Title: High polyol wash composition

Description:
FIELD OF THE INVENTION 
     The present invention is directed to a stable, high polyol containing wash composition. More particularly, the invention is directed to a wash composition comprising polyol, surfactant and a gelling agent whereby the wash composition has excellent moisturizing capabilities, a viscosity of 40,000 cps or less, and a slope from −0.5 to 0.0. Surprisingly, the high polyol containing wash composition is homogeneous and substantially free of air pockets, even after shaking or agitation. Such wash composition is also substantially free of oil but isotopic with an oil-like appearance. 
     BACKGROUND OF THE INVENTION 
     Personal care compositions are typically employed to cleanse skin and to reduce shine associated with sebum produced in specialized epithelial cells known as sebocytes. They are also used to minimize bacteria on the hands and face such that washing is viewed as the most effective way to prevent the spread of germs and bacteria. In fact, experts believe that periodic washing throughout the day can reduce the number of consumers catching colds by about 50%. 
     Consumers typically prefer compositions which are not only mild to the skin but that also deliver benefit agents to skin. Such attributes entice consumers to wash more and reduce their fears that over washing will yield dry and flaky skin by stripping the skin of important natural elements, including oils. Additionally, consumers prefer not to use products that look and feel harsh, preferring products with an attractive appearance and natural ingredi-ents. 
     The present invention, therefore, is directed to a stable, high polyol containing wash composition. The composition comprises a polyol, surfactant and a gelling agent whereby the wash composition has excellent moisturizing properties, a viscosity of 40,000 cps or less, and a slope from −0.5 to 0.0. Surprisingly, the high polyol containing wash composition is homogeneous and substantially free of air pockets, even after shaking. In fact, the wash composition of the present invention is easy to apply and wash off and has an attractive oil-like and transparent or translucent appearance, notwithstanding the fact that the composition is substantially free of oil.

     In a third aspect, the present invention is directed to a method for treating skin with the wash composition of the first or second aspect of the invention. 
     All other aspects of the present invention will more readily become apparent from the description and examples which follow. 
     Skin, as used herein, is meant to include skin on the arms (including underarms), face, feet, neck, chest, hands, legs, buttocks and scalp (including hair). High polyol containing wash composition as used herein is synonymous with “Wash Composition” and “High” means 30% or more by weight polyol in the wash composition. Shaking or agitation includes composition movement and vibration and particularly of the type associated with manufacturing, filling, shipping and the like. The wash composition of the present invention is transparent or translucent and the composition is isotropic. Substantially free of oil means no more than 2.0% by weight oil in the wash composition, and preferably no more than 1.0%, and most preferably, from 0.001 to no more than 0.5% by weight oil based on total weight of the wash composition. In an embodiment of the invention, the wash composition has no (0.0% by weight) oil. Air pockets, 
     as used herein, means suspended air or air vacuoles or particles suspended in the isotropic wash composition of this invention. Such air pockets are visible and known to com-monly have a diameter from 8 to 100 microns, more often, from 10 to 90 microns, and even more often, from
 
10 to 75 microns. Substantially free of air pockets means after sitting at rest for 3 to 7 days, and preferably, from over 24 to under 72 hours, and most preferably, from 12 to 24 hours the wash composition of the present invention, when visually inspected, is at least 90% free of air pockets, and preferably, at least 95% free of air pockets, and most preferably, at least 99% free of air pockets, based on volume of composition visually assessed, and even after shaking or agitation as defined herein. For the avoidance of doubt, therefore, if the wash composition is visually assessed to be 95% free of air pockets, this means the composition at rest has 95% of its volume free from any visibly suspended air. Oil-like appearance means the wash composition has the appearance of an oil-based product, like a product comprising vitamin E oil notwithstanding the fact that the product is substantially free of oil. The wash composition of the present invention is suitable to be a shampoo, make-up wash, facial wash or personal care liquid body wash. Preferably, the wash composition of the present invention is a body wash that is ready for topical application and to be wiped or washed off, and preferably, washed off, with water. The wash composition may, optionally, comprise medicinal or therapeutic agents, but preferably, is a wash which is a cosmetic and nontherapeutic wash. In an embodiment of the invention, the wash composition is a personal wash composition especially suited for use on babies. As hereinafter described, the wash composition of the present invention may optionally comprise skin benefit ingredients added thereto such as vitamins and/or derivatives thereof, resorcinols, retinoic acid precursors, colorants, moisturizers, sunscreens, mixtures thereof or the like. The skin benefit ingredi-ents (or agents) may be water or oil soluble. If used, oil soluble skin benefit agents typically make up to 1.0% by weight of the wash composition whereby watersoluble skin benefit agents, when used, typically make up to 10% by weight of the wash composition. The wash composition typically has a pH from 4.8 to 7.5, and preferably, 5 to 7.5, and most preferably, 6.0 to 7.5. In an embodiment of the invention, the pH of the wash composition can be 6.3 to 7.2, including all ranges subsumed therein. Viscosity, unless noted otherwise, is taken with a Discovery HR-2 Rheometer using sand blasted plates having a 1000 micron gap and a first shear rate S A  of 0.1 s −1  for a first viscosity V A  and a second shear rate S B  of 10 s −1  for a second viscosity V B , both at 25° C. and 20 second intervals. Slope as used herein is defined as [Log(V B )−Log(V A )]/[Log(S B )— Log(S A )]. Viscosity is reported in Pascal seconds (1 Pascal second=1000 centipoise (cps)). Stable, as used herein, means no discoloration or phase separation of the wash composition after being stored for at least one (1) month at 45° C., preferably from 2 to 4 months at 45° C. The term comprising is meant to encompass the terms consisting essentially of and consisting of. For the avoidance of doubt, and for illustration, the composition of this invention comprising surfactant, water and polyol is meant to include a composition consisting essentially of the same and a composition consisting of the same.
 
     Except in the operating comparative examples, or where otherwise explicitly indicated, all numbers in this description indicating amounts or ratios of materials or conditions and/or physical properties of materials and/or use are to be understood as modified by the word “about”. All ranges defined herein are meant to include all ranges subsumed therein unless otherwise stated. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION

     As to the zwitterionic surfactants that may be employed in the wash compositions of the present invention, such surfactants include at least one acid group. Such an acid group may be a carboxylic or a sulphonic acid group. They often include quaternary nitrogen, and therefore, can be quaternary amino acids. They should generally include an alkyl or alkenyl group of 7 to 18 carbon atoms generally comply with an overall structural formula: 
     R 6 —[—C(O)—NH(CH 2 ) q —] r —N + —(R 7 —)(R 8 )A-B where R 7  is alkyl or alkenyl of 7 to 18 carbon atoms; R 7  and R 8  are each independently alkyl, hydroxyalkyl or carboxyalkyl of 1 to 3 carbon atoms; q is 2 to 4; r is 0 to 1; A is alkylene of 1 to 3 carbon atoms optionally substituted with hydroxyl, and B is —CO 2 — or —SO 3 —.

       or 
       R 6 —CONH(CH 2 ) u —N + —(R 7 )(R 8 )(CH 2 ) 3 SO 3   − 
 
     where u is 2 or 3, or variants of these in which —(CH 2 ) 3 SO 3   − is replaced by— 
       CH 2 C(OH)(H)CH 2 SO 3   − . 
     In these formulae, R 6 , R 7  and R 8  are as previously defined.

     Even other useful cationic surfactants suitable for optional use include quaternized hydrol-ysates of silk, wheat, and keratin proteins, and it is within the scope of the invention to use mixtures of the aforementioned cationic surfactants. 
     If used, cationic surfactants will make up no more than 1.0% by weight of the wash composition. When present, they typically make up from 0.01 to 0.7%, and more typically, from 0.1 to 0.5% by weight of the wash composition, including all ranges subsumed therein. 
     In an embodiment of this invention, the wash composition of this invention will be substantially free of polymeric quaternary ammonium compounds (including salts of the same). In another embodiment, the wash composition will comprise less than 0.1% by weight polymeric quaternary ammonium compounds. In yet another embodiment, the wash composition comprises less than 0.01% by weight polymeric quaternary ammonium compounds. In even another embodiment, the wash composition is free of polymeric quaternary ammonium compounds (i.e., 0.0%). 
     Water typically makes up from 5 to 70%, and preferably, from 20 to 60%, and most preferably, from 25 to 55% by weight of the wash composition, including all ranges subsumed therein. 
     Adjusters suitable to modify/buffer the pH may be used. Such pH adjusters include triethylamine, NaOH, KOH, H 2 SO 4 , HCl, C 6  H 8  O 7  (i.e., citric acid) or mixtures thereof. The pH adjusters are added at amounts to yield the desired final pH. The pH values may be assessed with commercial instrumentation such as a pH meter made commercially available from Thermo Scientific®. 
     Optional skin benefit agents suitable for use in the wash composition of this invention are limited only to the extent that they are capable of being topically applied, and suitable to dissolve in the wash composition at the desired pH. 
     Illustrative examples of the benefit agents suitable to include in the water portion of the wash composition are acids, like amino acids, such as arginine, valine or histidine. Additional water soluble benefit agents suitable for use include vitamin B 2 , niacinamide (vitamin B 3 ), vitamin B 6 , vitamin C, mixtures thereof or the like. Water soluble derivatives of such vitamins may also be employed. For instance, vitamin C derivatives such as ascorbyl tetraisopalmitate, magnesium ascorbyl phosphate and ascorbyl glycoside may be used alone or in combination with each other. Other water soluble benefit agents suitable for use include 4-ethyl resorcinol, extracts like sage, aloe vera, green tea, grapeseed, thyme, chamomile, yarrow, cucumber, liquorice, rosemary extract or mixtures thereof. Water soluble sunscreens like ensulizole may also be used. Total amount of optional water soluble benefit agents (including mixtures) when present in the invention may range from 0.0 to 10%, preferably from 0.001 to 8%, and most preferably, from 0.01 to 6% by weight, based on total weight of the wash composition and including all ranges subsumed therein. 
     It is also within the scope of the present invention to optionally include oil (i.e., non-water) soluble benefit agents. The wash composition, again, is substantially free of oil, and preferably, has no oil (0.0%) where oil is not meant to include any oil added from a fragrance. Thus, oil soluble actives or benefit agents are solubilized in the surfactants used. The only limitation with respect to such oil soluble benefit agents are that the same are suitable to provide a benefit when topically applied. 
     Illustrative examples of the types of oil soluble benefit agents that may optionally be used in the compositions of this invention include components like stearic acid, vitamins like Vitamin A, D, E and K (and their oil soluble derivatives), sunscreens like ethylhexylmethoxycinnamate, bis-ethyl hexyloxyphenol methoxyphenol triazine, 2-ethylhexyl-2-cyano-3,3-diphenyl-2-propanoic acid, drometrizole trisiloxane, 3,3,5-trimethyl cyclohexyl 2-hydroxybenzoate, 2-ethylhexyl-2hydroxybenzoate or mixtures thereof.

Also, 5-substituted resorcinols like 4-cyclohexyl-5methylbenzene-1,3-diol, 4-isopropyl-5-methylbenzene-1,3-diol, mixtures thereof or the like may be used. The 5-substituted resorcinols, and their synthesis are described in com-monly assigned U.S. Published Patent Application No. 2016/0000669A1. 
     Even other oil soluble actives suitable for use include omega-3 fatty acids, omega-6 fatty acids, climbazole, farnesol, ursolic acid, myristic acid, geranyl geraniol, oleyl betaine, cocoyl hydroxyethyl imidazoline, hexanoyl sphingosine, 12-hydroxystearic acid, petroselinic acid, conjugated linoleic acid, terpineol, thymol mixtures thereof or the like. 
     In an embodiment of the invention, the optional oil soluble benefit agent used is a retinoic acid precursor. In one embodiment of the invention, the retinoic acid precursor is retinol, retinal, retinyl propionate, retinyl palmitate, retinyl acetate or a mixture thereof. Retinyl propionate, retinyl palmitate and mixtures thereof are typically preferred. 
     Still another retinoic acid precursor suitable for use is hydroxyanasatil retinoate made commercially available under the name Retextra® as supplied by Molecular Design International. The same may be used in a mixture with the oil soluble actives described herein. 
     When optional oil soluble active is used in the compositions of the invention, such active typically makes up from 0.0 to 0.75%, and preferably, from 0.001 to 5%, and most prefera-bly, from 0.05 to 0.35% by weight of the wash composition. In yet another embodiment, oil makes up from 0.1 to 0.5% by weight of the total weight of the wash composition, including all ranges subsumed therein and excluding any oil provided from a fragrance. 
     Conventional preservatives can desirably be incorporated into the wash composition to protect against the growth of potentially harmful microorganisms, in addition to the use of sodium benzoate with glyceryl monoester as previously described. Cosmetic chemists are familiar with appropriate preservatives and routinely choose them to satisfy the preservative challenge test and to provide product stability. Suitable traditional preservatives for use include hydantoin derivatives and propionate salts. Particularly preferred preserve-tives are iodopropynyl butyl carbamate, phenoxyethanol, 1,2-octanediol, hydroxyacetophenone, ethylhexylglycerine, hexylene glycol, methyl paraben, propyl paraben, imidazoli-dinyl urea, sodium dehydroacetate, dimethyl-dimethyl (DMDM) hydantoin and benzyl alcohol and mixtures thereof. Other preservatives suitable for use include sodium dehydroacetate, chlorophenesin and decylene glycol. The preservatives should be selected having re-gard for the use of the composition and possible incompatibilities between the preservatives and other ingredients in the emulsion. Preservatives are preferably employed in amounts ranging from 0.01% to 2.0% by weight of the total weight of the wash composition, including all ranges subsumed therein. Also preferred is a preservative system with hydroxyacetophenone alone or in a mixture with other preservatives. 
     Fragrances, fixatives, chelators (like EDTA) and exfoliants may optionally be included in the wash composition of the present invention. Each of these substances may range from about 0.03 to about 5%, preferably between 0.1 and 3% by weight of the total weight of the wash composition, including all ranges subsumed therein. To the extent the exfoliants are used, those selected should be of small enough particle size so that they do not impede the performance of any packaging used to dispense the compositions of this invention. 
     Conventional emulsifiers having an HLB of greater than 8 may optionally be used. Illustrative examples include Tween, 40, 60, 80, polysorbate 20 and mixtures thereof. Typically, emulsifiers for water continuous systems make up from 0.03 to 1.5% by weight of the wash composition. 
     As to the wash composition of the present invention, the same typically has from 1 to 32%, and preferably, from 2 to 20%, and most preferably, from 3 to 12% by weight total surfactant, based on total weight of the wash composition and including all ranges subsumed therein. In an embodiment of the invention, the wash composition comprises from 7 to 11% by weight total surfactant based on total weight of the wash composition and including all ranges subsumed therein. 
     When making wash composition of the present invention, the desired ingredients may be mixed with conventional apparatus under moderate shear and atmospheric conditions, with temperature being from 30 to 85° C. whereby shear continues until a homogeneous product is recovered. 
     The packaging for the wash composition typically is not limited as long as composition can be dispensed. In an embodiment on the invention, the wash composition is sold in a pouch, bottle, jar, tube or canister. The packaging preferably allows for infinite numbers of refilling to invariably reduce plastic waste in the environment. 
     The Examples are provided to facilitate an understanding of the invention. They are not intended to limit the scope of the claims. 
     All Samples in the Examples were prepared by mixing the ingredients with moderate shear and 
     with temperature being about 80° C. and pressure being atmospheric.

     The viscosities and slopes of the wash compositions of Samples 1-6 reflect that the same were not prepared consistent with the present invention. Moreover, the compositions were not translucent or transparent and had very visible signs of air pockets after production and filling into glass jars. The compositions were heavily aerated and after about 24 hours the air did not dissipate. The compositions of these Samples were presented to skilled panelist and none concluded the samples had an oil-like appearance.

     The compositions made in Samples 7 to 15 had viscosities and slopes to reflect they were prepared consistent with the present invention. 
     Subsequent to preparing, the wash compositions of the Samples were transparent and substantially free (after visual inspection) of air pockets. 
     After moving the composition and filling glass jars, the wash compositions had visual signs of air pockets that almost completely dissipated in about 24 hours. Moreover, skilled pan-elists observed the compositions of Samples 7 to 15 and all concluded the compositions had an oil-like appearance, notwithstanding the fact that they were not formulated to con-tain oil.
