Well, a true lotion contains water and oils and because it contains water, it must have a preservative. There are paraben free preservatives out there and most preservatives are used at less than 1% of the total formula but you still have to have a preservative or products with water will grow mold, yeast and bacteria among other things.
Additionally, because water and oil don't mix, you have to have an emulsifier so that will be one other not so natural ingredient.
Other than the emulsifier and preservative which make up about 4-5% of a product, you should easily be able to find WAHMs who make lotions which have no other chemicals. Also, many WAHMs are more than happy to do custom orders if you want certain scents etc...
As far as making a true lotion yourself, it may be a little hard to do unless you want to get emulsifiers and preservatives.
But, you can use just oil or oils and butters plus your EO to create a moisturizer.
