You can read all the details here.Standard Practice for Labeling Art Materials for Chronic Health Hazards). In addition to compliance with European Common Market regulations, Acrylicos Vallejo decided in 2004 to begin the process of obtaining the ASTM D-4236 "No Health Labelling Required" certification for the U.S.A. distribution of their products. For a period of two years formulas for our colors were submitted to a U.S. laboratory, and were found within the safety limits set by the ASTM organization. This is a continuing process, as new formulations arise. For more information please see http://www.astm.org.
The ASTM certification, "Conforms to ASTM D-4236" is commonly accepted as a guarantee that the product is not toxic. However this should not be understood as a warrant to use paint without caution, since any color will contain some level of potentially harmful chemicals. Besides pigment and binder, paint contains many more ingredients and although no immediate or long term health hazards are anticipated with the use of any of these chemicals in the prescribed quantities, long term testing for chronic toxicity has been scant and incomplete. Colors should not be ingested or inhaled, no matter what their pigment content may be.
I'd say that it is a safe bet that this applies to all acrylic paints regardless of manufacturer.
