Ingredients higher up in an ingredient list are typically present in a larger amount. Butylene Glycol (or BG) is used within cosmetic products for a few different reasons: Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients. Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness. 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. Here's the important part: these tiny levels are just a cutoff the FDA uses to decide which ingredients need more testing and doesn't mean anything harmful was found. The researchers were clear that the results are no reason to stop wearing sunscreen. Homosalate is an oil-soluble organic UVB filter that has been a sunscreen staple for decades. Its job is to absorb UVB rays (~295-315 nm) and protect your skin against sunburn, This is one of the more photostable organic UV filters; it holds up pretty well under UV and a 2022 quantum-chemistry study found it stays stable in sunlight. It's actually so reliable that formulators often pair it with shakier ingredients like oxybenzone and avobenzone. Formulators also use it to help dissolve the other UV filters into the oil phase. One thing to keep in mind: "stable" isn't the same as "strong". On its own, homosalate is actually a pretty weak UV filter so it's better off as a helpful team player that helps boost overall SPF protection. The safety picture is a bit nuanced but not scary. This ingredient has a long track record of being gentle and regulators agre
