That's why I make my own detergent. The FelsNaptha bars smell lightly while I'm making the soap but after the laundry comes out of the washer and dryer, they don't smell like the FN at all....they just smell like cloth.
I have a question for you
@Beekissed: years ago, DH tried using FN, to spot treat clothes. He thought it did a great job & we had been told it was safe. He always did the wash (in the laundry room, with the door closed), because we had used scented laundry products before I learned about MCS. The toxic chemicals, in the fragrances are waxy & no matter how hard he tried, he couldn't get the stink out of the machines.
One day he forgot to close the laundry room door & I got really sick. I couldn't smell it, but DH said the smell of the FN was fairly strong. So, he got rid of it. Problem solved.
That's the invidious thing about MCS.

I have become "nose blind", as you say, Beekissed. There are times I react & can't figure out why I'm reacting. I'll ask DH if he smells anything & he will say, "Oh yeah! A lady just walked into the room with really strong fragrance. I can't smell it. But, it sure does make me sick!
My question, for you Beekissed, is: You said the washed/dried clothes don't smell like FN, just clean cotton.

Do you smell the FN when the clothes are washing & drying in the dryer? We have wanted to make that FN laundry detergent. But we're concerned it would make me sick.
You commented that, "it seems that the folks that insist on wearing perfumes are nose blind and can't detect just how MUCH they wear

So, they use them too liberally." Actually, you nailed it on the head. Research has shown that our smelling receptor sites become desensitized to strong odors over time. I think the personal care product companies capitalize on that - adding chemicals, to their fragrances, that are addictive (like the tobacco industry & Coke do), so people will buy more of their products.
Have you ever walked into a kitchen where the cook is using lots of garlic and gone, "OMG the smell just about knocked me over", and the cook says, "What garlic smell? I don't smell garlic."
@Nyboy, I'm curious. What shampoo do you use on Martha's dogs? I'm guessing unscented.
