Is diisodecyl phthalate safe in food and drink?

Under the app's default Cautious lens, diisodecyl phthalate in food and drink rates Swap: the app would put this near the top of your swap plan. 3 sourced concerns count (endocrine, consensus tier; metabolic, consensus tier; endocrine, emerging tier). This is research with sources, not medical advice.

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 Diisodecyl Phthalate safe in heated food packaging?

Food processing2 uses researched6 sourced claims

Where it turns up: plasticizer migrating from food packaging. Detox My Life researched diisodecyl phthalate under 2 different uses, because the same substance means something different in each. 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 (3)

ConsensusRestrictedconfidence 100%

The European Union has set a maximum specific migration limit (SML) from food contact materials of 9 mg/kg food for the sum of diisodecyl phthalates and diisononyl phthalates. DIDP is generally not to be used in materials that come into contact with fatty foods or foods meant for infants or young children in the EU.

Why here: DIDP is used in food contact materials, and these restrictions are in place to limit consumer exposure through food.
What would have to be true: Human dietary exposure to DIDP from food contact materials, limited by the SML of 9 mg/kg food (sum of DIDP and DINP).

Diisodecyl phthalate (DIDP) has been found to have the potential to harm the liver, with the European Food Safety Authority (EFSA) setting its Tolerable Daily Intake (TDI) of 150 µg/kg body weight per day based on liver effects.

Why here: DIDP can migrate from food contact materials into food, leading to dietary exposure.
What would have to be true: Human dietary exposure to DIDP from food contact materials.

Diisodecyl phthalate (DIDP) is listed under California's Proposition 65 as a substance known to the state to cause reproductive toxicity. The U.S. Consumer Product Safety Commission (CPSC) recognizes DIDP as a probable developmental toxicant, and the European Chemicals Agency (ECHA) has concluded it has developmental toxic effects. The U.S. Environmental Protection Agency (EPA) also found that DIDP has the potential to cause developmental toxicity.

Why here: DIDP is commonly used as a plasticizer in food contact materials, and it can migrate into food, particularly when in contact with heated or fatty foods, leading to dietary exposure.
What would have to be true: Human dietary exposure to DIDP from food contact materials, especially when heated or in contact with fatty foods, where migration is increased.
The other side: The European Chemicals Agency's (ECHA) Risk Assessment Committee (RAC) concluded in 2013 that DIDP does not warrant classification for reprotoxic effects under the EU's Classification, Labelling and Packaging (CLP) regulation. The European Food Safety Authority (EFSA) concluded that DIDP does not affect testosterone levels in fetuses and that current dietary exposure from food contact materials is not a concern for public health, with high consumer exposure being 1,500 times below the safe level. The US EPA did not find enough evidence to determine that DIDP affects the developing male reproductive system, known as 'phthalate syndrome'.

Diisodecyl phthalate (DIDP) is classified as a developmental toxicant.

Why here: Ingestion is a primary route of exposure for humans, particularly for women, infants, and children, through diet and dust, leading to systemic exposure.
What would have to be true: Ingestion of DIDP. Animal studies show mild maternal and developmental effects at 1000 mg/kg/d, with a No Observed Adverse Effect Level (NOAEL) of 500 mg/kg/d in rats. California prohibits DIDP in toys and childcare articles at levels greater than 0.1% if they can be placed in a child's mouth.

Diisodecyl phthalate (DIDP) has the potential to cause harm to the liver.

Why here: Ingestion is a route of exposure, and liver effects have been observed in animal studies.
What would have to be true: Ingestion of DIDP. A No Observed Adverse Effect Level (NOAEL) for liver effects of 15 mg/kg body weight per day derived from a study on dogs can be considered for humans.

EmergingEndocrineconfidence 70%

Some studies suggest that urinary metabolites of diisodecyl phthalate (DIDP) were inversely related to oocyte yield and fertilization rates in in vitro fertilization (IVF), indicating potential adverse effects on female reproductive health.

Why here: Ingestion leads to systemic exposure and metabolism, and these metabolites may interfere with reproductive processes.
What would have to be true: Human exposure to environmental endocrine-disrupting chemicals, with observed associations between urinary DIDP metabolites and reproductive outcomes in IVF.
The other side: A weight of evidence assessment conducted in accordance with European Chemicals Agency (ECHA) and European Food Safety Authority (EFSA) guidance concluded that DIDP does not demonstrate endocrine activity in in vitro assays and shows no EATS (Estrogen, Androgen, Thyroid, Steroidogenesis)-related adverse effects in animals, suggesting it is unlikely to disrupt androgen pathways during development.

Not researched here

The engine has no dossier for diisodecyl phthalate when cooked with heat, in cold food, as a finishing ingredient, on skin (left on) 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.
