Catch up on this series: Part one, the chemistry and nomenclature of esters; part two, types of esters and their sensory characteristics; and part three, chemistry of the sensory characteristics. We also took a look at the hydrolysis of esters, and simple esters! Yesterday, we met cetyl palmitate, a simple waxy, flaky, oil soluble ester that...
Catch up on this series: Part one, the chemistry and nomenclature of esters; part two, types of esters and their sensory characteristics; and part three, chemistry of the sensory characteristics. We also took a look at the hydrolysis of esters, and simple esters! Cetyl Palmitate is a simple ester, a white, waxy flake used as a...
In the post on simple esters, I noted that we don’t want to use these in products that have acidic or alkaline pH ranges lower than 5 and more than 10 because they’re unstable and can hydrolyze. What exactly does this mean? Hydrolysis is “any chemical reaction in which a molecule of water ruptures one...
Catch up on this series: Part one, the chemistry and nomenclature of esters; part two, types of esters and their sensory characteristics; and part three, chemistry of the sensory characteristics. Esters are created when an alcohol and an acid react. In the case of simple esters, this is when a fatty alcohol and a fatty...
Catch up on this series: Part one, the chemistry and nomenclature of esters, and part two, types of esters and their sensory characteristics. There are quite a few factors that contribute to the functionality of the ester, that is to say these factors contribute to the viscosity, skin feel, melting point, liquidity, surface tension, and...
