What is Borax?

Borax is also known as sodium borate and is an important boron compound, a mineral and a salt of boric acid. The powder is white and it dissolves in water.  It is a component of many detergents, cosmetics and enamel glazes.

In the United States it is banned as a food additive and indicated with the “E number” E285.  China and Thailand have also banned its use in food due to a risk of liver cancer with high consumption over a period of 5-10 years (see Wikipedia for more information).

Is Borax Safe to Use in Slime Recipes?

Researching the negative effects of Borax results in multiple issues that can occur.  The most toxic include skin, eye, respiratory irritation, diarrhea, vomiting and cramps with occasional exposure.  As noted above, when exposed over long periods of time in food, liver cancer is also a risk.  And if you have a child that likes to put things in their mouth, then avoiding Borax is a no-brainer!

Since we don’t love subjecting our kids to anything toxic, especially in a slime recipe, it was important to us to find alternatives that still made amazingly awesome slime!

Borax Can Cause Burns With Repeated Exposure

Borax is a milt irritant.  As with any irritant, some people (and kids) will be more sensitive to it than others.  Our main goal here is to inform so you are choosing the best thing for your family and noting any reactions.

In slime, the Borax is very diluted and rarely causes issues…but why take the risk?

Is Slime Toxic?

There are many ways to make slime without Borax.  Although Borax is used to create a sticky texture, there are other (and safer) ways to make slime.  If you do choose to make slime with Borax, watch your kids for side effects like skin, eye, respiratory irritation, diarrhea, vomiting and cramps.  Make sure that younger kids are not consuming slime.  We have a lot of edible play dough recipes if that is an issue in your house!

Because the other ingredients in slime are usually food-based like food coloring and other kitchen ingredients, they are generally considered safe for slime recipes as well.  White glue has long been used with kids crafts and projects and in the classroom and isn’t known to have toxic ingredients.

What About Contact Solution…isn’t that Just Borax too?

Yes and no.  Contact solution has a trace amount of boric acid.  But it is used in contact solution which is used in contact with the eye.  It is regulated by the FDA here in the United States and since it is used in small quantities and very diluted in slime, it is considered a Borax-free solution to making slime.

Borax-free Slime Actually Contains Borax?

Contact solution is a common choice for making Borax-free slime.  It has trace amounts of boric acid which is an ingredient in Borax.  So, kinda!  Yes, Borax-free slime actually has trace amounts of ingredients found in Borax.  But…think about the concentration of boric acid and how contact solution is used.  The main objection to using Borax in slime is the irritation it can cause with repeated touch.

Because contact solution is used in the eye and regulated by the FDA, it is considered a safer alternative to Borax.  If you truly want to make slime without any boric acid, check out the recipes that use a combination of glue and baking soda instead.
