Hi Joe, Welcome to SMF.
I made this soap way back when this thread was started.
As I stated before, my DH rides motorbikes, and he works in a bicycle shop, so he always has grease marks on his jeans.
In the end I used 70% palm and 30% Coconut oil with a zero superfat, this soap wasn't being made to wash any person, just clothes.
To use it, I wet the soap, wet the stain and rub. Rub rub rub. It lathers up some. I leave it for a few minutes while I sort other clothes. Then throw the jeans/whatever in the wash. I wash with cold water. I have never ever ever noticed the smell of kerosene on the clothes. Next time I am going to make these in tubes, so they can be taken out in my handbag. I have small children who always get grubby. Actually I have nearly grown children and they always get grubby too. I just don't follow them around.
As far as the safflower oil, how much in % would you use for this soap? My experience with this soap is that the harder it is, the better. Safflower used in a high amount will make for a soft soap, and most definitely DOS (dreaded orange spots, or rancidity/oxidisation of the oils). Not entirely bad for just a laundry soap but not really good either.
Did anyone else make this soap? Deda? Carebear? Dag?
