Chemistry Thursday: Carboxylic acids – monounsaturated long chain fatty acids, oleic acid (C18:1), and saponification, part 25

by

Welcome back to this introduction to chemistry series! I hope you’re enjoying it so far. I know I am! Let’s talk more about carboxylic acids, specifically the fatty acids we encounter over and over again in our liquid oils, solid oils, butters, and waxes. This week, we’re getting into unsaturated C18:1 fatty acids, like oleic,...

Chemistry Thursday: Carboxylic acids – medium chain fatty acids (part 22) 

by
A jar of coconut oil sits on a table with a green leaf tablecloth. A dollop of white creamy coconut oil sits on a spoon atop the jar.

In today’s post, part 22, we’re meeting medium chain fatty acids – caproic acid, caprylic acid, capric acid, and lauric acid – all of which we encounter regularly in cosmetic chemistry. An important note about this series – it’s here for life. It isn’t going anywhere. If you want to take a break or take...
