(9) Process and Composition:

(10) Provide herein is a gellant technology optionally in combination with colorants and sunscreens to deliver a pigmented cosmetic makeup composition with a novel and unique texture, finish and end benefits.

(11) Provided herein is a gel cream colorant composition with thickening polymer, hydrating and protective properties. The composition comprises an anionic acrylate/beheneth-25 methacrylate copolymer and at least about 40% by weight water. The composition can also comprise any combination of colorant(s) and sunscreen filter(s), powder(s), film former(s), neutralizing agent(s), humectant(s), preservative(s), emollient(s), gellants(s), bioactive(s), chelating agent and/or fragrance(s). This composition delivers a “jelly” texture, lightness and care more associated with non-pigmented skin care products while also delivering the color, wear and finish associated with pigmented cosmetic make up products.

(12) The cosmetic composition of the claimed inventive embodiments is an emulsion that includes two separate gelled phases. One embodiment for making the cosmetic composition includes preparing an aqueous solution that includes a strong gelling and suspending agent, such as xanthan gum, in a concentration within a range of 0.1 to 5 percent by weight, such as a range of 3 to 5 percent by weight. Other gums, such as carboxycellulose gums are suitable for use, within the 0.1 to 5 percent concentration range, such as a range of 3 to 5 percent by weight. Once the aqueous solution with the gellant(s) is prepared, color pigments are added to the aqueous solution. Pigments include those conventionally known in the art, within 0.1-25% total powder concentration. Humectant(s), chelating agent and additional powder(s) may be included in this phase.

(13) Next, in one embodiment, a gellant emulsifier, Net-WRS is added to the formulation. Net-WRS is manufactured by Barnet Products Corp. of Englewood Cliffs. N.J. The Net-WRS is a mixture of sorbeth-30, tetraisostearate, sorbitan sesquiisostearate, PPG-8 Deceth-20, acrylates/beheneth-25 methacrylate copolymer, dipropylene glycol and water. This composition for cosmetic use is a thickening polymeric gel with lipophilic and hydrophilic portions that form a matrix.

(14) An oil phase is prepared with one or more oils conventionally used in foundation cosmetics, one or more emollients including sunscreen filters, and an oil-based gellant, such as Bois Gel, manufactured by Barnet Products Corp. of Englewood Cliffs, N.J. The Bois Gel includes glyceryl myristate, glyceryl palmitate, glyceryl stearate, glyceryl ricinoleate, glyceryl eicosadioate and dextrin palmitate. Other oil based gellants may be used such as, but not limited to, self-emulsifying waxes, oil thickeners, clays, silicas and elastomers.

(15) The oil phase is blended with the aqueous phase then a neutralizer is used to set the desired pH for jellification of the polymeric gel emulsifiers. Film former(s), preservative(s), bioactive(s) and fragrance may be included at this point. The neutralizer can be added at any point of the formation of the water phase or final emulsion.

(16) The addition of the oil phase and aqueous phases will create a final embodiment, comprising a mixture of polymer emulsifier and polyethylene emulsifiers with any combination of water dispersible colorants and powders between 0.1-25%, physical and chemical sunscreen filters between 2-30%, water between 30-90%, including 40-80%, film forming polymers between 0.5-5%, neutralizing agent between 0.1-2.5%, humectants, preservatives, emollients, gellants, bioactives, chelating agent and fragrance.

(17) The water content of the composition can be as low as 30% by weight and may be as high as 90%, including for example 40% to 80%. This insures the hydration, lightness and freshness.

(18) Suitable aqueous gellants include, but are not limited to, acrylate copolymer, xanthum gum, biosaccharide gum, including all aqueous gellants listed in the CTFA Vol. 6, and the mixtures thereof. This provides proper suspending and gelling of aqueous phase.

(19) Suitable humectants include but are not limited to, glycerin, propylene glycol, sodium PCA, galactoarabinan, dipropylene glycol, biosaccharide gum, butylene glycol, pentylene glycol including all humnectants listed in the CTFA Vol. 6, and the mixtures thereof. These contribute to the moisturizing benefits of the composition.

(20) Colorants suitable for this gel product include, but are not limited to, titanium dioxide, iron oxide, mica, dye, organic colorants and pearls with and without coating or surface treatment. These provide the color payoff.

(21) In one embodiment, the bioactives/antioxidants used in the cosmetic composition include, but are not limited to, retinyl palmitate, tocopheryl acetate, ascorbyl palmitate, and other forms of antioxidants. These provide antioxidant activity and other benefits to the skin.

(22) The cosmetic composition of the present invention includes at least one film forming polymer with the objective to increase the wear of the colorants on the skin. According to the invention, the film forming polymer used in the composition includes, but is not limited to polyurethane-14, acrylates copolymer, galactoarabinan, silicone resin, and biosaccharide gum. This is to enhance the wear of the product.

(23) In one embodiment, to avoid the negative effects in the presence of the metallic ions in the composition of the invention, disodium EDTA is used as a sequestering or chelating agent.

(24) Furthermore, in one embodiment, to make the cosmetic composition more presentable, spherical and absorbent powders, including but not limited to, opacifiers and sensory modifiers such as barium sulfate, bismuth oxychloride, boron nitride, and/or kaolin and polymethyl methacrylate including all spherical and absorbent powders listed in the CTFA Vol. 6, may be used in the composition.

(25) In at least one embodiment, the neutralizing agent includes, but is not limited to, sodium hydroxide, citric acid, triethanolamine or mixtures thereof.

(26) Suitable oil based gellants includes but are not limited to, dextrin palmitate, tribehenin, trihydroxystearin, myristic/palmitic/stearic/ricinoleic/eieosanedioic glycerides, polyglyceryl waxes, self-emulsifying waxes, oil thickeners, clays, silica, elastomers, oil absorbent powders.

(27) In one embedment, the composition comprises one or more emollients, such as any suitable ester including, but not limited to, nonvolatile silicone, and/or hydrocarbon fluids. Emollients can also include caprylic/capric triglyceride, dicaprylyl ether, dimethicone, dimethiconol and mixtures thereof. These contribute to the comfort, film forming and finish of the formulation. Sunscreen filters may also be included in the oil phase, such as organic filters and inorganic filters for sunscreen protection.
