Dead Sea salt : ウィキペディア英語版 | Dead Sea salt
Dead Sea salt refers to salt extracted or taken from the Dead Sea. The Dead Sea is popular with tourists from all over the world for its reputed therapeutic effects. The water of the Dead Sea has a salt content of 29%, compared to 4% in the oceans,〔(History of the Dead Sea )〕 and is consequently substantially denser. This allows anyone to easily float on Dead Sea water because of its greater density. Its mineral composition is also different from ocean water since only 12–18% of Dead Sea salt is sodium chloride. A 2006 analysis of a commercial Dead Sea Salt product measured a 2.5% sodium chloride content; by comparison, 85% of the salt in normal ocean water is sodium chloride. == History == Various cultures and groups of people have visited the Dead Sea for therapy, dating back to the time of the ancient Egyptians,〔Ma’or, Zeev et al. ("Antimicrobial properties of Dead Sea black mineral mud" ), International Journal of Dermatology, May 2006. Retrieved on 2008-04-13.〕 utilizing the salt in various unguents and skin creams, as well as soaps, just as it is used today.〔The Rough Guide to Jordan: the rough guide. Matthew Teller, Ian J.
