Tocopherol and Rosemary usage amounts? - Lip Balm

Hi all, 

I am looking for usage amounts for Tocopherol and Rosemary Oleoresin in my lip balm to help prevent it from going rancid. What % should each be at? I'm finding conflicting information online. 

Thanks!

    you can add Tocopherol at 0.2% to 0.3% and Rosemary Oleoresin at 0.05% to 0.1% and you'll be fine.
