Ingredients higher up in an ingredient list are typically present in a larger amount. Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a synthetic polymer. It is used to thicken, emulsify, and improve the texture of products. As an emulsifier, it helps stabilize oil-in-water emulsions to give products an elegant feel when applied. It can also form a thin protective film on skin. One study found that a formula using this polymer helped slow down how quickly other ingredients (like DEET) were absorbed through skin. A 2024 study of over 1,300 patients confirmed that sensitization to this ingredient is rare. It is also non-mutagenic and has a clean track record. Also known as Avobenzone, this ingredient is an oil-soluble used to absorb the full spectrum of UVA rays (peak 357 nm). It's one of the most effective UVA filters available but has a major caveat of photostability: avobenzone is susceptible to photodegradation. This means it can lose efficacy when exposed to sunlight without the help of a stabilizing agent. Studies show antioxidants (like vitamin E or vitamin C) and some UV filters (like octocrylene and Tinosorb S) can meaningfully improve its stability in a formulation. The maximum allowable concentration according to regulation is 3% in the US + Canada, and 5% in the EU, Australia, China, Korea, and ASEAN countries. It has a well-support safety profile: a comprehensive 2025 review found minimal toxicity with no evidence of carcinogenicity. Overall, avobenzone is a safe and regulated ingredient used in sunscreen for over 40 years. C12-15 Alkyl Benzoate is a lightweight emollient made by combinig benzoic acid with fatty alcohols that are 12-15 carbons long. In cosmetics, it plays several roles: The Cosmetic Review Expert Panel has concluded the alkyl benzoate group to be safe as used in cosmetics; it wasn't found to be a skin irritant and unlikely to be absorbed due to its low water solubility. This report recorded almost 1000 reported uses with concentrations up to 59% in leave-on products but your cosmetics will typically use 0.5-15% depending on the product. It's often called a "SPF booster": this is because it keeps UV filters properly dissolved and evenly distributed to support a sunscreen's performance. It doesn't actually raise SPF on its own. Overall, this ingredient is well tolerated. This ingredient is fungal acne safe because it is an ester of benzoic acid. Think of this ingredient as two parts stuck together: an oily part and an acid part. Malassezia only gets a meal when it can snip off a fatty acid to eat. With C12-15 Alkyl Benzoate, the acid part is benzoic acid, which isn't a fatty acid and which the yeast can't use as food. Benzoic acid is actually used as a preservative to stop yeast from growing. The oily part is a blend of C12-15 fatty alcohols but fatty alcohols in this size range can support only a little Malassezia growth (mostly for one species of Malassezia as well). In the
