Certain products on this site require MSDS Sheets. They can be found a on a link at the bottom of the product information section under the heading "Additional Information."

Labeling of Hazardous Materials

EnvironMolds, LLC has strived to offer environmentally friendly as well as artist safe materials. However, there are certain materials artists must use that are considered hazardous. In those cases we strive to inform our artists, teachers, and consumers about potential hazards in the arts. We go to great lengths to advise how to handle such materials properly.

EnvironMolds, LLC utilizes two great third-party sources to advise us on materials safety. They first is a California-based lab, Info Tox. International, Inc. The second is ACMI.

The Art and Creative Materials Institute (ACMI) is a non-profit trade association of art and craft materials manufacturers. Since 1940, ACMI has conducted a certification program in which product formulas are analyzed by a renowned toxicologist and certified by ACMI as non-toxic or properly labeled. ACMI certification also ensures compliance to state and federal labeling regulations.


Products bearing the APPROVED seal have been examined by Info Tox. International, Inc. and have been evaluated to conform to the labeling standard ASTM D-4236 and federal law P.L. 100-69.The materials have been reviewed by a toxicology expert the ingredients have been deemed to be material is non toxic for humans. All of ArtMolds' SILFREE alginate formulas are non toxic.

AP Symbol

Products bearing the AP seal of the Art & Creative Materials Institute, Inc. (ACMI) are certified non-toxic. A medical expert evaluates each product and its ingredients. A product can be certified non-toxic only if it contains no materials in sufficient quantities to be toxic or injurious to humans, or to cause acute or chronic health problems. AP certification is reviewed by ACMI's Toxicological Advisory Board. These products are certified by ACMI to be labeled in accordance with the chronic hazard labeling standard, ASTM D-4236 and federal law P.L. 100-695.

EnvironMolds suggests that when you purchase art materials, particularly for classroom and institutional use, you should carefully consider the ultimate consumer. In cases where a product may be used in pre-school or primary school classes (K-6), or in environments with physically or mentally challenged persons who may be unable to read or understand safety labeling, you should purchase materials which are AP certified non-toxic products. This will ensure that even the most sensitive populations can safely enjoy art and craft activities.

CL Symbol

Products bearing the CL seal of the Art & Creative Materials Institute ("Caution Label") contain ingredients that are toxic or hazardous, but they can be used safely with appropriate caution. Materials that bear the CL seal should be used only by those persons who are able to read, understand, and follow suggested safety precautions for handling those materials. The Caution Label signifies that although the product contains a toxic element, it can be handled safely if the directions on the container or packaging are followed. Many such art products cannot be made non-hazardous, but are necessary for certain creative activities. When used in properly supervised and controlled conditions, they can be enjoyed with complete safety.

Info Tox. International, Inc. and ACMI labeling indicates that a product has passed through a vigorous review process. The absence of caution labels does not indicate that a product is safe for use by children. Please read all labels and instructions before using art materials. Be an informed customer. We try to inform our customers of important health and safety issues, and we invite your comments on this issue.

Additional Health Labeling: California Proposition 65

Prop 65

The State of California requires clear and reasonable warnings on products and/or storage containers containing chemicals that have been shown to cause cancer, birth defects, or other reproductive harm. Even if these products contain only trace levels of harmful chemicals, a warning is required by the State of California. Manufacturers of certain products have included warnings pursuant to California Proposition 65, and caution is recommended when using products marked with the Prop 65 icon.
