Ingredients higher up in an ingredient list are typically present in a larger amount. Cetyl Alcohol is a fatty alcohol. Fatty Alcohols are most often used as an emollient or to thicken a product. Its main roles are: Though it has "alcohol" in the name, it is not related to denatured alcohol or ethyl alcohol. The FDA allows products labeled "alcohol-free" to have fatty alcohols. This ingredient may not be fungal acne safe. It is a primary fatty alcohol with a chain length above 12 carbons. A study from 2019 show Malassezia can feed on fatty alcohols in this range, so it may trigger fungal acne in those prone to it. Cetyl Palmitate is a wax-ester that pulls triple duty as an emollient, thickener, and emulsion enhancer. It helps enhance the texture of products by giving a smooth, silky feel while helping to stabilize the formula. The emollient action softens skin and reduces moisture loss. This ingredient is considered safe and human testing of concentrations between 2.5-2.7% were found minimal irritation. Just know, there have been very rare cases of the palmitate family causing contact dermatitis. This ingredient may not be fungal acne safe because it contains a C16 ester (palmitic acid) that falls into the C11-24 range that Malassezia can feed on. 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. Jojoba Esters is a wax created from Jojoba oil. It is an emollient and film-forming ingredient. In bead form, it is an exfoliator. This ingredient has high oxidative stability, meaning it doesn't break down when exposed to oxygen. Its similarity to our skin's natural oils makes it a great emollient. Emollients help soften and soothe our skin by creating a barrier on top. This barrier helps trap moisture in, keeping skin hydrated. It is created using either the hydrogenation or transesterification processes on jojoba oil. 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 da
