Abstract:
A bar soap preparation having enhanced antibacterial and microbial properties, the bar soap consisting of:(A) from about 0.1 weight % to about 95 weight % of at least one anionic surfactant based on the total weight of the preparation; (B) at least one acidifying agent present in an amount sufficient to impart a pH of below 5.0, in aqueous solution the acidifying agent being at least one acidifying agent selected from the group consisting of acetic acid, adipic acid, benzoic acid, citric acid, dehydroacetic acid, erythorbic acid, fumaric acid, glutaric acid, gluconic acid, hyaluronic acid, hydroxyacetic acid, lactic acid, malic acid, sorbic acid, succinic acid, tannic acid, tartaric acid, sulfuric acid, phosphoric acid, nitric acid, hydrochloric acid, sulfamic acid, poly lactic acid or poly lactic-glycolic acid, wherein microbial protection results from reduction of the microbial population; (C) at least one antibacterial agent selected from the group consisting of benzoic acid salts, esters of benzoic acid, sorbic acid salts, esters of sorbic acid, alkyl esters of para hydroxy benzoic acid, chlorohexidine, imidazolidinyl urea, isothiazolin compounds, triclosan, dehydroacetate, o-phenyl phenol, quaternium compounds, boric acid, formaldehyde solution, butylated hydroxyanisole, butylated hydroxy toluene, fatty acids, fatty acid salts and antibacterial peptides; (D) at least one lubricating agent selected from the group consisting of xanthan, arabic, ghatti, carrageenan gums, starch, cellulose, alginic acid, dextrans, starch and cellulose polymers, acrylates, carboxylates, sulfated polymers, polaxomers, and silicone based compounds, wherein the at least one skin conditioning agent is present in an amount present between 0.001% by weight and 5.0% by weight; (E) at least one skin conditioning agent selected from the group consisting of aloe Vera, sea weed extracts, hydrolyzed proteins products, lanolin, lanolin esters, vitamins A, vitamin C, vitamin D, and wherein the at least one skin conditioning agent is present in an amount present between 0.001% by weight and 5.0% by weight; (F) at least one coloring agent selected from the group consisting of which includes natural carmine, chlorophyl, curcumin, annatto, plant based colors, caramel color, and FD&C coloring agents, wherein the coloring agent is present in an amount less than 5.0% by weight; (G) at least one moisturizing agent selected from the group consisting of hyaluromc acid, maize amino acids, soluble collagen, glycerine, sorbitol, silk amino acids, polyethylene glycol, panthenol and gluconate, wherein the moisturizing agent is present in an amount less than 5.0% by weight; (H) at least one binding and anti-cracking agent selected from the group consisting of natural gums, polysaccharides, fatty alcohol, paraffin, lanolin, hydrogenated oils, glycerides, wherein the binding and anti-cracking agent is present in an amount less than 5.0% by weight; (I) at least one thixotropic agent selected from the group consisting of modified gums, and synthetic polymer compounds, wherein the thixotropic agent is present in an amount less than 5.0% by weight; (J) at least one solubilizing agent selected from the group consisting of water, propylene glycol, ethyl alcohol, fatty alcohols, isopropanol, ethyl acetate, wherein the solubilizing agent is present in an amount less than 5.0% by weight; (K) at least one emulsifying agent selected from the group consisting of lecithin, polysorbate 60, polysorbate 65, polysorbate 80, sucrose fatty acid esters and salts of stearyl 2-lactylate, wherein the emulsifying agent is present in an amount less than 5.0% by weight; (L) at least one abrasive agent selected from the group consisting of silica, plant seed coat powders and clays, wherein the abrasive agent is present in an amount less than 5.0% by weight and; (M) at least one antioxidant agent selected from the group consisting of ascorbic acid, vitamin E and flavanoids, wherein the antioxidant agent is present in an amount less than 5.0% by weight.
