<p>Detergent bars, intended for personal use, which are of good foaming, lather, solubility, wear, slough, hardness, mildness (to the skin) and tactile characteristics, and which are homogeneous so that users of such bars will detect no surface grittiness on washing with them, even in cold water, include in the composition thereof, water soluble higher fatty monoglyceride sulfate, water soluble higher fatty acid soap and higher fatty acid, preferably of certain types and in certain proportions. Such bars may be made by facturing process,in a step of which the higher fatty acid soap and higher fatty acid are dissolved in an aqueous lower alcoholic extractant solution of the water soluble higher fatty monoglyceride sulfate. Also within the invention is such a process for manufacturing such detergent composition bars, in which the extractant solution of the monoglyceride sulfate, preferably in aqueous isopropanol, is employed to dissolve kettle soap and higher fatty acids, after which the solution is quick-dried, as in a film dryer, preferably of the wiped film type, after which usual adjuvants may be incorporated in the composition, as in a soap amalgamator, and the amalgamator mix may be further processed to bar form, as by milling, plodding, cutting to lengths and pressing to final shape.</p> |
