  • Tap Water and Chelator

    Pardon my ignorance here guys. I have always used distilled water to make my products along with a chelator. I was sent a few formulas that just say water and I was wondering if it’s fine to just use tap water as long as it includes a chelator?

    Well, that depends on the quality of the tap water. You might be able to use it, but you might not be able to use it.

      Thanks for responding Perry. I was thinking about regular tap water/city water.

        The company I worked for regularly used city tap water for batches but it was usually filtered. But in the lab we always used deionized water.

    You would need to test and even then I would be reluctant. You could have microissues. I also believe you would have cGMP issues if audited. I know of a company in Tampa that tried this and their auditor was not a fam whatsoever.

    To Microformulation’s point, city water typically includes Pseudomonas aeruginosa etc. at some level, typiucally in a biuofilm context. IF you use it, you should heat it 1st -prefer 80C but at least to minimal Pasteurizing levels - ~60C.
