DODECYL ACETATE

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.

The Uses of DODECYL ACETATE

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.

What are the applications of Application

Dodecyl acetate is a dodecyl ester of acetic acid

Preparation

By acetylation of lauryl alcohol.

Definition

ChEBI: Dodecyl acetate is a carboxylic ester.

What are the applications of 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.

Toxicity evaluation

Both the acute oral LD₅₀ value in rats and the acute dermal LD₅₀ 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).
