I am not sure. lol. When my kids were babies I used Borateam (sp) and Ivory. Then I switched to Tide and used it forever but the cost didn't really start to jump for along time. Then they started adding all the perfumes to everything and I am strange I guess. I want my cloths and bedding to smell clean, not like some flower. When the cost got outrageous I went to Arm & Hammer and it was logical to me since I have been using their other products for years. And I am happy with it.
