Deionized v.s. Distilled

[Guest guest]

I have obtained a formulation that I’d like to play with, but it asks for

“deionized water”. I only have distilled water purchased in a jug from the

grocery store.

After further research, I found this from a discussion group:

“I'm not knowledgeable about the engineering aspects such as the cost of one

compared to the other. However, as the names imply deionized water is water

that has been passed through a column or membrane to remove ions present. If

it is of the type used in homes, it is not truly a de-ionizer, removing all

ions, but rather an ion exchange column that exchanges polyvalent ions such

as Mg++ and Ca++ for Na+ ions. A de-ionizing column will not remove nonionic

organic substances from the water.

In contrast, distilled water is actually boiled in a still and the

condensate collected and distributed. Distillation removes both ionic and

nonionic organic contaminants.

Either method will require periodic regeneration, in the case of a

deionizer, or cleaning in the case of a still. I think you will have to

weigh the cost of maintenance and the required capacity needed before making

your decision.

After reading this, am I to assume that deionized and distilled are the

same?

Thanks,

You are correct in your assumption. It's just two different ways of getting

what you bought in that jug at the store. Distilling is typically cheaper,

easier and faster. Any backyard chemist can do it.

They are the same. Distilled means that water has been boiled, evaporated and

the vapors captured. These captured vapors make 'distilled' or deionized water.

Deionized means that all of the unnecessary negative and positive electrons have

been removed (by evaporation) and all you are left with is pure H2O.

,

Distilled water can be used to replace deionized water in your personal care

formulas. To be purified, it should be held at 170 F for 20 minutes before

using in your formulations.

Best wishes for a wonderful holiday season,
