Detergent cosmetic compositions and use thereof

Abstract

Detergent and conditioning compositions having a washing base and a conditioning system with an oil nanoemulsion.

Description

The present invention relates to new cosmetic compositions with improved properties intended simultaneously for cleaning and for conditioning keratinous substances, such as hair, and comprising, in a cosmetically acceptable aqueous vehicle, a washing base composed of surface-active agents with a detergent power in which is also present, as conditioning agent, a nanoemulsion defined below. The invention also relates to the use of the said compositions in the abovementioned cosmetic application.

Detergent compositions (such as shampoos) based essentially on conventional surface-active agents of, in particular, anionic, non-ionic and/or amphoteric type, but more particularly of anionic type, are commonly used for cleaning and/or washing keratinous substances, such as hair. These compositions are applied to wet hair and the foam generated by massaging or rubbing with the hands makes it possible, after rinsing with water, to remove the various types of dirt initially present on the hair.

These base compositions certainly have a good washing power but the intrinsic cosmetic properties which are attached to them remain fairly weak, however, in particular because of the fact that the relatively aggressive nature of such a cleaning treatment can, in the long term, result in more or less marked damage to the hair fibre, in particular with the gradual removal of the lipids or proteins held in or at the surface of the hair fibre.

Consequently, in order to improve the cosmetic properties of the above detergent compositions, and more particularly of those which are called upon to be applied to sensitized hair (i.e. hair which is found to be damaged or embrittled, in particular under the chemical action of atmospheric agents and/or of hair treatments, such as permanent waves, dyings or bleachings), it is now usual to introduce into the latter additional cosmetic agents, known as conditioning agents, intended mainly to repair or limit the harmful or undesirable effects induced by the various treatments or attacks to which the hair fibres are more or less repeatedly subjected. These conditioning agents can, of course, also improve the cosmetic behaviour of natural hair.

It has already been proposed to use vegetable or animal oils for this purpose. On account of the insoluble nature of the oils which can be used in washing and conditioning compositions, the aim is to maintain the oils as an even dispersion in the medium without, however, causing a fall in the viscosity and a decline in the detergent and foaming properties of the compositions. The oils must also be carried to the keratinous substances treated with a view to conferring on them, depending on the application, properties of softness, of gloss and of disentangling, without conferring a greasy nature.

Thus, following considerable research carried out on the question, it has now been found by the Applicant Company that, while using (A) a washing base and (B) a conditioning system comprising at least one oil-in-water emulsion having oil globules with a mean size of less than 150 nm and comprising an amphiphilic lipid phase which comprises at least one non-ionic amphiphilic lipid which is liquid at an ambient temperature of less than 45° C., it is possible to obtain stable detergent compositions exhibiting excellent cosmetic properties, in particular the ease of styling, the form retention, the liveliness and the body of the treated hair, while retaining their good intrinsic washing power and in particular their foaming power.

These new compositions make it possible to deposit a larger amount of oil on hair than with a conventional emulsion but without a greasy feel or visual appearance.

The compositions in accordance with the invention confer on hair, after rinsing, a notable treating effect which is displayed in particular by an ease of disentangling and a contribution of body, lightness, sleekness, softness and suppleness, without any feeling of greasiness.

Thus, the subject of the present invention is new detergent and conditioning compositions, characterized in that they comprise, in a cosmetically acceptable aqueous medium, (A) a washing base and (B) a conditioning system comprising at least one oil-in-water emulsion having oil globules with a mean size of less than 150 nm and comprising an amphiphilic lipid phase, this amphiphilic lipid phase comprising at least one non-ionic amphiphilic lipid which is liquid at an ambient temperature of less than 45° C.

Another subject of the invention is the use in cosmetics of the above compositions for cleaning and/or removing make-up from and/or conditioning keratinous substances, such as hair and skin.

As indicated above, the essential components forming part of the composition of the products according to the invention are (A) a washing base and (B) a conditioning system comprising at least one oil-in-water emulsion having oil globules with a mean size of less than 150 nm and comprising an amphiphilic lipid phase, characterized in that the amphiphilic lipid phase comprises at least one non-ionic amphiphilic lipid which is liquid at an ambient temperature of less than 45° C.

A—WASHING BASE:

The compositions in accordance with the invention necessarily comprise a washing base, generally an aqueous washing base.

The surfactant or surfactants forming the washing base can be chosen without distinction, alone or as mixtures, from anionic, amphoteric, non-ionic and cationic surfactants.

However, according to the invention, the washing base preferably comprises anionic surfactants or mixtures of anionic surfactants and of amphoteric surfactants and, more preferentially still, contains only this type of surfactant or mixture of surfactants.

The minimum amount of washing base is that just sufficient to confer a satisfactory foaming and/or detergent power on the final composition, whereas excessively large amounts of washing base do not really contribute additional advantages.

Thus, according to the invention, the washing base can represent from 4% to 50% by weight, preferably from 10% to 35% by weight and more preferentially still from 12% to 25% by weight of the total weight of the final composition.

The surfactants which are suitable for implementing the present invention are in particular the following:

(i) Anionic surfactant(s):

Their nature does not assume a really critical character within the context of the present invention.

Thus, by way of example of anionic surfactants that can be used, alone or as mixtures, in the context of the present invention, there may be mentioned in particular (nonlimiting list) the salts (in particular alkali metal, especially sodium, salts, ammonium salts, amine salts, aminoalcohol salts or magnesium salts) of the following compounds: alkyl sulphates, alkyl ether sulphates, alkylamido ether sulphates, alkylarylpolyether sulphates, monoglyceride sulphates; alkylsulphonates, alkyl phosphates, alkylamidesulphonates, alkylarylsulphonates, α-olefinsulphonates, paraffinsulphonates; alkyl sulphosuccinates, alkyl ether sulphosuccinates, alkylamidesulphosuccinates; alkyl sulphosuccinamates; alkyl sulphoacetates; alkyl ether phosphates; acylsarcosinates; acylisethionates and N-acyltaurates, the alkyl or acyl radical of all these different compounds preferably containing from 12 to 20 carbon atoms, and the aryl radical preferably denoting a phenyl or benzyl group. Among the anionic surfactants which are further usable, there may also be mentioned the salts of fatty acids such as the salts of oleic, ricinoleic, palmitic and stearic acids, the acids of copra oil or of hydrogenated copra oil, and acyllactylates in which the acyl radical contains 8 to 20 carbon atoms. It is also possible to use weakly anionic surfactants, like alkyl-D-galactosideuronic acids and salts thereof, as well as the polyoxyalkylenated (C 6 -C 24 )alkyl ether carboxylic acids, the polyoxyalkylenated (C 6 -C 24 )alkylaryl ether carboxylic acids, the polyoxyalkylenated (C 6 -C 24 )alkylamido ether carboxylic acids and salts thereof, in particular those containing from 2 to 50 ethylene oxide groups, and mixtures thereof.

Among the anionic surfactants, it is preferable to use, according to the invention, alkyl sulphate and alkyl ether sulphate salts and mixtures thereof.

(ii) Non-ionic surfactant(s):

The non-ionic surface-active agents themselves are also compounds which are well known per se (in this respect see in particular the “Handbook of Surfactants” by M. R. Porter, published by Blackie & Son (Glasgow and London), 1991, pp. 116-178) and, in the context of the present invention, their nature does not assume any critical character. They can thus be chosen especially from (nonlimiting list) polyethoxylated, polypropoxylated or polyglycerolated fatty alcohols, alpha-diols, alkylphenols or acids, which have a fatty chain containing, for example, 8 to 18 carbon atoms, it being possible for the number of ethylene oxide or propylene oxide groups to range especially from 2 to 50 and it being possible for the number of glycerol groups to range especially from 2 to 30. Mention may also be made of the copolymers of ethylene and propylene oxide, the condensates of ethylene and propylene oxide with fatty alcohols; the polyethoxylated fatty amides preferably having from 2 to 30 mol of ethylene oxide, the polyglycerolated fatty amides on average containing 1 to 5 glycerol groups and in particular 1.5 to 4; the polyethoxylated fatty amines preferably having 2 to 30 mol of ethylene oxide; the oxyethylenated esters of sorbitan fatty acids having from 2 to 30 mol of ethylene oxide; the sucrose esters of fatty acids, the polyethylene glycol esters of fatty acids, alkylpolyglycosides, the N-alkylglucamine derivatives, amine oxides such as the oxides of (C 10 -C 14 )alkylamines or the N-acylaminopropylmorpholine oxides. It will be noted that alkylpolyglycosides constitute non-ionic surfactants which enter particularly well into the scope of the present invention.

(iii) Amphoteric surfactant(s):

The amphoteric surface-active agents, the nature of which does not assume any critical character in the context of the present invention, may be especially (nonlimiting list) derivatives of aliphatic secondary or tertiary amines in which the aliphatic radical is a linear or branched chain containing 8 to 22 carbon atoms and containing at least one water-solubilizing anionic group (for example carboxylate, sulphonate, sulphate, phosphate or phosphonate); (C 8 -C 20 )alkylbetaines, sulphobetaines, (C 8 -C 20 )alkylamido(C 1 -C 6 )alkylbetaines or (C8-C 20 )alkylamido(C 1 -C 6 )alkylsulphobetaines may further be mentioned.

The compositions in accordance with the invention can also contain up to 5% of pearlescent or opacifying agents well known in the state of the art, such as, for example, sodium or magnesium palmitates, sodium or magnesium stearates and hydroxystearates, or acylated derivatives containing a fatty chain, such as ethylene glycol or polyethylene glycol monostearates or distearates.

The compositions in accordance with the invention can in addition optionally contain other agents having the effect of improving the cosmetic properties of hair or of the skin without, however, detrimentally affecting the stability of the compositions. Mention may be made, in this respect, of cationic surface-active agents, anionic or non-ionic or cationic or amphoteric polymers, proteins, protein hydrolysates, ceramides, pseudoceramides, fatty acids containing linear or branched Cl 6 -C 40 chains, such as 18-methyleicosanoic acid, hydroxy acids, vitamins, panthenol, volatile or non-volatile silicones, which are soluble and insoluble in the medium, and mixtures thereof.

The conditioning agents of cationic polymer type which can be used in accordance with the present invention can be chosen from all those already known per se as improving the cosmetic properties of hair treated with detergent compositions, namely, in particular, those described in Patent Application EP-A-0,337,354 and in French Patent Applications FR-A-2,270,846, 2,383,660, 2,598,611, 2,470,596 and 2,519,863.

In a still more general way, within the meaning of the present invention, the expression “cationic polymer” denotes any polymer containing cationic groups and/or groups which can be ionized to cationic groups.

Among all the cationic polymers capable of being used in the context of the present invention, preference is given to the employment of quaternary derivatives of cellulose ether, such as the products sold under the name “JR 400” by the company Union Carbide Corporation, cyclopolymers, in particular diallyldimethylammonium salt homopolymers and copolymers of diallyldimethylammonium salt and of acrylamide, in particular the chlorides, sold under the names “Merquat 100”, “Merquat 550” and “Merquat S” by the company Merck, or cationic polysaccharides and more particularly guar gums modified by 2,3-epoxypropyltrimethylammonium chloride, sold, for example, under the name “Jaguar C13S” by the company Meyhall.

According to the invention, the cationic polymer or polymers can represent from 0.001% to 10% by weight, preferably from 0.005% to 5% by weight and, more preferentially still, from 0.01% to 3% by weight of the total weight of the final composition.

The compositions according to the invention can also contain foam synergists, such as C 10 -C 18 1,2-alkanediols or fatty alkanolamides derived from mono- or from diethanolamine.

Of course, a person skilled in the art will take care to choose this or these possible additional compounds and/or their amounts so that the advantageous properties intrinsically attached to the combination (washing base + oil nanoemulsion) in accordance with the invention are not, or not substantially, detrimentally affected by the envisaged addition or additions.

These compositions can be provided in the form of more or less thickened liquids, of creams or of gels and they are mainly suitable for washing or caring for the hair.

When the compositions in accordance with the invention are employed as conventional shampoos, they are simply applied to wet hair and the foam generated by massaging or rubbing with the hands is then removed, after an optional period of rest, by rinsing with water, it being possible for the operation to be repeated one or more times.

Another subject of the invention is a process for washing and for conditioning keratinous substances, such as, in particular, hair, which consists in applying, to the said wetted substances, an effective amount of a composition as defined above and in then rinsing with water, after an optional period of rest.

The compositions according to the invention are preferably used as shampoos for washing and conditioning the hair and they are applied, in that case, to wet hair in amounts which are effective for washing them, this application being followed by rinsing with water.

The compositions in accordance with the invention can also be used as shower gels for washing and conditioning the hair and/or the skin, in which case they are applied to the wet skin and/or hair and are rinsed after application.

Concrete but in no way limiting examples illustrating the invention will now be given.

(**) Emulsion

The emulsion contains the same compounds as the nanoemulsion but the preparation is carried out according to a conventional procedure. The size of the oil globules is approximately 1500 nm.

The shampoo compositions are prepared by mixing the emulsion or the nanoemulsion with the other constituents of the shampoo at room temperature.

The composition B is unstable and the oil separates out at the surface of the liquid, whereas the composition A is homogeneous and stable.

The composition B exhibits an insufficient foaming power, whereas the composition A according to the invention exhibits an excellent foaming power.

Shampooing was carried out by applying approximately 12 g of the composition A to sensitive hair which had been wetted beforehand. The shampoo is made to foam and then copious rinsing is carried out with water. The same procedure is carried out as above with the comparative composition B.

A panel of experts evaluated the appearance of the dried hair.

All the experts indicate that hair treated with the composition A according to the invention is highly individualized and non-sticky, whereas hair treated with the composition B has a dirty and greasy appearance.
