Surfactants: Building viscosity – creating gels (updated)

This is the last in the very long series of posts on surfactants before we get to some super fun formulating! We’ve covered the idea of increasing the micelle size and increasing the concentration of the surfactants, so let’s take a look at creating gels. There are a few ways to create a gel that...

Surfactants: Building viscosity – increasing micelle size

The second way to increase the viscosity of our surfactant-y creations is to increase the size of the micelles. (Please click here for a refresher on micelles!) We learned in the post about increasing mildness that increasing micelle size can reduce irritation, so you’re not only building viscosity, you’re decreasing irritation! (I love two-for-one processes!)...

Surfactants: Building viscosity – increasing surfactant concentration

We’re getting ready to do some formulating, but we need to take a few moments to look at how to thicken our surfactant based creations. There are three ways to thicken a surfactant based creation – increase the concentration of the surfactants, make the micelles larger, or create a gel. (There’s a brief summary about...

Skin tightness is associated with a marked decrease in the water content of our stratum corneum, and can be the first sign that repeated use of this product could lead to scaling, flaking, and...
