These materials are hexylcinnamaldehyde, 2-methyl-3- (p-tert-butylphenyl) propanal, 2-methyl-3- (p-isopropylphenyl) propanal, 3-(p-tert-butylphenyl) propanal(p-tert-butylphenyl) propanal, and hydroxycitronellal. A few fragrance materials with tricyclodecenyl propionate are being used with alcohol and alcools as cis/trans and stereo-isomeric mixtures as well as with various Cis and Trans and stereoisomers as fragrance materials.
