Well, that was easy! But wait! I skipped over the best bits, the bits where you customize the oil and butter, choose your cute packaging, and create your own fragrance!
When making bath & body things, always ask yourself "what's my goal is for this product?" For solid perfume, we want a nice smelling lotion bar that melts on contact with our skin.
Meaning that if you choose sunflower oil, you'll have six months. Olive oil - a year. Grapeseed oil - three months at best. This is a big deal. No one wants a rancid perfume! Ick!
If you choose fractionated coconut oil, coconut oil, and shea butter, you have a one year shelf life. The butters have about 2 years. Coconut oil a year or so.
Choosing oils is important and I only have so much space, so please visit http://swiftcraftymonkey.blogspot.ca/p/oil-butter-posts.html for loads of information on oils and butters.
Anna Rose suggested this combination: 2 parts rose otto and 1 part citrus.
Jane suggests Spice Cookie: 3 parts vanilla, 1 part cinnamon, 1 part benzoin. (Use at no more than 1.5% by weight.) Combine with cocoa butter for chocolate goodness.
To summarize: Weigh your ingredients. Heat. Remove from the heat. Add fragrance oil. Mix. Pour into tube, tub, or jar and let set. (Put it into the fridge if you want.) Apply. Rejoice!
