Why the score varies
This ingredient is made commercially by more than one route, and ISO 16128 scores the feedstock actually used. Without a supplier certificate of origin the value cannot be claimed.
| Route | Feedstock | NOI | Share | Notes |
|---|---|---|---|---|
| natural d-alpha-tocopherol esterified | vegetable oil (soy/sunflower) tocopherol + synthetic nicotinic acid | 0.80 | ~35% | |
| synthetic dl-alpha-tocopherol esterified | petrochemical trimethylhydroquinone + isophytol, plus synthetic nicotinic acid | 0.00 | ~65% |
How we scored it
Where it comes from
Tocopheryl Nicotinate is made by esterifying tocopherol (vitamin E) with nicotinic acid; the nicotinic acid is manufactured from petrochemical 3-picoline/3-cyanopyridine regardless of source. The tocopherol portion may be natural vegetable-oil-derived d-alpha-tocopherol or fully synthetic dl-alpha-tocopherol depending on supplier.
In plain English
A form of Vitamin E combined with niacin (vitamin B3), used to condition and protect skin. The vitamin E portion may come from vegetable oils or be made synthetically; the niacin part is always manufactured chemically.
