Palmityl acetate Usage And Synthesis

Description

Palmityl acetate is an ester compound with a waxy odour. Palmityl acetate, an acetate ester derived from hexadecan-1-ol (palmityl alcohol), is used as an emollient, masking agent and skin conditioner. It can also be used as a plasticizer or stabilizer in producing plastics and resins. It is a pheromone constituent present in various species of mouse, arachnid and insect. It has a cosmetic role, as well as a pheromone and an epitope.

Uses

Hexadecyl Acetate is a plant sex pheromone.

Definition

ChEBI: Palmityl acetate is an acetate ester derived from hexadecan-1-ol (palmityl alcohol); used as an emollient, masking agent and skin conditioner; pheromone constituent present in various species of mouse, arachnid and insect. It has a role as a cosmetic, a pheromone and an epitope. It is functionally related to a hexadecan-1-ol.
