ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a composition, in particular one for making up the eyes, comprising oxyalkylenated silicone derivatives. These compositions have improved cosmetic properties, in particular of staying power.
2. Description of the Background
Many mascara formulations exist on the market. However, the consumer still expects an improvement in the properties of these mascaras, namely the lengthening of the eyelash, better adhesion of the composition to the eyelash, better shaping, also referred to as weighting, of the eyelashes, better staying power of the make-up over time and better resistance to mechanical stresses. For example, some users wish to be able to keep the same make-up on for the day and the evening. It is also known that rubbing the fingers on the eyelids and the contact of spectacles with the eyelashes tend to crumble the mascara away. In particular, the presence of pigments and/or fillers in compositions for making up the eyelashes makes these compositions particularly subject to crumbling. The compositions known to date have not solved these problems satisfactorily.
The object of the present invention is to provide a composition, in particular one for making up the eyes, which dries rapidly and has improved properties of lengthening and weighting of the eyelashes, of staying power and of mechanical strength.
SUMMARY OF THE INVENTION
The object of the invention is met by a cosmetic composition, in particular one for making up the eyelashes, comprising:
(a) at least one aqueous phase comprising at least one film-forming polymer,
(b) at least one fatty phase comprising at least one wax, and
(c) at least one silicone selected from the group consisting of:
(i) oxyalkylenated silicones, and
(ii) linear polysiloxane-polyoxyalkylene block copolymers
The object of the invention is also met by the use of a composition as defined above for the production of a make-up having better staying power over time and/or improved weighting and/or better resistance to crumbling and/or better lengthening of the eyelashes and/or an improved rate of drying.
The object of the invention is also met by the use of a silicone selected from the group consisting of:
(i) oxyalkylenated silicones, and
(ii) linear polysiloxane-polyoxyalkylene block copolymers,
in a cosmetic composition, in particular one for making up the eyes, comprising:
(a) at least one aqueous phase comprising al least one film-forming polymer, and
(b) at least one fatty phase comprising at least one wax, to impart to this composition better staying power over time and/or improved weighting and/or better resistance to crumbling and/or better lengthening of the eyelashes and/or an improved rate of drying.
These compositions are preferably in the form of an emulsion of the fatty phase in the aqueous phase or a dispersion of the aqueous phase in the fatty phase.
DETAILED DESCRIPTION OF THE INVENTION
Hitherto, dimethicone copolyols were known in various applications: as an emulsifying agent in compositions of the water-in-oil type, or alternatively as a plasticizer in hairstyling products. For example, EP-A-705,595, describes hairstyling compositions comprising a plasticizer, which may be a dimethicone copolyol or a polycarboxylic acid, in order to improve the flexibility of fixing resins.
However, the compositions described in EP-A-705,595, are very different in terms of their structure from compositions for making up the eyes. In particular, these compositions contain neither pigments nor fillers, nor do they contain large amounts of waxes. On reading that document, nothing would lead a person skilled in the art to think that the properties of lengthening of the eyelash, of adhesion to the eyelash, of weighting of the eyelashes, of staying power of the make-up and of resistance of the mascaras to mechanical stresses could he improved in a spectacular manner by the use of dimethicone copolyols.
The compositions according to the invention also advantageously contain at least one pigment, which may be selected from inorganic, organic and optionally pearlescent pigments. These pigments are preferably included in a proportion ranging from 0.25 to 25%, preferably from 1 to 20%, by weight relative to the total weight of the composition, depending on the coloration and intensity of the coloration which it is desired to obtain. Among the pigments which can be used include the oxides of zinc, of iron or of chromium, ferric blue, carbon black and the lakes commonly employed which ate salts of acidic dyes.
The composition according to the invention thus comprises a silicone which may be an oxyalkylenated silicone.
Preferably, the oxyalkylenated silicones do not have C

The oxyalkylenated silicones are selected from compounds of general formula (I), also referred to as dimethicone copolyols:
in which formula:

p ranges from 1 to 30,
a ranges from 0 to 50,
b ranges from 0 to 50,
a+b is greater than or equal to 1,
x ranges from 1 to 5,
the number-average molecular weight being greater than or equal to 15,000 and preferably between 25,000 and 75,000.
Preferably, R

Preferably, oxyalkylenated silicones of general formula (I) are used which satisfy at least one, and preferably all, of the following conditions:
R

denote a methyl radical,
R

represents a hydrogen atom, a methyl radical or an acetyl radical, and preferably hydrogen,
p ranges from 8 to 20,
a is between 5 and 40 and preferably between 15 and 30,
b is between 5 and 40 and preferably between 15 and 30,
x is equal to 2 or 3,
n ranges from 20 to 600, preferably from 50 to 500 and even more preferably from 100 to 300.
Such silicones are described, for example, in U.S. Pat. No. 4,311,695, which is hereby incorporated by reference.
Dimethicone copolyols have been presented in particular by the company Dow Corning during the 17th International Congress of the I.F.S.C.C, of October 1992 and have been reported in the article “Water-soluble dimethicone copolyol waxes for personal care industry” by Linda Madore et al., pages 1 to 3.
These dimethicone copolyols me water-soluble polydimethylsiloxanes (PDMS) containing one or more ether functions (oxyalkylene, in particular oxyethylene and/or oxypropylene).
Such dimethicone copolyols are sold in particular by the company Goldschmidt under the name Abil B8851 or Abil B88183. Mention may also be made of compounds KF 351 to 354 and RF 615 A sold by the company Shin Etsu or DMC 6038 from the company Wacker.
The dimethicone copolyol derivatives which can be used in the invention are, in particular, dimethicone copolyols containing a phosphate, sulphate, propyldimethylammonium myristamide chloride, stearate, amine, glycomodified, etc, group. The compounds sold by the company Siltech under the name Silphos A100, Siltech amine 65, Silwax WDIS, myristamide silicone quat, or by the company Phoenix under the name Pecosil PS 100 may be used in particular as dimethicone copolyol derivatives.
It is also possible to use the derivatives sold by the company Wacker under the name VP 1661, or by the company Dow Corning under the name 2501 cosmetic wax.
The silicones most particularly preferred are, for example, those sold by the company Dow Corning under the trade name Q2-5220 and by the company Rhone-Poulenc under the name Mirasil DMCO.
When, in the context of the present invention, linear polysiloxane-polyoxyalkylene block copolymers me used, these preferably have the gener
