Steareth-2
Explained
Steareth-2 is a waxy compound used to emulsify ingredients. It is created from polyethylene glycol and stearyl alcohol. The 2 stands for the number of ethylene oxide units used to create this ingredient.
Due to the low degree of ethoxylation, the molecule stays mostly oil-loving. That's why you'll often see it paired with water-loving steareth-20 or steareth-21 to create elegant emulsions.
In testing, this ingredient was nontoxic in acute oral studies and not a skin irritant or sensitizer.
You might hear concerns about 1,4-dioxane as a byproduct of ethoxylation; this is well-known in the industry and is controlled through purification steps before the ingredient is blended into finished products.
