It looks like a group of chemical surfactants that have been formulated to be non toxic. You can call the 1-800 number below for more details but they even say you can eat it and other than blocking you up it won't hurt you.

Sounds pretty safe.

From the Mr. Clean website -
"A recent television broadcast may have raised concerns about an ingredient in Mr. Clean Magic Eraser. Be assured Magic Eraser is completely safe when used according to directions, and poses no health risks or safety concerns.

Here are some facts about the ingredients used in Magic Eraser:

# The ingredients in Magic Eraser have been safely and commonly used for many years in a wide range of household products.

# Formaldehyde is not and has never been an ingredient in Magic Eraser. One ingredient in Magic Eraser (formaldehyde-melamine- sodium bisulfite copolymer) contains the word "formaldehyde" in its chemical name. However, this ingredient is not formaldehyde and poses no health or safety risks. Think of this name like "sodium chloride", which is table salt. Sodium by itself can be dangerous, but sodium chloride - salt - is safe.

# Magic Eraser is considered non-toxic. As with any sponge-like product, when swallowed this product may block the gastrointestinal tract. Therefore, we do advise to keep this product out of the reach of children and pets to avoid accidental ingestion - it is not a toy.

# It is possible that formaldehyde may be present in minute, trace amounts as a result of the manufacturing process. Even then, the amount present is significantly lower than standards established by governmental agencies and trade associations, and is actually less than what is found in indoor air.

# In fact, no ingredients in Magic Eraser are subject to any health-related labeling laws in North America or in the European Union.

Be assured Mr. Clean Magic Eraser is completely safe and poses no health risks or safety concerns when used according to directions.
