To help you find ingredients with the odour characteristics you’re looking for, every ingredient is tagged with a set of descriptors.
Use the drop-down menu in the sidebar (possibly below if you’re on a mobile) to select an odour descriptor to see all the products that are tagged with that descriptor. These tags are used only for ingredients, so you won’t find fine fragrances through this route. Alternatively explore the tag cloud below: you can zoom in and out to see more or less detail and keeping your cursor near the centre of the cloud will slow down the movement, nearer the edge will speed it up.
Each ingredient product also has a list of the categories it’s in and the odour descriptors it’s tagged with included in its description and these are clickable links so you can easily list everything else in the category or with any of the odour tags from there.
