Absolute Oils are highly concentrated essences obtained from plant parts. They are much more difficult to extract and the method of extraction is very complicated. Used extensively in perfumery, the aroma obtained from an Absolute Oil is closer to the original plant product than the aroma from Essential Oils produced through distillation. Because the Absolute Oils are highly concentrated, very little goes a long way. Absolutes are also quite expensive to produce because the plant parts used for producing them usually contain very little oil. For example, it requires more than 30 roses to produce 1 drop of Rose Absolute Oil.
