Chemistry Thursday: Esters we use as emulsifiers (overview), some emulsion chemistry, the HLB system, and PEG-esters (part 32)

by

Welcome back to this introduction to cosmetic chemistry course! Let’s continue our look at esters by investigating those that work as emulsifiers. We’ll get into some emulsion theory, information on the HLB system, then get into those esters! An important note about this series – it’s here for life. It isn’t going anywhere. If you...

Chemistry Thursday: Esters we use as emollients (overview), part 31

by

Welcome back to this introduction to cosmetic chemistry course! We’ve had great fun for the last few months looking at carboxylic acids as fatty acids, but it’s time to meet some esters! Woo hoo! I’m trying to make this post shorter than the previous ones as I know it can be a lot. An important...

Chemistry Thursday: Carboxylic acids – very long chain fatty acids, behenic acid (C22:0) and higher, and how behentrimonium methosulfate (BTMS) or behentrimonium chloride (BTMC) works, part 29

by

Welcome back to our introduction to cosmetic 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 find in our ingredients and oils. This week, it’s all about behenic acid (C22:0) – the fatty acids, but more importantly, the ingredients derived...
