Borax is used in the making of Coco Slimes in a very diluted form. Please check out our post "What's in Slime? Atoms, Molecules, and Science!" to see why borax is needed in the making of slimes.
Many people are concerned about Borax have read misleading health articles online and confused Borax with Boric Acid.
While Borax is a naturally occurring mineral (It is sold in supermarket as an environmental friendly household cleaner, like Bicarbonate of Soda), boric acid is a weak acid used mostly as a pesticide.
At Coco Slimes, we use 20 Mule Team Borax which is the household safe Borax! Coco Slimes is safe to play!
Although safe, be sure not to ingest and always wash your hands and your table after playing with slimes!
