Line 1: [[File:Tualetsapo.jpg\|thumb\|right\|A bar of soap]] '''Soap''' is a [[chemical compound]] resulting ~~from~~afrom the reaction of an alkali (commonly sodium or potassium hydroxide) with a fatty acid. When mixed with [[water]] during [[bath]]ing or [[washing]], they help people and clothes get [[hygiene\|clean]] by lowering the chance of [[dirt]] and [[oil]] to get to the skin or [[fabric]]. Soaps are made from [[animal]] [[fat]]s or [[vegetable]] [[oil]]s. There are two basic steps in making soap. They are called Saponification and Salting-out of soap. Soap cleans very well in [[soft water]]. It is not [[Toxicity\|toxic]] to water life. It can be broken down by [[bacteria]]. However, it is slightly [[Solubility\|soluble]] in water, so it is not often used in [[washing machine]]s. It does not work well in [[hard water]]. It cannot be used in strongly [[acid]]ic [[solution]]s. Hand soaps are only acidic enough to remove unwanted skin oils. For other forms of oil, Dishwashing soap is acidic enough to remove almost all forms of oil without damaging other petrolium products such as Plastic. It does not damage skin either.
