Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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.
Learn more about Steareth-2Steareth-20 is an emulsifier and solubilizer. It is created from stearyl alcohol with ~20 units of ethylene oxide to give it a strong preference for water.
As an emulsifier, it helps oil-in-water emulsions like lotions, creams, and cleansers stay stable. It also solubilizes small amounts of oil-loving ingredients (like fragrance) into water-based formulas.
You'll likely find this ingredient with steareth-2 (it's oil-loving sister) where the two work together to give products a cushiony feel.
Typical use levels sit at around 1-5% and this ingredient has been found to be non-irritating by the CIR Expert Panel.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
