Ingredients higher up in an ingredient list are typically present in a larger amount. Arachidyl Alcohol is a fatty alcohol made from the the arachidic acid found in peanut oil. Despite having "alcohol" in the name, it is not related to denatured alcohol or ethanol. This ingredient is a multitasker: Just be sure to patch this ingredient if you have a peanut allergy (though this ingredient is highly processed and the allergenic proteins are typically removed). This ingredient is a plant-based surfactant and emulsifier. It helps oil and water based ingredients mix evenly to improve formula stability without adding a "greasy" feel. Behenyl Alcohol is a type of fatty alcohol (these are different from the drying, solvent alcohols). Fatty Alcohols have hydrating properties and are most often used as an emollient or to thicken a product. They are usually derived from natural fats and oils; behenyl alcohol is derived from the fats of vegetable oils. Emollients help keep your skin soft and hydrated by creating a film that traps moisture in. In 2000, Behenyl Alcohol was approved by the US as medicine to reduce the duration of cold sores. Dimethicone is a type of synthetic silicone created from natural materials such as quartz. It is also known as polydimethylsiloxane. What it does: Dimethicone comes in different viscosities: Depending on the viscosity, dimethicone has different properties. Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions about the viscosity. This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient. Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur when layered with products. When mixed with heavy oils in a formula, the outcome is also quite greasy. 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
