| Hazard Information | Back Directory | [Chemical Properties]
3,7-Dimethyl-1-octanol has a sweet, rosy odor and bitter tas | [Chemical Properties]
Clear colorless liquid | [Chemical Properties]
Tetrahydrogeraniol has been identified
in citrus oils and is a colorless liquid with a waxy, rose-petal-like odor. It is
prepared by hydrogenation of geraniol or citronellol in the presence of a nickel
catalyst and is a by-product in the synthesis of citronellol from geraniol or nerol.
Because of its stability, it is often used to perfume household products. | [Uses]
3,7-Dimethyl-1-octanol was employed as medium supplement in the anaerobic enrichment cultures of Pseudomonas citronellolis.2 | [Preparation]
Usually prepared by hydrogenation of geraniol, citronellol or citronellal. | [Production Methods]
3,7-Dimethyl-1-octanol is commercially produced by the
reduction of geraniol or by the reduction of citronellol,
citronellal, or citral. It is used in fragrances and in
foods. | [Aroma threshold values]
Aroma characteristics at 1%: fresh fatty, waxy, soapy, aldehydic citrus with lemon, lime and orange
nuances. It has rosy and green woody notes | [Taste threshold values]
Taste characteristics at 1 to 10 ppm: fatty, waxy, soapy with floral rosy and fresh citrus-woody nuances.
Natural occurrence: Reported found in lemon, lemon peel oil and thyme; corresponds to the dl-form of dihydro-citronellol. | [General Description]
3,7-Dimethyl-1-octanol is an fragrance ingredient and its toxicologic and dermatologic review as a fragrance ingredient was reported. | [Flammability and Explosibility]
Nonflammable(100%) |
