Definitions

• the present invention pertains to detergent compositions, and more particularly to liquid detergent composi tions especially adapted: forthe cleansing of hard surfaces.
• Liquid detergent compositions for the cleansing of hard surfaces should be uniform in order to achieve optimum cleaning and customer acceptance.
• cleansers are formulated from an ethanolamide nonionic detergent and an inorganic phosphate in an aqueous medium, the resulting formulations are not uniform liquids, but rather they are heterogeneous liquids or'gels or solids. If high molecular weight soaps, i.e., alkali metal salts of fatty acids having at least 16 carbon atoms, are added to such formulations in an attempt to make them uniform liquids, the resulting formulations are still not uniform liquids.
• Examples 1 through 4 show detergent formulations containing an inorganic phosphate and an ethanolamide nonionic detergent in water and Examples 5 through 8 show such compositions to which a high molecular weight soap has been added. All of the formulations of Examples 1 through 8 were heterogeneous" liquids or gels or solids at room temperature of about-80 F. The amounts of the components are expressed in percent by weight of the compositions.
• hard surfaceliquidcleansers which are substantially clear and uniform and have a viscosity which can be varied from about 3 centipoises to about 10,000 centipoises.
• compositions of the invention are substantially clear uniform liquid detergent compositions consisting essentially of anaqueous solution of an inorganic phosphate, an ethanolamide nonionic detergent, and at least one low molecular weight soap or at least one low molecular weight soap plus at least one high molecular weight soap.
• compositions of the invention because the resulting compositions are heterogeneous liquids or gels or solids. at room temperature: lauric monoethanolamide, myristic monoethanolamide, tallow monoethanolamide, stearic diethanolamide and lauric isopropanolamide.
• the low molecular weight soap component acts as a hydrotrope to solubilize the ethanolamide nonionic detergent in the presence of the, inorganic phosphate and to solubilize any high molecular weight soap present in the compositions.
• the low molecular weight soap component is a water-soluble alkali metal fatty acid soap One or more of.
• low molecular weight soaps having from 6 to 14 carbon atoms.
• low molecular weight soaps may be present in the compositions.
• Typical useful low molecular weight soaps include sodium and potassium caproate, caprylate, caprate, laurate, and myristate.
• the remaining essential component of the compositions' is the solvent medium, namely water.
• the amounts of the components present in the compositions will vary depending upon the specific phosphate, ethanolamide nonionic detergent, and low molecular weight soap employed in formulating the compositions. In general, however, as the amount of phosphate is increased, the amount of low molecular weight soap must also be increased except for the shorter chain length low molecular weight soaps. Also as a general rule the amount of low molecular weight soap and ethanolamide nonionic detergent is increased when shorter chain length.
• low molecular weight soaps are used.
• a further general principle in determining the amounts of the components present in the compositions of the invention is that as the amount of phosphate is increased, the longer chain length low molecular weight soaps become less effective as hydrotropes or solubilizing agents.
• the amount of phosphate is from about 5% to about 20% by weight, andpreferably about 10% by weight, of the composition.
• the amount of low molecular weight soap' isfrom about 1% to about 15% by weight of the composition.
• the amount of caprylic monoethanolamide or capric monoethanolamide is from about 1.5% to about 7% by weight of the composition
• the amount of oleic monoethanolamide is from about 1.5% to about 13% by weight of the composition
• the amount of caprylic diethanolamide, capric diethanolamide, lauric diethanolamide, myristic diethanolamide, palmitic diethanolamide or oleic diethanolamide is from about 1.5% to about 16% by weight of the composition.
• the above amounts of phosphate, soap and ethanolamide are further adjusted to maintain. the composition substantially clear and uniform.
• liquid detergent compositions of the invention will have a viscosity as low as about 3 or 4 centipoises.
• Such compositions are thin liquids which have the advantage of spreading rapidly in use.
• Such thin liquids however, have some disadvantages in that they drip from the spoutof the container on pouring and give the false impression of being watery and weak. While.
• the high molecular weight soap increases the viscosity of the compositions and-con tributes of the detergency and grease emulsification-propertiesthereof. They also serve to provide the proper suds desirable in a hard surface cleanser.
• the high molecular weight soap component is a watersoluhle alkali metal fatty acid soap having at least r16 carbon atoms and'in general from 16'to 18 carbon atoms. Typical examples thereof are sodium and potassium palmitate, stearate and ole'aten If desired, one or 'more of such .highmolecular weight soaps can beused.
• soaps produced from the naturally occurring mixture of fatty acids present in tallow can be utilized.
• the high molecular weight soap component constitutes a. small amount .of the compositions. In general, theamount is not higher than about 10% by Weightrofthe composition. Usually the amount thereof is not over about 5% by weight. molecular weight soap component is from about 1% to about'4% byweight. l
• compositions of the invention can also be present in the compositions of the invention.
• compatible adjuvants can also be present in the compositions of the invention. Typical of such materials are perfumes, dyes, preservatives, wetting agents, 5 30 storage stabilizers, and auxiliary hydrotropes.
• compositions are-readily prepared by merely mix-. ing the components thereoftogether.

• Example 61 demonstrates that the compositions can contain various compatible adjuvants.
