Chemistry Thursday: Fragrance & essential oils – Let’s review the masculine scents we met last week, and we’ll update our charts for the series (part 65)

by

Join me for this awesome Chemistry Thursday post in which we’re looking at how masculine scents differ from those we’ve met in the series so far. We’ll also look at hexyl cinnamyl (aka hexyl cinnamate or ⍺-hexylcinnamaldehyde), hexamethylindanopyran (Galaxolide), tetramethylacetyloctahydronaphthalenes (Iso E Super, synthetic), and phenethyl alcohol, molecules found in more “masculine” fragrance oils than...

Welcome back to our introduction to cosmetic chemistry series. We’ve been taking a look at foamy, bubbly, lathery™ surfactants in this part of the series, focusing on the sulphur based surfactants like sulfates, sulfonates, isethionates, and sulfate esters, and today we’re looking at the last surfactants in this category – sulfosuccinates, specifically disodium laureth sulfosuccinate...

Chemistry Thursday: Foamy, bubbly, lathery™ surfactants – isethionates – SCI, SCMI, and SLMI (part 56)

by

Let’s take a closer look at sodium cocoyl isethionate (SCI), sodium lauroyl methyl isethionate (SLMI), and sodium cocoyl methyl isethionate (SCMI). These are called ester-based surfactants, and they’re related to the sulfates, sulfoacetates, and sulfonates – all called sulphur (sulfur) based surfactants – which you’ll see in a minute. These are some of my favourite...

Chemistry Thursday: Foamy, bubbly, lathery™ surfactants – increasing viscosity, the salt curve, and more (part 54)

by

Let’s recap what we’ve learned so far, look at last week’s assignment, then take a look at how to increase viscosity in surfactant-based products, something we have to master to make awesome products! An important note about this series – it’s here for life. It isn’t going anywhere. If you want to take a break...
