Esters: Cetyl palmitate, simple ester

by

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...

Esters: The hydrolysis of esters

by

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...

Esters: Simple esters

by

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...

What are esters? Part three: Chemistry of the sensory characteristics or why they feel the way they do

by

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...

What are esters? Part two: Types of esters & their sensory characteristics

by

Thanks for joining me for part two of this series on esters. Yesterday, we looked at the chemistry and nomenclature of esters. Today, let’s take a look at why we might use esters in our products, and what they bring to the party. We use esters for all kinds of reasons – as emulsifiers, as...
