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

Isobutavan (Giv) has a sweet, spicy scent reminiscent of chocolate and vanilla. The scent is not particularly strong, undiluted use is common. Typical use is in gourmand accords, especially of caramel and chocolate. You usually use between 0,1% and 5% of this substance in the fragrance composition. It is very versatile, just like vanillin, it fits in amber, wood, fruit but also in various floral scents such as honeysuckle. It adds a kind of creaminess to the scent. In perfumes it is mainly a base note, it is stable in most products. In soap it discolours less easily and quickly than for example vanillin and ethyl vanillin.

Store in a cool, dry, dark place and out of reach of children.
