My job is varied and interesting but it also does my head in.  Why?  Because everything is interesting, everything is an opportunity to learn more, be better, run faster, jump higher and solve world hunger (well, no it isn’t really but anyway) and that can become totally overwhelming.  Anyway……….

It just so happens that I’ve found myself in a surfactant bubble for the last four months  after having been invited to formulate quite a few products for quite a few different companies (8 in fact which is a nice neat number).  Anyway, not one to churn out the same old-same old day after day I’ve been playing and found a few rather fabulous combinations to tickle the taste buds and lick the dirt off even the most crusty of customers (and before you get excited that’s salt on the scales there. Table salt).

But I can’t tell you about all of that here because it’s top secret so instead I thought I’d share some basic overview notes with you about how surfactants work as believe it or not, there’s some science involved. No, really I’m serious about this science stuff………….

My notes on surfactant chemistry. 

Too hard to read?  Try this:

Anionic Surfactants form charged micelles that act like little magnets picking up dirt. They pull the dirt from a surface and it is emulsified away from the surface. This is more of a physical reaction in-situ than a chemical one as the dirt isn’t changing form on the skin as such – it is emulsified in the rinse.

They can form sphere, rod or disk-shaped micelles and it is the spheres that form the thickest mixtures. 

They work best just above their CMC (Critical micelle concentration) as this is when […]
