Resinoids are extracts of resinous plant exudates (balsams, OAKMOSS, ladanum,galbanum,and natural oleoresins) and animal secretions (ambergris, castoreum, musk, and civet) that are extracted with solvents such as methanol, ethanol, toluene, or acetone. Yields range from 50 to 95%. The products mainly consist of nonvolatile, resinous compounds.
They are usually highly viscous and are sometimes diluted (with phthalates or benzyl benzoate) to improve their flow and processing properties.Resinoids are mainly used as perfume fixatives.
