  • Honey and Oil Facemask Preservative + emulsifier?

    Posted by Anonymous on January 3, 2020 at 5:08 am

    Hi,

    I am wanting to formulate a honey and oil containing facemask. There will not be water in this product. For this, I understand that as there is no water I should not need a preservative but I want to add a preservative due to storing this product in the bathroom and can generally get wet. Now, if I add an oil-soluble preservative do I need to emulsify the oil and honey together? If so what emulsifiers are good to emulsify the oil and honey together?

    what emulsifiers are good to emulsify the oil and honey together” what are you going to emulsify if, as you say, there is no water? If there is no water they should just mix together, aren’t they?

    Honey is water-soluble, so just treat it like it was your water phase and use any appropriate emulsifier for the type of emulsion you are trying to create … O/W or W/O.

    Also honey is a significant challenge for the preservation system.

    Not that much of a challenge if there’s no water present. Sure, honey is hygroscopic and might absorb water over time. Assuming it’s going to be a honey in oil emulsion, this effect is minor and therefore preservation is more of a ‘better safe than sorry’.
    Regarding emulsifiers: Unfortunately, HLB considerations won’t work with pure honey as ‘aqueous’ phase… I guess it all comes down to trial and error.

    for what it’s worth, honey is about 80% sugar, about 20% water and miscellaneous trace compounds
