• the slurry flows or is pumped into a conventional soap crutcher or any other suitable mixing apparatus such as a ribbon blender.
• the anionic detergent should desirably be added to the crutcher prior to addition of the quaternary compound in order to avoid formation of any significant amount of insoluble, anioniccationic complex.
• the other ingredients are then added in any suitable order and form.
• the cationic quaternary ammonium compound is added, usually as a fine white powder with stirring.
• the resulting slurry should be suificiently fluid at the elevated temperatures to insure adequate mixing and formation of a uniform product, and is subjected to a heat treatment at an elevated temperature such as with the range of about to about 200 F., and usually from about to F.
• the slurry is heated by external means or even by the exothermic heat of reaction of certain ingredients.
• hydratable inorganic salts such as the anhydrous forms of sodium tripolyphosphate and sodium pyrophosphate results in exothermic reactions as hydration occurs. It is desirable generally to add the polyphosphate and/or other builder salt or salts in the final stages of the crutching operation.

• the detergent composition can be transformed into beads, granules, flakes, chips, powders or the like as desired by use of conventional techniques.
• the aqueous slurry In spray-drying the aqueous slurry, it is atomized or forced through spray nozzles into toweers, with small liquid particles discharged from the nozzles becoming solidified and drying as they contact or fall through a stream or vortex of heated air or other inert gas which is at about 600 F.
• the composition is produced thereby in the form of hollow thin-walled spheres or beads having a small residual moisture content usually of about 3 to 15 percent by weight.
• the quaternary compound does not react with the non-soap, anionic detergent to form any insoluble precipitate to any significant extent.

Furthermore, when the final product is dissolved in water, a substantially clear solution is obtained, thereby indicating the substantial absence of insoluble anionic-cationic complex or precipitate.
• a heat-treated detergent composition in particulate formProduct 1 is prepared according to the following approximate formulation:

• the temperature of the crutcher slurry is maintained at 140155 F. for one hour with agitation and there is formed a smooth, pumpable mixture having a total solids content of about 5560 percent. It is then pumped into a spray tower where it is spray-dried with air heated to about 600 Ffto yield a product in the forms of beads.
• the ingredients are mixed in the form of an aqueous slurry in a crutcher for minutes at a temperature 'between and F.
• the resultant slurry of 50-60 percent solids is then pumped into a spray tower where it is spray-dried with air heated to about 550 F. to yield a product in the form of hollow beads.
• EXAMPLE 3 Product 3 was prepared in spray-dried form as described in example.
• Product 3 is satisfactory for use in tumbler-type automatic washing machines, and produced a clear solution at a 0.15 percent concentration in water.
• the cellulose is a commercial detergent grade.
• EXAMPLE 4 In the illustrations included in this example the effect of a water-soluble, higher fatty acid salt in the control of foaming, heavy duty anionic detergent compositions is demonstrated by practical laundering operations in agitator-type (the predominant type) and tumbler-type automatic washing machines. Results obtained demonstrate that the presence of a water-soluble, higher fatty acid salt in the detergent compositions does not have a significant effect on the suds level during the period the clothes are being agitated, but does have a significant effect on the rate at which the foam collapses When the agitation is stopped to empty the wash water prior to the initiation of the rinsing operation. Rapid foam collapse during this latter period is desirable to facilitate rinsing operations and to prevent entrapment or inclusion of solids from the foam in the textile fabrics whence it can cause yellowing and objectionable stiffness in the laundered textiles.
• Foam behaviour was evaluated under dynamic and static conditions in the presence of terry cloth switches containing sebum soil. Testing was carried out using a Tergotometer apparatus. Testing procedure consisted of making up 300 cc. of detergent solution at a predetermined concentration level at 120 C., adding the solution to the T ergotometer along with three 1 /2 inch x 1 inch terry cloth swatches containing 40 mgs. of sebum soil each (120 mgs. total) and agitating the system for five minutes. Dynamic foam volume was measured at the end of the five minute agitation period and the static foam volume was determined at one minute intervals following the agitation period.
• Dynamic foam volume in the presence of swatches containing 120 mgs. of sebum soil was found to be equivalent to the foam volume noted in the practical laundering of 8 pound loads of normally soiled textiles in automatic, tumbler-type washing machines; and with this correlation, it is possible to determine which detergent compositions can be classed as controlled foam products.
• the rate of foam collapse noted under static conditions correlates closely with the observations noted under the foregoing practical laundering conditions following the agitation period in both types of washing machines.
• the sebum soil was a mixture formed of:
• Product B was prepared in much the same manner, except that an aqueous solution of the cationic agent was mixed with the aqueous sulfonate solution prior to addition of the builders.
• Product C was prepared in the same manner as Product B, except that an aqueous sodium cocoate solution was mixed with the aqueous sulfonate and aqueous cationic agent solutions prior to addition of the builders.
• Table I demonstrates that watersoluble, fatty acid salt cooperates with the quaternary compound to provide rapid foam collapse consistent with satisfactory rinsing characteristics; and Table II illustrates that the proportion of quaternary ammonium compound is suitably adjusted with the proportions of the non-soap anionic detergent and the fatty acid salt, to achieve the desired foam volume commensurate with satisfactory performance in the automatic, tumbler-type washing machines.
• EXAMPLE 5 Another effective composition, prepared by the dry blending procedure mentioned in EXAMPLE 4 above, is identified below:
• the resulting productProduct was dissolved in water and the resultant solution was used to wash naturally soiled textiles in an automatic, Westinghouse tumblertype washing machine under normal laundering conditions.
• the foam volume during the washing cycle was approximately four inches and foam collapse was very rapid during the period in which the used wash solution was being removed from the machine.
• the appearance of the laundered textiles indicated the composition possessed excellent heavy duty detergency properties.
• EXAMPLE 6 Another effective composition, prepared by dry blending as in Example 4 above, is as follows:
• the product of this exampleProduct 7- was prepared by the spray drying technique described in Example 1, above. It was evaluated at 0.3% concentration in the Tergotometer test in the presence of 120 mgs. of sebum soil and yielded inch of foam volume under agitated conditions and rapid foam collapse in the absence of agitation.
