Titanium Dioxide

Elevate your product formulations to new levels of brilliance and efficacy with our premium Titanium Dioxide CI 77891 Powder. This indispensable inorganic pigment, scientifically known as Titanium Dioxide (TiO2), is renowned globally for its unparalleled ability to impart intense white color, exceptional opacity, and reliable UV protection. Identified by its Color Index CI 77891 and CAS number 13463-67-7, our powder is a high-purity, versatile ingredient trusted across numerous industries.

The Power of Titanium Dioxide: Brightness, Opacity, and Protection Titanium Dioxide is derived from naturally occurring titanium ores and is most commonly processed into its rutile form for pigment applications due to its superior properties. As an insoluble inorganic pigment, it works by dispersing uniformly throughout a medium, offering:

• Superior Brightness and Whiteness: Achieves a pristine, brilliant white color, making it the standard for whitening and brightening agents.
• Exceptional Opacity (Hiding Power): Its high refractive index allows it to efficiently scatter light, effectively covering underlying surfaces and imparting excellent opacity.
• Reliable UV Protection: Acts as a physical UV filter, absorbing and scattering harmful UVA and UVB rays, a crucial feature in sunscreens and protective coatings.
• Chemical Inertness & Stability: Highly resistant to chemical degradation, weathering, and heat, ensuring long-lasting color and performance in challenging environments.

FDA-Approved for Broad Applications in the US Our Titanium Dioxide CI 77891 is fully compliant with U.S. regulatory standards, being FDA-approved for several key applications:

• Cosmetics: Approved as a color additive for all cosmetics, including those applied around the eye (21 CFR § 73.2575). It’s a staple in foundations, powders, eyeshadows, and sunscreens (for its UV-filtering properties).
• Drugs: Approved for coloring drugs applied externally or internally, such as in tablet coatings and capsules (21 CFR § 73.1575).
• Food: Approved as a color additive in food, not to exceed 1% by weight of the food (21 CFR § 73.575). This is a crucial distinction, as its status for food use varies globally.

Important Note on Global Regulations (EU Food Ban): It is important to be aware that while Titanium Dioxide remains FDA-approved for food in the United States, the European Union has implemented a ban on Titanium Dioxide (E171) as a food additive as of August 2022, based on the precautionary principle following an EFSA re-evaluation that could not rule out genotoxicity concerns. This ban does NOT apply to its use in cosmetics or pharmaceuticals within the EU, nor does it affect its approved status in the US. Our product’s specifications are geared towards compliant usage within the USA and other regions where it is permitted.

Diverse Industrial Applications: Beyond its critical role in cosmetics, drugs, and limited food uses (in the US), Titanium Dioxide CI 77891 is a cornerstone ingredient across a vast array of industries:

• Paints & Coatings: The leading white pigment for architectural, industrial, automotive, and protective coatings due to its opacity, brightness, and durability.
• Plastics: Used in a wide range of plastic products, from PVC pipes to consumer goods, for whitening and UV stabilization.
• Paper & Pulp: Enhances the whiteness, brightness, and opacity of paper products.
• Rubber & Ceramics: Provides color and reinforcement in rubber products and acts as an opacifier in glazes and enamels.

Quality and Safety Assurance: Our Titanium Dioxide CI 77891 Powder is rigorously tested to ensure high purity, consistent particle size, and optimal performance. When handling, always prioritize safety: while generally safe, inhalation of fine dust should be minimized by working in well-ventilated areas and using appropriate personal protective equipment (e.g., dust mask, gloves, eye protection). Store in a cool, dry place in a tightly sealed container to maintain its powder form and integrity. As an insoluble pigment, ensure thorough dispersion for optimal results.

Choose our Titanium Dioxide CI 77891 Powder for unmatched quality, regulatory compliance (in the US), and the superior performance you need to create outstanding products with brilliant white color and lasting durability.

FAQs:

Q: Is Titanium Dioxide CI 77891 approved for use in food, drugs, and cosmetics in the US? A: Yes, in the United States, Titanium Dioxide (CI 77891) is FDA-approved as a color additive for use in cosmetics, externally applied drugs, and food (limited to 1% by weight of the food). It meets the specific requirements outlined in the Code of Federal Regulations (21 CFR) for these applications and is exempt from certification.

Q: Why is Titanium Dioxide so widely used as a white pigment? A: Titanium Dioxide is highly valued for its exceptional brightness and whiteness, as well as its superior opacity or hiding power. Its high refractive index allows it to efficiently scatter light, making it incredibly effective at providing intense white coloration and covering underlying colors in various products.

Q: Are there any global differences in the regulation of Titanium Dioxide? A: Yes, there are significant differences. While FDA-approved for food in the US, the European Union (EU) has banned Titanium Dioxide (E171) as a food additive as of August 2022 due to genotoxicity concerns that could not be ruled out. However, it remains approved for cosmetics and pharmaceuticals in the EU, and for all its listed uses in the US.

Q: What are the main applications of Titanium Dioxide CI 77891? A: Beyond cosmetics (foundations, sunscreens), drugs (tablet coatings), and limited food uses (in the US), Titanium Dioxide is a primary ingredient in paints and coatings for its opacity and durability, in plastics for whitening and UV resistance, and in paper to enhance brightness and whiteness. It’s a fundamental white pigment across numerous industries.

Q: Is Titanium Dioxide harmful, especially with concerns about carcinogenicity? A: The International Agency for Research on Cancer (IARC) classifies Titanium Dioxide as Group 2B (possibly carcinogenic to humans) but this classification is primarily based on inhalation studies involving high concentrations of airborne ultrafine particles in rats. It is generally considered inert and safe when ingested or applied topically at approved levels, and when proper industrial hygiene practices are followed to avoid inhaling dust. Always minimize dust exposure.
