Absolutely. Rainbow Mulch is made of 100% naturally-derived ingredients: raw rubber, earth, zinc, baking soda, sulfur and fatty acid. This mixture is completely non-toxic and contains no wires, tires or other filler.
Additionally, Rainbow Mulch has been tested for fall protection and meets ASTM standards F1148, F1487, F1292 and F1918. This means that Rainbow Mulch is a great option for playgrounds, daycares, churches and civic parks.
A division of the California Envrionmental Protection Agency, the Office of Environmental Health Hazard Assessment, tested skin sensitization of rubber mulch and found it did not increase skin sensitivity in children who displayed no prior reaction to latex or rubber materials.
