Attention!

Before purchasing, read all information below and the general product information.
Not intended for use in food, vape liquids or other internal use.
Intended to be mixed with other fragrances: on its own, the scent can be boring or even unpleasant.
Do not use undiluted on the skin: it is a raw material, not a final product.

Use

alfa Irone has a powdery iris scent. The scent is medium strong, so dilution is not necessary. Typical use is in iris and wood accords. You usually use between 0,1% and 1% of this substance in the fragrance composition, but that is mainly because of the high price. There is basically no reason why you would not use 10%, or more. It goes well with floral scents such as rose and violet and with fruity scents such as blackcurrant, raspberry and plum. It is mainly a base note in perfumes and is also stable in soap. It is less stable in very acidic products.

A frequently recurring question is whether alpha Irone cannot simply be replaced by ionones. The scents are indeed very similar and in many cases considerably cheaper ionones can be used. However, for a more experienced perfumer it can make a difference. The diffusion of alpha Irone is better than that of ionones, which means that special effects can be achieved. However, experience is required for this.
