Simple Green is a brand of cleaning products produced by Sunshine Makers, Inc. Their best known product is Simple Green All-Purpose Cleaner, which in 2004 totaled sales of at least $5.7 million USD.
It is advertised as an environmentally friendly, non-toxic, and biodegradable cleaner. It received critical attention from environmental safety activists because of the toxicity concerns of 2-butoxyethanol (EGBE), which was in the formula at under 4%. As of 2013 Simple Green all-purpose cleaner removed 2-butoxyethanol, and has a NFPA/HMIS rating of 0/mininal for Health, Fire, reactivity, and Special. The company stands by its safety, stating that it is backed by over $3 million in safety testing.
Simple Green is listed as an approved Surface Washing Agent per the EPA's National Contingency Plan for oil spills since 1990. EPA toxicity testing reports that Menidia beryllina and Mysidopsis bahia survive slightly better in a 1:10 solution of Simple Green/Crude Oil #2/water solution (LC50 8.30ppm-96hrs and 4.40ppm-48hrs, respectively) than in a Crude Oil #2/water solution (LC50 6.50-96hrs and 3.70ppm-48hrs, respectively).
In 2001, Crystal Simple Green was used to clean up an oil spill in the Baltic Sea. In 2005, laboratory testing on rainbow trout indicated that Crystal Simple Green by itself did not affect the survival of rainbow trout adults or larvae. Crude oil #2 did not affect adults but did increase the mortality rate of larvae to 36%. Crystal Simple Green combined with Crude Oil #2 did not affect adults but did increase the mortality rate of larvae to 46%.
