Definitions

• the present invention relates to novel liquid shampoo compositions having highly desirable properties of mildness, conditioning, cleaning and foaming.
• Each constituent of the present shampoo is known in the prior art as a shampoo ingredient, but heretofore no one has combined the present constituents to formulate a shampoo of the present invention.
• a recently marketed shampoo contained triethnolamine alkyl sulfate, triethanolamine coconut fatty acid soap and coconut ethanolamide, but this shampoo was not as mild as the shampoos of this invention.
• Applicants have discovered that the addition of a polyoxyethylene fatty acid ester to a shampoo of the same or similar components results in a shampoo which is unexpectedly mild and which has a highly desirable lather.
• polyoxyethylene fatty acid ester in a shampoo is not novel, having been disclosed as early as 1953 in A Guide to Cosmetic and Pharmaceutical Formulation With Atlas Products, Atlas Powder Company, 47 (1953).
• polyoxyethylene fatty acid ester when used in shampoos of the present invention, exerts an anti-irritant effect on the other shampoo ingredients. This reduces the irritation potential of the shampoo, resulting in a mild shampoo.
• the addition of polyoxyethylene fatty acid ester also increases the desirability of the lather of the shampoo. Further, these unexpected results are not obtained at the cost of reduced cleaning or conditioning.
• the ratio of polyoxyethylene fatty acid ester to other surfactants is from about 1:1 to about 1:5 and the pH of the solution is from about 7.0 to about 8.4.
• the shampoo is surprisingly mild and produces voluminous rich lather when used on both soiled and unsoiled hair.
• the ratio of (A) to the total of (B), (C) and (D) is from about 1:1 to about 1:5 and the pH of the composition in aqueous solution is from 7.0 to 8.4. It is advantageous to control the pH by the addition of triethanolamine as this comopund also prevents contamination of the solution by bacteria.
• polyoxyethylene fatty acid ester decreases the irritation potential of the other components of the above shampoo and results in a shampoo with increased mildness.
• the polyoxyethylene fatty acid ester apparently acts not only as an anti-irritant, but also acts to incease the desirability of the lather feel.
• the lather of the shampoo of the present invention is preferred for its rich, smooth, creamy qualities.
• Shampoos made in accordance with the present invention combine the qualities of excellent mildness and feel with qualities of excellent cleaning, conditioning of hair, and similar loaded and unloaded foam heights. Similar foam heights means that similar quantities of foam are obtained whether the hair is clean or is heavily soiled.
• the ratio of (A) to the total of (B), (C) and (D) is about 5:18 and the pH of the composition in aqueous solution is from about 7.2 to about 8.0.
• the triethanolamine alkyl sulfate may be replaced by an equivalent amount of sodium alkyl sulfate.
• the ratio of (A) to the total of (B), (C) and (D) is 5 :18 and the pH of the composition in aqueous solution is from about 7.2 to about 8.
• the triethanolamine alkyl sulfate may be replaced by an equivalent amount of sodium ethanolamine alkyl sulfate.
• the use of coconut alkyls and fatty acids not only results in an excellent shampoo, but is also economical since they are commercially available.
• a shampoo made in accordance with the present invention can, of course, contain other common shampoo ingredients, for example, a thickening agent, an antioxidant, ancl/or a perfume.
• Triethanolamine alkyl (coconut middle cut sulfate 10.00 Polyoxyethylene (20) sorbitan monolaurate 5.00 Triethanolamine 4.00 Coconut 2 fatty acid 3.00 Coconut 2 monoethanolamide 2.00
• a coconut middle cut consists essentially of about 67% Cu; about 25% C11. and about 8% C16.
• a first shampoo was made as in Example I and was compared to a second shampoo made without polyoxyethylene (20) sorbitan monolaurate but otherwise containing all of the components of Example I.
• Four twoinch square patches of gauze were soaked in the first shampoo and four were soaked in the second shampoo.
• the patches were applied for 24 hours to the upper arms of four human subjects.
• Each subject was exposed to one first shampoo patch and one second shampoo patch. At the end of 24 hours, the patches were removed; and the subjects were graded then and graded again 24 hours later. No irritation was observed under any of the Example I patches while mild irritation was observed under every second shampoo patch by the time of the second grading.
• a mild shampoo consisting essentially of:
• (C) from about 1% to about 10% of triethanolamine coconut fatty acid soap wherein said fatty acid contains from about 10 to about 18 carbon atoms;
• a mild shampoo as recited in claim 6 consisting essentially of from about 4% to about 15% of polyoxyethylene sorbitan fatty acid ester; from about 5% to about of triethanolamine alkyl sulfate; from about 2% to about 5% of triethanolamine coconut fatty acid soap; and from about 2% to about 5% of fatty acid ethanolamide.
• a mild shampoo as recited in claim 1 consisting essentially of about 10% of triethanolamine alkyl sulfate; about 5% 0f polyoxyethylene sorbitan monolaurate; about 4% of triethanolamine; about 3% of coconut fatty acid; about 2% of coconut monoethanolamide; and the balance, water.
