Antioxidants for shower oil
I am formulating shower oil with more than 50% of oils. The exact oils are still not chosen, but at the moment we are working with castor, sunflower, soybean and avocado oils.
Can you suggest me the best antioxidant options for my formula? It will be water-free, only the oils, MIPA Laureth Sulfate and Laureth-4. I think for mix of BHT and Rosemary extract, but all of your suggestions are welcome, I need help about the concetrations too.
Thank you in advance!
