  • Mixing 2 different types of oils together

    Posted by Michaelv03 on September 13, 2016 at 8:44 am

    Hello,
    I am a novice but have been experimenting with oils for quite some time now.
    I am wondering if there is a way to mix an Essential oil (such as D-Limonene) with a ‘filler’ oil such as Canola oil.
    I have previously tried using alcohol or soaps to get the 2 oils to mix but it did not work (In any case, using soap would not be such a good idea as soap are know to break oily substances apart, correct?). I am not sure why it is suggested on various websites that alcohol can help mix oils together…I never got it to work (or maybe I was doing something wrong).

    I have also tried a product called Sucragel to get the 2 to mix.
    While it did create an emulsion, it was not a good fit for my purposes as the mix needs to remain stable when in contact with water (Sucragel will ‘fall apart’ in water).

    The idea is to create a stable mix of these 2 oils that won’t need shaking, but will remain mixed at normal room temperature. 

    Thank you in advance for any and all help regarding this.

    You have two posts asking the same question.

    What is the purpose of the product containing two oils?

    If you just want to make a dilute essential oil then diproplylene glycol works for most. Alternatively, a cosmetic ester such as isopropyl myristate.

    In the main, glyceride oils such as canola are not miscible with essential oils. An exception is castor oil which has a unique composition which renders it soluble in many essential oils and high proof alcohol. Castor oil is quite viscous which may be advantageous in your product to retard evaporation.

    You might also want to look into PEG-40 Hydrogenated Castor Oil

    Hi Bobzchemist,
    Thanks! I actually just bought some standard Castor Oil at CVS to try it. It seems to work well. It mixes well with D-Limonene for example. Is the type you mentioned (‘PEG-40 Hydrogenated Castor Oil’) the same as the ‘normal’ castor oil you can buy at most drug stores or is there a difference?

    PEG-40 HCO is Castor Oil that has first been hydrogenated, making it a wax, and then reacted with PEG-40, which turns it into a powerful solubilizer and surfactant. 

    If you want your mixture to go into water, you’ll need something like this. Otherwise, like all oils, it will not mix with water at all.
