Title: A personal care composition

Description:
FIELD OF THE INVENTION 
     The invention relates to a personal care composition. The invention more particularly relates to a personal care composition that provides the excellent sensorial of vanishing creams while ensuring sun protection and good make-up effectiveness from the high amounts of pigments incorporated therein. 
     BACKGROUND OF THE INVENTION 
     Creams are a very commonly used form of cosmetic vehicle for delivery of actives for personal care benefits. Various different types of creams are available and each type of cream provides a different sensorial property. Consumers living in hot, humid climates, or consumers with oily skin, desire personal care products that have unique tactile properties during use. Specifically, such products should, upon application to the skin, deliver a high skin friction and a matte finish to overcome the oily skin feel and shiny skin appearance. The greater the increase in skin friction, the less greasy the user perceives the product to be. More specifically, the typical sensory and optical features of these high skin friction and matte finish creams, also known as vanishing creams, provide a dry, draggy, non-greasy feel to skin; provide a non-shiny, matte finish; spread easily on the skin; and absorb or “vanish” rapidly into the skin. 
     Traditionally, vanishing creams contain high levels of fatty acid (e.g. stearic acid or palmitic acid or a mixture of these) and alkali metal soap as an emulsifier, which is important for the physical stability of the product. The soap is formed by the in situ neutralization with caustic potash or other alkali on a portion of the fatty acid. In the past, vanishing creams are typically claimed to contain 1 to 25%, preferably 5 to 20% fatty acid and 0.1 to 10%, preferably 0.1 to 3% soap. While the above broad range of fatty acid and soap may be generally disclosed, the vanishing cream sensorial heretofore are obtained when the mole ratio of the soap to fatty acid is less than 0.22. 
     In addition to the cosmetic vehicle, personal care compositions usually comprise other actives which provide physical or biological protection or benefit to the skin e.g. photoprotection, skin lightening, anti-inflammatory benefits, anti-acne and other anti-microbial benefits among a host of other advantages. Photoprotection and make up/beautifying benefits are often highly sought after. Photoprotection is desired for protecting the skin from solar radiation which includes ultraviolet (UV) radiation, wavelength of which is between 200 nm and 400 nm. Exposure of skin to UV-A (320 to 400 nm) and UV-B (290 to 320 nm) causes various problems like reddening of the skin, localized irritation, sunburn, melanoma and formation of wrinkles. Therefore, it is desirable to protect the skin and other keratinous substrates of the human body from the harmful effects of both UV-A and UV-B radiation. 
     Photoprotection may be delivered through incorporation of organic sunscreens or inorganic sunblocks or a combination of the two. Commonly known inorganic sunblocks include titanium dioxide and/or zinc oxide which may be tailored for specific use through use of different particle sizes, surface morphologies or surface coatings or through tailored hollow sphere technologies to render the desired optical and photoprotection benefits. Beautifying/make up benefits are delivered through use of specific dyes or pigments which give the skin a desired even skin tone. Dyes are generally organic compounds and are usually water soluble which impart colour to the desired substrate. Pigments are generally inorganic compounds and are usually water insoluble and they too provide colour to the desired substrate. Due to the sensitive nature of skin against irritation and other inflammatory causing triggers, pigments are generally preferred for inclusion in personal care products for imparting make-up benefits to the skin especially on the face. Pigments come in various colours like blue, red, brown, yellow, black and even white. 
     The present inventors embarked upon developing a personal care composition through a vanishing cream base which would provide good photoprotection and excellent make up property through use of pigments. WO2015/018606A1 (Unilever) discloses a cosmetic composition comprising fatty acid, fatty acid salt, and pigment, wherein the cation of fatty acid salt comprises inorganic cation and organic ammonium, and the total amount of fatty acid and fatty acid salt is at least 5% by weight of the composition. 
     The present inventors found that when high amounts of such pigments or inorganic particles were included in the traditional vanishing creams the above mentioned sensorial properties are compromised. Using all the teachings of published information they were not able to solve the above problem. So, through extensive experiments they came up with the inventive understanding that this problem can be solved by manipulating the mole ratio of the soap to fatty acid, at higher values in order to not only give the desired photoprotection and make-up benefits but also have the consumer desired vanishing cream base sensorial. Another problem faced by the inventors was the instability of the composition in terms of sedimentation of the inorganic particles in the traditional vanishing creams. Surprisingly the solution in terms of the inventive mole ratio ranges also solved the instability problem thereby providing a personal care composition that delivers the desired consumer benefits while not compromising on the product stability and tactile sensorial on topical application of the product. By high amounts of such pigments or inorganic particles is meant that the total amount of these particulate matter is in the range of 2 to 8%, preferably 3 to 6%. It was observed that compositions having particulate matter less than the above amounts generally do not face such sensorial or instability problems. 
     It is thus an object of the present invention to obviate the drawbacks of the prior art and provide a stable vanishing cream composition where high amounts of inorganic particulates can be incorporated. 
     Another object of the present invention is to achieve the above object while ensuring that the desired vanishing cream sensorial is not compromised. 
     It is yet another object of the present invention to achieve both of the above objects while obtaining the storage stability of the composition in terms of even suspension of the particulates over long period of time. 
     SUMMARY OF THE INVENTION 
     The present invention provides for a personal care composition comprising:
     (a) 6 to 17% by weight of a C12 to C20 fatty acid;   (b) 2 to 6% by weight of a C12 to C20 fatty acid soap;   (c) 2 to 8% by weight of a white pigment; and   (d) a cosmetically acceptable carrier;
 
wherein the mole ratio of the soap to fatty acid is from 0.23 to 0.5.
   

     It is preferred that the composition further comprises a coloured pigment. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     These and other aspects, features and advantages will become apparent to those of ordinary skill in the art from a reading of the following detailed description and the appended claims. For the avoidance of doubt, any feature of one aspect of the present invention may be utilized in any other aspect of the invention. The word “comprising” is intended to mean “including” but not necessarily “consisting of” or “composed of.” In other words, the listed steps or options need not be exhaustive. It is noted that the examples given in the description below are intended to clarify the invention and are not intended to limit the invention to those examples per se. Similarly, all percentages are weight/weight percentages unless otherwise indicated. Except in the operating and comparative examples, or where otherwise explicitly indicated, all numbers in this description and claims indicating amounts of material or conditions of reaction, physical properties of materials and/or use are to be understood as modified by the word “about”. Numerical ranges expressed in the format “from x to y” are understood to include x and y. 
     When for a specific feature multiple preferred ranges are described in the format “from x to y”, it is understood that all ranges combining the different endpoints are also contemplated. 
     By a personal care composition as used herein, is meant to include a composition for topical application especially to the sun-exposed areas of the skin of mammals, especially humans. Such a composition may be generally classified as leave-on or rinse off, and includes any product applied to a human body for also improving appearance, cleansing, odor control or general aesthetics. It is more preferably a leave-on product. The composition of the present invention is in the form of a cream which may be applied to the desired skin surface using ones fingers or hands or applied with an implement or via a face mask, pad or patch. Non-limiting examples of such sunscreen compositions include leave-on skin creams, antiperspirants, and deodorants. “Skin” as used herein is meant to include skin on the face and body (e.g., neck, chest, back, arms, underarms, hands, legs, buttocks and scalp) and especially to the sun exposed parts thereof. 
     By a white pigment as per this invention is meant an inorganic particulate material which is visibly white in colour. 
     By a coloured pigment as per this invention is meant an inorganic particulate material which is not visibly white in colour. Coloured pigment as per this invention is preferably an inorganic particulate material which is visibly black, brown, pink, orange, red, yellow or blue in colour, or a combination of these colours. 
     By way of the present invention, the consumer is delivered the benefit of the excellent sensorial of a vanishing cream through which skin may be moisturised and given an instant even tone as well as photoprotection. Additionally, by way of appropriate benefit agents, skin lightening may be delivered to the consumer. 
     The composition of the invention comprises a fatty acid and a soap which are the key ingredients of a vanishing cream base. C 12  to C 20  fatty acids are present in 6 to 17%, preferably 8 to 15% by total weight of the composition. When the composition is being prepared, higher amounts of fatty acid may be added but a percentage of this is in-situ neutralised through use of an alkali metal hydroxide. When the neutralisation reaction is complete, it is expected that the amount of fatty acid remaining (un-neutralised) is in 6 to 17% by total weight of the composition. The fatty acids may be saturated or unsaturated fatty acids. While C 12  to C 20  fatty acids may be used, it preferred that C 14  to C 18  fatty acids are used. More preferably, the fatty acid is stearic acid or palmitic acid or a mixture of the two. The fatty acid in the present invention is preferably prepared using hystric acid which is substantially (generally about 90 to 95%) a mixture of stearic acid and palmitic acid in a ratio of between 55:45 to 45:55. Soap in the present invention is generally prepared by in-situ neutralisation of the fatty acid stock added to the reaction mixture. Thus, it is preferred that the soap has a carbon chain length which corresponds to the chain length of the free fatty acid in the composition. Soap is present in 2 to 6%, preferably 3 to 6% by total weight of the composition. The soap is formed from the fatty acid through use of alkali metal hydroxides like sodium or potassium hydroxide. Of the two, potassium hydroxide is more preferred. Thus the soap is preferably a potassium soap (potassium salt of fatty acid). 
     By the term ‘mole ratio of soap to fatty acid’ is meant mole of soap per mole of fatty acid remaining in the composition. Thus, if 1 mole of fatty acid is taken and neutralized with an alkali to form 0.2 moles of soap and if 0.8 moles of fatty acid is remaining in the composition, then the mole ratio of soap to fatty acid is 0.2/0.8=0.25. It is important that the mole ratio of the soap to the fatty acid in the composition after the neutralisation reaction is complete is in the range of 0.23 to 0.5, preferably 0.25 to 0.42. Generally, traditional vanishing creams have the mole ratio of soap to fatty acid less the 0.23. Use of these higher mole ratios have advantageously been used in the present invention to surprisingly provide the benefits summarised hereinabove especially when the composition comprises inorganic white pigments like titanium dioxide and in a preferred aspect inorganic coloured pigments. When the ratio is expressed as a weight ratio of soap to fatty acid, the composition preferably has a weight ratio of soap to fatty acid in the range of 0.26 to 0.55 preferably 0.28 to 0.45. Thus, the extent of neutralization of the fatty acid added into the reaction mixture, in the present invention, is at least 19% and could be up to 33% but is preferably up to 30%, while traditional vanishing creams have been prepared with the extent of neutralisation of less than 19%, often less than 18%. To achieve the extent of neutralisation, in the present invention, the stock of fatty acid mixture in the reaction vessel is dosed with alkali metal hydroxide of from 0.4 to 1%, preferably 0.5 to 0.7% by weight of the composition. 
     The composition of the invention comprises 2 to 8% white pigment. Traditionally, such inorganic particulates are included in 0.1 to at most 2%, often 0.1 to 1%. The inclusion of high amounts of white pigments as in the present invention makes it difficult to meet the desired sensorial of a vanishing cream while ensuring even dispersion of the particles in the composition at the manufacturing and transit conditions and during storage on the retail and consumer shelf. The above problem has been solved by way of the selective mole ratio defined above while ensuring that the benefit agents included therein perform as they are expected in their native state. The composition of the invention comprises 2 to 8% white pigment which generally have a refractive index higher than 1.8. The refractive index of the white pigment may be as high as 3.0. Preferred range of refractive index of the white pigment is from 1.8 to 2.2. Suitable white pigment which may be included as per the above criterion are zinc oxide, or titanium dioxide. More preferred white pigment is titanium dioxide. The amount of white pigment that is incorporated in the composition is preferably 3 to 6%, more preferably 4 to 6% by weight of the composition. The white pigment preferably has an average particle size in the range of 100 nm to 1 micrometer, more preferably from 300 nm to 1 micrometer. The white pigments may preferably be hydrophobically coated. Suitable hydrophobic coating materials are aluminium stearate, silicones or ferric stearate. 
     The composition of the invention preferably comprises a coloured pigment. A coloured pigment is generally an inorganic particulate material that is visibly coloured e.g. having a red, pink, brown, orange, yellow, blue or black colour. The coloured pigment as per the present invention preferably is red, yellow or black or a combination of these, most preferably a combination of all three of these coloured materials. Most preferred coloured pigment as per the present invention is iron oxide. The coloured pigment is preferably present in 0.1 to 2%, more preferably 0.5 to 1.5% by weight of the composition. Of the various colours, the yellow pigment preferably predominates and is preferably present in 0.05 to 1.2%, while the red pigment may be present in 0.01 to 0.3%, while the black pigment may be present in 0.01 to 0.2% by weight of the composition. The coloured pigment may also optionally be coated. Suitable coating materials are fatty acid or fatty acid salts, preferably stearic acid, polyhydroxystearic acid or a stearate. The coloured pigment preferably has an average particle size in the range of 100 nm to 1 micrometer, more preferably from 300 nm to 1 micrometer. 
     In addition to the pigments, the composition may comprise inorganic sunblocks. Inorganic sunblocks that may be incorporated include titanium dioxide or zin oxide, the particle size of which is generally below 100 nm in primary particle size. It is preferred that the total inorganic particles in the composition of the invention is less than 10 wt %, preferably less than 8 wt %.

     The data in Table-1 indicates that Examples outside the invention (Examples 1 to 3) where the mole ratio of soap:fatty acid was less than 0.23) exhibited poor stability in that the samples showed phase separation. The examples as per the invention (Examples 4 to 9) where the mole ratio of soap:fatty acid is higher than 0.23 demonstrated good stability. Further, samples of Examples 4 to 9 exhibited good vanishing cream sensory when rubbed on to skin. 
     Example 4 and A: Results of a Consumer Trial with a Composition as Per the Invention as Compared to a Market Sample 
     Example 4: A Composition as Per Example-4 (Table-1) was Used in the Consumer Trial 
     Example A: is a popular skin care cream available in the market which (from the back of pack information) is known to contain titanium dioxide (white pigment), iron oxides (coloured pigment), niacinamide (skin lightening agent), and thickeners and emollients that in combination is claimed to give fairer looking skin, an even tone of the skin with instant benefits. 
     The above two samples were tested in a consumer trial with about 200 consumers in the city of Mumbai, India. 109 users used sample of Example-4 and another (separate) group of 100 consumers used sample of Example A. The consumers gave their feedback on the attributes (see Table-2) of the respective products after they used the creams, once a day, for 14 days. 
     The consumers then rated the products that they used on various attributes and the summary of their preference is shown in Table-2 below. The numbers in the Table-2 is the percentage of people, who used the product, who agreed with the attribute indicated.

     The data in Table-2 above indicates that composition as per the present invention (Example-4) is vastly superior in terms of sensorial properties as well as functional skin lightening benefits, as is evident from the percentage of consumers who prefer the respective attributes. 
     The present invention thus provides a stable vanishing cream composition where high amounts of inorganic particulates can be incorporated while ensuring the desired vanishing cream sensorial. Additionally the composition delivers the desired skin benefit agents sufficiently well to be consumer perceivable.
