Please do not add or change content, as you did at soap, without citing a reliable source using an inline citation that clearly supports the material. The burden is on the person wishing to keep in the material to meet these requirements, as a necessary (but not always sufficient) condition. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you. Materialscientist (talk) 23:53, 4 February 2017 (UTC)
