Colloidal Oats - Let's Make Our Own!

This is simply a matter of patience and a couple of good tools. And, if you happen to bake, there's double bonus here (all shall soon be revealed!).

Today, we're going to make our own version of colloidal oats! Shall we get started?

What's Colloidal?

The word colloidal comes from the word colloid, which is a mixture in which one substance (such as oats) is microscopically dispersed in another (such as water, hydrosol, or any liquid).

Here's an illustration of a stable and an unstable colloid

Colloidal Oats

As oats in their natural state (and size) will tend to act like the example you see on the right, the object of this exercise is to create an oaty powder so fine and light that it disperses evenly and effortlessly in our chosen liquid.

To disperse perfectly (and to make true colloidal oats) takes a bit more equipment and doing than we can do in a DIY setting. But we can approximate a more evenly dispersible ingredient by grinding, sifting, and sifting some more.


You'll need
  • a coffee grinder (I used my dedicated cosmetics grinder) 
  • a sieve
  • bowls
  • container 

Start by grinding the oats thoroughly.
Tip: You're going to be using a bit more than you might think, so grind up a fair sized portion.

Pass the ground oats through your sieve.
Pass them through again.
And again.
And again.
As you continue sifting, remove the large oat bits and place them into a separate bowl.
Below: what was left in the sieve after 3 passes.

When you have achieved the silkiest, smoothest powder you think you can possibly achieve, your oats are ready to be packaged in an airtight container and labelled with a date until you choose to use them in your bath, face cleansing powder, or other lovely product.


If you check the picture at the very top of this post, you'll see how much there was left after grinding, sifting and sifting some more.

The cup on the left holds the sifted oats. The bowl on the right is the leftovers.

Now, if you're anything like me, you can't bear the thought of tossing the leftovers and want to find something to use them for.

Since I'm living in Scotland, I'm getting used to have porridge at breakfast. I really really love oats, they are soooooooo goooooooood for skin...
I love them sprinkled for rash skin, and I loooove an oats bath: put some oats in a muslin cloth with lavender essential oil and let it simmer like a tea bag on your bath water. Just amazing!

You and I both María! I'm a huge fan as well

Jennie Widdicombe said...

I make my own ground oats. I didn't realise I need to sieve so many times, I've just been doing it once. It certainly takes up a lot less space

Lise M Andersen said...

Hi Jennie - You can kind of decide when you are finished by testing the feel and function of the powder. Some folks grind and leave it at that. It's a question of taste and of course what you want to use it in.

When you say left over what do you mean? The bowl isn't useable for the bath products? What makes it left over?

Lise M Andersen said...

Hi Anon - I mean the part of oats that is leftover after sifting and sifting and sifting. That's what I mean by leftover. :)

I didn't know it had to be sifted. That's great! Thank you Lisa!❤

Lise M Andersen said...

Hi Ladybug - I suppose if you have a serious enough grinder, you could do without sifting.

Stephanie said...

I'm another one who did not know about the sifting step. Makes sense though. I love using finely ground oats as a gentle scrub... now I can make them even finer! Thanks Lise :)

Lise M Andersen said...

HI Stephanie! Pleasure to hear from you! I found the sifting helps quite a bit - enough to where it works for my needs.

Hello Lise,

I just discovered your blog through the interview you did with Marie from Humblebee. Glad to find another great resource on skincare! I also love colloidal oatmeal. Love it in the baby bath and mixed in with other goodies for a nourishing face mask. I'm actually working on a dry powder massage with some plant based ingredients and colloidal oatmeal for an upcoming workshop. I can't wait to check the rest of your blog.Thanks!

Hello Paula and thank you for stopping by! I hope you find a lot of useful info and inspiration :)
