  AQUEOUS COMPOSITION FOR HAIR CARE.

  The present invention relates to compositions particularly useful for the care of the hair and relates to methods of hair care

  using such compositions.

  It is known from the state of the art of hair treatment methods by certain compounds based on quaternary amines for the care of the hair, that is to say to facilitate their combing, to make them more docile, to make their touch softer and make them glossy, etc. Although such known compositions have proven to be effective to some extent, one of their major drawbacks lies in the fact that

  that their effects are not long-lasting, that is, they can not

  do not try repeated shampoos.

  It has been found that it is possible to improve sham stability.

  additions of certain classes of silicone polymers.

  Examples of such polymers are "Amodimethicone" having the following structure: CH3 I

HO - Si -O-

  In which: x and y are integers dependent on the molecular weight, the average molecular weight being approximately between 5,000 and 5,000.

and 10,000.

  However, even the use of such silicone polymers is not entirely satisfactory. The investigations which led to the present invention make it possible to observe that the effectiveness of the treatment, as well as the duration of the effects conferred by these silicone polymers, can be greatly improved by incorporating into the treatment composition or care of one or more cationic polymers. Cationic polymers that can be used in the context of

  of the present invention belong to different classes.

  Three classes of polymers have indeed proved particularly useful, that is to say the polymers that are sold under the trade name MERQUAT (MERQUAT 100 and MERQUAT 550), ONAMER (ONAMER M),

  as well as the quaternized polyvinylpyridines.

  MERQUAT 100 is a dimethyldiallyl ammonium chloride polymer; it is likely formed mixtures of compounds having the following formulas:

in which:

  These compounds vary in molecular weight, however, in general, poly-

  mothers of this class who may be employed in the context of the invention

  have a molecular weight of between 4000 and 550 000 and, more

  particularly, between 20,000 and about 100,000.

  MERQUAT 550 is a copolymer of dimethyldiallyl ammonium chloride and acrylamide; it probably presents the following formula:

  the indices n and m being integers which depend on the molecular weight.

  ONAMER-type polymers that can be advantageously used

  in the context of the present invention are poly (dimethyl chloride

  butenyl ammonium) -e, w-bis (triethanol ammonium chloride) may be represented by the following formula:

OHCH2CH2 CH3 1 / CH2CH20H

  OHCH2CH2 -N N-N + CH2-CH = CH-CH2 -N + -CH2CH2OH

OHCH2CH2 CH3 CL- CH2CH20H

Cl- n Cl-

in which:

  n is an integer dependent on the molecular weight.

  The molecular weights of these ONAMER type polymers, likely to be

  employed in the context of the present invention, may differ.

  In most cases, however, they must be included between approximately

  800 and 5000 and preferably between about 1000 and 3000.

  A third variety of polymeric materials that can be used

  are the polymers and copolymers of quaternized polyvinylpyridine.

  These have the following general formulas:

-CH2 CH-

N + I R

--- CH2 CH

or

CH-CH2

n m _n A

24,536 12

  in which: R is an alkyl radical comprising 1 to 20 carbon atoms, X- is an anion, such as a halide, sulfate or carboxylate, and

  n is an integer dependent on the molecular weight.

  These compounds may have a molecular weight of between 5,000 and

about 100,000.

  As an example of a cationic polymer of this group, mention may be made of the following compound:

-CH2 CH

NOT-

CH3

  n consisting of polyvinyl methyl pyridinium iodide, having an average molecular weight of 50,000, wherein

  n is an integer dependent on the molecular weight.

  The amount of cationic polymer contained in the compositions or formulations according to the present invention depends on the particular results to be achieved. In general, this amount should form a proportion-of the order of about 0.01 to 10% by weight, expressed relative to

  the total weight of the aqueous composition, the maximum values being

  taken between about 0.05 and 3% expressed in relation to this total weight.

  The amount of silicone polymer that is incorporated into the composition

  hair care according to the present invention may vary.

  In general, however, it is between about 0.2 and 10% by weight expressed relative to the total weight of the composition, preferably between

about 1 and 4% by weight.

  Although the cationic polymers mentioned above and the silicone polymers constitute the essential active ingredients of the compositions

  according to the present invention, these compositions may also contain

  other ingredients which may, in particular, improve the properties

  organoleptic or facilitate the application.

  Thus, it is within the scope of the present invention, also, to incor-

  porer in the aforementioned compositions one or more materials such as thickeners, perfumes, opacifiers, etc.

  The support or vehicle associated with the compositions according to the present invention

  This is usually a vehicle or aqueous carrier. These compositions may take any form, namely, be in the form of solutions, aqueous emulsions, aqueous gels, etc. As used in the context of the present invention, the term "carrier or aqueous vehicle" implies all the cases where water is practically the only material which constitutes this vehicle, as well as those in which the water is associated relatively large proportions of other substances, such as solvents, thickeners, emulsifiers, gelling agents, etc. The compositions of the present invention may be applied to the hair in any convenient manner. A typical method involves the application of the care compositions as described in Example 1, hereinafter, to freshly shampooed hair, the treatment of the hair to penetrate the composition into the hair, and the maintenance of said hair. composition on the hair for 1 to 5 minutes, then the

  rinsing the hair with water before combing.

  The amount of care composition according to the present invention applied to the hair may vary but, in general, must not be less than 1% of the

  hair weight, and must not exceed 20% of that weight.

  Other advantages and features of the present invention are

than test support.

  Unbroken Caucasian hair strands are shampooed with "Herbal Essence" shampoo @, according to the directions on the Directions for Use. The ratio of the amount of the shampoo (by weight) to the weight of the hair and the amount of water used for rinsing after shampooing are kept similar to the conditions that are usually used. After rinsing, the care composition of the above-mentioned Example 1 is applied

  hair (O, lg of composition per gram of hair).

  The composition is then applied to the hair for 30 seconds, then left in contact with the hair for an additional minute, after which the hair is rinsed and combed. The determinations of combing are determined using the procedures described in the article by Garcia and Diaz (J. Soc Cosmetic Cheem, 27, 379, 1976). The test essentially involves the passage of the hair braid on a comb attached to a measuring device.

  the voltage which, in turn, is connected to a recording device.

  The work involved in the passage of the braid through the hair is read on the integrator connected to this recording system and constitutes to measure

  objectively the difficulty or ease of combing.

  After determining the combing properties of the hair after shampooing

  in the present invention, the locks undergo

  five successive shampoos and undergo a combing test again.

  The results of the combing facility tests are summarized in Table I, above. In this table, the "Maximum Combing Strength" is

  expressed in units of work (G) "Gram Force".

  More important are these values, the harder it is to comb the hair.

  It is found that a longer resistance to the treatment time is ob-

  when using the compositions of Example 4.

  Brown Caucasian hair, freshly shampooed, is also used.

  in the test, the results of which are given in Table II,

also above.

  Of course, the present invention is not limited to the examples

  and modes of implementation described above; it is likely to

  Many variants accessible to those skilled in the art, depending on the applications

  contemplated and without departing from the spirit of the invention.
