| Abstract from DBPedia | Soap is a salt of a fatty acid used in a variety of cleansing and lubricating products. In a domestic setting, soaps are surfactants usually used for washing, bathing, and other types of housekeeping. In industrial settings, soaps are used as thickeners, components of some lubricants, and precursors to catalysts. When used for cleaning, soap solubilizes particles and grime, which can then be separated from the article being cleaned. In hand washing, as a surfactant, when lathered with a little water, soap kills microorganisms by disorganizing their membrane lipid bilayer and denaturing their proteins. It also emulsifies oils, enabling them to be carried away by running water. Soap is created by mixing fats and oils with a base. A similar process is used for making detergent which is also created by combining chemical compounds in a mixer. Humans have used soap for millennia. Evidence exists for the production of soap-like materials in ancient Babylon around 2800 BC.石鹸（石鹼、せっけん、シャボン、葡: sabào）は、一般に汚れ落としの洗浄剤を示す語である。また高級脂肪酸の塩(えん)の総称である。 一般用語としての石鹸と化学用語としての石鹸は重なり合うことが多いが、化学的には石鹸ではないものが一般的に石鹸と呼ばれている場合や、その逆の場合がある。 (Source: http://dbpedia.org/resource/Soap) |
