Carnauba wax

Japanese: カルナウバ蠟 - カルナウバろう(英語表記)carnauba wax
Carnauba wax
It is made by scraping off the wax exuded from fresh leaves or petioles of the wax palm, melting it in hot water, and pouring it into a mold to solidify. The main components are esters of higher fatty acids (carbon numbers C = 22, 24, 26, 28) and higher alcohols (C = 24, 26, 28, 30, 32, 34), with 75% being cerotic acid melissyl C 25 H 51 COOC 30 H 61 , which is derived from cerotic acid (C = 26) and melissyl alcohol (C = 30). In addition to the esters (80-81%), it also contains 1-1.5% free fatty acids such as carnaubic acid (lignoceric acid, C = 24) and 9-10% free alcohols such as ceryl alcohol (C = 26).
