Fabric Softener Reaction

I have one fabric softener which smells nice but it did something I do not expect. I liked it so far. Clothes smell good, there is no static electricity in my artificial wool blouses and ironing is improved. Yesterday I had noticed something. There was some fine scent in one of my blouses I do not like. It was reminding me to vomit. It was vaguely present but I had sensed it. What was interesting is that it was only this particular blouse. Then it came to me. I had used my new perfume on it an hour before placing it in the washing machine. It is the only explanation why it has this faint scent of vomit. It may have happen some chemical reaction. Who knows what kind of organic compounds they are in the washing powder, the softener and the perfume.
