Description
WO 00/48569 PCT/USOO/04084 Cosmetic Compositions Technical Field The present invention relates to cosmetic compositions. In particular it relates to cosmetic compositions comprising higher levels of Vitamin B 3 compounds with reduced irritation, 5 tack and skin whitening effects. Background of the Invention A variety of compounds have been described in the art as being useful for regulating fine lines, wrinkles and other forms of undesirable skin surface texture. In addition, Vitamin
B
3 compounds, particularly niacinamide, have recently been found to provide measurable 10 benefits in regulating skin condition, including regulating fine lines, wrinkles and other forms of uneven or rough surface texture associated with aged or photodamaged skin. However, many materials require multiple applications over an extended period to provide such appearance benefits. It would be additionally advantageous to provide a topical composition which provides a more immediate improvement in the appearance of 15 fine lines, wrinkles and other forms of undesirable skin surface texture, and also to effect an immediate improvement in the feel of the skin. One means of effecting a more immediate improvement on skin surface texture and feel would be to deliver high levels of Vitamin B 3 compounds, particularly niacinamide, from a topical composition. However, the delivery of high levels of niacinamide (greater than 20 1%) to the skin is complicated by niacinamide crystallisation at these levels on the skin surface. This is undesirable for the consumer who may observe skin whitening, an WO 00/48569 PCT/USOO/04084 2 increase in the stickiness of the product residue and experience irritation effects from localised concentrations of niacinamide crystals. Polymeric film forming agents such as polyquaternium-10 are described in US-A 5,103,763 as skin-feel-modifying compounds useful for skin care compositions which are 5 resistant to removal when the skin is washed. In addition, US-A-4,938,951 describes compositions comprising evaporative solvents, polymeric film forming agents, and topically active agents. The compositions are described as providing an enhancement in the effective activity of a topically active agent and specifically, that the film forming polymer has an ability to enhance the effective activity of the topically active agent. The 10 term "topically active agent" is said to include vitamins and example 47 discloses a composition comprising water, ascorbic acid (0.5%) and JR-400 (polyquatemium-10) (0.1%) in a ratio of polymer to agent of 0.2:1. The ratio of film forming agent to topically active agent in compositions therein is described as generally being from 0.5:1 to 20:1 and preferably from 1:1 or 2:1 to 4:1. Such high ratios of film forming agent to topically 15 active agent taught in this document are likely to produce high viscosity product residues which are undesirable from a consumer perspective. In addition, W097/39733 describes a method of regulating visible or tactile discontinuities in the texture of skin using a composition comprising a safe and effective amount of a vitamin B3 compound and a carrier for the active. Optional ingredients for 20 the compositions described therein are crosslinked and non-crosslinked nonionic and cationic polyacrylamides e.g. polyquaternium-32 and polyquaternium-37 and film forming polymers such as the copolymer of eicosene and vinyl pyrrolidone. Whilst the compositions and disclosures of the prior art provide useful advances in the art of cosmetic skin treatment, they do not adequately teach means to reduce the irritation, 25 skin whitening and tack displayed by compositions comprising higher levels of Vitamin B3 compounds. It has now been found that by incorporating selected cation containing polymers into a leave-on cosmetic composition comprising high levels of a Vitamin B3 compound at specific ratios, the sticky feel usually associated with higher levels of the latter compound 30 can be offset and further, a composition is provided with lower levels of irritation and WO 00/48569 PCT/US0O/04084 3 whitening. Without being limited by theory, it is thought that the incorporation of cation containing polymers into the composition at the specified ratios herein reduces the rate and pattern of this crystallisation leading to a more homogenous coverage of the skin surface with niacinamide crystalline material. The cationic groups on the polymer are 5 thought to bind to the crystal surfaces as they form, thereby slowing further growth and reducing the whitening and tack effects. Summary of the Invention According to one aspect of the present invention there is provided a leave-on cosmetic composition suitable for topical application to the skin comprising: a) from about 1% to about 20% of a Vitamin B 3 compound, or mixtures thereof and; b) a cation containing polymer selected from ampholytic, amphoteric, basic, zwitterionic and cationic polymers or mixtures thereof, wherein the cationic polymers are selected from cationic polysaccharides or derivatives thereof, cationic homo or copolymers of dimethyldiallylammonium chloride, cationic copolymers comprising vinylpyrrolidone; cationic copolymers comprising acrylic acid or derivatives thereof, N,N,N-trimethyl-2-[(2-methyl-1-oxo-2 propenyl)oxy]-,chloride, Polyquaternium-2, quaternised chitosan, or mixtures thereof; wherein said composition has a weight ratio of cation containing polymer to Vitamin B 3 compound of from 1:7 to 1:100. 10 The compositions of the invention display reduced irritation, tack and skin whitening effects. According to a second aspect of the present invention there is provided a cosmetic method of treatment of the skin comprising applying to the skin a composition according to the present invention. 15 According to a third aspect of the present invention there is provided a use of a cation containing polymer, or mixtures thereof, for reducing levels of tack, irritation or skin WO 00/48569 PCT/USOO/04084 4 whitening in a skin care composition comprising a Vitamin B 3 compound, or mixtures thereof. According to a fourth aspect of the present invention there is provided a use of a composition comprising a Vitamin B 3 compound, or mixtures thereof and a cation 5 containing polymer, or mixtures thereof wherein said composition has a weight ratio of cation containing polymer to Vitamin B 3 compound of from 1:7 to 1:100 for a leave-on skin care application. Detailed Description of the Invention The compositions of the present invention comprise a Vitamin B 3 or mixtures thereof, with an essential specified cation containing polymer component, or mixtures thereof, wherein said composition has a weight ratio of cation containing polymer to vitamin B 3 compound of from 1:7 to 1:100, as well as various optional ingredients as indicated below. All levels and ratios are by weight of total composition, unless otherwise indicated. Chain length and degrees of ethoxylation are also specified on a weight average basis. The term "tack" or "tackiness", as used herein, in relation to a leave-on composition 10 means the ability of a composition to lightly bond to skin surfaces where the composition has been applied, upon the application of light pressure and within a short time-scale. The term "stickiness" or "sticky" as used herein, is a term often used by consumers to describe their perception of the tack, either actual or perceived of a composition. As used herein the term "leave-on" in relation to skin care compositions means that it 15 intended to be used without a rinsing step, such that after applying the composition to the skin, the leave-on composition is preferably left on the skin for a period of at least about 15 minutes, more preferably at least about 30 minutes, even more preferably at least about 1 hour, most preferably for at least several hours, e.g., up to about 12 hours. The term "cation containing polymer" as used herein, means a polymer having 2% or 20 more, preferably 5% or more or more preferably 10% or more on a molar weight basis of monomers that contain cationic charge at pH 4.
WO 00/48569 PCT/US00/04084 5 The term "ampholytic" as used herein, means a polymer which comprises cationic and anionic monomers. The term "copolymer" as used herein, means the combination of more than one chemically different monomer. 5 The term "zwitterionic" as used herein, means a compound which bears both positive and negative charges and exists as a dipolar ion in a wide range of pH. The term "amphoteric" as used herein, means a compound which exhibits cationic behaviour at low pH and anionic behaviour at high pH. At intermediate pH, called the isoelectric point, the compound bears both positive and negative charges i.e. it is a dipolar 10 ion. The term "basic" as used herein, means a polymer which shows increasing cationic charge with decreasing pH. The term "skin conditioning agent", as used herein means a material which is capable of providing a cosmetic conditioning benefit to the skin such as moisturization, humectancy 15 (i.e. the ability to retain or hold water or moisture in the skin), emolliency, visual improvement of the skin surface, soothing of the skin, softening of the skin, and improvement in skin feel. The term "non-occlusive" as used herein, means that the component as so described does not substantially or block the passage of air and moisture through the skin surface. 20 The present compositions can be used for any suitable purpose. In particular, the present compositions are suitable for topical application to the skin. In particular, the skin care compositions can be in the form of creams, lotions, gels, and the like. Preferably the cosmetic compositions herein are in the form of an emulsion of one or more oil phases in an aqueous continuous phase. 25 Vitamin B 3 Compounds As an essential ingredient, the compositions of the present invention comprise at least one Vitamin B 3 compound. The compositions of the present invention preferably comprise from about 1% to about 20%, preferably from about 4% to about 15%, , more preferably from about 7% to about WO 00/48569 PCT/USOO/04084 6 14% and even more preferably from about 10 to about 13% of a Vitamin B 3 compound, or mixtures thereof. As used herein, "vitamin B 3 compound" means a compound having the formula: O)R N 5 wherein R is - CONH 2 (i.e., niacinamide), - COOH (i.e., nicotinic acid) or - CH 2 OH (i.e., nicotinyl alcohol); derivatives thereof; and salts of any of the foregoing. Exemplary derivatives of the foregoing vitamin B 3 compounds include nicotinic acid esters, including non-vasodilating esters of nicotinic acid, nicotinyl amino acids, nicotinyl alcohol esters of carboxylic acids, nicotinic acid N-oxide and niacinamide N-oxide. As 10 used herein, "non-vasodilating" means that the ester does not commonly yield a visible flushing response after application to the skin in the subject compositions (the majority of the general population would not experience a visible flushing response, although such compounds may cause vasodilation not visible to the naked eye, i.e., the ester is non rubefacient). Non-vasodilating esters of nicotinic acid include tocopherol nicotinate and 15 inositol hexanicotinate; tocopherol nicotinate is preferred. Other derivatives of the vitamin B 3 compound are derivatives of niacinamide resulting from substitution of one or more of the amide group hydrogens. Examples of derivatives of niacinamide useful herein include nicotinyl amino acids, derived, for example, from the reaction of an activated nicotinic acid compound (e.g., nicotinic acid azide or nicotinyl 20 chloride) with an amino acid, and nicotinyl alcohol esters of organic carboxylic acids (e.g., CI - C18). Specific examples of such derivatives include nicotinuric acid
(C

N
2 0 2 ). Exemplary nicotinyl alcohol esters include nicotinyl alcohol esters of the carboxylic acids salicylic acid, acetic acid, glycolic acid, and palmitic acid and the like. Other examples of vitamin B 3 compounds 25 useful herein are 2-chloronicotinamide, 6-methylnicotinamide, N-methyl-nicotinamide, and niaprazine.
WO 00/48569 PCT/US0O/04084 7 Examples of the above vitamin B 3 compounds are well known in the art and are commercially available from a number of sources, e.g., the Sigma Chemical Company (St. Louis, MO); ICN Biomedicals, Inc. (Irvin, CA) and Aldrich Chemical Company (Milwaukee, WI). 5 One or more vitamin B 3 compounds may be used herein. Preferred vitamin B 3 compounds are niacinamide and tocopherol nicotinate. Niacinamide is more preferred. Salts of the vitamin B 3 compound are also useful herein. Useful examples include organic or inorganic salts, such as inorganic salts with anionic inorganic species (e.g. chloride), and organic carboxylic acid salts. These and other salts of the vitamin B 3 10 compound can be readily prepared by the skilled artisan, for example, as described by W. Wenner, "The Reaction of L-Ascorbic and D-Isoascorbic Acid with Nicotinic Acid and Its Amide", J. Organic Chemistry, VOL. 14, 22-26 (1949), which is incorporated herein by reference. Wenner describes the synthesis of the ascorbic acid salt of niacinamide. In a preferred embodiment, the ring nitrogen of the vitamin B 3 compound is 15 uncomplexed, or after delivery to the skin becomes uncomplexed. More preferably, the vitamin B 3 compound is essentially uncomplexed. Therefore, if the composition contains the vitamin B 3 compound in a salt or otherwise complexed form, such complex is preferably substantially reversible upon delivery of the composition to the skin. Such complex should be substantially reversible at a pH of from about 5.0 to about 6.0. Such 20 reversibility can be readily determined by one having ordinary skill in the art. In a preferred embodiment, the vitamin B 3 compound typically contains less than about 50% of the compound in a salt form. The vitamin B 3 compound may be included as the substantially pure material, or as an extract obtained by suitable physical and/or chemical isolation from natural (e.g., plant) 25 sources. The vitamin B 3 compound is preferably substantially pure, by which is meant substantially free of impurities arising from the original source. Substantially pure compounds can be provided in solution, optionally with an anti-oxidant or other stabiliser.
