Description
United States atent PROCESS FOR PREPARING AQUEOUS SOAP- SYNTIETIC DETERGENT MIXTURES IN RIBBON FORM Russell Edward 'Compa, Bogota, Nah, assignor to C01- gate-Palmolive Company, Jersey City, N..l., a corporation of Delaware No Drawing. Filed Aug. 9, 1955, Ser. No. 527,407 7 Claims. (Cl. 252-121) The present invention relates to a process for preparing aqueous soap-synthetic detergent mixtures in the form of ribbons suitable for drying in belt conveyor-type driers. More particularly it relates to a process for preparing ribbons of soap and fatty acid monoglyceride sulfate detergent which are suitable for processing into chip form, and thence into toilet bar form.
It has previously been proposed to prepare soap-fatty acid monoglyceride sulfate detergent bars so as to realize the desirable properties of both soap and the synthetic detergent within a single bar. Various methods have been proposed for preparing such bars, one of such methods consisting of dry milling in which soap chips, containing usually about to 10% moisture, are mixed with substantially dry particles of the synthetic detergent, the mixture is passed through milling rolls to grind and homogenize the ingredients, and the mixture is then plodded, cut, and stamped in the fashion of soap bars.
This dry milling procedure is not entirely satisfactory in that such milling seldom effects complete homogenization-some discrete particles usually remain in the final product, which may even have a speckled appearance.
A satisfactory method of producing a more truly homogeneous soap-fatty acid monoglyceride sulfate detergent combination bar" involves wet mixing. In this process, the synthetic detergent, in the form of an aqueous slurry, is mixed with ordinary kettle soap, the aqueous mixture is thoroughly agitated to achieve uniformity, and the homogeneous mixture is then processed similarly to ordinary toilet soap, i.e., it is fed to a'chill roll, taken off as ribbons, dried in a belt conveyor-type drier, and broken into chips which are then milled, plodded and stamped in the manner of soap bars.
The wet mixing procedure is highly satisfactory for combination bars containing a maximum of up to about 25 to 30% of the synthetic detergent. Unfortunately, above this range of synthetic detergent content, the wet mixture gradually loses certain of its soap-like characteristics and normally does not coagulate sufficiently on a chill roll to enable the development and removal from the roll of numerous form-retaining ribbons. Rather, an amorphous, soft sticky elongated mass forms where the serrated ribbon-forming removal blade contacts the drum. These masses frequently have the appearance of and are referred to as cigars. Such cigars are highly undesirable as they cannot be properly supported and dried on the woven mesh belts of the belt conveyor-type driers employed in soap processing. Thus, it previously has not been possible to satisfactorily handle mixes containing relatively high proportions of the synthetic detergent in conventional soap-processing equipment.
It has now been discovered that by the proper selection of higher fatty acid soap, it is possible to carry out the wet mixing" process with compositions containing as much as about 65% fatty acid monoglyceride sulfate detergent and still obtain a form-retaining ribbon on chilling the wet mix. In accordance with the present invention, a process for the preparation of homogeneous form- 2 V retaining ribbons of an aqueous mixture of synthetic deterrgent and soap, suitable for drying on belt conveyor-type driers and processing into toilet bars, comprises forming a homogeneous aqueous mixture of fatty acid monoglyceride sulfate detergent and sodium soap of a substantially completely saturated higher fatty acid containing at least about 16 carbon atoms, said soap comprising about 35 to 70% of the solids in said aqueous mixture, chilling said mixture in sheet form to a temperature below its setting-up point, and dividing the resulting chilled sheet into form-retaining ribbons. The thus formed ribbons may be dried in a conventional belt conveyor-type drier, milled, plodded into bar form, cut and stamped.
The crux of the present invention is the discovery that by employing substantially completely saturated soaps of the higher fatty acids, i.e., palmitic and stearic acids or mixtures thereof such as hydrogenated tallow, it is possible to prepare a form-retaining ribbon under conditions which normally lead merely to the formation of soft amorphous masses, i.e., cigars. It has been found that to satisfactorily carry out the process of the present invention, the saturated higher fatty acid soap employed must constitute a minimum of about 35% and preferably about of the composition to be prepared. Normally, the instant soaps will not form more than about'65% to 70% of the final product, as, at higher soap contents more conventional soaps process satisfactorily and are more desirable from the viewpoint of rapid foaming and increased solubility, due to the diminished proportion of the synthetic detergent present. The soaps of the present invention normally have an iodine value (I.V.) of a maximum of about 15, and when the proportion of soap is relatively low, preferably less than about 5. While the soap may be prepared in situ by neutralization of the proper fatty acid with caustic or other base, it is preferably supplied in the form of kettle soap containing about 65 to 70% solids and 35 to 30% water.
The synthetic detergent of the instant invention is a sulfated higher fatty acid monoglyceride as exemplified by hydrogenated coconut oil monoglyceride sulfate, coconut oil monoglyceride sulfate and tallow monoglyceride sulfate, and, more broadly, sulfated monoglycerides of fatty acids containing about 12 to 18 carbon atoms and mixtures thereof. Under certain circumstances this material may be replaced in part by suitable amounts of higher fatty alcohol sulfates containing about 8 to 18 carbon atoms.
The fatty acid monoglyceride sulfate detergent, when intended to be mixed with kettle soap, contains about 60%, and preferably about 70% detergent solids, the remainder being substantially completely water. Thus, the aqueous mixture of soap and synthetic detergent normally contains about 70%, and not less than about 65 solids, or, putting it inversely, the aqueous mixture normally contains no more than about 35% water, as mixes containing a higher proportion of water are generally unsatisfactory in that ribbon formation becomes difiicult therewith. Of course, suflicient water must be present so that the mixture is fluid and easily homogenizable (i.e., about 30%).
Preferably the fatty acid monoglyceride detergent is free of accompanying sodium sulfate. However, it is one modification of the instant process to have present in the aqueous mixture of soap and the synthetic detergent, up to about 4 to 5% of sodium chloride which acts to shorten the soap-synthetic detergent mixture and render it more amenable to easy coagulation and ribbon formation on the chilling roll.
The mixing of the soap and the synthetic detergent occurs at an elevated temperature (i.e., normally about to F.) above the setting or setting-up point Patented July 12, 1960 tures commonly realized on chill rolls (which'are' nor mally cooled to about 55-65? F). i
The following example'sare given to additidnally'illustrate the nature of the invention and it'will be understood that the invention is not limited thereto. (All parts are by weight unless otherwise specified.)

The chips are mixed with perfume, preservative and titanium dioxide and are then milled, plodded,' cut and stamped into finished cakes. 1 g g The instant soap-synthetic detergent mixtures are not narrowly limited to soap or synthetic detergent as con stituents. Although there are their principal components, there may also be present in the final bars small proportions or various other substances such as slip improving agents, e.g., carboxymethylcellulo'se, higher fatty al-f cohols, and diethylene glycol monostearate,- germicides fillers, builders, coloring matter, pigments, dyes and the like. Furthermore, compositions processed according to the instant invention are not restricted to use in pre-' paring toilet bars but may be used in chip, pulverized or other form for any desired purpose.
While there has been disclosed and described what is at present considered to be the preferred embodiments of the invention it will be understood, of course, that many changes, modifications, and substitutions may be made therein without departing from the true scope of the invention as defined in the appended claims.
