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...

Chemistry Thursday: Introduction to fragrance and essential oils – meeting a few more fragrance compounds, and learning about the top, middle & base notes (part 59)

by

Welcome back to a bit of a tangent for the next few weeks as we’re looking at the chemistry of fragrance and essential oils as they have such a huge impact on our products, especially surfactant-based ones. This week, we’re looking at some more fragrance compounds, like pinene, camphor, vanillin, benzyl alcohol, and benzyl benzoate!...

Chemistry Thursday: Introduction to fragrance and essential oils – how they affect surfactants, along with benzene and limonene (part 58)

by

Welcome to Chemistry Thursday! I’m on a bit of a tangent for the next few weeks as we’re looking at the chemistry of fragrance and essential oils as they have such a huge impact on our products, especially surfactant-based ones. In this week’s post, we’re defining the differences, looking at benzene, learning about the structure...

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...
