Ingredients higher up in an ingredient list are typically present in a larger amount. Benzyl Alcohol is an aromatic alcohol with several roles: it's a preservative, solvent, and mild fragrance component with a floral scent. This ingredient has been deemed safe for use in cosmetic formulations at concentrations up to 5%, and up to 10% in hair dyes. You'll typically see 0.5-2% in most rinse-off or leave-on products. As a preservative, it works by disrupting the membrane of microbial proteins. This helps keep bacteria and fungi from growing in your products. The sensitization picture is actually quite assuring as well:of nearly 71,000 patients patch tested with benzyl alcohol, only 0.21% showed a positive reaction with most of them being weakly positive. This led researchers to conclude that benzyl alcohol cannot be regarded as a significant contact allergen. It is worth noting this ingredient is classified as one of the EU's regulated fragrance allergens and restricted to 1% in finished products. Labels must also declare it in concentrations above 0.001% in leave-on products and 0.01% in rinse-off products. At concentrations around 5%, localized redness and itching can appear as a direct irritant response and not as a true allergic reaction. 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
