<p>[QUOTE=&quot;SuperDave, post: 2547191, member: 1892&quot;]These are the active ingredients in MS70 (the MSDS is freely available online; you can easily confirm this):</p><p><br /></p><p>2-butoxyethanol</p><p>Potassium Hydroxide</p><p>Sodium Gluconate</p><p>sulfonated Sodium salts</p><p><br /></p><p>Rather than dictate what&#039;s real, I&#039;ll leave it to the reader to determine what effect, if any, these things either alone or in combination can do to the phthalates used to soften PVC. I will say it <i>seems</i> like the Potassium Hydroxide should at least neutralize the hydrochloric acid formed by the interaction between PVC and silver, but I&#039;m not completely sure of what the combination with the other ingredients in MS70 does to/for it.[/QUOTE]</p><p><br /></p>
