I've been making my own detergent for at least 2 years. I make the liquid version - 5 gal. at a time. I pour it up in empty detergent bottles that I get from my friends. I give half of what I make to my dear friend. She washes more than I do. My daughter also makes the liquid version but objected to the Fels Naptha soap smell so she substitutes Ivory soap and it works the same. Zote is real soap just like Fels and/or Ivory and the only bar I saw was pink. I guess I was out of my mind at one time and ordered TWO cases of Fels Naptha soap so I have a lifetime supply. I'll never know what made me order that much soap. I have added some of the fragrance crystals but it seems to make the consistency of the detergent change.
