How to Mix Powder to Gel Soap?
Mixing powder to gel is easy and takes less than a minute! If you've never used a powder-to-gel product before, we made this quick guide to walk you through it.
The format is straightforward: a concentrated dry formula that activates with warm water, mixed at home in a reusable bottle. No special equipment. No complicated ratios. Just four steps, in order, and you're done.
Here's exactly how to do it.
What You'll Need
All you need is a bottle, a powder to gel refill pouch from Sustain Grooming and some warm water. Pick up one of our powder to gel starter kits if you don't have one already!
The 4-Step Mixing Process
The sequence matters here. Starting with a small amount of water before adding the powder to gel formula prevents clumping and makes the shake at the end much more effective. Follow the steps in order and you'll get a smooth gel every time.
Step 1 — Add a small amount of warm water to the bottle.
Add about an inch of water to the bottle before pouring in your powder to gel formula. This is the step most people skip on their first mix and the one that makes the biggest difference. The water creates a base that stops the powder from sticking when you pour it in.
Step 2 — Pour in the full contents of the pouch.
If you ordered a powder to gel Starter Set or a Bundle from us, then you will have a funnel to make this easier. Use your funnel to pour in the powder. Take caution not to breathe in any powder dust!
Step 3 — Fill the bottle to 80% with warm water.
Not to the top — to 80%. This is just above the top of our logo on your bottle. Leaving headspace is what makes the next step work. Warm water activates the powder to gel formula faster than cold, so don't skip that detail!
Step 4 — Seal the bottle firmly and shake.
Cap it tight, then shake for 10-15 seconds. You'll feel the powder to gel formula change as you shake it. Set it down, let it settle for a minute, and pump as normal.
At first the formula will be a bit watery. This is normal. Expect it to thicken up into a gel over the coming hours.
A Few Things Worth Knowing
The powder to gel formula continues to thicken slightly over the first few hours. If it looks a little thin right after mixing, give it time — it will settle into the right consistency on its own. You can use the soap immediately!
Warm water is the key variable. Cold water works but takes longer to activate. If you're refilling a bottle that still has some product left in it, that's fine — try to rinse it out if you can. Once that's done, pour the new powder to gel pouch in, top up with warm water, seal, and shake.
Frequently Asked Questions (FAQ)
Why do I need to add water before the powder?
Adding a small amount of warm water first creates a liquid base that allows the powder to gel formula to disperse evenly when you pour it in. If you add powder to a dry bottle and then add water, the powder to gel formula can clump against the sides and take much longer to activate fully.
What happens if I fill the bottle all the way to the top?
You need headspace for the shake in Step 4 to work properly. A bottle filled to 100% doesn't have room for the contents to move, which means the powder to gel formula won't mix evenly. This can cause clogs to interfere with your pump. Fill to 80% and leave the rest as air.
Can I use cold water?
Yes, but warm water activates the powder to gel formula more efficiently and produces a more even consistency right after mixing. If warm water isn't available, cold works — just shake a little longer.
How long does it take before the product is ready to use?
It's ready immediately after shaking. The powder to gel formula will continue to thicken slightly over the first hour as it fully sets, but you can use it right after mixing. If it feels thin at first, that's normal.
What do I do with the empty pouch?
The pouches are made with kraft paper and PLA. These materials are compostable and recyclable. Check your local area for any compostable restrictions.
