ABSTRACT:
The present invention relates to novel cosmetic compositions with improved properties, intended both for cleaning, conditioning and styling the hair, and comprising, in a cosmetically acceptable vehicle, a washing base consisting of surfactants with detergent power, in which cationic polymers in combination with specific silicones are also present as conditioners. The invention also relates to the use of the said compositions in the abovementioned cosmetic application.
It is common to use detergent hair compositions (or shampoos) based essentially on standard surfactants of anionic, nonionic and/or amphoteric type in particular, but more particularly of anionic type, to clean and/or wash the hair. These compositions are applied to wet hair and the lather generated by massaging or rubbing with the hands removes, after rinsing with water, the various types of soiling which are initially present on the hair.
Admittedly these base compositions are of 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 intended 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 being 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. These conditioners may, of course, also improve the cosmetic behaviour of natural hair.
The conditioners most commonly used to date in shampoos are cationic polymers, 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.
Moreover, it has for some time been sought to obtain conditioning shampoos which are capable of giving washed hair not only the cosmetic properties mentioned above but also, to a greater or lesser extent, styling, volume, shaping and hold properties. These washing shampoos with improved general cosmetic properties are often referred to for simplicity as “styling shampoos”, and this expression will be adopted in the description hereinbelow.
However, despite the progress made recently in the field of styling shampoos based on cationic polymers, these shampoos are not really completely satisfactory, and as such a strong need still exists currently as regards being able to provide novel products which give better performance with respect to one or more of the cosmetic properties mentioned above.
The present invention is directed towards satisfying such a need.
Thus, after considerable research conducted in this matter, the Applicant has now found, entirely surprisingly and unexpectedly, that by using (A) a washing base and (B) a conditioning system comprising at least one cationic polymer and at least one mixture of suitably selected specific silicones, as defined below, it is possible to obtain detergent compositions which give excellent cosmetic properties, in particular ease of styling, hold, liveliness and volume to the hair treated, while at the same time retaining their good intrinsic washing power.
All of these discoveries form the basis of the present invention.
Thus, according to the present invention, novel detergent and conditioning hair compositions are now proposed, 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 grafted silicone polymer comprising a polysiloxane portion and a portion consisting of a non-silicone organic chain, one of the two portions constituting the main chain of the polymer, the other being grafted onto the said main chain, and at least one aminosilicone.
A subject of the invention is also the cosmetic use of the above compositions for cleaning, conditioning and/or styling the hair.
However, other characteristics, aspects and advantages of the invention will emerge even more clearly on reading the description which follows, as well as the concrete, but in no way limiting, examples intended to illustrate it.
As indicated above, the essential constituents forming part of the composition of the hair products of the invention are (A) a washing base, (B) a conditioning system comprising (i) the cationic polymer(s), and (ii) a mixture of at least one grafted silicone polymer and at least one aminosilicone.
A—WASHING BASE
The compositions in accordance with the invention necessarily comprise a washing base, which is generally aqueous.
The surfactant(s) forming the washing base can be chosen, indifferently, alone or as mixtures, from anionic, amphoteric, nonionic, zwitterionic and cationic surfactants.
The minimum amount of washing base is that which is just sufficient to give the final composition a satisfactory foaming and/or detergent power, and excessive amounts of washing base will not really give 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 even more preferably from 12% to 25% by weight, of the total weight of the final composition.
The surfactants which are suitable for carrying out the present invention are in particular the following:
(i) Anionic Surfactant(s):
In the context of the present invention, their nature is not a truly critical feature.
Thus, as examples of anionic surfactants which can be used, alone or as mixtures, in the context of the present invention, mention may be made in particular (non-limiting list) of salts (in particular alkaline salts, especially sodium salts, ammonium salts, amine salts, amino alcohol salts or magnesium salts) of the following compounds: alkyl sulphates, alkyl ether sulphates, alkylamidoether sulphates, alkylarylpolyether sulphates, monoglyceride sulphates; alkyl sulphonates, alkyl phosphates, alkylamide sulphonates, alkylaryl sulphonates, &agr;-olefin sulphonates, paraffin sulphonates; alkyl sulphosuccinates, alkyl ether sulphosuccinates, alkylamide sulphosuccinates; alkyl sulphosuccinamates; alkyl sulphoacetates; alkyl ether phosphates; acyl sarcosinates; acyl isethionates and N-acyltaurates, the alkyl or acyl radical of all of these various 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 can also be used, mention may also be made of fatty acid salts such as the salts of oleic, ricinoleic, palmitic and stearic acids, coconut oil acid or hydrogenated coconut oil acid; acyl lactylates in which the acyl radical contains 8 to 20 carbon atoms. Use may also be made of weakly anionic surfactants, such as alkyl-D-galactosiduronic acids and their salts, as well as polyoxyalkylenated carboxylic ether acids and their salts, in particular those containing from 2 to 50 ethylene oxide groups, and mixtures thereof. Anionic surfactants of the polyoxyalkylenated carboxylic ether acid or salt type are, in particular, those which correspond to formula (1) below:

—(OC

H

n
—OCH

COOA (1)
in which:
R
1
denotes an alkyl or alkaryl group, and n is an integer or decimal (average value) which can range from 2 to 24 and preferably from 3 to 10, the alkyl radical having between 6 and 20 carbon atoms approximately, and aryl preferably denoting phenyl.
A denotes H, ammonium, Na, K
