What is titanium dioxide?
TiO2 is composed of one titanium atom and two oxygen atoms, and its CAS registry number is -67-7. It is quite good at scattering light, offering luminosity (what we call a high refractive index) without being toxic or reactive, allowing for intensifying the whiteness and shine of many materials in a safe manner. The shine, chromatic intensity, opacity and whiteness that it offers are unique.
TiO2&#;is considered to be chemically inert, which means that it does not react with other chemicals.
Both its melting point&#;(&#;°C / °F) and its boiling point (&#;°C / °F) are extremely high, which means that it is found in nature in a solid state and is insoluble in water even as a particle.
TiO2 Varieties
Among the existing varieties of TiO2, the most conventional forms are RUTILE, which sees the most widespread use worldwide, and ANATASE, which sees more use in the pharmaceutical, cosmetics and food industry.
Titanium Dioxide production methods
There are two methods to produce TiO2: a sulfate process and a chloride process.
In the sulfate process, the mineral is dissolved in sulfuric acid and extracted as sulfate salts, and is then subjected to hydrolysis, calcination and a milling stage, where any remnant of sulfuric acid is broken down and crystals of the required size are formed. In the chloride process, chlorine is used instead of sulfuric acid, where Rutile is transformed into titanium chloride, and the titanium chloride oxidizes, thereby obtaining it through a more affordable process.
Main Characteristics of Titanium Dioxide
The various forms of TiO2 are characterized by usually being subjected to a surface treatment that improves their properties in regard to dispersibility, coating capabilities, surface compatibility and low oil absorption. These treatments are commonly inorganic, with the use of alumina, silica and zinc.
When choosing a variant of titanium dioxide you must analyze the following:
Whiteness &#; it is important for the TiO2 not to turn yellow and to have an adequate shininess.
Dispersibility &#; that it is easy to add into the system.
Opacity &#; that it has excellent coating properties.
Oil absorption &#; that it is as low as possible.

These factors help achieve desired product performance, safety, and customer satisfaction in personal care products made from titanium dioxide powder.
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?
- 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.
- 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.
- 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.
- 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.
- 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.
- Color Consistency: Quality pigments should provide consistent color across different batches. Batch specifications and color matching can help confirm this.
- Processing Method: Quality is also associated with methods used during pigment production, such as post-processing treatments that enhance dispersion stability.
- Regulatory Compliance: Ensure safety and sanitary guidelines are observed on labels or technical data sheets before usage.
Having examined these criteria, I can assess the quality of titanium dioxide pigments before making any decisions about their application in cosmetics or coatings.
What Particle Size Should I Look for in Titanium Dioxide?
As for the particle size of titanium dioxide (TiO&#;), this largely depends on its intended usage. For instance, a range between 200-300 nm is typically recommended in cosmetics since this allows adequate UV protection while still maintaining easy application onto skin surface. Contrary to this position, industrial applications such as paint need slightly larger particles, which may measure from 300-500 nm, to achieve increased opacity and coverage.
I came up with several technical parameters that are important in evaluating particle size as I was researching through the top 10 websites:
- Average Particle Size: The smaller the average particle size (below 200 nm), the more desirable it is for cosmetic formulations due to higher skin absorption and light scattering abilities.
- Width of Distribution: A reduced range of sizes facilitates consistency in application; the span ratio should be less than 1.5.
- Surface Area: According to specific surface area measurements (BET method), a higher surface area (greater than 50 m²/g) can yield more pigment effectiveness in various applications.
- Aspect Ratio: Ratios close to 1, on the other hand, enhance aesthetic appeal and functionality by enhancing dispersibility in formulations.
If I pay attention to these factors, I can select titanium dioxide that meets my project&#;s quality and performance specifications.
