Other names :
2,2-dimethyl-3-(3-methylphenyl) propanol ; 2,2-dimethyl-3-(3-methylphenyl) propan-1-ol ; 3-(2,2-dimethyl-3-hydroxypropyl)toluol ; Lanjantol ; Lilivol ; Lily propanol ; Linlan alcohol ; Muguenol ; Trimethyl benzene propanol ; Trimethylbenzenepropanol
Volatility :
Heart
Uses in perfumery :
Majantol® enters the floral-aldehydic molecules category, including Lilial® and Bourgeonal® for example. It is used as it is slightly less regulated, for lily of the valley and other white flower notes, for a light effect, in association with other molecules as Hedione® or Florol®. It also brings a fresh nuance.
Natural availability :
Majantol® is not reported as found in nature, and can thus not be extracted from any plant.
Year of discovery :
Patent N°3,531,585 (DE) published on Sept. 4, 1985 by Elektrochemisch Industrie GmbH
Other comments :
Majantol® structure is close to Dimethyl Benzyl Carbinol. Its smell is less aldehydic and aqueous. Majantol® also has olfactive similarities with Lyal® and Hydroxycitronellal®, although it is more aqueous than theses molecules.
Price Range :
€€
Stability :
Aromatic compounds are chromophorous. This means that they may color through time and in contact with alkaline bases.

Synthesis route :
Majantol® can be prepared in two steps, starting with 3-methylbenzyl chloride, reacting it with 2-methylpropanal, in the presence of a catalysor as tetrabutylammonium iodide. An aldehyde is obtained and can be reducted, reacting with sodium tetrahydruroborate, to obtain the final product.
Synthesis precursor :
Majantol® is not a precursor for the synthesis of another material used in perfumery.
Isomerism :
Majantol® has a methyl group associated to carbon n°3 of its aromatic cycle, on a meta position. Molecules having this groupment on an ortho or para position are not used in perfumery, although they are isomers of Majantol®
Phenoxanol® is a constitutional isomer of Majantol®, having a more rosy and green note.

- Comments :
- Benzyl cyanide as such should not be used as fragrance ingredient. The natural extracts containing Benzyl cyanide should not be used as substitutes for this substance. On the basis of established maximum concentration levels of this substance in commercially available natural sources (like essential oils and extracts), exposure to this substance from the use of these oils and extracts is not significant and the use of these oils is authorized as long as the level of Benzyl cyanide in the finished product does not exceed 0.01% (100 ppm).
