go to http://soapgoods.com they have everything you'll need from essential oils to lotion base to shampoo base etc etc. I would suggest getting books on essential oils, some oils are not good for kids and some are not good for people with certain medical conditions like high blood pressure and epilepsy. Be careful when buying oils and make sure that they are 100% pure essential oils and not fragrance oils. Essential oils can be quite costly. The Aromatherapy Bible by Gill Farrer-Halls is a good book as is Aromatherapy Handbook for beauty, hair and skin care by Erich Keller. You are going to need glass vials (not clear) and glass eye droppers to mix your oils in. It can be expensive but it's well worth the initial cost.
