Helional is also called “Piperonal”. In many books introducing spices and essences, the aroma of jasminal is described as the so-called. The “sunflower” aroma of Helional, in fact, the aroma of Helional should be a bean aroma with fennel flavor, which has nothing to do with the “floral fragrance”. This spice is also more prone to discoloration, especially if it encounters a small amount of indole, it will also turn pink, so you need to pay attention. In soap essence, bean fragrance is very important, coumarin is the “first” because of its cheap price and no risk of discoloration, but the aroma of coumarin is “too monotonous”, adding some jasmonal will make it A kind of “exotic flavor” (the so-called “foreign flavor”) is more able to touch the hearts of consumers. When Helional is added in a large amount, especially when there are nitro musks (musk sunflower, dimethyl, musk benzene, and musk ketone, etc., it is best to add some geraniol to make the produced look stable.

Helional is obtained by using jasminal as raw material, first condensing with propionaldehyde, and then selective catalytic hydrogenation.

In the “classification of spices”, no one will put it in any group of spices other than “green fragrance”. Once the aroma of privet aldehyde is exposed, it will give people a “pungent” feeling. At this time, it is best to add other green fragrances such as citrus aldehyde, leaf alcohol, leaf acetate, salicylate, sevita, and cyanin , linalool, olive green ketone, phenylacetaldehyde, watermelon aldehyde, etc. make the head fragrance less “pungent”
Citrus aldehyde has a higher aroma ratio, but it is not as “sharp” as privetal, and it can also “shave off” the “sharp-thorny” smell of privetal. Therefore, whenever privet aldehyde is used in the essence, almost 3 to 10 times the amount of citrus green pendant will be added. Green aldehyde is the “peacemaker” of many green fragrances, and it is found in most green fragrances. It’s “shadow”.
