Why do we use it in formulations?

We use distilled water in our formulations because it removes the variable of whatever might be in tap or mineral water. Learn more here.

Do you need it?

Yes

Strengths

Inexpensive, generally easily available, low-variable water.

Weaknesses

It doesn’t come out of your tap?

Alternatives & Substitutions

De-ionized water is a good alternative, and tap water will likely work in a pinch assuming your tap water is clean and not extremely mineral heavy. You can learn about other alternatives here.

If you’d like to fancy up a formulation you can swap some of the water for other watery-type ingredients like aloe vera juice, witch hazel distillate, or hydrosols.

How to Work with It

Use as the formulation directs—it’s an extremely flexible ingredient!

Storage & Shelf Life

Stored somewhere cool, dark, and dry, distilled water should last indefinitely.

Tips, Tricks, and Quirks

Distilled water is not sterile—it simply lacks the minerals and salts that can be found in tap water or mineral water.

Recommended starter amount

4L (1 gallon)

Where to Buy it

I recommend buying it from your local grocery store; you’ll be buying it roughly 4L/1 gallon at a time (at least) and you don’t want to pay to ship that!
