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. 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. This ingredient is a silicone elastomer that works as a texture enhancer, adds a silky slip, and also helps absorb excess oil. Because it's a large macromolecule that's insoluble in water and chemically inert, it's not expected to penetrate or be absorbed into skin. Human patch tests with a facial lotion containing 1% of this ingredient found no sensitization. This ingredient is also known as Octinoxate and is one of the oldest and most widely used chemical UV filters in skincare. It has a simple job: soap up UVB radiation (290-320 nm), the wavelengths responsible for sunburn and a big chunk of long-term sun damage. In formulas, it's always paired with a separate UVA filter because octinoxate solely protects skin from UVB. Because it's an oil-soluble liquid, it's easy to blend into the oil phase of lotions/creams and gives a cosmetically elegant feel. The one quirk about formulating this
