as to provide a pre - mixed flocculant which is then , in turn , added to the detergent concentrate in a concentration ranging from between 2 to 40 % ( dry basis ), balance alkaline builder and wetting agent . preferably , the flocculant is arranged so as to be present in the soilage in an amount ranging from between 300 ppm and 700 ppm . however , from between about 200 ppm and 2000 ppm may be found useful . in addition , a coagulant aid may be utilized , the coagulant aid being bentonite clay and present in an amount of up to about 5 % by weight . as will be appreciated , the coagulant aid is not required for all applications . the working solutions preferably contain 2 % by weight of the detergent portion . working solutions containing up to about 5 % by weight of detergent may be

______________________________________component content______________________________________polydiallyldimethyl - ammoniumchloride of average molecularweight of about 100 , 000 ( 40 % solids solution ) 20 % ______________________________________ this flocculant was employed in the detergent portion , with the balance of 80 % consisting of the builder and wetting agent . the method of preparing the

hydroxide ( 40 % aqueous solution ) 4 % soda ash ( anhydrous ) 8 % sodium metasilicate 3 % surfactant as in example 1 2 % water 78 % ______________________________________ this detergent concentrate was then added to the flocculant formulation of example 15 . the combined formulation may be used in water in an effective range of working solutions , preferably in a dilution ranging from between about 2 and 10 %. the dirt holding capacity of the working solution has been found to be greater than about 35 times the weight of the polyelectrolyte flocculant present . ______________________________________component content______________________________________sodium tripolyphosphate 5 % potassium hydroxide ( 40 % aqueous solution ) 4 % soda ash ( anhydrous ) 8 % sodium metasilicate 3 % surfactant as in example 2 2 % water 78 % ______________________________________ this detergent concentrate was then added to the flocculant formulation of example 15 . the combined formulation may be used in water in an effective range of working solutions , preferably in a dilution ranging from between about 2 and 10 %. the dirt holding capacity of the working solution has been found to be greater than about 35 times the weight of the polyelectrolyte flocculant present . potassium hydroxide is employed as a source of high alkalinity and when present in the solution , provides a ph buffer ( examples 1 , 3 and 4 ). when acidic soils are contacted by the solution , the ph level is maintained elevated even after exposure to substantial quantities of such soils . one further feature of the potassium hydroxide is its enhancement of the interfacial activity of the wetting agent when employed , this material acting to saponify fatty soils which may be encountered in order to render them more readily soluble . sodium carbonate ( soda ash ) is used as an alkaline builder that offers significant saponification properties as well as certain water softening properties to the formulation . because of its elevated ph in solutions , it functions to neutralize acid soils and reinforce the alkalinity in the formulation . among other alkaline builders and alkalinity agents that may find utility in the present formulations are the following : examples of these in formulations are set forth hereinabove . in the formulations , the alkaline builders are employed as a cleaning agent . their primary function is to neutralize acidic soils present in the surfaces being cleaned . furthermore , these materials normally contribute to the emulsification properties of the detergent . the surfactant is a water soluble type as described in the examples and may be either non - ionic , as indicated , or may be anionic and supplied in acid form . these materials are commercially available and are known for their surfactant properties . the primary function of this component in the solution is to improve the wetting power of the water . improvement of the wetting power permits a more complete and rapid penetration of the alkaline solution into and around the soils , thus reducing the mechanical energy which otherwise would be needed to separate the soil from the surface . the surfactant normally possesses a wide temperature range cloud dispersion point . certain non - ionic surfactants having a narrow range of cloud dispersion points may be suitable provided the working range is limited to the stable range . it has been found that the use of a hydrotrope which is compatible with the wetting agent may increase the cloud dispersion point so as to provide a greater workable range . the surfactants or wetting agents preferably are , as indicated , either non - ionic or acid - based anionic type and also preferably have a cloud dispersion point such that the materials remain stable in solution within the working conditions . for example , cloud dispersion points ranging from between 0 ° and above 100 ° c . may be required . in certain applications , surfactants such as octyl and nonyl phenoxy polyethoxy ethanol may be employed . also , a biodegradable modified ethoxylate may be employed , with the ethoxylate being an intermediate - acid form surfactant reactive in alkaline solutions to form a stable component . in certain formulations having a ph which lies for example at about 10 and below , cationic type wetting agents may be employed . cationic type surfactants are compatible with cationic flocculants such as are employed in the present formulations . except for the intermediate - acid form of surfactant , because of the apparent incompatibility of opposite ionic character between flocculants and surfactants , conventional anionic surfactants are normally not as workable in single package systems containing cationic polyelectrolytes . the wetting agents are , as indicated , preferably non - ionic or acid - based anionic types and preferably have a cloud dispersion point such that the materials remain stable in solution within the working conditions . the flocculant is a polyelectrolyte , preferably a high molecular weight cationic polyelectrolyte which causes soilage to agglomerate rather than disperse . in the formulations , it has been found that the formed flocs will float upon agitation , thus providing a clearer residual floor surface and allowing filtering of the solids from the solution . certain natural occurring materials may also be included in the list of flocculants which may be found useful , these being the natural occurring materials as follows : as has been indicated , the materials are preferably cationic types which are compatible with the alkaline builders and they may be employed in lieu of the flocculant employed in the examples . the precise function or operation of flocculation utilizing a high molecular weight polyelectrolyte , either a natural occurring substance or a synthetic substance , is not fully understood . a variety of theories have been advanced from time to time , each expressing a proposed or theoretical mode of operation . two basic premises appear to exist for most theories , that is , when the polyelectrolyte is highly ionic in nature , it may function by charge neutralization on the charged particles which are in the suspension , thereby permitting them to agglomerate . on the other hand , polyelectrolytes of very high molecular weight may become physically adsorbed on two or more particles per molecule , this adsorption phenomena normally being termed &# 34 ; bridging &# 34 ;. the neutralization of electrical charges on the adsorbed polyelectrolyte molecules then may cause it to coil and to become physically inmeshed with agglomerates of other molecules with similar particle holding characteristics , thus contributing to the flocculation operation . the cationic flocculant agents are normally preferred because of their tendency to raise the flocculant to the top of the layer of solution applied to the surface being treated . anionic type flocculants normally do not possess the tendency toward floatation in the working solutions prepared in accordance with the present invention . it will be appreciated , of course , that compatible anionic flocculants may be employed as effective ingredients for certain working solutions . it will be appreciated that the alkaline builders may preferably consist essentially of the following : combinations of sodium tripolyphosphate with materials selected from the group consisting of sodium sulfate and soda ash ( sodium carbonate ) as well as combinations of these materials . these materials have been found to function well . they are , of course , employed to an extent rendering it possible to elevate the ph to a preferred level of at least about 10 . lower ph solutions may be used successfully , however for most soil conditions , systems of the present invention having the higher ph &# 39 ; s are preferred . included in those alkaline builders set forth hereinabove are the various phosphate substitutes such as nta or certain citrate salts such as sodium citrate or potassium citrate may be successfully utilized . the wetting agents or surfactants which are preferred in the present systems normally are non - ionic alkylated water soluble types . when nonylphenoxypoly ( ethyleneoxy ) ethanol is employed , the composition has between about 8 and 16 mols of ethylene oxide on the chain . it will be appreciated that a biodegradable modified ethoxylate may also be employed , with the biodegradable feature normally requiring that a chain length of approximately 4 to 18 carbon atoms or more be present on the chain . these materials are , of course , widely available commercially . the material selected is normally compatible with anionic , non - ionic or ampholytic electrolytes . as has been indicated , the floatation agent is not a critical component and in certain of the formulations , in particular that of example 1 , no floatation agent is required . one floatation agent which may be successfully employed is sodium alkyl aryl sulfonate , such as , for example , a structure having the following structural formula : ## str1 ## wherein r is an alkyl chain having from between about 11 and 13 carbon atoms . the material may be present in an amount ranging from between about 1 and 10 % by weight of the total weight of alkaline builder , wetting agent and flocculant . this material is commercially available . in certain applications , a coagulation aid such as ferric chloride , alum , fly ash , calcium chloride , ferrous sulfate , bentonite clay , guar gum , polyethyleneoxide may be employed . the flocculating agent is preferably polyadiallyl ammonium chloride , and it is preferred that the material have a molecular weight of about 100 , 000 , with molecular weights of up to 300 , 000 being useful as well . flocculating agents of this type having molecular weights between about 100 , 000 and 300 , 000 are commercially available . this material does not adversely affect solubility of the concentrate and thus solutions can be made without extensive blending times being required . this high molecular weight polyelectrolyte is desirable in the systems discussed above . one class of such polyelectrolytes which may be found useful in the formulations of the present invention are disclosed in u . s . pat . no . 3 , 288 , 770 dated nov . 29 , 1966 . generally speaking , the polyelectrolytes which are most effective are those which are capable of increasing the size of the various agglomerates of colloidal particles as well as other entrained solids which are present in the scrubbing solution on the surface being treated in order that they may be easily removed or otherwise extracted from the solution so as to leave a clarified film with most of the soilage particles removed therefrom . these individual agglomerates or flocs must have sufficient mechanical strength so that they will not be broken up or otherwise re - dispersed before ultimate separation from the solution . furthermore , they should be sufficiently large in size so as to be easily separated by conventional filtration techniques . furthermore , the unspent polyelectrolyte preferably has the characteristic of remaining in solution after removal of the agglomerates , so that it may be effectively utilized on subsequent recycling of the solution . in order to provide ranges for formulations either in solution or dry form , which may be employed , the following table is given : table i______________________________________component content______________________________________an alkaline builder selected fromsodium tripolyphosphate ; potassiumhydroxide ; soda ash ( light ); trisodium phosphate ; tetrasodiumpyrophosphate ; tetrapotassiumpyrophosphate ; sodium hydroxide ; certain combinations of thesebuilders 5 % - 75 % wetting agent , preferably non - ionictype or acid - based anionic typeas set forth in the examples 0 . 5 % - 30 % flocculant 2 % - 40 % water 0 % - 90 % ______________________________________ it will be appreciated that the above ranges must be chosen in consideration with the overall result in that water if utilized in the concentrate should render the formulation readily soluble . also , if one component is selected in the high range , certain other active components should reasonably be lower . as a more specific range of workability , the following formulations , consistent with certain of the examples is provided : table ii______________________________________component content______________________________________an alkaline builder selected fromsodium tripolyphosphate ; sodiumsulfate ; soda ash ( light ); trisodium phosphate ; tetrasodiumpyrophosphate ; tetrapotassiumpyrophosphate ; sodium hydroxide ; certain combinations thereof 4 % - 40 % wetting agent , preferably non - ionictype or acid - based anionic typeas set forth in the examples 0 . 5 % - 15 % floatation agent , sodium alkylaryl sulfonate 0 % - 3 % flocculant , such as polydiallyl - dimethyl ammonium chloride ( average molecular weight 100 , 000to 300 , 000 ) polyacrylamides ( average molecular weight 2 - 15million ), or the copolymer ofdimethyl diallyl ammonium chlorideand acrylamide having a molecularweight of about 1 million 2 % - 40 % coagulation aid 0 % - 5 % water 0 % - 90 % ______________________________________ consideration as to ranges to be chosen are subject to the same parameters as indicated in connection with the formulations of table i . the working solution contains polyelectrolyte present in a range of from between 2 and 50 , 000 ppm . if less than 2 ppm are present , the flocculating capability tends to be less than that desired in the solution , and if greater than 50 , 000 ppm are utilized , the solution may tend toward gelation . normally , a range of between 100 and 20 , 000 ppm are utilized for effective performance . if desired for cetain applications , chelating agents may be utilized as a component in the formulation . also , perfumes and optical brighteners , as is conventional in detergent formulations , may be utilized to enhance the results obtained . it has been learned that a typical floor scrubber adapted for use with a standard commercially available detergent could cover a total of 68 , 000 square feet per 50 gallons working solution capacity on a floor which could be characterized as having light soilage present . this capability was based upon a commercial floor scrubber treating the floor on a one - pass basis . the same device , equipped with a modified or single detergent retaining tank of 50 gallon capacity and with a simple filter , and utilizing the detergent composition of the present invention ( example 1 ), can cover up to 228 , 000 square feet in a one - pass operation , this increased area being made possible by virtue of the recycling of the working solution during operation . in addition to the greater area capability , it was found that two separate passes were required with the apparatus using the standard detergent material in order to achieve a degree of cleanliness equal to that achieved with a single pass using the detergent composition of the present invention . the liquid delivery rate for a 26 - inch path is preferably in the range of about 21 / 2 gallons per minute . this provides a film of liquid on the floor which is relatively thick , and is in the range of about 4 mils . constant agitation of this film has been found to provide rapid and stable growth of flocs . the recycling capability of the detergent of the present invention makes it possible for recycling to occur a substantial number of times . it will be appreciated that the number of cycles will depend primarily upon the degree of soilage encountered , however recycling of 8 to 10 times under normally encountered conditions is readily achievable . also , for certain operations , it may be necessary to replenish the components of the detergent formulations herein , or in certain instances specifically the flocculant and floatation aid , if utilized , during recycling , since certain portions of these components are lost from the solution upon filtering .
