Problems with aroma in an oil-based scrub

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?
