Free Tocopherol Consumption of 0.01N cerous sulfate titration solution NMT 1.0mL per
0.1g
Refractive(20℃) 1.494～1.499
Absorbance( 1%
1cm E ) 41.0～45.0 at 284nm
Heavy Metals ≤10mg/kg
Acid Value Consumption of 0.1N sodium hydroxide titration solution NMT 2.0mL
per 1.0g
Lead ≤2mg/kg
Arsenic ≤1mg/kg
Mercury ≤0.1mg/kg
Packaging
20kg,50kg,190kg steel drum, 950kg TOTE, 20000kg tank, or on
customer’s request.
Stability
In contrast to tocopherol, Vitamin E acetate is resistant to heat and
oxygen.However it is sensitive to alkalis, by which it is hydrolyzed, and
strong oxidizing agents. The product can be stored for up to 36 months
in the unopened original containers.
Storage
Store in tightly closed original container, protected from light, in a dry
place. Recommendated storage temperature
