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...

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...

Chemistry Thursday: More on polyatomic ions, short introduction to solubility, and why we don’t use spring, mineral, or tap water in our formulas (part 50) Welcome back! Let’s take a closer look at polyatomic ions, some examples of compounds, and why we don’t use mineral, spring, or tap water in our products, as we work...
