Definitions

• This invention relates to detergent compounds of the kind in which silica and alumina are combined with alkali, and to methods of making the same.
• the objects of this invention are to produce a combination of these ingredients which will readily solidify and which will contain a smaller amount of insoluble matter and have a higher melting point than similar compounds heretofore made so that the material will not melt when exposed to summer temperatures; also to provide an improved compound which has superior water softening properties; also to provideaprodnot which will operate successfully with a much smaller quantity of soap than has been heretofore required in cleansing processes; also to devise an improved method of making detergents of this kind; and also to improve detergent compounds in other respects as hereinafter specified.
• a may be so selected as to produce a compound which is completely soluble and which has a melting point of about 126 F. These properties are obviously desirable for an efficient and commercially salable detergent.
• the compound may be made in the manner hereinafter described, care being taken, however, that the proportion of the ingredients is in accordance with the generic formula stated.
• alkali metal salts of weak acids such for example as sodium or potassiumcarbonate or certain other carbonates, phosphates. borates or the like greatly enhances the water softening properties of the detergentcompound and produces a compound of moderate causticity. which is much desired for most purposes.
• the addition of such alkali metal salts does not prevent the solidification of the compound at ordinary temperatures, and effects a great saving in the amount of soap required, since the causticity of the compound reduces the hardness of the water. so that a large amount of soap is saved by the use of this compound.
• the alumina andsilica in the compound have certain collodial properties which prevent the cansticity of the compound from injuring the material on which the compound is used.
• I preferably quickly chill the mass discharged from the kettle, since by rapid chilling of the mass. a better crystallizing action is produced, so that the resulting material can be more easily ground. Any desired quantity ofthese alkali salts may be added tothe compound. about five percent having been found satisfactory.
• alkali metal oxide Na,,O
• saponification durin the process of cleansing so that the a,O) specificed in the formula hereinabove mentioned may if desired, be increased, so lon as the mixture produced will remain soli under ordinary conditions of temperature under which the material is shipped and stored.
• alkali metal salts in the detergent a comparatively small quantity of the emulsifying agent can be used and the compound thus produced will form in water a quantity of soap suds which would under ordinary conditions requirea greater quantity of soap.
• a detergent in a hydrated condition and which is formed of alumina, silica, and alkali metal oxide and havin substantially the formula A1 0 (Si(),,) (l ia,,5) (H O) as representing any number greater than seven.
• a detergent in a hydrated condition formed of one molecular weight of alumina, a: molecular weights of silica and a: minus one molecular weights of alkali metal oxide,
• .r molecular weights of silica and .11 minus one molecular weights of alkali metal oxide, :2 representing any number greater than seven into which has been physically incorporated an alkali metalsalt of a weak acid, together with an emulsifying agent and a further quantity of alkali metal oxide sufiicient to replace the alkali metal oxide which is consumed in the saponification dur-' ing the process of cleansin said quantity being small enough to enab e the detergent to maintain itself in a solid condition at summer temperatures.
• a method of forming a detergent in a hydrated condition consisting of boiling quantities of alumina silicate, silicate of soda and caustic lye to form a compound havin substantially the formula A1 0 (SiO,),(Na,O), ,(H as representing any number greater than seven, quickly chilling the material from a liquid to a semi-plastic condition and then permitting the chilled material to crystallize with an elevation in temperature.
