Dibutyl phthalate (DBP) (84-74-2) — Where It's Found, EU RoHS Status, Consumer Guide | ProductGuru

This page indexes Dibutyl phthalate (DBP) (CAS 84-74-2) on the EU Restriction of Hazardous Substances (RoHS) Directive. It is a factual surface of public regulatory data, not a safety verdict on any specific product. Always confirm the latest status on the regulator's own register (deep link below).

What is Dibutyl phthalate (DBP)?

Dibutyl phthalate (DBP) is also referred to as: dbp, dibutyl phthalate, di-n-butyl phthalate.

This entry surfaces the public-register record for Dibutyl phthalate (DBP), a chemical substance tracked by European Commission (RoHS Directive 2011/65/EU) on the EU Restriction of Hazardous Substances (RoHS) Directive. The page does not characterise typical exposure routes, doses, or clinical effects — those are the province of the EU RoHS hazard dossier itself, which is one click away.

CAS number

The Chemical Abstracts Service (CAS) registry number for this substance is 84-74-2. CAS numbers are the universal identifier used by regulators, suppliers, and Safety Data Sheets worldwide — if you are reading a product's SDS, the CAS is the line to look at, not the trade name.

European Community (EC) inventory number: 201-557-4.

Why it's on the EU RoHS list

According to European Commission (RoHS Directive 2011/65/EU), Dibutyl phthalate (DBP) is listed under the RoHS restriction reason: Reproductive toxicant [source]

Maximum concentration value (%): 0.1.

Where it's commonly found

Our index cross-references the EU RoHS listing against ProductGuru's product catalogue (5 listings mention Dibutyl phthalate (DBP) or one of its aliases / CAS number in the product name or description). Highest-relevance examples:

• ZOYA Nail Polish, Amanda, 0.5 fl. oz. (EAN 0765011202514)
• ZOYA Nail Polish, Amanda, 0.5 fl. oz. (EAN 0765011202453)
• ZOYA Nail Polish, Brenna, 0.5 fl. Oz (EAN 0765011202248)
• ZOYA Nail Polish, Brenna, 0.5 fl. Oz (EAN 0765011202224)
• Del Sol Color Change Nail Polish, Quick Dry Lacquer That Changes Hue in the Sun, Full Size Bottle, Birthday Cake White to Yellow Glitter, 0.5 oz./15 mL — Del So (EAN 0885377311467)

These examples are surfaced from product listings whose name or description contains a term matching Dibutyl phthalate (DBP). Their inclusion here is not a safety claim; presence of a substance name in a product description can mean many things (active ingredient, declared content, certification claim, or even a 'free from' marketing claim). Use the /p/<EAN> page on each listing to inspect the full data we hold.

Regulatory status by jurisdiction

This page surfaces the EU Restriction of Hazardous Substances (RoHS) Directive entry for Dibutyl phthalate (DBP). Each jurisdiction publishes its own register and its own basis-of-listing — these registers do not automatically mirror each other, so a substance can appear on one list while being unlisted on others:

• European Union: ECHA SVHC Candidate List (REACH Authorisation) + RoHS Annex II (electrical equipment) — ECHA register
• United States (California): Proposition 65 list (carcinogens + reproductive toxins) — OEHHA register
• WHO / International: IARC Monographs cancer-hazard classification — IARC classifications
• UN multilateral treaty: Stockholm Convention on Persistent Organic Pollutants — Stockholm POPs register

What this means for you

Presence on a regulatory list does not automatically mean a substance is banned. Many SVHC substances remain legal in consumer products subject to authorisation, concentration limits, or labelling requirements. Conversely, a substance not on a list is not automatically 'safe' — the absence may reflect un-assessed status rather than a negative finding.

This page indexes regulator data. It does not tell you whether to buy, keep, or discard a specific product, and it cannot estimate your personal exposure or risk. Those questions depend on the specific product, its concentration, your usage pattern, and your individual susceptibility — none of which are captured here.

If you have a concrete concern about a specific product or occupational exposure, please consult a qualified occupational health or environmental health specialist. Public-health hotlines in many jurisdictions (e.g. national Poison Control centres, EU REACH helpdesks, OSHA in the US) are free of charge.

This page indexes publicly-listed substance hazard data. It is NOT medical, legal, or safety advice. If you have specific exposure concerns, consult a healthcare professional or environmental health specialist. Regulator registers are amended over time — always verify the current status on the agency's own site before acting.

About this substance index

ProductGuru maintains a cross-referenced index of public chemical registers from major regulators: ECHA (EU REACH SVHC + Annex XIV Authorisation list), California OEHHA (Proposition 65), the World Health Organisation's International Agency for Research on Cancer (IARC Monographs), the Stockholm Convention on Persistent Organic Pollutants, and the EU Restriction of Hazardous Substances directive (RoHS, Annex II — applies to electrical and electronic equipment). Each substance × list combination has its own page on this site, with deep links straight back to the regulator's own register so every claim can be verified in one click.

The substance pages are designed for one specific need: a consumer reading a product label, ingredient list, or Safety Data Sheet who wants to know, in plain language, what a particular chemical name means and which regulators have published a hazard finding about it. We do not editorialise; we surface the regulator's wording, link to the primary source, and — where the substance name or CAS number happens to appear in product listings in our catalogue — show a small sample of those listings so you can inspect the context for yourself.

If a substance has been added to a register, removed from a register, or moved between annexes / hazard tiers since our last ingest, the regulator's own site is authoritative — please follow the Verify on … links. Registers are updated continuously; this page refreshes its ingest on a regular schedule and automatically picks up changes. If you spot a substance we have indexed incorrectly, the fastest path is the agency's own contact form.
