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. 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. This ingredient is a synthetic, salt form polymer built from acrylic acid, ethacrylic acid, or their simple esters. It works as a binder, film former, and viscosity increasing agent. Typical concentrations start at around 0.5% but can go up to 25% for film-forming or binding.
