Full Title

Full titles differ between systems:

IPC:

Cosmetics or similar toiletry preparations > characterised by the composition > containing organic macromolecular compounds > obtained by reactions other than those involving only carbon-to-carbon unsaturated bonds > Polysiloxanes > containing atoms other than silicon, carbon, oxygen and hydrogen, e.g. dimethicone copolyol phosphate

CPC:

Cosmetics or similar toiletry preparations > characterised by the composition > containing organic macromolecular compounds > obtained by reactions otherwise than those involving only carbon-carbon unsaturated bonds > Polysiloxanes > containing atoms other than silicon, carbon, oxygen and hydrogen, e.g. dimethicone copolyol phosphate

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 2006.
