Year of discovery :

Data not available.

Synthesis route :

Triplal® is synthesized by a Diels-Alder reaction between 2-methyl-1,3-pentadiene and acrolein. A mixture of two enantiomers is obtained.

Synthesis precursor :

Triplal® forms a Schiff base with Methyl Anthranilate, with a still very green smell but fruity and more artificial.

Isomerism :

Triplal® used in perfumery is a mixture of two enantiomers with very similar smells. This is why they are not separated by fractional distillation. Trans-2-cis-6-Nonadienal is a constitutional isomer of Triplal® but has a very different cucumber smell.

Natural availability :

Triplal® is not available in its natural state.

Allergens :

This ingredient does not contain any allergen.

Comments :

The above limits apply to Dimethylcyclohexen-3-ene-1-carbaldehyde (mixed isomers) used individually or in combination. The sum of concentrations of Dimethylcyclohexen-3-ene-1-carbaldehyde isomers should not exceed the maximum concentration levels established by this Standard. This ingredient is part of the Schiff base (Triplal-methyl anthranilate (or Vertosine, Ligantraal, Agrumea) - N°CAS : 68738-99-8) and induces the application of IFRA regulations for 50,9% of the Schiff base usage. Please also refer to the IFRA Annex II for more information

Annexe I :

Some regulated synthetic ingredients are found in nature and in certain proportions in natural ingredients. This presence in nature has to be taken into account when calculating limits of use recommended by the IFRA. In case you do not know these concentrations, you can use the ones estimated by the IFRA.
