I just made a new friend and she recently completed chemotherapy for breast cancer. I make home made soaps and I am planning on making an Olive Oil soap for her since I am told it is the most gentle. No fragrance obviously. I would also like to make her a body butter to help combat her dry skin. Obviously I won't be using fragrance in that either and only the highest quality butters and oils. Is there anything I should know that will make sure this product will be safe for her and not an irritant? I plan to use Coco, Mango, Kokum and Shea butters, Coconut Oil, Jojoba Oil and Vitamin E. Should any of those be avoided for her particular situation? Thank you in advance.
