Hercolyn d (as distinct from plain hercolyn) is a specially deodorised quality of hercolyn primarily useful as a perfumery solvent rather than an aromatic ingredient, although it does still have some residual odour. this material is a very high viscosity, sticky, solvent; pourable but thick and straw-to-pale-amber in colour, with good solubility in ethanol. it has extremely helpful fixative effects and is also useful as a general blender.
