Melamine

[Langbein]

We have it in the kitchen and maybe the bed, but might not want more.

What is it really, something healthy or possibly the opposite???

Melamine is used in many other things as well, but from what I can find - after some quick searches here and there, the preparation used as a surface layer doesn't have major concerns; there are no known effects upon close contact (like irritation, allergy or similar). There are certain preparations of melamine classified as "may possibly cause cancer," meaning no strong evidence - based on animal experiments. There are also some animal studies indicating that melamine can cause bladder stones (when ingested in food), but there are no definite studies on humans.

Of all the possible and impossible organic and inorganic materials, melamine in the forms we use indoors doesn't seem to be a significant problem. However, I emphasize that I am not an expert in this area, and there are other sources that can surely provide you with exact answers.

Best regards, hanneli (who is NOW going on vacation! - without broadband...)

Yeah, I have found about the same:

MELAMINE doesn't exactly seem to be health-promoting:

Regardless of whether the effect is direct or indirect, the occurrence of
tumors in male rats after being treated with melamine is considered a cause
for concern for workers or consumers who are exposed to melamine.

It can apparently migrate from kitchenware too.
I don't have time to read and analyze everything, what more?

Good evening,

I am now clearing the thread of content that does not pertain to melanin. If we want to discuss melanin, we do it in this thread; if not, we let it fade away.

Furthermore, this forum is not a place on the Internet where one can "blurt things out" haphazardly. For everyone's comfort, each is requested to follow the forum's rules and behave as gentlemen -and women.
