  • Essential oil and water emulsion.

    Posted by Anonymous on January 7, 2014 at 11:21 am

    When mixing Essential oil, water and an emulsifier I am getting a milky white color substance which is what I am looking for.
    However, after the substance is sitting for several hours, there is a separation and 2 layers are formed (or at least it’s simply becoming more visible)
    Is there any way to make this substance homogenous so that it will not split OR at least wouldn’t appear as 2 layers but rather just a unified white substance?
    Thx for your help!

    Without knowing your formulation I can suggest you some extra thickener like carbomer or xanthan or any other commonly used thickener. Depends which essential oil you are using, also if you dont need additional thickener then you have to choose the right emulsifier, probably the one you have chosen cannot handle your essential oil. Try increasing or replacing with something stronger.Also what kind of application properties you are looking for, heavy, light or medium. You need a cream, lotion or gel like consistency.

    1% essential oil.

    I presume this is a room/linen spray so my comments are geared towards that.
    You will need to add a preservative - preservative choices here - http://makingskincare.com/preservatives/

    As a solubilizer, try polysorbate 20 at 12% and if that doesn’t do it keep increasing the % until it does solubilise (different essential oils/combinations need different amounts of poly).

    And just the EO and water or any other component as well?
