Hexadecyl hexadecanoate, also known as cetyl palmitate, is the ester derived from hexadecanoic acid and 1-hexadecanol. This white waxy solid is the primary constituent of spermaceti, the once highly prized wax found in the skull of sperm whales. [2] Cetyl palmitate is a component of some solid lipid nanoparticles.
Cetyl alcohol / ˈ s iː t əl /, also known as hexadecan-1-ol and palmityl alcohol, is a C-16 fatty alcohol with the formula CH 3 (CH 2) 15 OH. At room temperature, cetyl alcohol takes the form of a waxy white solid or flakes. The name cetyl refers to whale oil (cetacea oil, from Latin: cetus, lit. 'whale', from Ancient Greek: κῆτος ...
Ethylhexyl palmitate, also known as octyl palmitate, is the fatty acid ester derived from 2-ethylhexanol and palmitic acid. It is frequently utilized in cosmetic formulations. [ 1 ]
A new report from the Environmental Working Group (EWG) finds that only 1 in 4 sunscreens out of the 1,700 SPF products the organization reviewed is effective without the use of “worrisome ...
It is composed mostly of wax esters (chiefly cetyl palmitate) and a smaller proportion of triglycerides. [9] Unlike other toothed whales, most of the carbon chains in the wax esters are relatively long (C 10 −C 22). [4] The blubber oil of the whale is about 66% wax. [4] When it cools to 30 °C or below, the waxes begin to solidify. [10]
A major component of beeswax is myricyl palmitate which is an ester of triacontanol and palmitic acid. Its melting point is 62–65 °C (144–149 °F). Spermaceti occurs in large amounts in the head oil of the sperm whale. One of its main constituents is cetyl palmitate, another ester of a fatty acid and a fatty alcohol.
