What Is the Difference Between Nano- And Non-nano-Titanium Dioxide?

The particle size distinguishes nano- from non-nano-titanium dioxide, significantly affecting their characteristics and applications in cosmetic products and personal care items.

1. Particle Size:

• Nano Titanium Dioxide: Particles that are typically smaller than 100 nanometers. Such small size allows for greater transparency of formulations, especially sunblock ones, while achieving effective UV filtration.
• Non-Nano Titanium Dioxide: Particles larger than 100 nanometers. These tend to be more opaque, providing a white cast on the skin, which may be desirable in some but limits them to cosmetic use only.

2. UV Protection:

• Both forms act as effective UV filters; however, nano titanium dioxide is less visible on the skin yet maintains a high SPF value compared to non-nano forms. Due to their large sizes, non-nano ones offer a stronger immediate UV barrier, but they might also not blend into the skin.

3. Absorption through the skin:

• The size of nano titanium dioxide has shown reduced skin permeation, making it possibly safe for topical use. Similarly, non-nano titanium dioxide does not penetrate the layers of the skin as well but its particle size is larger so people feel more protected from its impact.

4. Regulatory and Safety Aspects:

• Regulatory agencies have different judgments about both forms; thus, nano titanium dioxide is often put to a more severe test because its toxicological concerns may be applicable in some formulations. Moreover, non-nano titanium dioxide is typically seen as conventional, so it might not come under close scrutiny, though it is still subject to safety regulations.

Technical Parameters:

• Refractive Index: Although it refracts light with an index range of approximately 2.7, this chemical component can show greater transparency if it&#;s nano. As it&#;s been used in formulating products, it refracts light with an index range of approximately 2.7.
• Purity Standards: Both types require high purity levels, but nanotechnology might demand further processing to ensure product uniformity.

Therefore, when deciding whether to use nano or non-nano titania in cosmetics, such factors will influence formulation approaches and end-use properties, directly impacting efficacy.

How to Check the Quality of Titanium Dioxide Pigment?

1. Pigment Type: Determine if they are made up of either Nano or Non-Nano particles, which largely affects how they disperse and are applied. Typically, nanoparticles are cleaner and transparent, while conventional alternatives are more traditional.
2. Purity Levels: Look at manufacturers who indicated purity standards that should be adhered to since high-grade pigments must contain at least 99% pure TiO2. Impurities will affect your pigment performance and stability.
3. Refractive Index: Both forms usually have a refractive index of around 2.7. A higher refractive index indicates better light scattering properties and is important for paints and coatings.
4. Particle Size Distribution: An even distribution of particle sizes ensures uniform application and improves aesthetics. The size of the particles can also affect opacity and tint strength.
5. Opacifying Power: Opacity refers to how much pigment hides underlying surfaces. I found that the higher the opacifying power, the less pigment required for coverage, making it more cost-effective.
6. Color Consistency: Quality pigments should provide consistent color across different batches. Batch specifications and color matching can help confirm this.
7. Processing Method: Quality is also associated with methods used during pigment production, such as post-processing treatments that enhance dispersion stability.
8. Regulatory Compliance: Ensure safety and sanitary guidelines are observed on labels or technical data sheets before usage.

Titanium dioxide (TiO&#;) is a widely utilized compound in various industries, appreciated for its unique optical, physical, and chemical properties. It naturally occurs in three polymorphic forms: anatase, rutile, and brookite. Among these, anatase and rutile are the most significant for industrial applications, while brookite is rarely used due to its instability. This article will discuss the key differences between anatase and rutile, highlighting their structures, properties, and applications.

Crystal Structure and Stability

Both anatase and rutile belong to the tetragonal crystal system but differ in their lattice structures and stability.

• Anatase: This polymorph has a more open crystal structure, with a unit cell containing four TiO&#; molecules. Its crystal lattice is less compact, resulting in lower density. Anatase is stable at room temperature but transforms into a more stable phase at elevated temperatures, typically around 730°C. This transformation is irreversible and exothermic, highlighting the higher thermodynamic stability of the final phase.
• Rutile: Characterized by a denser and more compact crystal structure, each unit cell contains two TiO&#; molecules. This close-packed arrangement results in a higher density and greater stability. It is the most thermodynamically stable form of TiO&#;, and both anatase and brookite convert into this stable phase upon heating.

Physical Properties

--Density and Hardness

The relative density of anatase ranges from 3.8 to 3.9 g/cm³, and its Mohs hardness is between 5.5 and 6.0. The lower density and hardness make anatase less durable than rutile.

With a relative density of 4.2 to 4.3 g/cm³, rutile is denser and more compact. Its Mohs hardness ranges from 6.0 to 7.0, making it more suitable for applications requiring higher durability and wear resistance.

--Dielectric Constant

The dielectric constant of anatase is around 48, which is significantly lower than that of rutile. This lower dielectric constant limits its use in applications that require high dielectric properties.

Rutile has a much higher dielectric constant, averaging around 114. This high dielectric constant, coupled with its stability, makes it ideal for electronic applications.

Optical Properties

--Refractive Index

The refractive index of a material determines its ability to bend light, and TiO&#; is known for having a very high refractive index, which is beneficial for optical applications. The refractive index of anatase is approximately 2.55. While high, it is still lower than that of rutile.

Rutile boasts an even higher refractive index, around 2.71, making it exceptionally effective in applications requiring maximum light scattering and opacity.

--Scattering Power

The light scattering ability of TiO&#; is crucial for its use as a pigment in paints, coatings, and other materials. Despite having good light scattering properties, anatase's lower refractive index means it is less effective than rutile.

With its higher refractive index, rutile provides superior light scattering, enhancing opacity and brightness in applications like paints and coatings. This makes it the preferred choice for white pigments.

Electrical Properties

--Conductivity

Titanium dioxide acts as a semiconductor, with its electrical conductivity influenced by temperature and oxygen vacancies. Generally, anatase exhibits lower electrical conductivity. It is less sensitive to temperature changes compared to rutile.

Rutile&#;s electrical conductivity increases significantly with temperature. At around 420°C, its conductivity can increase by several orders of magnitude, making it valuable in electronic components such as ceramic capacitors. This sensitivity to temperature and oxygen content makes it useful in sensing applications.

Applications

Both anatase and rutile have distinct applications based on their respective properties.

1. Anatase

• Photocatalysis: Anatase is widely used in photocatalytic applications due to its higher reactivity under UV light. It is effective in degrading organic pollutants, making it useful for air and water purification systems, self-cleaning surfaces, and antimicrobial coatings.
• Solar Cells: Due to its photoactive properties, anatase is employed in dye-sensitized solar cells to enhance efficiency.

2. Rutile

• Pigments: Its high refractive index and superior light scattering make it ideal for use as a white pigment in paints, plastics, and papers. It provides excellent opacity and brightness.
• Optical Components: It is used in the production of optical components, such as lenses and coatings, due to its high refractive index.
• Electronics: Its high dielectric constant and electrical conductivity under high temperatures make rutile suitable for electronic devices, including capacitors and varistors.
• High-Temperature Applications: Its stability at high temperatures makes it suitable for ceramic glazes, refractory materials, and other high-temperature applications.
