Does anybody know what kind of chemicals?

Actually, it's formaldehyde...which is a carcinogenic (cancer-causing) substance. You should always wash your new clothes before you wear them because of the formaldehyde and the excessive dyes used on them. The dyes (like Sudan Black) are also not good for your body because they get stored in the body's fat tissues.

Good question. When you wash clothes in cool water and a mild soap, the bright look and brand new smell stays for a long time. Surprising you got the same result after washing and bleaching jeans.

I have no idea what the stuff is, but it will probably turn out to be something that is carcinogenic, adds calories even when you're only looking at food or makes you glow in the dark.

They use bright colored dyes!!

no clue....
