Water for Cosmetic Industry

tecnico3vinia

Hey!

I work at a cosmetic R&D lab but have limited knowledge about the manufacturing at large scale. I'm just curious about the most suitable (if there's one) type of water destined to cosmetics production at large scale (e.g: dieonized water, demineralized water, distilled water, etc).

I think that there's no specific rule about it (at least according to my country's regulation; they just say that the water has to be at least safe to be drank), and I also think that is strictly up to the manufacturer to decide what type of water he would prefer to use, but I'd like to hear from your experience, specially from those with experience at cosmetics manufacturing facility. 

Any help/answer would be appreciated!

I think most companies use deionized water. See this post on the subject of water for cosmetics.

Big cosmetic companies invest very significantly in their water systems - in no way would potable water standards satisfy their water quality specs.  With tools such as RO, DI, to ozonation and high heat their water systems are better than many pharma operations.

Thank you, Perry! I'll definitely read through it.

Thank you, Phil! In our lab we use a reverse osmosis and deionization system, but I'll definitely check the ozonation and high heat methods.

Those are for water preservation  in circulating systems post treatment - hot loop at 80C and cold loop with ozone and UV at drops

I've seen many products listing "Deionized Water" instead of just "Water" in their ingredient list (or "Eau"), even in technical dossiers. If there's no need to specify the type of water, why do brands put it that way?

Also, is it fair to use, for example, "Demineralized water" (or other water) as a claim for the product?

Perry

Brands that label their cosmetics in this way are violating the rules of the INCI dictionary labeling and thus the FDA rules too.

You can claim "Demineralized water" and even "Deionized water" in your label copy. But in your ingredient list the only allowed word to describe it is...WATER (or Aqua or Eau in another country)

Why brands label their water? I assume they think there is some marketing advantage to it.
