Ingredients higher up in an ingredient list are typically present in a larger amount. Disodium EDTA is a chelating agent. It grabs onto and deactivates metal ions that sneak into your products from water, packaging, or air. This ingredient mainly works behind the scenes and helps with: On top of that, this ingredient can counteract the effects of hard water by binding to the minerals in it. One thing worth knowing is that Disodium EDTA has been shown to be a mild penetration enhancer. It can help other ingredients absorb into skin more effectively which can be a double-edged sword (great for actives, but can also make the active too strong if you have sensitive skin). Clinical patch testing showed no significant skin irritation at typical use concentrations and minimal dermal absorption. You'll most likely see this ingredient near the end of an ingredient list. It's typically found in concentrations less than 1%. Pentylene Glycol (1,2-pentanediol) is a multitasking little diol with three main roles in a formula: Research on alkanediols (the family pentylene glycol belongs to) show they work by disrupting microbial cell membranes. This disruption helps the primary preservative system in a product work more effectively at lower doses. On the safety side, the Cosmetic Ingredient Review Expert Panel has concluded this ingredient to be safe as used in current cosmetic practices + concentrations. Typical use levels in a formula run about 1-5%. Sodium Hyaluronate is the salt form of hyaluronic acid. It is a long sugar chain that is naturally found in your skin, joints, and connective tissue that maintains hydration and elasticity. In skincare, it works as a humectant. It pulls water from the environment and deeper layers of skin and binds it to the surface. Interestingly, the size of the molecule affects its behavior: Some clinical evidence links low molecular weight versions to improved wrinkle depth, elasticity, anti-inflammatory effects, and barrier repair. Many serums use a blend of both weights so you can get surface hydration plus longer-lasting and deeper effects. You'll typically see concentrations between 0.1-2% for this ingredient. Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product. 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!
