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.

Personal care1 use researched4 sourced claims

Where it turns up: spicy, clove-like scent, fragrance allergen. Detox My Life researched eugenol 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)

ConsensusSuspected carcinogenconfidence 90%

Methyl eugenol, a related compound naturally occurring in some eugenol-rich essential oils, is a suspected carcinogen in animal studies and is tightly restricted in leave-on cosmetic products.

Why here: Methyl eugenol can be present as a contaminant or natural component in eugenol-containing ingredients used in leave-on cosmetics.
What would have to be true: Dermal exposure to leave-on products containing methyl eugenol above 0.0002% (EU/UK limit).

ConsensusRestrictedconfidence 90%

Eugenol is a restricted ingredient in cosmetics, with EU regulation mandating its listing on ingredient labels if it exceeds 0.001% in leave-on products.

Why here: Regulatory bodies impose restrictions on eugenol in leave-on cosmetics due to its potential for skin sensitization.
What would have to be true: When eugenol concentration in a leave-on cosmetic product exceeds 0.001%.

Sources the engine cites:

EUGENOL – Ingredient - COSMILE Europe — cosmileeurope.eu (2026) · regulator or public body

ConsensusIrritant · allergenconfidence 90%

Eugenol is a well-documented skin sensitizer that can cause allergic contact dermatitis.

Why here: Repeated low-level exposure from leave-on products is a classic route to sensitization.
What would have to be true: When present in leave-on products above 0.001% (EU labeling threshold) or at concentrations exceeding IFRA limits.

EmergingOxidation by-productsconfidence 80%

Eugenol can oxidize into reactive species like ortho-quinone upon contact with air or skin enzymes, which can bind to skin proteins and potentially trigger an immune response leading to skin sensitization.

Why here: Leave-on products provide continuous exposure to air and skin enzymes, facilitating oxidation.
What would have to be true: Dermal contact with eugenol in leave-on products.

Not researched here

The engine has no dossier for eugenol 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.
