Alum cream

Cetostearyl alcohol, ethoxylated castor oil, lanolin alcohol, octyldodecanol, and white petrolatum weighed and mixed in the ratio defined above are heated to 60°C. 

Alum and item 7 are dissolved in water at room temperature, and then the solution is heated to 62°C. 

Both phases are combined in an ointment mixer and homogenized by stirring. 

While stirring, the cream is cooled to about 30°C, and its weight is supplemented with purified water. 

The cream is again homogenized by stirring and then filled into an electrolyte-resistant storage bottle.

The commercial dry alum most often used in wastewater treatment is known as filter alum, and has the approximate chemical formula A 12(804)3 T4H2O and a molecular weight of about 600. Alum is white to cream in color and a 1 percent solution has a pH of about 3.5. The conunercially available grades of alum and their corresponding bulk densities and angles of repose are given in Table 1. 

Elderberries yield a violet color. In times past, not only were the berries used to color hair and wine, but also to enliven fabric and basket materials. Elder-berries have also been used to make beautifully colored inks and to tint paper blue. With alum used as a mordant to fix the dye, the berries give a purple color, used best on wool and silk. Elderberries mixed with alum and salt produce a lilac hue, and mixed with alum and cream of tartar they make a lovely crimson shade. Chrome used as a mordant with elder-berries produces a blue dye and tin used as a mordant produces blue gray. 

Long before sodium and potassium metals were isolated, many of their compounds were in common use. Among the most important of these were potash (potassium carbonate), cream of tartar, saltpeter, alum, common salt, Glaubers salt, and soda (sodium carbonate). Both potash and soda have been used since ancient times in the manufacture of glass.

The fabrics were dyed by the authors for uniformity of treatment and because naturally dyed cloth was not otherwise available. The processes used in this dyeing were those suggested by Kramer in Natural Dyestuffs (12). Alum was used as a mordant in all dyes except indigo where cream of tartar was used other mordants might yield different results. 

Metals other than those in supplement formulations are used extensively in pharmaceutical products and are added at various concentrations as an aid to health benefits, or as fillers or encapsulants. Magnesium hydroxide is used as a gentle laxative while aluminium present as hydroxide, lactate, salicyclates, acetates and alums is used frequently in a number of dermatological products. Metals in creams, lotions and powders are also part of the pharmaceuticals range. The metals formulated into pharmaceutical products are salts of p-block metal ions and the following is a brief outline of their use in medicine ...
