Mjaeh Frida.. nu er netop whiteboard markers IKKE vandbaserede.. såeh...
Næh, det man skal er at se efter at produktet overholder ASTM D-4236.
Det betyder at det er uden gift også ved indtagelse, samt overholder en række regler m.h.t. grænseværdier..

In the fall of 1992, the Consumer Product Safety Commission (CPSC) came up with their final statement on labeling requirements. The ASTM D-4236 standard was modified as follows:
A substance is a hazard if it is a known or probable human carcinogen, and has a cancer risk of one in one million or more, or is a known or probable neurotoxic or reproductive or developmental toxicant, and if exposure is above a certain defined level (Allowable Daily Intake).
This modification takes into account such things as:
-Chronic health effects in adults and children
-Which chemicals have the potential to cause adverse health effects such as cancer and reproductive maladies
-How much can be absorbed into the body or bioavailability
-Acceptable daily intake levels

Endelig - JOW, som JMS skriver.. Whiteboard Markers (anerkendte mærker) kan anvendes til at "male" på kroppen. De overholder som regel ASTM D-4236 - I hvert fald når det står på forpakningen og pennen. F.eks Staedtler.
Alm. vandbaserede børne tusser er vel egentlig billigere.. Se efter AFTM D-4236
