Route-dependent · ISO 16128

Is Lauraldehyde natural?

It depends. The C12 chain is either the coconut or palm kernel lauric chain or ethylene-derived undecene plus synthesis-gas carbon, and the two feedstocks give opposite values.

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.

RouteFeedstockNOIShareNotes
Oleochemical: dehydrogenation of lauryl alcohol or lauric acid with formic acidCoconut or palm kernel lauric oil1.00about half (estimate)
Hydroformylation of 1-undeceneEthylene-derived 1-undecene plus synthesis gas (petrochemical)0.00about half (estimate)
Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.

How we scored it

C12H24O, 184.32 Da. Oleochemical route: lauric C12 chain, 184.32 / 184.32 = 1.00. Petrochemical hydroformylation of 1-undecene: 0 / 184.32 = 0.00. Routes are not averaged.
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

Dominant route cannot be determined: fatty-alcohol dehydrogenation (coconut or palm kernel) and 1-undecene hydroformylation are both used for fragrance-grade dodecanal. Trace amounts also occur in citrus and coriander oils, and natural-grade material is sold.

In plain English

A fatty aldehyde with a waxy, soapy, citrus-like aroma, used as a fragrance ingredient. It is made either from lauryl alcohol of coconut or palm kernel oil or built from petrochemical alkenes, and suppliers use both routes.
