Versatile
The nice thing about SLSa is that it is very versatile, it can be used on basically all skin and hair types. Another benefit is that it is free of sulfates.
Let’s talk about the bubbles
SLSa is made of very small particles that dissolve quickly. (This is why it is commonly used in bath bombs). The bubbles that this surfactant creates are long lasting and the lather is thicker.
Caution
You always want to use cation when working with SLSa, as the particles are so fine. Be sure to always wear a face mask. I swear, the little particles are lighter than air. Any movement and they are floating up in the air.
Surfactant Use Calculator
When working with any surfactant, you are going to want to run your formula through a surfactant calculator. I use the one from Making Skincare that can be found here.
