I would really appreciate it if you could tell me what type of vitamin E to use to slow the oxidation of essential oils, as in cream. Is it just tocopherol? Or some other type?

Thank you for your time.

PS. I enjoyed your webinar very much!

Hi Stephanie,

There are four principal isomers (chemical subtypes) of tocopherol:


There are also sub-types of each one.

You can use ‘mixed’ tocopherols: all four in various proportions. But my preference for essential oils is to use alpha-tocopherol, specifically d-alpha tocopherol. Here is a supplier that sells small quantities, as well as large.
 Because it is very viscous, you may want to mix it 50/50 with a fatty oil or essential oil before adding to your product. You don’t need much – the tocopherol should be added at 0.1% by weight of the total product. Putting more in won’t be more effective.

Although ‘tocopherol’ and ‘vitamin E’ are often used synonymously, vitamin E is actually even broader, because the term encompasses both tocopherols and tocotrienols.
