Laundry detergent

[Ruthiemae]

So I have batch of soap that didn't turn out right so I decided to use it in my laundry detergent I make. I bought some gain type fragrance oil how much should I add to about a gallon of detergent.

I would start at .5 oz and try that. You can always add more if it doesn't seem to be enough.
