Route-dependent · ISO 16128

Is Sinapic Acid natural?

It depends. Cinnamic-acid relative abundant in rapeseed/mustard bran; also obtainable by aromatic condensation chemistry.

INCI nameSinapic Acid
CAS530-59-6
FormulaC11H12O5 · 224.21 Da
FunctionSkin Conditioning
FeedstockCommonly recovered from canola/rapeseed and mustard seed meal,…

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.

Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.

How we scored it

C11H12O5 dimethoxy-cinnamic acid; seed-meal extraction keeps natural carbons (1.0); Doebner-type synthesis from syringaldehyde is petrochemical aromatic (0.0).
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Commonly recovered from canola/rapeseed and mustard seed meal, a byproduct of vegetable-oil pressing. Alternatively synthesised from syringaldehyde via chemical condensation, a petrochemical-aromatics route.

In plain English

A plant acid found in rapeseed and mustard seeds, used to condition skin. It can be recovered from seed-processing byproducts or made synthetically, so its natural content varies by supplier.
