Sodium laureth-2 sulfate vs Sodium laureth-3 sulfate
Hi All.
At the same % of active ingredient, is there any difference in cleansing/foaming/safety between Sodium laureth-2 sulfate and Sodium laureth-3 sulfate?
Should one make any necessary adjustments while shifting between the two?

We had a similar question asked and answered in this post https://chemistscorner.com/cosmeticsciencetalk/discussion/comment/41552#Comment_41552
“As we increase the moles of EO from one to two to three, how does it impact the performance of the product? Generally speaking here is how:
- Increases solubility
- Increases mildness
- Increases flash foam
- Decreases foam stability
- Decreases viscosity buildingThese differences are not very prominent in most cases except for viscosity building; there is a significant difference between 2 mole and three mole. Two mole gives higher viscosity. In most applications formulators tend to use the 2 mole product like our Calfoam® ES-302.”
^ that’s from a product info sheet from Calfoam in the forum
