Are Sunscreens Tested for Pesticides?
No. There are no FDA requirements for pesticide testing on sunscreen. No action limits. No required disclosure. A brand can formulate a sunscreen, bring it to market, and sell it without ever testing what pesticide residues its ingredients carry.
That applies to the inactive ingredients specifically. The actives get scrutinized. Everything else does not.
How the Regulatory Gap Works
Sunscreen is regulated as an over-the-counter drug by the FDA. That means the active ingredient, the thing doing the UV filtering, goes through a defined review process. The inactive ingredients sit outside that process. Pesticide residue tolerances are set separately by the EPA, under a framework built for food and animal feed. Sunscreen isn't food. The tolerance framework doesn't apply.
The result is a product category where the active gets tested and the rest of the formula is effectively unexamined for pesticide contamination.
Where the Risk Actually Lives
Most sunscreens, especially those marketed as natural or mineral, are built around botanically-derived inactive ingredients. Plant-based emulsifiers, botanical waxes, seed oils, fruit extracts. These ingredients come from crops. Crops get sprayed.
The brand sourcing those ingredients typically has no visibility into how the source crop was treated. The ingredient supplier may not know either. Nothing requires them to find out.
A pesticide screen on a cosmetic-grade orange peel wax, the kind of ingredient that shows up across sunscreens and personal care products broadly, found 8 detected pesticides. Several came back at concentrations 10x or more above what federal law permits on food crops. One of them, Teflubenzuron, has no active EPA registration in the United States at all. Not approved for use on any US crop, detected anyway.
The same problem runs across cosmetics generally. Any product relying on botanically-derived ingredients carries the same exposure. The ingredient list tells you what was intentionally added. It doesn't tell you what the source crop was treated with.
What a Short Formula Actually Means
Swellies has five ingredients. Zinc Oxide, Coco Caprylate/Caprate, Dextrin Palmitate, Polyhydroxystearic Acid, Iron Oxides.
Zinc Oxide is the active. It's a mineral. Coco Caprylate/Caprate is a synthetic ester, not a raw plant extract. Iron Oxides are mineral pigments. None of these ingredients come out of conventional agriculture. None of them carry an agricultural supply chain we can't account for.
There are no botanical waxes. No seed oils. No fruit extracts. Not because those ingredients are inherently wrong, but because every ingredient in this formula has a specific job, and none of them needed to be botanical to do it.
The five-ingredient list isn't a marketing position. It's the formula. And part of what that means in practice is a short list of supply chain questions, all of them answerable.
