Understanding the CAS Number of Titanium Dioxide: Why It Matters More Than You Think
Titanium dioxide is everywhere: in your white paint, your sunscreen, even your food additives. But behind this familiar name is a more technical anchor — the CAS number of titanium dioxide. This identifier is like a fingerprint for chemicals, essential for scientists, manufacturers, regulators, and even consumers who want to make sense of what’s inside their products.
Grasping what the CAS number means helps unlock a broader understanding of safety, regulation, and innovation surrounding titanium dioxide, a compound critical to many industries worldwide, from construction to cosmetics.
The Global Weight of the CAS Number of Titanium Dioxide
Globally, titanium dioxide is produced in millions of tons annually — the cas number of titanium dioxide connects this massive production across borders and sectors. According to the United Nations’ industrial chemical data, titanium dioxide is one of the most widely used white pigments worldwide, driving innovations especially in Asia, Europe, and North America.
But here’s the hitch: when industries and regulators talk about titanium dioxide, they often need to ensure they’re discussing the exact chemical — no confusion allowed. That’s where the CAS number, the Chemical Abstracts Service Registry Number, becomes vital. It’s the global shorthand for pinpointing titanium dioxide’s precise chemical identity.
Why is this important? Because managing hazards, ensuring compliance, and fostering innovation requires everyone to be on the same page.
What Exactly Is the CAS Number of Titanium Dioxide?
Think of the CAS number as the Social Security number for chemicals. The CAS number of titanium dioxide is 13463-67-7. It doesn’t describe the physical or chemical properties, but it uniquely identifies titanium dioxide in scientific databases worldwide.
Without it? You might confuse different chemical forms. For example, titanium dioxide can appear in several crystal forms (anatase, rutile), each with distinct properties. Having one identifier brings clarity, especially where safety or trade regulations come into play.
Key Aspects of the CAS Number of Titanium Dioxide and Its Industry Role
1. Identification and Traceability
The main use of the CAS number is to track titanium dioxide precisely in global supply chains. When a company orders or tests titanium dioxide, they specify CAS 13463-67-7 to avoid any mix-up with related compounds or impurities.
2. Regulatory Compliance
Governments worldwide, from the EPA in the USA to the European Chemicals Agency, rely on these numbers to enforce safety laws, environmental controls, and worker protections. It’s tough to regulate what you can’t consistently identify!
3. Research and Innovation
Scientists referencing the CAS number can ensure reproducibility in experiments and proper referencing, which means innovation in fields like nanotechnology, cosmetics, or even photocatalysis marches ahead without confusion.
4. Supply Chain Efficiency
For manufacturers and distributors, the CAS number streamlines logistics. It’s a shorthand that connects databases, invoices, quality certificates, and more, improving transparency and reducing delays or errors.
Mini Takeaway:
The CAS number of titanium dioxide is more than just digits. It’s a bridge linking global science, industry, and regulation — without which, the whole system of modern chemical usage might stumble.
How Is Titanium Dioxide Used Globally? A Quick Tour via Its CAS Number
Well, pretty much anywhere white pigment or UV protection is needed. Titanium dioxide’s mass production under the identifier 13463-67-7 spans continents and industries:
- Paints and Coatings: In Europe alone, over 60% of titanium dioxide produced ends up in paints and exterior coatings, prized for durability and whiteness.
- Cosmetics: Sunscreens across the US and Asia use titanium dioxide to block UV rays safely, relying on precise chemical specs governed by the CAS number.
- Food Industry: Used as an additive (commonly E171), titanium dioxide’s identity via CAS registers food-grade chemicals’ safety profiles.
- Industrial Applications: In photovoltaics, inks, and plastics, manufacturers need strict chemical traceability.
- Environmental Solutions: Titanium dioxide acts as a photocatalyst in air purifiers or self-cleaning surfaces — an emerging green technology.
One example:
In post-disaster rebuilding projects in Southeast Asia, local suppliers emphasize sourcing certified titanium dioxide linked to the CAS number to ensure materials meet safety and durability requirements — no one wants a faded or toxic building.
Advantages and Everlasting Value of Knowing the CAS Number of Titanium Dioxide
- Clarity: Removes ambiguity, ensuring all parties "speak the same language" chemically.
- Safety: Protects workers, consumers, and the environment by promoting responsible handling and use.
- Trust: Consumers and regulators lean on proper identification to build confidence in products.
- Innovation: Facilitates research by providing a stable reference point.
- Cost Efficiency: Less error means fewer wasteful batch recalls or mix-ups.
Upcoming Trends: What’s Next for Titanium Dioxide and Its CAS Number?
Frankly, the industry is buzzing around nanostructured titanium dioxide — ultrafine particles with new optical or catalytic properties. Regulations are adapting, and CAS numbers help monitor these evolving materials.
Digital tracking solutions, like blockchain integrated with CAS records, are not pie-in-the-sky ideas but real pilots improving traceability and sustainability claims globally.
Green energy pushes also spark new uses for titanium dioxide in photocatalytic water treatment and solar cells under international research programs.
Challenges and How Experts Are Overcoming Them
One persistent hurdle is differentiating between various titanium dioxide grades and crystalline phases. The CAS number alone can’t specify particle size or production method, which impacts safety and functionality.
Industry groups and ISO committees are working on supplementary identifiers and testing standards to "fill in the gaps," pairing the CAS number with lot numbers, particle specs, and full certificates of analysis.
Quick FAQ on the CAS Number of Titanium Dioxide
- Q: Why do some titanium dioxide products have multiple CAS numbers?
- A: There are different forms and derivatives of titanium dioxide. The primary CAS number for pure titanium dioxide is 13463-67-7, but mixtures or specific nanoforms may have additional identifiers.
- Q: How can manufacturers verify the CAS number on a raw material certificate?
- A: Check the material safety data sheet (MSDS) or certificate of analysis — the CAS number should be clearly stated alongside purity and grade details.
- Q: Is the CAS number linked to safety thresholds or exposure limits?
- A: Not directly, but regulatory bodies use it to catalogue chemicals and set guidelines. Specific exposure limits depend on jurisdiction and form of titanium dioxide.
- Q: Can the CAS number help in sourcing titanium dioxide internationally?
- A: Yes. Suppliers and buyers worldwide use it as a standard identifier to ensure consistent chemical identity despite language or labeling differences.
