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 extraction | Apple (Malus) bark/root extraction | 1.00 | ~30% | |
| Chemical synthesis | Aromatic condensation (phloroglucinol/hydroxybenzaldehyde types) + hydrogenation | 0.00 | ~70% |
How we scored it
Where it comes from
Dominant commercial route is believed to be chemical synthesis (condensation of phloroacetophenone-type and hydroxybenzaldehyde-type aromatics, then hydrogenation) for cost and purity. A natural-extraction route from apple tree bark/root also exists as a specialty ingredient.
In plain English
An antioxidant compound related to those found in apples, used in anti-ageing serums. It can be extracted from apple tree bark and roots, but much cosmetic-grade material is made by chemical synthesis.
