Are you are talking about carrier oils, without essential oils or a blend of essential oils added to it? I buy organic base oils from healthfood shops and mix up my own using sunflower oil predominently with 2% of either olive oil (cold pressed organic) or sesame oil. As an aromatherapist I customise my own blends to suit.
I did in the past buy sweet almond oil from a company, but now prefer my own blend.
