What do the Clean, Low, Watch and Swap levels mean?

They are cut from a continuous concern level the app computes from the sourced claims that the chosen evidence lens shows: each claim counts its concern class, tier weight, confidence and dose relevance, combined worst-first with a decay so one serious finding outweighs many small ones, then scaled by how much of the substance reaches you in this use. Clean is below 0.35, Low below 1.1, Watch below 2.0 and Swap above that, on a 0 to 3 scale.

Is Benzyl Salicylate safe on skin (left on)?

Q: Is benzyl salicylate safe on skin (left on)?

Under the app's default Cautious lens, benzyl salicylate on skin (left on) rates Watch: worth watching; the app would list a cleaner alternative type. 4 sourced concerns count (irritant · allergen, consensus tier; endocrine, emerging tier; environmental, emerging tier). This is research with sources, not medical advice.

Personal care1 use researched4 sourced claims

Where it turns up: floral scent, uv absorber. Detox My Life researched benzyl salicylate under one use, because the same substance means something different in each use. Every claim below carries its evidence tier, how sure the research is that it applies here, and the sources it cites. The level is computed by the app's own deterministic engine, so the page says exactly what the app would.

Sourced concerns (4)

ConsensusIrritant · allergenconfidence 90%

Benzyl salicylate is a recognized fragrance allergen and skin sensitizer in humans, requiring mandatory labeling in leave-on cosmetic products when its concentration exceeds 0.001%.

Why here: Direct and prolonged contact with the skin in leave-on products can trigger allergic reactions in sensitized individuals.
What would have to be true: Dermal exposure in leave-on products at concentrations above 0.001%.
The other side: Benzyl salicylate is classified as a weak sensitizer, and some studies indicate a very low potential to induce or elicit hypersensitivity. The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Benzyl Salicylate is safe in cosmetics when formulated to be non-irritating and non-sensitizing.

EmergingEndocrineconfidence 90%

Benzyl salicylate is linked in studies to indications of an endocrine mode of action, leading to its re-evaluation and the establishment of strict concentration limits in cosmetic products by EU regulations.

Why here: Dermal leave-on products allow for continuous skin exposure to the ingredient, which is the route of exposure relevant to endocrine disruption concerns.
What would have to be true: Dermal exposure in leave-on cosmetic products, with EU regulatory limits set for various product categories, such as a maximum of 0.7% for leave-on body products (non-spray/spray/aerosol) and 0.5% for leave-on skin and hair products (non-spray/non-aerosol, except body lotion).
The other side: The Scientific Committee on Consumer Safety (SCCS) concluded in November 2023 that despite indications of an endocrine mode of action, there is no evidence to suggest this results in adverse endocrine effects, and benzyl salicylate is considered safe for use in cosmetics at specified maximum concentrations. In vivo data often contradict in vitro findings, and relevant studies have not confirmed an endocrine disrupting potential in humans.

EmergingEnvironmentalconfidence 80%

Benzyl salicylate is suspected to be an environmental toxin, and its synthetic production can contribute to greenhouse gas emissions.

Why here: The ingredient's presence in cosmetic products that are eventually washed off or enter the environment through other means contributes to its environmental impact.
What would have to be true: Environmental release from the use and disposal of cosmetic products containing benzyl salicylate.
The other side: The Scientific Committee on Consumer Safety (SCCS) mandates do not address environmental aspects, and environmental concerns are considered under the REACH Regulation. Some synthetic versions of benzyl salicylate are compatible with COSMOS and other organic certification schemes, indicating that they meet certain sustainability standards.

EmergingTheoryconfidence 70%

Animal studies have shown that benzyl salicylate is associated with developmental and reproductive effects at moderate doses, including embryonic resorption, offspring mortality, and neural tube defects in rats.

Why here: Dermal absorption from leave-on products could lead to systemic exposure, potentially impacting reproductive and developmental health.
What would have to be true: Systemic exposure, as observed in animal studies at doses such as 30 mg/kg/day, 100 mg/kg/day, and 300 mg/kg/day in rats.
The other side: The Scientific Committee on Consumer Safety (SCCS) evaluated various human and animal tests, including toxicokinetics, cytotoxicity, and carcinogenicity, and concluded that benzyl salicylate is safe for use in cosmetic products at specified maximum concentrations, implying that developmental or reproductive effects are not considered a concern at relevant human exposure levels. The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Benzyl Salicylate is safe in cosmetics in the present practices of use and concentration.

Not researched here

The engine has no dossier for benzyl salicylate when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.

This is research, not medical advice. Detox My Life shows sourced claims sorted by evidence tier. It does not diagnose, treat, or tell you to start or stop anything. Talk to a qualified professional about your health.

Scan your own. The app reads any product label with your camera, works out how you are about to use it, and researches every ingredient for that use with live sources. Every scan adds to a Detox Score for your home, where 50 is a typical home in your region, and a plan of next swaps.
