Water source/spec for facial care products
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.

Distilled and deionized water.

Very appreciative! Thanks

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.
