ABSTRACT:
The present invention concerns a composition, in particular a cosmetic composition capable of being applied on the skin and/or lips, and, in particular, an anhydrous composition for the care and/or make-up of the skin, and/or lips, especially a lipstick in stick form or a make-up foundation.
Lipstick and make-up foundation compositions normally contain fatty substances such as oils, viscous compounds and waxes, as well as particulate phase usually composed of fillers and pigments. When applied to the skin or lips, these compounds have the disadvantage of being transferred, that is, of forming a deposit, at least in part, while leaving a trace on objects with which they come into contact, in particular, a glass, a cup, a piece of clothing or the skin. Consequently, there remains on the skin or lips a reduced film which requires the periodic re-application of the make-up foundation or lipstick composition.
Furthermore, the appearance of unacceptable traces on clothing and, most especially, on the necks of blouses, may dissuade some women from using this type of make-up.
Another disadvantage of these compositions lies in the problem of migration. Indeed, it has been observed that some foundation compositions tended to spread inside wrinkles in the skin, that some lipstick compositions traveled in the small wrinkles surrounding the lips, while eye-shadows tended to spread in the folds of the eyelids. In the case of eye-shadows, the appearance of lines in the make-up, caused by movements of the eyelids, were also noted. All of these phenomena produced an unaesthetic effect which the consumer quite obviously wished to avoid.
For several years, many cosmeticians have been interested in lipsticks, and, more recently, make-up foundation compositions, that “did not transfer.” Thus, Patent Application No. JP-A-61-65809 disclosed “transferless” lipstick compositions containing 1 to 70% by weight of a liquid silicone resin incorporating repeating silicate patterns (or having a three-dimensional lattice) comprising alkylated suspended chains of 1 to 6 atoms of carbon or phenylated chains, 10 to 98% by weight of a volatile silicone oil having a cyclic Si—O chain and containing methyl radicals, and pulverulent fillers. These compositions, although highly satisfactory as regards the lack of transference, had the disadvantage of being in liquid form and thus inconvenient to use, or, at the very least, of being far removed from the conventional idea of a lipstick, thereby limiting the number of women prepared to use this type of lipstick. In addition, the film produced on the lips after evaporation of the silicone oil had the disadvantage of becoming uncomfortable over time (sensation of drying and tugging, thus dissuading still other women from using this type of lipstick). To enhance the comfort given by this type of composition, non-volatile oils, whether or not they contained silicone, could be added; however, in this case the “transferless” property is lost. Moreover, these compositions take a long time to dry: that is, the lack of transfer appears only after several minutes.
More recently, Patent Application No. EP-A-602905 disclosed “transferless” lipsticks containing a volatile cyclic or linear silicone containing suspended methylated chains and a silicone resin incorporating a suspended esterified chain having at least 12 atoms of carbon. The lipstick film still possesses the problem of being uncomfortable when applied and, most notably, of being too dry.
The invention in question is intended to propose a composition, in particular an anhydrous composition, for skin care or make-up making it possible to remedy these difficulties, while, in particular, allowing the production of a film that does not transfer or migrate and that does not stain an object with which it comes into in contact, while exhibiting improved cosmetic properties as compared with the properties of “transferless” products according to prior art, in particular smooth sliding, the absence of tugging, and the lack of drying of the lips.
Accordingly, the object of the invention is the use of the combination of a volatile oil and a silicone-containing phenylated oil in a composition containing a fatty phase, in order to reduce transfer and/or migration and/or to improve the holding power of this composition.
Another object of the invention is a composition containing, in a fatty phase, a volatile oil, a silicone-containing phenylated oil, and less than 20% by weight of a non-volatile hydrocarbonic oil, e.g., a foundation product.
The invention encompasses compositions to be applied to the skin, the semi-mucous membranes, e.g., the lips, and/or the mucous membranes, e.g., the internal areas of the eyelids, and, in particular, not only to lip make-up but also to lip-care products and to skin and rouge make-up and care products such as foundations. In fact, facial make-up products possess the same problems of “transfer” to an object as do lipsticks.
The composition according to the invention may exist in solid form, e.g., as a stick. Furthermore, it yields a homogeneous film that is easily applied and spreads smoothly and uniformly. The film produced also has a light texture and remains comfortable and moist, and can be worn throughout the day.
The invention composition thus comprises a volatile oil which can be chosen, in particular, from hydrocarbonic or silicone-containing oils, whether cyclic or linear, either alone or in mixtures. The term “volatile oil” in this description signifies any oil that can evaporate on contact with the skin. Preferably, use is made of oils whose flash point is sufficiently high to allow the use of these oils in formulations, and low enough to obtain the desired evanescent effect. Oils having a flash point of approximately 40-100° C. are preferably used.
Usable volatile silicone oils include cyclotetradimethylsiloxane, cyclopentadimethylsiloxane, cyclohexadimethylsiloxane, and methylhexyldimethylsiloxane. Among the volatile hydrocarbonic oils, isoparaffins may be mentioned.
The composition according to the invention may contain 8-70% by weight, and preferably 30-60%, volatile oils in relation to the total weight of the composition.
The composition according to the invention also contains at least one phenylated silicone oil. This oil may be a polyphenylmethylsiloxane or a phenyltrimethicone, or a mixture of different phenylated silicone oils, and, in particular, it may correspond to the following formula:
where:
R is an alkyl radical at C1-C30, an aryl radical, or an aralkyl radical
n is a whole number between 0 and 100,
m is a whole number between 0 and 100, provided that the sum m+n is between 1 and 100.
Preferably, R is a methyl, ethyl, propyl, isopropyl, decyl, dodecyl, or octadecyl radical, or a phenyl, tolyl, benzyl, or phenethyl radical.
Among these phenylated oils, mention may be made of Belsil PDM1000 oil from Wacker, DC556 and SF558 oils made by Dow Corning, Abil AV8853 oil made by Goldschmidt, and Silbione 70633V30 oil manufactured by Rhône Poulenc.
The composition according to the invention may contain 1-35% by weight, and preferably 20-30% by weight, phenylated silicone oils.
In addition to the oils cited above, the fatty phase may contain the fatty substances normally used in the contemplated scope of application. These substances include silicone-containing fatty substances such as oils, viscous fatty substances, silicone waxes, and non-silicone-containing fatty substances such as oils, viscous substances, and vegetable, mineral, animal, and/or synthetic waxes.
Silicone-containing fatty substances include polydimethylsiloxanes (PDMS) and alkyldimethicones, as well as silicones modified by potentially fluorinated aliphatic and/or aromatic groups or by functional groups, such as hydroxyl groups, thiols, and amines.
Among non-silicone-containing fatty substances, mention may be made of paraffin, vaseline, perhydrosqualene, arara oil, sweet almond oil, calophyllum oil, palm oil, castor oil, avocado oil, jojoba oil, olive oil, or cereal gerin oil; esters of fatty acids; alcohol
