Home Cosmetic Science Talk Formulating General Water source/spec for facial care products

  • Water source/spec for facial care products

    Posted by SkinNP on June 18, 2019 at 5:18 pm

    Writing to see if anyone cares to share their view on the “standard” or best practice for sourcing water used in production of facial care products. I read the February thread in which someone suspected water from the municipal line might be causing color shift. I want to know in the real-world what water most people use for production batches (e.g., deionized, distilled, demineralized). Thanks!

    I prefer distilled water of pharmaceutical quality (PhEur/PhH).

    Many of the facilities that I have worked at or toured utilize deionized water. They will purchase a system to produce this grade. These systems are maintained and quite common.

    Nobody should use municipal/potable grade water.

    We always used deionized water in both the lab and in production.

    We use RO water (with a stringent testing protocol) both in production and lab.

    We use RO water with regular in-house testing plus annual test by external lab to confirm our in-house tests.

    We use only the finest organic vegan natural water, harvested from morning dewdrops on succulents in the high sierra, by indigenous fairtrade peasants clad entirely in recyclable textiles.
