I have a little knowledge of chemistry.
I was talking to a sales rep from a cleaning supplies company. They sell a scrub sponge that looks and functions just like Mr. Clean Magic Eraser. The sales rep was trying to scare me by saying that magic erasers have formaldehyde.
I know that the properties of a chemical compound are different than the properties of each component. I suspected that their product is actually the same as the magic eraser so I contacted the company directly, but got a less than satisfactory answer.
I asked if their sponge was made of formaldehyde-melamine-sodium bisulfite copolymer. They did not answer yes or no. They told me their sponge is made of melamine resin.
According to Wikipedia, melamine foam (a foam-like material consisting of a formaldehyde-melamine-sodium bisulfite copolymer) is a special form of melamine resin that is used mainly as an insulating and soundproofing material and more recently as a cleaning abrasive.
I would like to be more knowledgeable next time this sales rep contacts me. Hence the question.
Is there another way to make an abrasive foam sponge out of melamine resin that is not formaldehyde-melamine-sodium bisulfite copolymer? Is there a way to make a melamine resin without using formaldehyde?
