Soaps silicated

As far back as 1838 Mr. Sheridan—the original inventor of silicated soaps — patented a process for combining potato flour, water, and soda or potash leys (preferring the latter alkali) in the following proportions —potato flour, 16 lbs. water, 270 lbs. potash leys, 100 lbs. It will be seen, as is too frequently the case with improvements in soap, that the same idea has been often patented since.

Silicated Soaps. The determination of free alkali and silica in silicated soaps is embodied in a report of the Analytical Methods Committee of the S.A,C. to which reference should be made if required. 

Vitreous, colourless form of free silica. Formed when quartz is heated to 870°C (1598°F). Aporous siliceous rock resulting from the decomposition of chertorsiliceous limestone. Used as a base in soap and scouring powders, in metal polishing, as a filtering agent, and in wood and paint fillers. A cryptocrystalline form of free silica. 

A hydrous magnesium silicate used in ceramics, cosmetics, paint and pharmaceuticals, and as a filler in soap, putty and plaster. 

A powdered soap-based laundry detergent contains 44% tallow soap, 18% sodium salt of a-sulfonated 1 1 methyl stearate-methyl palmitate mixture, 9% sodium silicate, 10% Na2S04, 2.5% ethoxylated cocoethanolamide, 1.4 cellulose, 0.2% fluorescent whitener, 0.7% enzyme, 0.5% perfume, and 5% water [77]. 

A soap-based powder can be produced in combination with ester sulfonates. Thirty-five percent of a sodium soap mixture (5% lauric acid, 5% myristic acid, 52% palmitic acid, 21% stearic acid, 12% oleic acid, and 5% linoleic acid) is mixed with 15% sodium a-sulfo palm oil fatty acid methyl ester, 3% lauric acid ethoxylate, 5% sodium silicate, 17% sodium carbonate, 20% Na2S04- 10H2O, and 5% water [79]. 

A detergent, imparting better flexibility to cotton cloth is produced by adding 1% sodium a-sulfo hardened tallow fatty acid methyl ester and 9% disodium a-sulfo hardened palm oil fatty acid to a mixture of 5% sodium n-dodecyl-benzenesulfonate, 5% a-C16-olefmsulfonate, 3% dimethyldistearylammonium chloride, 15% zeolite, 10% sodium silicate, 10% sodium carbonate, 2% soap, 35% Na2S04-7H20, and 5% water [84],... 

Addition of suitable builders, such as sodium silicates or sodium tripolyphosphate, could increase the detergency of soap-LSDA blend even further. A systematic investigation of three-component systems, soap-LSDA builder, showed that a detergency maximum could be attained which corresponded to a certain fixed ratio of components. Maximum detergency corresponded to an approximate composition of 75% soap, 10% MES, and 15% metasilicate. The tests were carried out at 50°C and at 300 ppm water hardness which is well above that of U.S. municipal water supplies. The principle of detergency potentiation of soap by an LSDA and builder was always evident, even when using other artificially soiled cloths, such as those supplied by U.S. Testing Co. or Testfabrics Inc. 

Over 50% is used to make glass. Other uses include the preparation of chemicals (such as sodium silicate and sodium phosphate), soaps and detergents, in the pulp and paper industry, and in water treatment. Substantial amounts are exported. 

Vermiculite and as a filler in soap, putty and plaster. An expanded mica (hydrated magnesium-aluminium-iron silicate). Used in lightweight aggregates, insulation, fertilizer and soil conditioners, as a filler in rubber and paints, and as a catalyst carrier. 

A bar of talc feels like a bar of soap which is why it is often called soapstone. Its exceptional softness (it is the softest of the Mohs minerals) is a direct result of its unusual crystal structure. This consists of sheets of silicate tetrahedra without metal ions between the sheets. Thus the sheets are bonded only by London polarization forces. The latter are particularly weak because silicate tetrahedra have relatively small polarizabilities. 

The importance of thermally stable char was shown to be critical in a further study of siloxane block polymers by General Electric researchers. (18). The char enhancing action of magnesium soaps and a special silicate silane (19) and likewise the char stabilizing action of lead salts (20) were demonstrated in polyolefins by General Electric investigators.

Among the precipitants employed were tannic acid, tartar emetic, rosin soaps, fatty acid (stearic, oleic) soaps, sulphonated oils (Turkey red oil), earth lakes (mixed natural silicates), phosphates, casein and arsenious acid. The fastness properties of these pigments... 

Sodium silicate (Na O) is known as water glass and is used in water treatment and in making soaps, detergents, adhesives, drilling fluids, bleaches. 

Sodium silicate (Na SiO ), better known as water glass, is one of the few silicon compounds that dissolves in water. Produced at high temperatures (SiO + 2NaOH + heat—> H O + Na SiOjj, it is used in the manufacture of soaps, adhesives, and food preservatives. 

In medicated soaps, substances of medicinal value are added. In some soaps, deodorants are added. Shaving soaps contain glycerol to prevent rapid drying. A gum called, rosin is added while making them. It forms sodium roslnate which lathers well. Laundry soaps contain fillers like sodium roslnate, sodium silicate, borax and sodium carbonate.
