What’s a substitute for borax?

Let’s talk about the pink elephant in the room, borax! In some places borax powder is banned or highly discouraged and that’s fine. There is a ton of controversy surrounding it, and to be honest borax powder slime is my least favorite slime to make. It’s finicky.

HOWEVER, a lot of people out there, bloggers included, are sharing “safe” alternatives to borax slime by using saline solution or liquid starch. Read below!

However, saline solution, liquid starch and even some contact solutions contain ingredients from the boron family. Therefore none of these products are a good borax substitute. If you have an allergy or a problem with borax, make sure you know the facts before you decide.

With that said, saline solution slime and fluffy slime are my most favorite slime recipes to make. They are so much fun, but hey, they are technically NOT borax free.

Borax Slime vs Borax Free Slime

Borax free slime will not necessarily behave or feel like a classic borax slime. The slime will not last as long either, and is best played with on the day it is made. Please don’t be discouraged by the texture or the characteristics of these borax free slimes.

However, the following borax free or non toxic slime recipes are perfect for our littlest scientists. Each slime recipe still contains a bit of science too, since science is chemistry of course!

A chemist will mix several ingredients and form a new substance from the chemical reaction. That’s exactly what these recipes along with our traditional slime recipes are, a new cool substance!

I hope you have a better understanding of what borax free slime recipes really are! Plus, I hope you have found some unique ideas just behind your kitchen cupboard doors!

These borax free slime ideas can’t be beat when you need a little something different to do on a rainy or snowy afternoon. Plus, there’s a always a little science mixed with the cool sensory play.

Prepare to get slimy! Happy experimenting!
