Ingredients higher up in an ingredient list are typically present in a larger amount. Caprylhydroxamic Acid is a chelating agent that helps cosmetics stay fresh, stable, and consistent over time. Chelating agents help prevent metal ions from binding to other ingredients. This helps prevent unwanted reactions and effects from using the product. It also helps prevent the growth of unwanted microbes in products that contain water. Caprylhydroxamic Acid is often used with natural antimicrobial products as an alternative to preservatives. 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. Methylparaben is a synthetic preservative and one of the most widely used in the world. It has a simple, but important job: prevent your products from going bad by stopping bacteria, yeast, and mold from growing. Typical use levels are low, often 0.1-0.3%. This is also one of the most heavily studied preservatives out there and major regulatory bodies have repeatedly given it the green light. In 2023, the EU's Scientific Committee on Consumer Safety (SCCS) confirmed that this ingredient is safe up to 0.4% on its own, of up to 0.8% when mixed with other paraben esters. Here's the science behind the noise behind parabens/hormones as well: Methylparaben shows very weak estrogen-like activity in vitro tests (more than 1,000x weaker than your body's own estradiol). In vivo (live-organism) studies don't support a meaningful endocrine-disrupting effect either. You get a stronger estrogenic effect from eating tofu, actually. It's also a low sensitizer and allergic reactions are uncommon; they usually happen on damage or brok
