The world as we know it could not function without acids and bases. These chemical compounds are used extensively, from the chemical laboratory to the manufacturing industry. They are necessary for the proper functioning of the human body and for the health of the environment, too. Acids taste sour, break down metals, and react with bases. Without acids, soft drinks, lemonade, and tomato sauce would not taste the same way. Bases taste bitter, feel slippery, and react with acids. Without bases, cakes would be hard and flat, and laundry detergent would not clean. Both acids and bases can change certain vegetable substances a variety of different colors, and they can burn through human skin if not handled properly. Without acids and bases, we would not have dynamite, some heart medications, and fertilizers. On the other hand, without acids, we would not have damaging acid rain. And... 

Mannheim (1) A process for making hydrochloric acid by roasting sulfuric acid and sodium chloride together in a closed cast iron furnace equipped with a plough. The byproduct sodium sulfate, known as salt cake, may be reciystallized after neutralization and filtration, and used as a detergent ingredient. A potassium variant is used in those locations where native potassium chloride can be found. 

In addition to its uses as a herhal remedy, the primary use of cinnamaldehyde is as a food additive to enhance the flavor and/or odor of food products. It is used most commonly in cake mixes, chewing gums, chocolate products, synthetic cinnamon oils, cola drinks, ice creams, soft drinks, and vermouth. The compound is also added to a number of cosmetics and home care products to improve their odor. Such products include deodorants, detergents, mouthwashes, perfumes, sanitary napkins, soaps, and toothpastes. Finally, cinnamaldehyde is used to some extent in agriculture as an insecticide and fungicide. 

Even before the first world war, the cleaning industry had begun to desire more alkaline detergents. The Puritan Soap Co. suggested combinations of silicate and soda ash, but all such combinations seemed liable to cake in their containers,... 

A patent (29) claims a non-spray dry process (heated screw conveyer) for making a free flowing, non-agglomerating, soluble silicate. In another process (30), detergent granules are sprayed with a combination of sodium silicate, sulfate, or hydroxide and Al or Mg sulfate to reduce caking in storage.
