Google the story if you're interested or go to classaction.org and other news sources. I haven't been able to find an update to the story that would tell exactly what is going on with it right now. The news suppposedly first came out last year. I use this cleaner occasionally in diluted form.

A class action alleges Simple Green cleaning products contain ingredients known to cause harm to humans, animals and the environment despite defendant Sunshine Maker’s assurance that its formulas are “non-toxic.”
The 32-page case out of California says consumers who view the “non-toxic” claim on Sunshine Maker’s product labels reasonably expect that the cleaning solutions are safe for humans, pets, and the environment. According to the suit, however, Simple Green products contain various harmful chemicals that have been linked to blurred vision, asphyxiation, dizziness, nausea, skin blisters, muscular twitching, headaches, and irregular heartbeat. Additionally, some ingredients are potential carcinogens, the suit alleges.
The case claims that by falsely labeling its products as “non-toxic,” the defendant has sought to capitalize on consumers’ desire for safe cleaning products that do not contain harsh chemicals.
As a result of its alleged “greenwash[ing]” scheme, Sunshine Makers has harmed both consumers and its competitors, “over whom Defendant maintains an unfair competitive advantage,” the suit alleges.
