Description
Lauryl acetate has a characteristic citrus-rose odor. The corre sponding flavor develops only on dilution. May be prepared by
acetylation of lauryl alcohol.
Chemical Properties
Lauryl acetate has a characteristic citrus–rose odor. The corresponding flavor develops only on dilution.
Occurrence
Reported found in sour cherry, cardamom, bitter orange, lime, lemon and mandarin peel oils.
Uses
1-Dodecanol Acetate can be used as a foaming agent in the purification process of quartz sand. Furthermore, it is a main component of the essential oil from the flowers of Etlingera elatior (Jack) R. M. Smith, which is found to be active against Staphylococcus aureus, Bacillus cereus, Candida albicans and Cryptococcus neoformans.
Definition
ChEBI: Dodecyl acetate is a carboxylic ester.
Application
Dodecyl acetate is useful in perfume formulations, particularly as a topnote ingredient - in spite of its high boiling point. In fact, the performance of odor, shown by this chemical, is quite remarkable. A lasting odor from the very topnote throughout the various stages of evaporation of the fragrance. However, it needs blending with other materials to become more attractive, especially Citrus oils, light, fruity notes or light woody notes. It will also impart a pleasant freshness to sophisticated Pine fragrances, and in Carnation bases. Dodecyl acetate is also used in flavor compositions for imitation Butter, Lemon, Orange, Peach, Pineapple, etc. and in various meat flavor bases. The concentration in the finished product will normally be about 1 to 6 ppm.
Preparation
By acetylation of lauryl alcohol.

Toxicity evaluation
Both the acute oral LD
50 value in rats and the acute dermal LD
50 value in rabbits exceeded 5 g/kg (Moreno, 1974). In a study of toxicity to fish, the toxic concentration of lauryl acetate to Carassius auratus and Salmo gairdnerii during a 6-hr observation period at 15°C was found to be 5.20 mg/litre.The surface tension (50.1) was not related directly to the toxicity
(Marchetti, 1964).
