Abstract

Description

The present invention relates to new cosmetic compositions having improved properties, intended for simultaneously cleansing and conditioning the hair. The cosmetic composition comprises, in a cosmetically acceptable vehicle, a washing base comprising surfactants having detergent power, and as conditioning agents, cationic polymers in combination with particular silicones. The invention also relates to the use of these compositions in cosmetic applications such as, for simultaneously cleansing and conditioning the hair.

It is known in the art to use detergent hair-care compositions (or shampoos) based essentially on traditional surfactants, in particular of the anionic, nonionic and/or amphoteric type, and more especially of the anionic type for cleansing and washing the hair. These compositions are applied to wet hair, and the lather generated by massage or friction with the hands makes it possible, after rinsing with water, to remove the various kinds of soil initially present on the hair. These base compositions admittedly possess good washing power, but the intrinsic cosmetic properties which are associated with them remain, however, rather poor, in particular because the aggressive nature of such a cleansing treatment can lead eventually, on the hair fibre, to more or less pronounced damage, linked especially to the progressive removal of the lipids or proteins contained in or at the surface of the fibre.

Thus, in order to improve the cosmetic properties of the above detergent compositions, and more especially detergent compositions for application to sensitized hair (i.e., hair which is damaged or weakened, in particular through the chemical action of environmental agents and/or of hair treatments such as permanent-waving, dyeing or bleaching), it is known to introduce into these compositions supplementary cosmetic agents termed conditioning agents. The main purpose of these conditioning agents is to rectify or limit the harmful or undesirable effects induced by the various treatments or types of attack to which the hair fibres are more or less repeatedly subjected to and, of course, they can also improve the cosmetic behavior of natural hair.

The conditioning agents most commonly used to date in shampoos are cationic polymers, silicones and/or silicone derivatives which, in effect, impart to washed, dry or wet hair an ease of disentangling, softness and a smoothness which are markedly enhanced in comparison to what can be obtained with corresponding cleansing compositions which do not contain them. In addition, on sensitized hair, the use of a mixture of silicone and cationic polymer is preferred.

In spite of the progress recently made in the field of shampoos based on cationic polymers and silicone, they are not completely satisfactory. Thus, there is still at the present time a strong need for new products displaying improved performance with respect to one or more of the cosmetic properties mentioned above.

The present invention is directed towards meeting this need.

Thus, following a considerable amount of research conducted on this topic, the present inventors have, completely unexpectedly and surprisingly, discovered that, by using a combination of two particular and appropriately selected types of silicones, as defined below, in detergent hair-care compositions containing traditional cationic polymers as conditioning agents, it is possible to substantially and significantly improve the cosmetic properties associated with these compositions while preserving their good intrinsic washing power.

The compositions according to the invention impart to the hair, after rinsing, a noteworthy treatment effect which manifests itself, in particular, in an ease of disentangling as well as in providing volume, of bounce, smoothness, softness and suppleness.

All these discoveries underlie the present invention.

Thus, a subject of the present invention is new detergent and conditioning hair-care compositions comprising, in a cosmetically acceptable medium, (A) a washing base and (B) a conditioning system comprising at least one cationic polymer and a mixture of at least one aminated silicone and at least one insoluble silicone of viscosity less than or equal to 100 Pa.s (100,000 cSt).

Another subject of the invention is the use in cosmetics of the above compositions for cleansing and conditioning the hair.

However, other characteristics, aspects and advantages of the invention will become more apparent on reading the description which follows, as well as the specific, but in no way limiting, examples designed to illustrate it.

As stated above, the essential components of the hair-care products according to the invention are (A) a washing base and (B) a conditioning system comprising (i) the cationic polymer or polymers, (ii) the aminated silicone or silicones and (iii) the insoluble silicone or silicones of specific viscosity.

A--WASHING BASE:

The compositions according to the invention necessarily comprise a washing base, which is generally aqueous.

The surfactant or surfactants forming the washing base may be selected from anionic, amphoteric, nonionic and cationic surfactants and mixtures thereof.

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

The minimum amount of washing base is that which is just sufficient to impart a satisfactory lathering and/or detergent power to the final composition. Excessively large amounts of washing base do not really provide any 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 still more preferably from 12% to 25% by weight of the total weight of the final composition.

The surfactants suitable for carrying out the present invention are, in particular, the following:

(i) Anionic surfactant(s):

In the context of the present invention, the nature of the anionic surfactants is not of critical importance. Thus, according to the present invention, as examples of anionic surfactants which can be used, alone or in combination, mention may preferably be made (non-limiting list) of the salts (especially alkali metal salts, in particular sodium salts, ammonium salts, amine salts, salts of amino alcohols or magnesium salts) of the following compounds: alkyl sulphates, alkyl ether sulphates, alkylamido ether sulphates, alkylaryl polyether sulphates, monoglyceride sulphates; alkylsulphonates, alkyl phosphates, alkylamidesulphonates, alkylarylsulphonates, .alpha.-olefin sulphonates, paraffin sulphonates; alkylsulphosuccinates, alkyl ether sulphosuccinates, alkylamidesulphosuccinates; alkylsulphosuccinamates; alkylsulphoacetates; alkyl ether phosphates; acylsarcosinates; acylisethionates and N-acyltaurates; the alkyl or acyl radicals of all these different compounds preferably contain from 12 to 20 carbon atoms, and the aryl radical preferably denotes a phenyl or benzyl group. Among anionic surfactants which can also be used, mention may also be made of fatty acid salts such as the salts of oleic, ricinoleic, palmitic and stearic acids, and coconut oil or hydrogenated coconut oil acids; and acyllactylates in which the acyl radical contains 8 to 20 carbon atoms. It is also possible to use weakly anionic surfactants, such as alkyl D-galactosiduronic acids and their salts, as well as polyoxyalkylenated ether carboxylic acids and their salts, preferably those containing from 2 to 50 ethylene oxide groups, and mixtures thereof. The anionic surfactants of the type comprising polyoxyalkylenated ether carboxylic acids or salts are, in particular, those corresponding to formula (1):

R.sub.1 --(OC.sub.2 H.sub.4).sub.n --OCH.sub.2 COOA (1) wherein: R.sub.1 represents an alkyl or alkylaryl group and n is an integer or decimal number (average value) ranging from 2 to 24 and preferably from 3 to 10, the alkyl radical having from 6 to 20 carbon atoms approximately, and aryl preferably representing phenyl, A represents H, ammonium, Na, K, Li, Mg or a monoethanolamine or triethanolamine residue.

The detergent compositions according to the invention have a final pH generally ranging from 3 to 10. Preferably, the pH ranges from 5 to 8. Adjustment of the pH to the desired value may be done in the traditional manner by adding a base (organic or inorganic) to the composition, for example aqueous ammonia or a primary, secondary or tertiary (poly)amine such as monoethanolamine, diethanolamine, triethanolamine, isopropanolamine or 1,3-propanediamine, or alternatively by adding an acid, preferably a carboxylic acid such as, for example, citric acid.

The detergent compositions according to the invention may naturally contain, in addition, all the standard adjuvants encountered in the field of shampoos, such as, for example, perfumes, preservatives, sequestering agents, thickeners, emollients, foam modifiers, colorants, pearlescent agents, hydrating agents, antidandruff or antiseborrhoeic agents, vitamins, sunscreen agents, suspending agents and the like.

Naturally, a person skilled in the art will take care to choose this/these possible supplementary compound(s) and/or the amounts thereof in such a way that the advantageous properties intrinsically associated with the quaternary combination (washing base+cationic polymer+two specific silicones) according to the invention are not, or are not substantially, impaired by the addition or additions envisaged.

These compositions may take the form of more or less thickened liquids, of creams or of gel, and they are mainly suitable for washing the hair, for hair care and/or for hair styling. They may also take the form of lotions to be rinsed.

When the compositions according to the invention are employed as traditional shampoos, they are simply applied to wet hair, and the lather generated by massage or friction with the hands is then removed, after an optional period of exposure, by rinsing with water, it being possible for the operation to be repeated once or several times.

Another subject of the invention is a process for washing and conditioning keratinous fibres such as the hair, comprising the steps of applying to the fibres in the wet state an effective amount of a composition as defined above, and in then rinsing with water after an optional period of exposure.

As stated above, the compositions according to the invention impart to the hair, after rinsing, a noteworthy styling effect which manifests itself, in particular, in an ease of styling and of hold as well as in a provision of volume and of bounce which are markedly improved.

A specific but in no way limiting example illustrating the invention will now be given.
