Ingredients higher up in an ingredient list are typically present in a larger amount. Cyclopentasiloxane (D5) is a lightweight silicone that mostly acts as an emollient and solvent in cosmetics. Its the reason your products feel silky, fast-spreading, and non-greasy. Since D5 is volatile, it does its thing and then evaporates off the skin quickly. The safety profile of this ingredient is reassuring; the US CIR Expert Panel concluded D5 is safe as used in cosmetics and Health Canada concluded that D5 is not harmful to human health or the environment as currently used in cosmetics There's a study that people mention about D5 in a rat study showing tumors. This study is related to long-term inhalation of high D5 levels. Regulatory bodies have judged this study to be not applicable in topical skincare since skin absorption of D5 is very low and we're not really inhaling huge amounts of D5. The only restriction for this ingredient is environmental. The European Chemicals Agency (ECHA) restricted D5 in wash-off cosmetics at or above 0.1% due to their persistence in water. Dimethicone Crosspolymer is a silicone created by modifying dimethicone with hydrocarbon side chains. Due to its large size, it does not penetrate skin. It is considered non-occlusive. Dimethicone Crosspolymer is used to stabilize and thicken products. It also helps give products a silky feel. This ingredient is an synthetic emollient, emulsifier, and used as a surface treatment for pigment particles (like iron oxides or titanium dioxide). The “triisostearate” part of this ingredient is an ester derived from isostearic acid, a long-chain fatty acid. It "wraps" these ingredients in a form of slippery jacket so they disperse more evenly in oils, glide better on skin, and stick longer without smudging. Human repeat insult patch tests on foundations containing this ingredient found no sensitization concerns. Since isostearic acid is a C18 fatty acid, it falls within the carbon chain length that Malassezia can potentially metabolize. This is why this ingredient may not be fungal acne safe. Zinc Oxide (ZO) is a mineral broad-spectrum UV filter and the broadest-spectrum filter recognized by the FDA. It covers everything from UVB through to long-wave UVA. On top of sun protection, it has skin protectant and skin-soothing properties too. Here's a myth worth busting: mineral filters are usually described as working by "reflecting" or "bouncing" UV off your skin. That's mostly not true: when researchers actually measured it, ZO and Titanium Dioxide reflect only about 4-5% of UV (less than SPF 2 worth of protection). The vast majority of the work (~95%) is done by absorption, similar to chemical UV filters. ZO is a semiconductor that absorbs UV photos through its energy band gap. So the old "physical blocker vs. chemical absorber" framing is really an oversimplification. Zinc Oxide is one of the most effective broad-spectrum UV filters out there. It p
