But what about different types of oils? If a substance can be separated into its elements, it is a compound. Examples of homogeneous mixtures. As they do not blend, the composition of the mixture is not uniform. The intermixing does not occur due to the difference in nature of both the molecules, the oil molecules are non-polar and hydrophobic while water molecules are polar.

Many common chemicals are homogeneous mixtures. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Oil is a substance that is made up of molecules that are all the same, making it a homogeneous substance. The mixtures in which the components are uniformly distributed throughout the mixture are known as homogeneous mixtures. A heterogeneous mixture in chemistry is one that contains two or more phases.

In fact, CBD oil may actually help to reduce estrogen levels by interacting with the bodys endocannabinoid system. For example, if you want an oil that has a high smoke point ( meaning it can be heated to a high temperature without smoking), then you would need to mix together different types of vegetable oils.
