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 Flavor safe on skin (left on)?

Q: Is flavor safe on skin (left on)?

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

1 use researched4 sourced claims

Detox My Life researched flavor 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.

Level by use and lens

On skin, left on	Watch	Watch	Watch	4 · 0

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.

Safer swaps: the app's swap catalog has no entry tied to this ingredient yet. When you scan a product that contains it, the app suggests cleaner alternative types for that product; the swap categories list what the catalog covers today.

Sourced concerns (4)

ConsensusRestrictedconfidence 90%

The European Union mandates the individual labeling of 82 specific fragrance allergens if their concentration exceeds 0.001% in leave-on cosmetic products, and some fragrance ingredients are prohibited.

Why here: This regulation aims to protect consumers from allergic reactions by providing transparency on ingredients in products left on the skin, allowing sensitized individuals to avoid them.
What would have to be true: Dermal application of leave-on products containing regulated flavor/fragrance allergens above specified thresholds.
Dose: Applies past a stated amount (about 0.001 mg a day); discounted at a typical serving.

Sources the engine cites:

Fragrance allergens labelling - Internal Market, Industry, Entrepreneurship and SMEs — europa.eu (2023) · regulator or public body

ConsensusIrritant · allergenconfidence 90%

Flavor ingredients in dermal leave-on products are a common cause of allergic contact dermatitis and skin irritation in sensitive individuals.

Why here: Leave-on products result in longer skin contact, increasing the potential for skin reactions such as irritation and allergic sensitization.
What would have to be true: Dermal application of leave-on products containing flavor ingredients, especially at concentrations exceeding regulatory thresholds.
Dose: Applies past a stated amount; discounted at a typical serving.

EmergingSuspected carcinogenconfidence 70%

Some chemicals that may be present in flavor mixtures, such as styrene, benzophenone, and methyleugenol, are identified as possible or reasonably anticipated human carcinogens.

Why here: Repeated dermal exposure to leave-on products containing these substances can increase the likelihood of chronic, low-level interaction with potentially carcinogenic substances.
What would have to be true: Dermal application of fragranced leave-on products containing these specific chemicals.
The other side: The long-term risks of exposure to these chemicals at concentrations typically found in cosmetics and absorbed by the skin are not fully understood, and research often focuses on higher, occupational exposure levels.

EmergingEndocrineconfidence 80%

Synthetic flavor mixtures in dermal leave-on products can contain endocrine-disrupting chemicals (EDCs) such as phthalates, synthetic musks, and benzyl salicylate, which may interfere with hormone function.

Why here: These chemicals can be absorbed through the skin and remain in the body for extended periods after application, potentially mimicking or blocking natural hormones and disrupting the endocrine system.
What would have to be true: Dermal application of fragranced leave-on products containing these specific EDCs.
The other side: Regulatory bodies in the U.S. and Canada suggest that the levels of phthalates and parabens currently used in cosmetics pose a low risk, though some studies classify them as EDCs.

Not researched here

The engine has no dossier for flavor 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.
