Chemistry: Atoms! Protons, neutrons, and electrons – oh my! (Part 2) 

by

Welcome to part two of this series on learning chemistry! In part one, we looked at the resources and materials we need to study chemistry. Today, in part two, we’ll look at the parts of an atom – protons, neutrons, and electrons! The periodic table! The periodic table! You see it everywhere, but what the heck...

Basic chemistry: Introduction to the course and suggested supplies & resources (part one)

by
Three Ehrlenmeyer flasks sit on a lab bench. The first contains light pink liquid. The second, clear liquid. The third, bright pink liquid. This was a class on titration and the colours indicate how alkaline the liquid is.

Welcome to this introductory course on chemistry that I hope will give you enough information to get to know your ingredients and how to use them! It’ll continue to be a work in progress as we cover the basics, like atoms, the periodic table, ions, and bonding. As time goes on, I’ll be adding modules...

Cosmetic chemistry: Oxidative stability index or oil stability index (OSI)

by

Let’s take a look at this concept before we meet a new emollient, jojoba esters 15! Woo hoo! What is the OSI? OSI – oxidative stability index or oil stability index – is a measurement in hours of the “relative resistance of fat and oil samples to oxidation”, an approved method by the American Oil...

Let’s analyze an absolutely atrocious article on glycerin to learn more awesome chemistry, then talk a little about reputable sources and formulating faves! 

by

This article has been making the rounds recently and I wanted to analyze it because it is so absolutely magnificently wrong in so many ways, I thought it could be an interesting exercise in analyzing an article and having loads of chemistry fun while doing it! Article: HOW DOES GLYCERINE REACT WITH WATER? Related posts...

Chemistry: The chemistry of humectants – water binding, hydrogen bonding, polarity, osmosis, and so much more!

by

Before we meet a new humectant, AQUAXYL™, let’s take a look at how humectants work! Before we start… Take a look at my humungous humectants section of this site, found under the “ingredients” tab in the menu bar. What does it mean that humectants have “water binding” ability?  Humectants are hygroscopic, meaning they draw water...
