1. Field of the Invention
The present invention relates to compositions useful for moisturizing keratinous materials which contain at least one polyol and at least one solid wax capable of stabilizing the at least one polyol in an anhydrous solid composition, for example, a solid wax having a hydroxyl value ranging from about 38 to about 48.
2. Description of the Background
Moisturizing compositions are known and widely used in the art. Their applicability ranges from providing moisture to lips, skin, hair, and/or nails as a treatment when they are dry or as a preventative or for the maintenance of the lips, skin, hair and/or nails as a part of an individual's routine regimen of hygiene. For example, lip care compositions are commonly used not only to provide a make-up effect, e.g., color, but also to protect, soothe and/or moisturize. Polyols, such as for example, glycerin are known humectants which provide a moisture benefit to the lips, skin, hair, and/or nails when applied. However, polyols, such as for example, glycerin are not particularly stable in those compositions, i.e., they leech out of the composition.
Therefore, there remains a need to stabilize glycerin thereby providing additional moisturizing compositions that provide an exceptional moisturizing effect with little or no adverse effects, such as irritation, when applied.
The inventors have discovered that exceptional moisturizing benefits can be achieved on keratinous material by applying a composition combining at least one polyol and at least one solid wax capable of stabilizing the at least one polyol in an anhydrous solid composition, for example, a solid wax having a hydroxyl value ranging from about 38 to about 48. In addition, the inventors have discovered that the addition of the at least one wax stabilizes the composition with at least one polyol.
Thus, the present invention provides a composition comprising moisturizing effective amounts of at least one polyol and at least one solid wax capable of stabilizing the at least one polyol in an anhydrous solid composition.
The invention also provides methods of providing a moisturizing benefit to an individual with the composition.
The invention also provides methods of making the composition.
The invention, in one embodiment, relates to cosmetic, dermatological, and pharmaceutical products containing a composition having moisturizing effective amounts of at least one polyol and at least one solid wax capable of stabilizing the at least one polyol in an solid composition. In a preferred embodiment, the composition is anhydrous.
The polyols used in the present invention are polyols that are used as humectants and/or moisturizers in skin care compositions. Examples include hydrophilic and comprise polyhydric alcohols, ethoxylated and propoxylated polyols, polysaccharides, and mixtures thereof. Preferred polyols/moisturizers are selected from glycerin, panthenol, hexylene glycol, propylene glycol, butylene glycol, alkanediols, polyethylene glycol, polypropylene glycol, sorbitol, and mixtures thereof. Most preferred is glycerin.
The polyol is incorporated into the composition such that when in combination with the solid wax it provides a moisturizing benefit to the skin, lips and/or keratinous material of the user greater than either the polyol or solid wax separately. This combination in a composition provides a moisturizing effect, which means an increase in perceived moisture on the lips, skin, hair or other keratinous materials after the composition of the invention is applied thereto. Without being limited to theory, it is believed that the hydroxyl groups of the solid wax interact with glycerin thereby increasing the stability of glycerin in the composition and ultimately provides better moisturizing effects.
In another embodiment, moisture can be determined empirically using devices designed to measure moisture content, such as the SkinChip® sensor (L'Oréal and STMicroelectronics) or Novameter™ (NovaTechnology, Gloucester, Mass.). Using such a moisture testing device, the keratinous material onto which the composition described herein has been applied can benefit from at least a 5% increase in moisture relative to the moisture prior to application, which includes at least 10%, 15%, 20%, 25%, 30%, 40%, 50%, all subranges and values there between, or more.
For example, the polyol may be present in amounts from 0.5 to 75% by weight of the composition, inclusive of 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, and 70% by weight of the composition, and all ranges and sub ranges there between. In a preferred embodiment, the polyol is present in an amount from about 1 to about 5%, including 2%, 3%, 4% and all ranges and subranges there between.
The solid wax capable of stabilizing the at least one polyol in an anhydrous solid composition, for example, is a solid wax having a hydroxyl value ranging from about 10 to about 70, including from about 15 to about 60, including from about 30 to about 50, including from about 38 to about 48, which also includes values of 15, 20, 25, 35, 40, 45, 55, 65 and all values and subranges there between. In one embodiment, the solid wax can be a hydroxy polyester wax which is derived from the natural fatty acids and synthetic fatty alcohols yielding a wax that mimics the complex polyester fraction of natural beeswax which gives beeswax its unique plastic properties. In a generally preferred example, the wax should be solid at room temperature (about 25° C.). For example, the waxes that are similar to natural beeswax are described in International Cosmetic Ingredient Dictionary and Handbook Vol. 2 (7th ed. 1999) and in EP 0887069 and U.S. Pat. No. 3,914,131, the contents of which are incorporated herein, may be used.
The stability of the at least one polyol when combined with the solid wax described herein can be measured visually after preparation of the composition. For example, in an anhydrous solid composition, such as a stick composition, an increase in stability is visually presented as a decrease in sweating on the surface of the stick or the number of droplets formed on the stick's surface. While increase and decrease are relative terms, one of skill in the art will recognize that the relevant comparison is made to a similar stick but formulated without the wax or different concentrations of the wax. In a preferred embodiment, the combination of the at least one solid wax and the at least one polyol results in a composition that does not exhibit any sweating or the appearance of droplets on the solid stick formulation.
In a preferred embodiment, the wax is the wax sold as Kester K82P (Koster Keunen, Inc.), which is made up of a range of hydroxyl polyesters with an average chain length of 66 carbon atoms, C20-40 alkyl hydroxystearyl stearate (CAS 151661-95-9).
The at least one solid wax is incorporated into the composition such that when it is in combination with the at least one polyol, the composition provides a moisturizing benefit to the skin, lips and/or keratinous material of the user greater than either the polyol or solid wax separately. For example, the wax may be present in amounts from 0.5 to 75% by weight of the composition, inclusive of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, and 70% by weight of the composition, and all ranges and sub ranges there between.
The invention applies not only to make-up products for at least one keratinous material such as lip compositions, lip pencils, foundations including foundations which may be cast in the form of a stick or a dish, concealer products, temporary tattoo products, eyeliners, mascara bars but also to body hygiene products such as deodorant sticks, and to care products and products for treating at least one keratinous material such as sunscreen and after-sun products which may be in stick form. The present invention may be in the form of mascara product including mascara bars, an eyeliner product, a foundation product, a lipstick product, a blush for cheeks or eyelids, a deodorant product, a make-up product for the body, a make-up-removing product, an eyeshadow product, a face powder product, a concealer product, a treating shampoo product, a hair conditioning product, a sun screen, colorant for the skin or hair, or skin care formula such as, for example, anti-pimple or shaving cut formulas. As defined herein, a deodorant product is a body hygiene product and does not relate to care, make-up, or treatment of keratin materials, including keratin fibers, skin, or lips.
For example, the composition of the present invention may be in a form chosen from a paste, a solid, a gel, and a cream. It may be an emulsion, such as an oil-in-water or water-in-oil emulsion, a multiple emulsion, such as an oil-in-water-in-oil emulsion or a water-in-oil-in-water emulsion, or a solid, rigid or supple gel, including anhydrous gels. In one embodiment, the composition of the invention is anhydrous. The composition of the invention may, for example, comprise an external or continuous fatty phase. In another embodiment, the composition of the invention is transparent or clear, including for example, a composition without pigments. The composition can also be in a form chosen from a translucent anhydrous gel and a transparent anhydrous gel. The composition can also be a molded composition or cast as a stick or a dish. The composition in one embodiment is a solid such as a molded stick or a poured stick.
The compositions may also contain one or more film-forming polymers.
The film-forming polymer of the compositions may be chosen from any silicone resin that has film forming properties and any other organic material with film forming properties.
The film forming polymer of the compositions according to the present invention may also be a non silicone film former. This non silicone film former may be chosen from, for example, polyethylene; vinylpyrrolidone/vinyl acetate (PVP/VA) copolymers such as the Luviskol® VA grades (all ranges) from BASF® Corporation and the PVP/VA series from ISP; acrylic fluorinated emulsion film formers including Foraperle® film formers such as Foraperle® 303 D from Elf Atochem (although Foraperle® may not be appropriate for some cosmetic formulations); GANEX® copolymers such as butylated PVP, PVP/Hexadecene copolymer, PVP/Eicosene copolymer or tricontanyl;
Poly(vinylpyrrolidone/diethylaminoethyl methacrylate) or
PVP/Dimethylaminoethylmethacrylate copolymers such as Copolymer 845; Resin ACO-5014 (Imidized IB/MA copolymer); other PVP based polymers and copolymers; alkyl cycloalkylacrylate copolymers (See WO 98/42298, the disclosure of which is hereby incorporated by reference); Mexomere® film formers and other allyl stearate/vinyl acetate copolymers (allyl stearate/VA copolymers); polyolprepolymers such as PPG-12/SMDI copolymer, polyolprepolymers such as PPG-12/SMDI copolymer, Poly(oxy-1,2-ethanediyl), α-hydro-ω-hydroxy-polymer with 1,1′-methylene-bis-(4-isocyanatocyclohexane) available from Barnet; Avalure™ AC Polymers (Acrylates Copolymer) and Avalure™ UR polymers (Polyurethane Dispersions), available from BFGoodrich.
The film former which also may be used within the framework of the invention includes film formers having any film former chemistry known in the art such as: PVP, acrylates, and urethanes; synthetic polymers of the polycondensate type or free-radical type, or ionic type, polymers of natural origin and mixtures thereof or any other film former known within the practice of the cosmetic and pharmaceutical arts which one skilled in the art may determine to be compatible. Film formers that may be used are also disclosed in the International Cosmetic Ingredient Dictionary and Handbook Vol. 2 (7th ed. 1999), more particularly the emollients disclosed on pages 1636-1638. The disclosure of the International Cosmetic Ingredient Dictionary and Handbook Vol. 2, pages 1636-1638, is hereby incorporated by reference.
An appropriate concentration of the film former may be determined by one of skill in the art and can vary considerably based on the application. For example, for cosmetic compositions, the film former may be used in an amount from 0.1% to 20% such as, for example, from 1% to 10% by weight, relative to the total weight of the composition.
Depending on the intended application, such as a stick, hardness of the composition may also be considered. The hardness of a composition may, for example, be expressed in grams (g). The composition of the present invention may, for example, have a hardness ranging from 20 g to 2000 g, such as from 20 g to 900 g, and further such as from 20 g to 600 g.
This hardness is measured in one of two ways. A first test for hardness is according to a method of penetrating a probe into said composition and in particular using a texture analyzer (for example TA-XT2 from Rhéo) equipped with an ebonite cylinder of height 25 mm and diameter 8 mm. The hardness measurement is carried out at 20° C. at the center of 5 samples of said composition. The cylinder is introduced into each sample of composition at a pre-speed of 2 mm/s and then at a speed of 0.5 mm/s and finally at a post-speed of 2 mm/s, the total displacement being 1 mm. The recorded hardness value is that of the maximum peak observed. The measurement error is ±50 g.
The second test for hardness is the “cheese wire” method, which involves cutting an 8.1 mm tube of composition and measuring its hardness at 20° C. using a DFGHS 2 tensile testing machine from Indelco-Chatillon Co. at a speed of 100 mm/minute. The hardness value from this method is expressed in grams as the shear force required to cut a stick under the above conditions. According to this method, the hardness of compositions according to the present invention which may be in stick form may, for example, range from 30 g to 300 g, such as from 30 g to 250 g, and further such as from 30 g to 200 g.
The hardness of the composition of the present invention may be such that the compositions are self-supporting and can easily disintegrate to form a satisfactory deposit on a keratinous material. In addition, this hardness may impart good impact strength to the inventive compositions which may be molded or cast, for example, in stick or dish form.
The skilled artisan may choose to evaluate a composition using at least one of the tests for hardness outlined above based on the application envisaged and the hardness desired. If one obtains an acceptable hardness value, in view of the intended application, from at least one of these hardness tests, the composition falls within the scope of the invention.
According to the present invention, the compositions in stick form may also possess the properties of deformable, flexible elastic solids and may also have noteworthy elastic softness upon application to a keratinous material.
The compositions of the present invention may also contain one or more volatile oils or solvents. For the purposes of the invention, the expression “volatile solvent or oil” means any non-aqueous medium capable of evaporating on contact with the skin or the lips in less than one hour at room temperature and atmospheric pressure. The volatile solvent(s) of the invention is(are) organic solvents, such as volatile cosmetic oils that are liquid at room temperature, having a non-zero vapor pressure, at room temperature and atmospheric pressure, ranging in particular from 10−2 to 300 mmHg and, for example, greater than 0.3 mmHg. The expression “non-volatile oil” means an oil which remains on the skin or the lips at room temperature and atmospheric pressure for at least several hours, such as those having a vapor pressure of less than 10−2 mmHg.
According to the invention, these volatile solvents may facilitate the staying power or long wearing properties of the composition on the skin, the lips or superficial body growths. The solvents can be chosen from hydrocarbon-based solvents, silicone solvents optionally comprising alkyl or alkoxy groups that are pendant or at the end of a silicone chain, and a mixture of these solvents.
The volatile oil(s), in one embodiment, is present in an amount ranging from 0% to 95.5% relative to the total weight of the composition, such as from 2% to 75% or, for example, from 10% to 45%. This amount will be adapted by a person skilled in the art according to the desired staying power or long wearing properties.
The compositions of the present invention may also contain one or more sun screening agents.
Sunscreens according to this invention which are chemical absorbers actually absorb harmful ultraviolet radiation. It is well known that chemical absorbers are classified, depending on the type of radiation they protect against, as either UV-A or UV-B absorbers. UV-A absorbers generally absorb radiation in the 320 to 400 nm region of the ultraviolet spectrum. UV-A absorbers include anthranilates, benzophenones, and dibenzoyl methanes. UV-B absorbers generally absorb radiation in the 280 to 320 nm region of the ultraviolet spectrum. UV-B absorbers include p-aminobenzoic acid derivatives, camphor derivatives, cinnamates, and salicylates.
Classifying the chemical absorbers generally as UV-A or UV-B absorbers is accepted within the industry. However, a more precise classification is one based upon the chemical properties of the sunscreens. There are eight major classifications of sunscreen chemical properties which are discussed at length in “Sunscreens—Development, Evaluation and Regulatory Aspects,” by N. Shaath et al., 2nd. Edition, pages 269-273, Marcel Dekker, Inc. (1997). This discussion, in its entirety, is incorporated by reference herein.
The sunscreens which may be formulated according to the present invention typically comprise chemical absorbers, but may also comprise physical blockers. Exemplary sunscreens which may be formulated into the compositions of the present invention are chemical absorbers such as p-aminobenzoic acid derivatives, anthranilates, benzophenones, camphor derivatives, cinnamic derivatives, dibenzoyl methanes (such as avobenzone also known as Parsol®1789), diphenylacrylate derivatives, salicylic derivatives, triazine derivatives, benzimidazole compounds, bis-benzoazolyl derivatives, methylene bis-(hydroxyphenylbenzotriazole) compounds, the sunscreen polymers and silicones, or mixtures thereof. These are variously described in U.S. Pat. Nos. 2,463,264, 4,367,390, 5,166,355 and 5,237,071 and in EP-0,863,145, EP-0,517,104, EP-0,570,838, EP-0,796,851, EP-0,775,698, EP-0,878,469, EP-0,933,376, EP-0,893,119, EP-0,669,323, GB-2,303,549, DE-1,972,184 and WO-93/04665, also expressly incorporated by reference. Also exemplary of the sunscreens which may be formulated into the compositions of this invention are physical blockers such as cerium oxides, chromium oxides, cobalt oxides, iron oxides, red petrolatum, silicone-treated titanium dioxide, titanium dioxide, zinc oxide, and/or zirconium oxide, or mixtures thereof.
