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. This ingredient is also known as African Palm Oil. It is a plant-based emollient that is slightly occlusive leaning. As an emollient, it helps moisturize the skin and supports the lipid barrier. Clinical testing found it improved skin hydration, reduced transepidermal water loss (TEWL), and increased skin elasticity. The Cosmetic Ingredient Review Panel has assessed the available safety data and found it to safe in cosmetics. The comedogenic rating of 2/5 means it is low-to-moderate risk of pore clogging; please remember comedogenic ratings cannot predict how the overall formula will behave on skin. Because its dominant fatty acids (palmitic and oleic acid) fall within the C11-24 range that Malassezia can use as a growth substrate, this ingredient may not be fungal acne safe. Phenoxyethanol is one of the most widely used preservatives in skincare (and for good reason!). It has a large spectrum of antimicrobial activity and especially effective bacteria, yeast, and mold while only having a weak effect on your skin's natural microbiome. On a cellular level, it disrupts the cell membranes of microbes by poking holes that make the cell leak. This shuts down the chemical reactions the microbe needs to make energy so it can no longer survive. Another perk of this ingredient is that it stays functional across a wide pH range (3-10). You'll often see it paired with boosters like Ethylhexylglycerin; one study showed that a 1:9 ratio of Ethylhexylglycerin to Phenoxyethanol damages bacterial membranes as effectively as doubling the Phenoxyethanol concentration on its own. Typical use concentrations range from 0.3-1% depending on the formula, and this ingredient is capped at 1% int the EU. Safety-wise, the fear mongering does not hold up to the evidence. The EU's Scientific Committee on Consumer Safety and FDA consider it safe as a preservative at up
