Milling soap-base

And in the case of milling soap base and household soaps,... 

Bleached palm oil, olive oil, castor oil and lard are also employed in the production of special milling soap bases, a palm oil soap being specially suitable for the production of a violet-scented toilet soap. 

The Merquat , titanium dioxide, colorant and fragrance are mixed with the soap base, which has been milled once previously. This mix is then milled three further times, followed by plodding, extruding and stamping into bars. 

Prolonged milling, especially with a suitable soap base, tends to produce a semi-transparent appearance, which is admired by some, but the increased cost of production by the repeated milling is not accompanied by any real improvement in the soap. 

Greases are also made from soaps of strontium, barium and aluminum. Of these, aluminum-based grease is the most widely used. It is insoluble in water and very adhesive to metal. Its widest application is in the lubrication of vehicle chassis. In industry, it is used for rolling-mill applications and for the lubrication of cams and other equipment subject to violent oscillation and vibration, where its adhesiveness is an asset. 

After resting for several hours, half-spent lye settles to the bottom of the pan. In the case of yellow soaps or milling bases the settled j/ lye is removed to a suitable receptacle and reserved for use in the saponification of other material, and the soap is then ready for the final operation of fitting... 

With milling base, this is successfully accomplished in the Gres-sonni res plant, by allowing the hot soap to fall upon the periphery of a revolving drum which can be cooled internally by means of water. 

Only soap made from best quality fats is usually milled, a suitable base being that obtained by saponifying a bltmd of tbc finest white tallow with a proportion, not exceeding 25 pcjr cent, of coc oa-mit oil, and prepared as described in Chapter V,... 

The first essential of a milling base is that tlu sa Kmificatic>n should be thorough and complete if this is not ensured, rancidity is hable to occur and a satisfactory toilet soap cannot b prcKluccd. The soap must not be short in texture or brittla ami liable to split, but of a firm and somewhat plastic consistency. 

Despite the electronic communications revolution, paper production continues to grow worldwide at a rate of 2% to 3% annually. Much of the incremental increase is based on pine because no other long-fibered softwood offers such high yield rates per hectare coupled with a short growth cycle. New kraft pine pulpmills and most existing mills will continue to practice tall oil recovery because non-removal of tall oil soap from kraft black liquor adversely affects evaporator and recovery boiler capacity (14). Increased tall oil production has been accompanied by new fractionator capacity in Europe and incremental expansion in the United States. Since the paper industry is the largest user of rosin size, it might be expected that the increased paper production would absorb the increased availability of tall oil rosin. 

Current mass market soap manufacturing is based primarily around continuous soap making using either fat saponification or by fatty acid neutralization, utilizing a wide variety of natural and synthetic feedstocks. The soap chips produced are then usually finished using a high-speed soap line comprised of refiner mill, extruder, and stamper. Batch...
