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 Delta-3-Carene safe when breathed in?

Q: Is delta-3-carene safe when breathed in?

Under the app's default Cautious lens, delta-3-carene when breathed in rates Watch: worth watching; the app would list a cleaner alternative type. 2 sourced concerns count (irritant · allergen, consensus tier; oxidation by-products, emerging tier). This is research with sources, not medical advice.

Where it turns up: pine scent, reacts with ozone. Detox My Life researched delta-3-carene 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.

Mainstream shows consensus claims only; Cautious adds emerging research; Based adds fringe claims, labelled as such. The last column counts, under Cautious, the sourced concerns, the findings in its favour and the fringe claims Based would add.

Breathed in Watch

Under the default Cautious lens delta-3-carene when breathed in rates Watch: worth watching; the app would list a cleaner alternative type. Mainstream (consensus only) rates it Watch; Based (adds the fringe) rates it Watch. Researched 2026-09-03.

Sourced concerns (2)

ConsensusIrritant · allergenconfidence 90%

Inhalation of delta-3-carene can cause irritation to the respiratory tract and mucous membranes.

Why here: When delta-3-carene is inhaled, it directly contacts the tissues of the respiratory system, leading to irritation.
What would have to be true: Exposure to higher concentrations (e.g., above 225 mg/m3) or prolonged inhalation.
The other side: N/A.

Sources the engine cites:

EmergingOxidation by-productsconfidence 80%

Delta-3-carene can undergo oxidation to form highly oxidized organic molecules (HOMs) and secondary organic aerosols (SOA), which are considered detrimental to human health.

Why here: When delta-3-carene is released into the air (e.g., from an essential oil diffuser), it can react with atmospheric oxidants to form these byproducts, which can then be inhaled.
What would have to be true: Inhalation of air containing oxidized delta-3-carene, particularly in environments where oxidation can occur (e.g., presence of ozone, UV light).
The other side: N/A.

Not researched here

The engine has no dossier for delta-3-carene 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.
