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. Ethylhexyl Salicylate (also called Octisalate or Octyl Salicylate) is an oil-soluble organic UV filter that's been used in sunscreen since the 1950's. It absorbs UVB light in the 280-320 nm range with a peak absorbance around 306 nm. You'll often see it paired with other UV filters to boost overall SPF because octisalate is a fairly week filter on its own. The reason you'll see it so often is because it can help solubilize and stabilize the trickier filters like oxybenzone and avobenzone. Unlike these filters, octisalate has pretty good photostability and doesn't create skin-damaging free radicals when exposed to sunlight. The fatty-alcohol part of the molecule also gives it a light, emollient feel so it doubles as a nice texture enhancer. Usage levels vary around the world: Safety-wise, this ingredient has a pretty reassuring track record. The EU's Scientific Committee on Consumer Products (SCCP) found very low skin penetration in human skin tests and negative results for irritation, phototoxicity, and photoallergy. The real-world allergy risk is pretty low too; a 2012 European study of 1,031 people recorded only 2 reactions to it (a rate of 0.19%). You might have seen scary headlines about sunscreen getting into your blood. In 2019, the FDA found that several chemical filters can absorb through the skin and show up in the bloodstream at small but measurable levels. Her
