ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a cosmetic composition which can be used for caring for and/or for making up the human face, in particular, the skin, eyelids, or lips.
BACKGROUND OF THE INVENTION
Cosmetic compositions such as lipsticks and foundations generally comprise fatty substances, such as oils, pasty compounds and waxes, as well as a particulate phase generally composed of fillers and of pigments. These compositions can also contain cosmetic or dermatological active principles (vitamins, screening agents, moisturizers). However, when applied on the skin, eyelids, or lips, these compositions exhibit the disadvantage of transferring. In other words, the composition is deposited, at least in part, on certain substrates with which it is brought into contact, such as, for example, a glass or cup, an item of clothing, or the skin. On being deposited, the composition leaves a mark on the substrate. The result is thus a mediocre persistence of the composition on the skin, eyelids, or lips, requiring it to be reapplied regularly. Moreover, the appearance of unacceptable marks on certain items of clothing and in particular on the collars of shirts or blouses might dissuade some consumers from using this type of makeup.
Another disadvantage of these compositions lies in the problem of migration. It has been found that certain cosmetic compositions have a tendency to spread into the fine lines and/or wrinkles of the skin, in the case of foundations; into the fine lines which surround the lips, in the case of lipsticks; and into the folds of the eyelid, in the case of eyeshadows. Streaks in the makeup may also occur, particularly in the case of eyeshadows due to the movements of the eyelids.
All these phenomena produce an unsightly effect which it is very clearly desirable to avoid.
For a number of years, cosmetic scientists have been interested in long-wearing cosmetic compositions, in particular lipstick or foundation compositions. Some of these compositions contained silicone derivatives which, when combined with other ingredients, resulted in a lipstick which, although longer-wearing than previous lipsticks, left an uncomfortable dry, tight feeling on the lips. Additionally the long-wearing cosmetic compositions generally had a matte finish rather than the more desirable shiny finish. The art has continued to search for a composition combining moisturizing and long-wearing attributes.
SUMMARY OF THE INVENTION
Now, the inventors have discovered, unexpectedly and surprisingly, a long-wearing cosmetic composition which provides a film which substantially does not transfer or migrate and which additionally exhibits improved properties with respect to those of the long-wearing products of the prior art, in particular moisturizing, softening, and shine.
In order to achieve these and other advantages, the present invention is drawn to a cosmetic compositions comprising at least one wax, at least one ester, and at least one long chain alcohol. The composition may further comprise at least one film-forming agent and at least one volatile silicone derivative. In addition, the composition of the invention contains substantially no fluorinated oils.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Waxes
The waxes that may be used in the present invention include, but are not limited to, waxes of animal, vegetable, mineral and synthetic origin, such as ozokerite, candelilla, and carnauba waxes, polyethylene waxes, microcrystalline waxes, silicone waxes, paraffin, petrolatum, montan wax, beeswax, Japan wax, ouricury wax, lanolin and its derivatives, cocoa butter, sugarcane or cork fiber waxes, hydrogenated oils which are solid at 25° C., waxes obtained by the Fisher-Tropsch synthesis, and mixtures thereof. Preferably, the waxes used in the present invention have a melting point greater than 45° C. and are selected from ozokerite, available as, for example, OZOKERITE 170 from Strahl and Pitsch, microcrystalline wax, available as, for example, MULTIWAX W-445 from Witco, and polyethylene, available as, for example, PERFORMALENE 400 from New Phase Technologies. The at least one wax of the invention is preferably present in an amount of from about 1% to about 35%, including about 1% to about 30%, about 1% to about 25%, or about 3% to about 20%.
An ethylene homopolymer or ethylene copolymer having a melting point of 30 to 135° C. may be used. Such ethylene homopolymer or ethylene copolymer will have a molecular weight ranging from about 100 to about 2,000. Preferably the ethylene copolymers are comprised of ethylene monomer units of the following formula:
CH
2
═CH—R
1
wherein R
1
is a C
1-30
straight or branched chain saturated or unsaturated alkyl, aryl, or aralkyl, preferably a C
1-10
straight or branched chain alkyl. Examples of ethylene homo- and copolymers which may be used in the invention are set forth in U.S. Pat. No. 5,556,613, which is hereby incorporated by reference.
Esters
The esters that are useful in the presently claimed composition are esters obtained from acids having at least 4 carbon atoms such as, but not limited to, citric acid, octanoic acid, palmitic acid, hydroxystearic acid, stearic acid, oleic acid, arachidonic acid, myristic acid, and isostearic acid. These esters include C
12-22
fatty esters of citric acid. Preferred esters include, but are not limited to, citrate esters, dipentaerythrityl esters, and dilinoleate esters. Particularly preferred esters are dipentaerythrityl tetrahydroxystearate/isostearate, triisostearyl citrate and mixtures thereof. Dipentaerythrityl tetrahydroxystearate/isostearate is available, for example, from Nisshin Oil Mill under the trade name COSMOL 168E. The at least one ester of the invention is preferably present in an amount ranging from about 5% to about 40%. Where two esters are used, the combined amount may range from about 10% to about 60%. In a preferred embodiment, triisostearyl citrate is used in an amount of 5% to about 19% by weight, and optionally dipentaerythrityl tetrahydroxystearate/isostearate in an amount of 10% to about 20% by weight.
Long Chain Alcohols
The long chain alcohols useful in the presently claimed invention preferably have at least 8 carbon atoms in a linear or branched chain. Preferably, the long chain alcohols useful in the claimed invention contain from 12 to 48 carbon atoms. Such long-chain alcohols include, but are limited to, octyldodecanol, octyltetradecanol, octahexadecanol, oleyl alcohol, linoleyl alcohol, linolenyl alcohol, cetyl alcohol, lauric alcohol, lauryl glycol, hexadecylic alcohol, and isostearyl alcohol. Octyldodecanol, available from Henkel as EUTANOL G, is particularly preferred. The at least one long chain alcohol of the invention is preferably present in an amount ranging from 1 to 40%. The straight or branched chain fatty alcohols may also be used in amounts of from about 1% to about 35%.
Film-forming Agents
Film-forming agents which can be used in the inventive composition may be selected from any film-forming agents commonly known in the art. Among the film-forming polymers which may be used, mention may be made of synthetic polymers, polymers of natural origin and mixtures thereof. Preferably, the film-forming agent is a polyvinyl pyrrolidone (PVP) copolymer such as GANEX V216 (PVP/hexadecene), GANEX V220 (PVP/eicosene), or GANEX WP 660 (PVP/tricontanyl), available from ISP, or a polypropylene glycol/sodium maleic acid diisobutylene copolymer such as POLYOLPREPOLYMER-2 (PPG-12/SMDI) and POLYOLPREPOLYMER-14 (PPG-51/SMDI), available from Penederm Inc. It has been found that the combination of the film-forming agent with the long chain alcohol, esters and wax results in a long-wearing lipstick which is moisturizing, softening, and has shine.
Evaporative Solvents
Although not necessary to achieve long-wearing properties, the composition may also include evaporative silicone solvents to further improve the long-wear properties of the cosmetic. Evaporative solvents are solvents which have a vapor pressure of at least 0.01 mm of Hg at 20° C. and a viscosity of
