Why do some micas have a Prop 65 warning?

  • Updated

Titanium Dioxide, a common component used in micas to add opacity and color, carries a Proposition 65 warning in its powdered form. 

While it appears on the Proposition 65 warning list, it only requires a warning when in powdered form. Once the mica that includes titanium dioxide is suspended in a liquid or solid base, like a soap, it no longer requires a Prop 65 warning. Not all micas contain titanium dioxide, so it is important to check the ingredients list on the product details page if your finished product will be a powder.
