Is Benzylidene Sorbitol natural?

Mostly. Sorbitol from hydrogenated glucose is natural, while benzaldehyde, made industrially by oxidising toluene, is petrochemical and loses its oxygen as water on acetal formation.

How we scored it

Assumed mono-benzylidene C13H18O6 270.3: sorbitol-derived C6H12O6 180.2 natural; benzylidene C7H6 90.1 petrochemical (toluene-derived benzaldehyde); 180.2/270.3 = 0.67.
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: acid-catalysed acetalisation of sorbitol (from corn or wheat glucose) with toluene-derived benzaldehyde. Alternative: natural benzaldehyde from cassia or almond is possible but not commercially significant here.

In plain English

A sugar-alcohol derivative that thickens or gels liquids. It is formed by joining sorbitol, made from glucose, with benzaldehyde. The sorbitol is plant-derived; benzaldehyde is mostly made from petrochemical toluene.
