Ingredients higher up in an ingredient list are typically present in a larger amount. Aminomethyl Propanol is used to adjust the pH of products. It is also used as a base to create other organic compounds. Having a balanced pH is important for protecting your skin. Aminomethyl propanol is safe to use in cosmetics up to 1%. It is soluble in water. 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%. Ethylhexylglycerin is created from glycerin. It is a multitasker ingredient that: The CIR Expert Panel found minimal skin absorption or sensitization of any kind in a safety assessment. Though this ingredient is considered well-tolerated, a small number of cases of allergic dermatitis have been published since 2002. Just be sure to patch test if you are unsure. Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations. Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum. Topically, glycerin does several things at once: Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3. Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin. This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products. Just know very high concentrations (>40%) can feel tacky in low humidity. Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine. Lecithin is a term for a group of substances found in the cell membranes of plants, animals, and humans. They are made up of phospholipids. Thanks to its amphiphilic structure (water-loving head and oil-loving tail), it is a true multitasker: It plays well with most ingredients and is typically used at 0.1-1%. However, concentrations up to 50% have been reported in moisturizers.
