The mystery white pastel issue is solved:

The people at Blick got back to me (!!!).  Long story short, the white in the Blick square pastels is Titanium White; the CL is there because they’re concerned about nanoparticles.

Pastels use a larger particle size than that found in mineral sunscreens (which is where the data about exposure is coming from).  Though unlikely, there’s enough of a chance of nanoparticles being in the Blick square pastels that the Caution Label is placed on the product.  Nanoparticles of Titanium Dioxide are transparent; can be absorbed transdermally; and can be harmful if inhaled.  Washing regularly during and after using these pastels should minimize any transdermal absorption.  Gloves are recommended if there are cuts or sores on the hands…the other precautions, I already take:

  • don’t eat or drink in the same area as you’re working, or with dirty hands
  • don’t blow pastel dust up into the air (tap it off of your image)
  • use an air purifier if you will be working for long periods of time

In addition, I’d add this:

  • if possible, wet-mop up any dust, instead of using a vacuum
  • if you use a vacuum, use one with a HEPA filter
  • if concerned, wear a dust mask to trap particles before they get to your lungs (though if nanoparticles are an issue, a respirator might be a better option).

I feel so much friggin’ better, now.  I can actually use these.

I felt the need to update this because of speculations posted earlier (which now seem unfair), and not being able to find this information anywhere else online.  Nor has anyone in any store had this information to give to me (I’ve asked in multiple places, before).

Thank you, kind person from Blick!  🙂
