Key Features
- Nano-scale particle size: approximately 45 nm average particle size as described in the TDS.
- Rutile crystal form: rutile content ≥98%, with a reported typical value of 100%.
- Surface-treated powder: aluminum hydroxide treatment, or combined aluminum hydroxide and zirconium hydroxide treatment.
- Typical TiO₂ content of 88.5%: reported separately from the specified minimum of 80%.
- Optical characteristics assessed against a standard: transparency, frontal golden tone and oblique blue tone are listed in the TDS.
- Bilingual technical documents: English and Chinese TDS and SDS documents are available below.
Formulation Selection and Sample Evaluation
When evaluating CTNR-1101, please share your intended application, formulation medium, dispersion process and target optical performance. These details help us discuss the grade against your requirements and coordinate the relevant technical information.
Useful points to assess in your own formulation include:
- Compatibility with the formulation medium and other ingredients
- Dispersion under your actual mixing or milling conditions
- Transparency and colour appearance at the intended addition level
- Viscosity and processing behaviour
- Stability and final performance under the intended conditions of use
Compare samples under the same formulation and processing conditions before commercial use. The stated average particle size alone does not establish dispersion quality or final performance in a finished product.

Ranges and typical values are presented separately. Typical values are reference data and should not be interpreted as guaranteed batch values. Optical characteristics are assessed against the standard sample. A dash indicates that no separate value or numerical range is stated.
Surface Treatment and Composition
CTNR-1101 consists primarily of titanium dioxide. Its surface treatment uses aluminum hydroxide, or a combination of aluminum hydroxide and zirconium hydroxide. The reported typical contents are 10.0% aluminum hydroxide and 1.0% zirconium hydroxide.
For formulation assessment, review both the titanium dioxide content and the surface-treatment composition rather than comparing grades by particle size alone.

Frequently Asked Questions
Is CTNR-1101 anatase or rutile titanium dioxide?
CTNR-1101 is a nano rutile titanium dioxide. The TDS lists a rutile content of at least 98%, with a typical value of 100%.
What is the particle size of CTNR-1101?
The product description states an average particle size of approximately 45 nm. Dispersion and particle agglomeration in a finished formulation should be evaluated under your actual processing conditions.
What surface treatment does CTNR-1101 use?
The TDS describes aluminum hydroxide treatment, or combined aluminum hydroxide and zirconium hydroxide treatment. Typical contents are listed as 10.0% and 1.0%, respectively.
What is the TiO₂ content of CTNR-1101?
The specified minimum TiO₂ content is 80%, and the reported typical value is 88.5%. These figures represent a requirement and a typical value, respectively.
Can CTNR-1101 replace my current nano titanium dioxide?
Replacement suitability depends on composition, surface treatment, dispersion, addition level and the performance required in your finished product. Compare samples in the same formulation before deciding on a substitution.
