried out.

Principle of the method: the method consists of measuring the friction forces of a wick, during its movement (in the root/tip direction) at constant speed, between two pads gripping it at constant compression. This method makes it possible to evaluate “smoothness to the touch” by mimicking the passage of two fingers along a strand of hair.

The lower the forces required to move the strand along its length, the smoother the surface condition of the hair.

The following results are obtained (average over 3 strands):

Work (mJ) Standard deviation Composition A 55.48 8.68 Composition A’ 102.74 17.23

The lower the measured work, the better the performance of the evaluated formula in terms of smoothness.
