Titanium Dioxide UV Protection Testing in Cosmetics
Testing the titanium dioxide (TiO₂) content and its effectiveness as a sun protection factor is crucial for cosmetics manufacturers. This testing ensures that products meet regulatory standards, provide effective sunscreen performance, and maintain consumer trust. As quality managers and R&D engineers, you must understand how to measure TiO₂ in terms of UV absorption and ensure that it meets the necessary criteria.
Titanium dioxide is a widely used ingredient in sunscreens due to its ability to absorb ultraviolet (UV) radiation effectively. However, not all forms of titanium dioxide are equally effective or suitable for cosmetic products. For instance, nano-sized TiO₂ particles can offer superior UV protection but may also present challenges related to skin absorption and potential health concerns.
The testing process involves several steps: sample preparation, measurement using spectrophotometric techniques, and evaluation against international standards such as ISO 21775 for sunscreen products. This service ensures that the titanium dioxide in your cosmetic formulations is safe, effective, and compliant with regulatory requirements.
Our approach to TiO₂ testing focuses on providing accurate results through advanced instrumentation and experienced technicians who specialize in this field. We use cutting-edge technology like UV-Vis spectrophotometers to analyze the samples accurately. The test process typically involves dispersing the titanium dioxide particles into a solution, then measuring their absorbance at specific wavelengths.
Here are some key aspects of our testing service:
- Analysis of both nano and non-nano TiO₂ forms
- Determination of the particle size distribution using dynamic light scattering (DLS)
- Evaluation of UV absorption properties through spectrophotometric analysis
- Compliance with international standards like ISO 21775
We offer comprehensive reports that detail our findings, including any deviations from expected values or regulatory limits. These reports are essential for ongoing product development and quality assurance.

The results of this testing are invaluable for quality managers, compliance officers, and R&D engineers. They provide critical insights into the performance of TiO₂ in sunscreen formulations, ensuring that products meet regulatory requirements while delivering optimal UV protection to consumers.
Scope and Methodology
| Step | Description |
|---|---|
| Sample Preparation | Disperse the TiO₂ particles in a suitable solvent for analysis. |
| Spectrophotometric Measurement | Determine UV absorption at specific wavelengths using an advanced spectrophotometer. |
| Particle Size Analysis | Analyze particle size distribution via dynamic light scattering (DLS). |
| Compliance Check | Evaluate results against relevant international standards and guidelines. |
The testing process begins with careful sample preparation. The TiO₂ particles are dispersed in a solvent, which allows for accurate measurement of their UV absorption properties. This step ensures that the particles are evenly distributed and ready for analysis.
Next, we use an advanced spectrophotometer to measure the UV absorption at specific wavelengths. This equipment is crucial for determining how well the TiO₂ particles block different types of UV radiation (UVA and UVB). The results from this step provide essential data on the sunscreen's effectiveness.
The particle size distribution is also analyzed using dynamic light scattering (DLS) technology. Particle size plays a significant role in the performance of titanium dioxide as a sun protection factor. Smaller particles can offer better coverage but may raise concerns about skin absorption and potential health risks.
Finally, all results are compared against international standards such as ISO 21775 to ensure compliance with regulatory requirements. This step is vital for ensuring that the product meets both safety and performance criteria.
