The true test of environmental friendliness is the ingredients list, which should specify everything in the soap. If you see ambiguous ingredients, like “fragrance” or “colorant,” it’s possible there are toxic ingredients hidden in those formulas. You can always look for more detail on the soap manufacturer’s website, or simply find a different brand with a more revealing ingredients list. Others may like the gentleness and full disclosure of ingredients. LifeTree does not test on animals or use animal ingredients.
