We are very economical about our son's soap. We mix it up. He uses sesame street and also Lush brand products as these are very close to organic.
I realize I am posting this after the fact and what caught my eye was how you feel about "green". Green is different that 'organic'. You should be able to pronounce and recognize the ingredients in the product if is it safe for all (environment, body, etc.). Products at Lush are actually Vegan (all vegetable and plant based.) with only the safe preservatives found in cosmetics that have been used for years. The products also have a shorter shelf-life of about a year or less depending on your purchase.
You can go 'green' and still know that the product you are purchasing is safe. Especially if you are very familiar with essential oils, carrier bases (oils and soaps) and all the latin words they are printed under. Just know that some brands claim organic and are not. It still is a buyer-beware market but that is what is so wonderful about hearing from others about their experiences with products.
After reading some responses from another:
Some plants can be toxic, but did you know that what you put on your skin also is absorbed into your blood stream? In a few of my classes on essential oils: 'Never put anything on your skin you could not or would not eat'; soap and cosmetic products included.
Good Luck!
