Description

The invention relates to cosmetic make-up compositions for application to lips and skin.

Cosmetic compositions are generally defined as compositions suitable for application to the human body. Cosmetic compositions such as creams and lotions are used to moisturise skin and keep it in a smooth, supple condition. Pigmented cosmetic compositions such as make-up, for example, concealer, blusher, eye shadow, foundation, lipstick, etc. are used to colour or tint the skin and lips. Since adding colour is one of the most important reasons for wearing cosmetics, colour-containing cosmetics need to be very carefully formulated to provide maximum wear and effect.

JP61065809 seeks to provide a cosmetic which has excellent anti-running properties i.e. it has excellent water and oil resistance and good durability. The cosmetic comprises an organic silicone resin, a volatile oil and powder.

JP61158913 seeks to provide cosmetics which have good moisture resistance, perspiration resistance, oil resistance and lasting qualities. The cosmetics comprise an organic silicone resin, a volatile hydrocarbon oil and powder.

EP 0515195 A discloses liquid silicone esters. It exemplifies the use of these esters in compositions which contain substantial amounts of water and mentions that the esters exhibit improved water-resistance and greater substantivity.

Similarly HAPPI Household & Personal Products Industry, 29 (9): 44,113 (1992) discloses liquid silicone esters, in particular lauric and isostearic acid-based silicone esters. It states that these silicone esters have high substantivity.

US 5051489 A discloses silanol fatty ester compounds. These compounds are made by esterifying a fatty acid or carboxylic acid ester or anhydride with a silanol compound. They have lubricity and hydrophobicity.

JP 55028906 A relates to silicon waxes made from a siloxane and a fatty acid for use in lipsticks.

US 3764537 A relates to a synthetic petrolatum composition comprising polypropylene.

One of the long-standing problems with make-up, particularly lipstick, is the tendency of the cosmetic to blot or transfer from the skin onto other surfaces such as glassware, silverware, clothing, etc. This not only causes soiling of these surfaces, but forces the cosmetic wearer, especially lipstick user, to reapply cosmetic at fairly short intervals in order to maintain its effect, especially to keep the lips coloured.

Known cosmetics, particularly lipsticks, contain varying amounts of oil, wax and powder. However, all these hitherto-known compositions suffer from the disadvantages mentioned above.

It has now been found that incorporation of a volatile solvent and a silicone resin into such compositions mitigates the previously-mentioned disadvantages.

This invention therefore provides a cosmetic composition comprising oil, wax and powder, and optionally other excipients, characterised in that the composition comprises, by weight of the total composition,

(a) 1-70% volatile solvent having a viscosity substantially in the range of from 0.5 to 20 mPa.s at 25°C;
(b) 0.1-15% silicone ester wax which is lauryl trimethylolpropane siloxy silicate or isostearyl trimethylolpropane siloxy silicate, or a mixture thereof;
(c) 10-45% wax;
(d) 5-50% powder; and
(e) 1-30% oil.

The dependent claims specify preferred but optional features.

The composition of the invention provides a cosmetic composition which exhibits superior transfer resistance when compared with hitherto-known cosmetics.

In component (a), the term "volatile" means that the solvent has a measurable vapour pressure. The volatile solvents of the invention generally have a low viscosity, ranging from about 0.5 to 20 mPa.s at 25°C. Volatile solvents suitable for use in the compositions of the invention include volatile, low-viscosity silicone liquids such as cyclic silicones having the formula: wherein n is an integer of from 3 to 7. Volatile linear polydimethylsiloxanes are also suitable and generally have from about 2 to 9 silicon atoms and are of the formula: (CH₃)₃Si--O-[-Si(CH₃)₂--O-]_n--Si(CH₃)₃ wherein n is an integer of from 0 to 7. These silicones are available from various sources including Dow Corning Corporation, General Electric, etc. The Dow Corning cyclic silicones are sold under the tradenames Dow Corning 244, 245, 344, 345 and 200 fluids. These fluids comprise octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, hexamethyldisiloxane, or mixtures thereof. Also suitable as the volatile solvent are various C₈-C₂₀ isoparaffins such as C₁₂ isoparaffin made by The Permethyl Corporation having the registered trade mark Permethyl 99A (isododecane), distributed for The Permethyl Corporation by Presperse Inc., South Plainfield, New Jersey, U.S.A. Various C₁₆ isoparaffins are commercially available, such as isohexadecane (having the registered trade mark Permethyl 101A) and are also suitable. It is generally preferred that the volatile solvent component be a mixture of volatile silicones and C_8-20 isoparaffins. A ratio of from 10:1 to 1:10, respectively, is suitable. Preferably, the formulation comprises 35-60% of the volatile solvent. Therefore, a preferred formulation of the invention comprises 35-60% of a volatile solvent itself comprising a 10:1 to 1:10 ratio of cyclic silicones and C_8-20 isoparaffins.

For background information about silicone ester waxes reference may be made to US patent specification no. 4 725 658 which is incorporated herein by reference. The silicone ester waxes generally have a melting point of from about 40 to 90°C.

The waxes or wax-like materials (also known in the art as "waxes") of the invention generally have a melting point in the range of from 35-120°C. Waxes in this category include synthetic wax, ceresin, paraffin, ozokerite, illipe butter, beeswax, carnauba, microcrystalline, lanolin, lanolin derivatives, candelilla, cocoa butter, shellac wax, spermaceti, stearyl alcohol, bran wax, capok wax, sugar cane wax, montan wax, whale wax, bayberry wax, or mixtures thereof. Preferably, the formulation of the invention comprises about 10-30% wax, more preferably as a mixture of waxes.

The powder component of the invention is generally a dry, particulate matter having a particle size of 0.02-50 micrometres. The particulate matter may be coloured or non-coloured (for example, white) and, in particular, pigments are considered as "powder" for the purposes of this invention.

Suitable non-pigmented powders include bismuth oxychloride, titanated mica, fumed silica, spherical silica beads, polymethylmethacrylate beads, micronized teflon, boron nitride, acrylate polymers, aluminum silicate, aluminum starch octenylsuccinate, bentonite, calcium silicate, cellulose, chalk, corn starch, distomaceous earth, fuller's earth, glyceryl starch, hectorite, hydrated silica, kaolin, magnesium aluminum silicate, magnesium carbonate, magnesium hydroxide, magnesium oxide, magnesium silicate, magnesium trisilicate, maltodextrin, montmorillonite, microcrystalline cellulose, rice starch, silica, talc, mica, titanium dioxide, zinc laurate, zinc myristate, zinc neodecanoate, zinc rosinate, zinc stearate, polyethylene, alumina, attapulgite, calcium carbonate, calcium silicate, dextran, kaolin, nylon, silica silylate, silk powder, serecite, soy flour, tin oxide, titanium hydroxide, trimagnesium phosphate, walnut shell powder, or mixtures thereof. The above-mentioned powders may be surface-treated with lecithin, amino acids, mineral oil, silicone oil or various other agents, either alone or in combination, which coat the powder surface and render the particles hydrophobic in nature.

The powder component may also comprise various organic and inorganic pigments. The organic pigments are generally various aromatic types including azo, indigoid, triphenylmethane, anthraquinone, and zanthine dyes which are designated as D&C and FD&C blues, browns, greens, oranges, reds, yellows, etc. Inorganic pigments generally consist of insoluble metallic salts of certified colour additives, referred to as the Lakes or iron oxides.

The percentage of pigments used in the powder component will depend upon the type of cosmetic being formulated. Blushers, eyeshadows, lipsticks and similar cosmetics will contain higher percentages of pigment in the powder phase, usually ranging from 5-50% of the total cosmetic composition. Generally, the powder:pigment ratio ranges from 1:20 to 20:1.

Preferably, the invention comprises 10-30% of a powder component, especially wherein the non-pigment powder component comprises about 10-20% of the total composition and the pigment component comprises 1-10% of the total composition.

The composition of the invention also contains an oil, preferably comprising a mixture of low viscosity and high viscosity oils.

Suitable low viscosity oils have a viscosity of 5 to 100 mPa.s at 25°C, and are generally esters having the structure RCO-OR' wherein RCO represents a carboxylic acid radical and wherein OR' is an alcohol residue. Examples of these low viscosity oils include isotridecyl isononanoate, PEG-4 diheptanoate, where PEG-4 is a polymer of ethylene oxide of formula H(OCH₂CH₂)_nOH wherein n has an average value of 4, isostearyl neopentanoate, tridecyl neopentanoate, cetyl octanoate, cetyl palmitate, cetyl ricinoleate, cetyl stearate, cetyl myristate, coco-dicaprylate/caprate, decyl isostearate, isodecyl oleate, isodecyl neopentanoate, isohexyl neopentanoate, octyl palmitate, dioctyl malate, tridecyl octanoate, myristyl myristate, dioctyl malate ester, octyldodecanol, or mixtures of octyldodecanol, acetylated lanolin alcohol, cetyl acetate, isododecanol, polyglyceryl-3-diisostearate, or mixtures of any of these.

Suitable high viscosity surface oils generally have a viscosity of 200-1,000,000 mPa.s at 25°C, preferably a viscosity of 100,000-250,000 mPa.s at 25°C. Surface oils include castor oil, lanolin and lanolin derivatives, triisocetyl citrate, sorbitan sesquioleate, C_10-18 triglycerides, caprylic/capric/triglycerides, coconut oil, corn oil, cottonseed oil, glyceryl triacetyl hydroxystearate, glyceryl triacetyl ricinoleate, glyceryl trioctanoate, hydrogenated castor oil, linseed oil, mink oil, olive oil, palm oil, illipe butter, rapeseed oil, soybean oil, sunflower seed oil, tallow, tricaprin, trihydroxystearin, triisostearin, trilaurin, trilinolein, trimyristin, triolein, tripalmitin, tristearin, walnut oil, wheat germ oil, cholesterol, or mixtures thereof.

The ratio of low viscosity to high viscosity oils in the oil phase is preferably in the range of from 1:15 to 15:1, more preferably 1:10 to 10:1, respectively. The preferred formulation of the invention comprises 1-20% of a mixture of low viscosity and high viscosity surface oils.

Especially preferred compositions are those comprising:

a) 35-60% of the volatile solvent;
b) 3-10% of the silicone ester wax which is lauryl trimethylolpropane siloxy silicate or isostearyl trimethylolpropane siloxy silicate, or a mixture thereof;
c) 10-30% of the wax;
d) 10-30% of the powder component comprised, by weight of the total composition, of 10-20% non-pigment powder and 1-10% pigment powder; and
e) 5-20% of a mixture of low viscosity and high viscosity surface oils.

Other ingredients may also be added to the above composition including various types of amorphous or atactic polypropylene, and preservatives or antioxidants, and the like.

Preferably, amorphous or atactic polypropylene is incorporated in the range of from about 0.1-10%. Suitable polypropylenes are atactic polypropylenes having about 50-100% atactic content, 0.1-15% crystallinity, and a molecular weight of about 1,000-10,000 wherein the term "molecular weight" means average number molecular weight; the term "atactic content" means that the polypropylene polymeric structure is random or without orientation, as opposed to isotactic or syndiotactic polymers which exhibit specific orientation and structural regularity. Isotactic and syndiotactic polymers, due to their structural regularity, can easily cross-link to form a crystalline network whereas the structural irregularity of atactic polymers precludes appreciable polymeric cross linking: and the term "crystallinity" refers to the degree of cross-linking of the polypropylene polymer. Crystallinity is directly proportional to the degree of polymeric cross-linking, and polymers which exhibit extensive cross-linking are highly crystalline in nature.
