Title: Longwearing composition for keratinous fiber

Description:
FIELD 
     Inventive subject matter disclosed herein relates to mascara formulation embodiments. 
     BACKGROUND 
     Conventional oil-in-water mascara formulations typically include high concentrations of non-emulsifying waxes and low concentrations of adhesive, long wearing polymers to create a lash thickening, volumizing mascara. However, these mascara formulations typically do not wear well. They tend to flake off shortly after application. 
     Also, oil-in-water mascaras with a high load of polymers added for long wear “dilute” the bulk sufficiently to negatively influence and inhibit the volumizing effect of the mascara on the lashes. Usually, with high levels of film forming agent, the mascara bulk has a less creamy texture, thus reducing the building effect on the lashes, imparting a low volumizing effect. Additionally, conventional mascara formulations feel dry, hard and brittle and tend to look dull. To compensate for the low volumizing effect, a high load of waxes is typically employed to add structure and body to the mascara formulation and to provide a desired volume. With increased concentrations of waxes, however, higher concentrations of emulsifier are needed, all of which negatively impact long-lastingness of the mascara film. 
     SUMMARY 
     Inventive embodiments disclosed herein include an oil-in-water mascara formulation that includes non-emulsifying wax(es) in a concentration of 0.10 to 12.00 percent by weight; at least one viscosity modifier; and at least one non-wax grafted polymer and at least one wax grafted polymer with a combined concentration of 0.10 percent to 50.00 percent. 
     Inventive embodiments disclosed herein include a particular mascara formulation embodiment. 
     The formulation embodiment includes the following ingredients:

     The particular mascara formulation and other inventive embodiments disclosed herein include an oil-in-water mascara formulation that includes a non-emulsifying wax in a concentration of 0.10 to 12.00 percent by weight; at least one viscosity modifier; and at least one non-wax grafted polymer and at least one wax grafted polymer with a combined concentration of 0,1 percent to 50 percent. While the ammonium acrylates copolymer formulation concentration is listed as 30.00% by weight and the styrene/acrylates copolymer formulation is listed as 20.00% by weight above, it is understood that other concentration ranges are suitable so long as the total concentration of these two formulations is 50% of the mascara formulation. 
     These ingredients form a strong, yet volumizing film, which eliminates the need for very high concentrations of waxes in the formula. Mascara formulation embodiments also include 12% or less of non-emulsifying wax in an oil phase, about 50% less than what is used conventionally in high volume washable mascara formulations. This combination of ingredients work in synergy, to form a durable and long lasting, yet high volumizing film, which is easily removed with soap and water or warm water alone. Some embodiments are easily removed with soap and water. Other embodiments are easily removed with warm water alone. 
     Inventive mascara embodiments directly solve a problem of making a long lasting mascara that is also easily removable with soap and water or with warm water alone, without soap.

     While hectorite and hydroxymethylcellulose are disclosed as aqueous viscosity modifiers, it is believed that other aqueous viscosity modifiers may be usable in formulations disclosed herein, either singly or in combination. 
     While stearic acid and cetyl alcohol are disclosed herein as emulsifiers, it is believed that other emulsifiers including hydrogenated palm glycerides and potassium cetyl phosphate, and polysorbate 20, and other conventional emulsifiers are also suitable emulsifiers used singly or in combination. 
     While black iron oxide is disclosed herein, it is believed that other pigments are usable in formulation embodiments disclosed herein. Specific black iron oxide formulations employed include Black Iron Oxide C33-5000 and black iron oxide C33-6000, both manufactured by Sun Chemical. 
     While aminomethyl propandiol is disclosed herein, it is believed that other conventional pH adjusters and buffers are usable for use herein. 
     For some embodiments, the concentration of ingredients in Phase exceeds 50% by weight. 
     The term, “QS” used to describe the concentration of water refers to the amount of water added to take the formulation to 100% by weight. 
     Inventive embodiments disclosed herein additionally include film formers. In the formulation embodiment disclosed herein, the polymer combination includes at least one polyolefin grafted film former and one or more acrylates type film former, in a combined concentration of 0.1-50%. 
     In the exemplary formulation embodiment disclosed herein, a non-emulsifying wax is Carnauba wax, listed in Stage 1. Carnauba wax is also known as Carnauba Wax Prime, Yellow 2442, manufactured by Kahl GmbH &amp;Co. Another wax is the 8104 Kahl White Beeswax, manufactured by Kahl GmbH &amp; Co. The stearic acid and cetyl alcohol (Lanette 16) are emulsifiers that enable stage 1 ingredients to blend with aqueous based ingredients in Stage 2. VP/Eicosene copolymer, sold as Unimer U-15, manufactured by Induchem USA, is alkylated vinyl pyrolidone copolymer. In the formulation embodiments disclosed herein, the alkylated vinyl pyrolidone acts as a film former and pigment dispersing agent. 
     Stage 2 is an aqueous stage with water, a powdered smectite clay, hectorite, sold as Bentone EW, manufactured by Elementis Specialties; hydroxyethyl cellulose, sold as NATROSOL 250 HR PC, manufactured by Ashland Inc. Stage 2 also includes propylene glycol and water. 
     The mascara pigments, black iron oxide, are ingredients in Stage 4 of the formulation. 
     Stage 5 includes the aminomethyl propanediol, sold as MPD Ultra-PC, that acts to neutralize acids in the formulation to form salts and water. 
     The phenoxyethanol of Stage 7 is a germicide. D-Panthenol 75L, manufactured by Coptis, is a moisturizer. Vitamin E is an anti-oxidant. 
     For some embodiments, other waxes are used in conjunction with non-emulsifying waxes. The low concentrations of non-emulsifying waxes provide a flexible formulation, while also adding to the building characteristics of the formula by providing structure and slip necessary to aid in volumizing benefit of mascara. 
     Volumizing mascara embodiments disclosed herein provide pristine wear and easy removal from eyelashes with soap and water for some embodiments or warm water alone as described herein. Formulation embodiments disclosed herein provide an optimized combination of film formers and waxes producing a flexible film that instantly build volume and length and stays put through humid conditions while being easy to remove. 
     The combination of hectorite, the Bentone smectite clay, and hydroxyethylcellulose act as an aqueous viscosity modifying agent, which in turn, facilitates deposition of the formulation embodiments onto lashes. 
     Emulsifiers are used in both the oil and water phases to keep the two phases together and to prevent phase separation by forming a tight, stable oil-in-water emulsion. 
     The combination of two non-wax grafted and wax grafted polymers at a combined concentration of 0.1%-50% aid to form a durable, flexible, and volumizing film that provides additional structure to the formulation as well. Examples of such polymers are formulations that include ethylene/acrylate acid copolymer and styrene/acrylates copolymer and water and phenoxyethanol and caprylyl glycol and sodium laureth-12 sulfate and C(11-15) pareth-7 and C(11-5) pareth-40, with a formulation of ammonium acrylates copolymer, water, alcohol, denatured, disodium deceth-6 sulfosuccinate, laureth-30 and sodium. 
     By using varying concentration ratios of both a formulation that includes ethylene/acrylate acid copolymer and styrene/acrylates copolymer and water and phenoxyethanol and caprylyl glycol and sodium laureth-12 sulfate and C(11-15) pareth-7 and C(11-5) pareth-40, and a formulation of ammonium acrylates copolymer, water, alcohol, denatured, disodium deceth-6 sulfosuccinate, laureth-30 and sodium of Stage 8, in combination with 0.10-12.00% wax(es), and aqueous viscosity modifying agents, the mascara features of longevity on a lash and volumizing on the lash are achieved. The volumizing mascara formula employs a high concentration of polymer and low concentration of waxes, contrary to known oil in water mascara formulations. 
     In the embodiments presented herein, the formulation of ammonium acrylates copolymer, water, alcohol, denatured, disodium deceth-6 sulfosuccinate, laureth-30 and sodium has a concentration of 25.00% of the mascara formulation. The formulation that includes ethylene/acrylate acid copolymer and styrene/acrylates copolymer and water and phenoxyethanol and caprylyl glycol and sodium laureth-12 sulfate and C(11-15) pareth-7 and C(11-5) pareth-40, has a concentration of 15.00% of the mascara formulation. The formulation of ammonium acrylates copolymer, water, alcohol, denatured, disodium deceth-6 sulfosuccinate, laureth-30 and sodium is an ammonium acrylates copolymer manufactured by Worlee of Hamburg Germany under the name, Micromer C60/42. The formulation that includes ethylene/acrylate acid copolymer and styrene/acrylates copolymer and water and phenoxyethanol and caprylyl glycol and sodium laureth-12 sulfate and C(11-15) pareth-7 and C(11-5) pareth-40, is manufactured by Interpolymer under the name, Syntran PC 5288, and is formed by grafting an amorphous functional acrylic polymer section onto a crystalline polyethylene backbone.
