Re: [ARSCLIST] Fact or fiction: Sharpies damage cd-r?
I had heard that they were water-based, too, but turns out they aren't.
A while back, I requested and received the Material Data Safety Sheets
from Sanford for their regular Sharpie Fine markers, and their Sharpie
CD markers. Actually, what I requested was their evidence that the CD
markers were safe for CDs, but this is what I got.
In addition to dyes, the "regular" markers contain n-propanol (71-23-8),
n-butanol (71-36-3), and diacetone alcohol (123-42-2).
The "CD/DVD" markers, on the other hand, contain dyes, ethanol (64-17-5)
and 1-methoxy-2-propanol (107-98-2).
Not being any expert on chemistry, I took this to mean that the CD/DVD
markers still contain alcohol, just a different type of alcohol. I'm
sticking to writing on the outside of the jewel cases instead.

Just to muddy the waters a bit, Sanford, the maker of Sharpies, now
Sharpie "specially formulated to write safely on cd's and DVD's."
