T-50 mixed tocopherols – also found as Mixed Tocopherols T50, Natural Vitamin E – “It is a 50% active blend of natural mixed tocopherols isolated from the distillation of soybean oil and concentrated to contain naturally occurring d-alpha, d-beta, d-gamma and d-delta tocopherols. It is blended into an organic non-GMO soybean oil base. Mixed Tocopherols T50 guards against oxidation and extends your product’s shelf life naturally.” Suggested usage is “Raw Ingredients – 0.04 – 0.5%
Formulations – 0.5 – 1.5%”. This is the one you’d add to your oils and other oil soluble ingredients when you get them home to extend their shelf life. I use it at 0.1% or so, but you can go from 0.04% to 0.5%. The INCI for this one is tocopherol.
If you find this version – Mixed Tocopherols 95%, Natural Vitamin E – you’ll want to use less. “It is a 95% active blend of natural mixed tocopherols isolated from the distillation of soybean oil and concentrated to contain naturally occurring d-alpha, d-beta, d-gamma and d-delta tocopherols.” The suggested usage: “Raw Ingredients – 0.02 – 0.25% Formulations – 0.25 – .75%” So if you were to add this to your oils, you would use 0.02% to 0.25% to slow down rancidity, which is half that of the previous entries of T-50. The INCI is Tocopherol.
