Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Propanediol is an all-star ingredient. It softens, hydrates, and smooths the skin.
It’s often used to:
Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.
Learn more about PropanediolSodium Phytate is the sodium salt of Phytic acid, a compound that plants store phosphorus in. It's the plant-derived alternative to ingredients like Disodium EDTA.
In skincare, this ingredient is a chelator that grabs onto trace metal ions like iron and copper that sneak into formulas through water/raw materials.
Those metals speed up oxidation so binding them keeps oils, fragrance, and actives from going off, stops color changes, and helps the preservative system work harder.
Survey data shows usage levels range from 0.0099%-0.5% in leave-on products, 0.025%-0.3% in rinse-off, and up to 0.05% in eye-area products. Suppliers typically recommend a range between 0.05-0.5%.

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!
