Titanium dioxide (airborne, unbound respirable) (13463-67-7) — Where It's Found, Prop 65 Status, Consumer Guide | ProductGuru

This page indexes Titanium dioxide (airborne, unbound respirable) (CAS 13463-67-7) on the US California Proposition 65 List. 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 Titanium dioxide (airborne, unbound respirable)?

Titanium dioxide (airborne, unbound respirable) is also referred to as: titanium dioxide, tio2, ci 77891.

This entry surfaces the public-register record for Titanium dioxide (airborne, unbound respirable), a chemical substance tracked by California Office of Environmental Health Hazard Assessment (OEHHA) on the US California Proposition 65 List. The page does not characterise typical exposure routes, doses, or clinical effects — those are the province of the OEHHA hazard dossier itself, which is one click away.

CAS number

The Chemical Abstracts Service (CAS) registry number for this substance is 13463-67-7. 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.

Why it's on the Prop 65 list

According to California Office of Environmental Health Hazard Assessment (OEHHA), Titanium dioxide (airborne, unbound respirable) is listed under the Listed endpoint(s): Listed under California Prop 65 for cancer. [source]

Listed since: 2011-09-02.

Where it's commonly found

Our index cross-references the Prop 65 listing against ProductGuru's product catalogue (3,622 listings mention Titanium dioxide (airborne, unbound respirable) or one of its aliases / CAS number in the product name or description). Highest-relevance examples:

These examples are surfaced from product listings whose name or description contains a term matching Titanium dioxide (airborne, unbound respirable). 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 US California Proposition 65 List entry for Titanium dioxide (airborne, unbound respirable). 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.

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.
