Description

TRANSPARENT COSMETIC COMPOSITION COMPRISING A CATIONIC SURFACTANT, A CATIONIC POLYMER, A NON-IONIC POLYSACCHARIDE, A POLYOXYALKYLENE FATTY ALCOHOL AND A POLYOL ESTER

The present invention relates to a transparent cosmetic composition, in particular hair composition, comprising at least one cationic surfactant, at least one cationic polymer, at least one non-ionic polysaccharide, at least one polyoxyalkylenated fatty alcohol and at least one polyol ester.

The invention also relates to a method for cosmetic treatment, in particular conditioning, of keratin fibers, in particular human keratin fibers such as hair, comprising at least one step of application to said fibers of the transparent cosmetic composition according to the invention.

The invention further relates to the use of said transparent cosmetic composition for the cosmetic treatment, preferably the conditioning, of keratin fibers, in particular human keratin fibers such as hair.

Natural hair or hair that has been treated with various chemical treatments can be dull, lacking care, damaged and weakened by the action of external atmospheric agents such as light and bad weather, as well as by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perming and/or straightening and repeated washing.

The hair thus finds itself lacking care for natural hair or damaged by these different factors and can in the long run become dry, rough, brittle, dull, split and/or limp.

Thus, to remedy these drawbacks, it is usual, or uncommon for natural hair, to use hair care products that use compositions intended to condition the hair in a suitable manner by providing it with satisfactory cosmetic properties, in particular smoothing, shine, softness to the touch (a natural feel, the hair is no longer rough), flexibility, lightness, good detangling properties making it easy to comb, and good discipline of the hair which thus has good styling.

These hair care compositions can be, for example, conditioning shampoos, conditioners, masks, serums.

However, these hair care compositions do not always give complete satisfaction in terms of visual aesthetics, soft and natural feel and/or ease of grip to take the right dose and apply it to the hair without dripping.

There is therefore a need to provide a clear or semi-clear composition which can be packaged in a pot, is easy to take, is easy to apply to damp hair and provides keratin fibres with cosmetic properties such as softness to the touch, smoothing, ease of detangling, good discipline, suppleness, lightness, shine and a clean sheath.

The applicant thus surprisingly discovered that the combination of at least one cationic surfactant, at least one cationic polymer, at least one non-ionic polysaccharide, at least one polyoxyalkylenated fatty alcohol and at least one polyol ester made it possible to meet these needs.

Thus, the subject of the present invention is a transparent cosmetic composition comprising:
(a) one or more cationic surfactants,
(b) one or more cationic polymers,
(c) one or more non-ionic polysaccharides,
(d) one or more polyoxyalkylenated fatty alcohols, and
(e) one or more polyol esters.

By "transparent composition" is meant a composition having a turbidity less than or equal to 200 NTU, NTU being the nephelometric units of measurement of turbidity.

Turbidity can be measured, for example, with a Model 2100P turbidimeter marketed by the Hach Company, the tubes used for the measurement being referenced AR698A cat 24347-06.

The calibration is carried out with formazine and the measurements are carried out at room temperature (20 to 25 °C). The compositions of the invention preferably have a turbidity less than or equal to 150 NTU, preferably less than or equal to 100 NTU. More preferably, the compositions of the invention have a turbidity ranging from 0.05 to 100 NTU, better still from 1 to 95 NTU, better still from 10 to 95 NTU, and even more preferably from 50 to 90 NTU.

The composition according to the invention preferably has a viscosity ranging from 1000 to 5000 mPa.s, preferentially from 1400 to 4000 mPa.s, better still from 1600 to 3500 mPa.s, and better still from 1800 to 3000 mPa.s.

Viscosity can be measured using a rheometer such as a Rheomat 180 (Mettler) equipped with a spindle 3 (200 rpm, 25°C, measurement at 30 s).

In addition, the composition according to the invention provides conditioning to keratin fibers such as hair, in particular softness to the touch, smoothing, ease of detangling, good discipline, suppleness, lightness, shine and sheathing.

The invention also relates to a process for the cosmetic treatment, in particular conditioning, of keratin fibers, in particular human keratin fibers such as hair, comprising at least one step of applying to said fibers the cosmetic composition according to the invention.

Another object of the invention is the use of the cosmetic composition according to the invention for conditioning keratin fibers, in particular human keratin fibers such as hair.

Non-ionic polysaccharide(s) (c)
The composition according to the invention may further comprise one or more non-ionic polysaccharides.

According to the invention, polysaccharides are also called sugar-motif polymers.

For the purposes of the present invention, the term “sugar unit” means an oxygenated hydrocarbon compound which has several alcohol functions, with or without aldehyde or ketone function, and which comprises at least 4 carbon atoms.

The sugar units can be optionally modified by substitution, and/or by oxidation and/or by dehydration.

The sugar units of nonionic polysaccharides are preferably derived from the following sugars: glucose; galactose; arabinose; rhamnose; mannose; xylose; fucose; anhydrogalactose; and fructose.

Preferably, the non-ionic polysaccharide(s) usable in the composition according to the invention are chosen from non-associative non-ionic polysaccharides, associative non-ionic polysaccharides, and mixtures thereof.

Examples of non-associative non-ionic polysaccharides include native gums such as:
(a) exudates from trees or shrubs;

These polysaccharides can be modified physically or chemically. Physical treatment includes, in particular, temperature.

Chemical treatments include esterification, etherification, amidation and oxidation reactions. These treatments also make it possible to obtain non-ionic polymers.

Preferably, these chemical or physical treatments are applied to guar gums, locust bean gums, starches and celluloses.

The non-ionic guar gums which can be used according to the invention can be modified by C ₁ to C ₆ (poly)hydroxyalkyl groups.

Among the _C1 to _C6 (poly)hydroxyalkyl groups, we can mention by way of example, the hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups.

These guar gums are well known in the state of the art and can for example be prepared by reacting corresponding alkene oxides such as for example propylene oxides with guar gum so as to obtain a guar gum modified by hydroxypropyl groups.

The hydroxyalkylation rate preferably varies from 0.4 to 1.2 and corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxyl functions present on the guar gum.

Such non-ionic guar gums, optionally modified by hydroxyalkyl groups, are for example sold under the trade names JAGUAR HP8, JAGUAR HP60 and JAGUAR HP120 by the company RHODIA CHIMIE.

Starch molecules can be derived from any plant source of starch, such as corn, potato, oat, rice, tapioca, sorghum, barley, peas or wheat. Hydrolysates of the starches mentioned above can also be used. The starch is preferably derived from potato.

Starches can be modified chemically or physically: in particular by one or more of the following reactions: pregelatinization, oxidation, crosslinking, esterification, etherification, amidation, heat treatments.

The non-associative non-ionic polysaccharides of the invention may be cellulosic polymers not comprising a _C10 to _C30 fatty chain in their structure.

According to the invention, the term “cellulosic” polymer means any polysaccharide compound having in its structure chains of glucose residues united by β-1,4 bonds; in addition to unsubstituted celluloses, cellulose derivatives may be anionic, cationic, amphoteric or non-ionic.

Thus, the cellulose polymers which can be used according to the invention can be chosen from unsubstituted celluloses including in microcrystalline form and cellulose ethers.

Among these cellulose polymers, we distinguish cellulose ethers, cellulose esters and cellulose ether esters.

Cellulose esters include inorganic cellulose esters (nitrates, sulfates or phosphates of cellulose, etc.), organic cellulose esters (monoacetates, triacetates, amidopropionates, acetatebutyrates, acetatepropionates or acetatetrimellitates of cellulose, etc.) and mixed organic/inorganic cellulose esters such as cellulose acetatebutyrate sulfates and acetatepropionate sulfates. Cellulose ether esters include hydroxypropylmethylcellulose phthalates and ethylcellulose sulfates.

Among the non-ionic cellulose ethers without a fatty chain in C ₈ to C ₃₀ ie "non-associative", we can cite the (C ₁ -C ₄ )alkylcelluloses such as methylcelluloses and ethylcelluloses (for example Ethocel standard 100 Premium from DOW CHEMICAL); the (poly)hydroxy(C ₁ -C ₄ )alkylcelluloses such as hydroxymethylcelluloses, hydroxyethylcelluloses (for example Natrosol 250 HHR proposed by AQUALON) and hydroxypropylcelluloses (for example Klucel EF from AQUALON); mixed celluloses (poly)hydroxy(C ₁ -C ₄ )alkyl-(C ₁ -C ₄ )alkylcelluloses such as hydroxypropyl-methylcelluloses (e.g. Methocel E4M from DOW CHEMICAL), hydroxyethyl-methylcelluloses, hydroxyethyl-ethylcelluloses (e.g. Bermocoll E 481 FQ from AKZO NOBEL) and hydroxybutyl-methylcelluloses.

The non-associative non-ionic polysaccharide(s) may advantageously be chosen from non-ionic cellulose ethers without a fatty chain in _C8 to _C30 and their mixtures, more preferably from hydroxyethylcelluloses and their mixtures.

As non-ionic polysaccharides which can be used in the invention, mention may also be made of associative non-ionic polysaccharides.

It is recalled that “associative polymers” are polymers capable, in an aqueous medium, of reversibly associating with each other or with other molecules.

Their chemical structure more particularly comprises at least one hydrophilic zone and at least one hydrophobic zone.

By “hydrophobic group” is meant a radical or polymer with a hydrocarbon chain, saturated or not, linear or branched, comprising at least 8 carbon atoms, preferably from 10 to 30 carbon atoms, in particular from 12 to 30 carbon atoms and more preferably from 18 to 30 carbon atoms.

The pH of the composition is 5.2.

A transparent composition was obtained with a turbidity of 79.7 NTU, measured using a Model 2100P turbidimeter marketed by HACH Company, the tubes used for the measurement being referenced AR698A cat 24347-06.

This composition has a viscosity of 2580 mPa.s at 25 °C (30 s) measured using a Rheomat 180 (Mettler) equipped with a spindle 3 (200 rpm).

Composition A was characterized using an Anton-Paar® MCR-502 rotational rheometer, equipped with an air Peltier element to regulate the temperature. A cone/plate geometry ∅ 50 mm / 1° (5 μm sandblasted steel) was used as well as an anti-evaporation device to avoid evaporation phenomena during the measurement. The temperature was set at 25°C. The protocols used are as follows:
- Amplitude scanning: for the determination of the Linear Visco-Elasticity Domain (LVED) and the threshold stress in oscillation. The measurements are made at a constant frequency of 1 Hz between 0.01 and 500% of deformation. 6 points per decade are acquired (29 points in total) distributed on a logarithmic scale of the deformation. The values of d, G', G'' and G* were recorded at 1% of deformation.
- Flow curve: Shear rate scan, between 0.01 to 1000 s ^-1 , on 26 points, in steady state.

The values of G’ and G" at 1% deformation obtained for composition A are respectively 86 and 58 Pa.

Applied to the hair after shampooing, it provides good cosmetic properties in terms of fluidity, softness and shine. The hair is more hydrated and stronger.
