  • Problems with aroma in an oil-based scrub

    Posted by AleH on January 9, 2020 at 12:50 pm

    Hi! I’m looking for some advice as I formulated oil-based all-natural body scrub with a very subtle smell in the beginning but after a week it smells stronger and not so pleasant.
    I don’t know if it’s because of microbiological contamination, but there’s no water and I supposed Naticide would make a little work to avoid that.
    Or could it be that oils are getting rancid in a week and tocopherol is not enough?
    It is supposed to last at least 6 months but something is going in a bad way…
    Here there’s the formula:

    Simmondsia
    Chinensis Seed Oil
    12
    Macadamia Ternifolia Seed Oil 5
    Anigozanthus flavidus (Kangaroo
    flower)(and) Helianthus annuus 
    6
    Terminalia ferdinandiana (Kakadu plum)
    Seed Oil
    5
    Cocos Nucifera (Coconut) Oil 8
    Butyrospermum Parkii (Shea) Butter 7
    Cetearyl Olivate, Sorbitan Olivate
    (olivem 1000)
    3
    Pumice powder 5
    Coconut CO2 Extract 1
    Tocopherol 2
    Salt 4,5
    Kaolin 40
    Mica 0,5
    Naticide 1

    I would appreciate very much your comments! Thanks!

    A couple of things here. Some of your oils are prone to rancidity and I see you used tocopherol, however, 2% might act as pro-oxidant. It’s too high, I advise to reduce it to 0.1%
    Another possibility is that your kaolin wasn’t dry enough.

    Thanks @ngarayeva001! Sure, I thought the higher the tocopherol the better, but make sense! I will try to reduce it! 
    Any advice on other natural antioxidants?
