Our Naturally White Soap Wash For Horses & Hounds - Is hand-made and is 100% natural. The base plant oils are sunflower oil, olive oil and coconut oil with added finely ground NZ organic volcanic pumice and gold certified essential plant oils. We do not use chemicals, alcohol or preservatives. Due to the soaps high pH balance we do not have to add in chemical preservatives. We also lovingly make these soaps in small quality batches by hand and not by machines! So there is no problem with shelf life or cheap undisclosed commercial ingredients.
