Muscle Contraction and Antibacterial Soap.

Using antibacteria soaps and gels? New study suggests you think twice. We knew of its alleged endocrine disrupting properties, but this one shocked us.“triclosan disrupted communication between two proteins crucial for proper muscle functioning, causing failure in both the heart and skeletal muscle cells.”
“triclosan penetrates the skin and enters the bloodstream more easily than previously thought. A new paper, (Triclosan impairs excitation–contraction coupling and Ca2+ dynamics in striated muscle) published today in the Proceedings of the National Academy of Sciences, indicates that triclosan impairs muscle function in both animals and humans. The study found that the chemical hinders human muscle contractions at the cellular level and inhibits normal muscle functioning in both fish and mice.
