PRODUCT DETAILS
1. Product Advantages
This product is thickening silica specially developed for toothpaste, optimized for paste formation and stabilization. It fully complies with GB/T 32673-2016, FDA and FCC standards. Featuring an ultra-high specific surface area (200–400 m²/g) and well-developed 3D network structure, it forms a stable hydrogen-bond network within toothpaste systems. A low dosage can significantly boost paste viscosity and thixotropy, delivering excellent shape retention and stand-up performance. Its oil absorption and water absorption values are controllable to adapt to toothpaste formulations with various solvent systems. It exhibits outstanding compatibility with all common toothpaste ingredients including abrasives, fluorides, sweeteners and flavors. Effectively preventing paste separation, water bleeding and hardening, it ensures storage stability of toothpaste across a wide temperature range from -10 °C to 50 °C, serving as an indispensable rheology modifier in toothpaste formulations.

3. Application Fields
It acts as a core thickener and rheology modifier for all types of toothpaste formulations. It is especially suitable for products with special requirements on paste properties, such as transparent gel toothpaste, liquid toothpaste, whitening toothpaste, children’s toothpaste and medicated toothpaste.
- For transparent gel toothpaste: builds a highly transparent gel network to achieve clear, bright paste with good shape retention.
- For liquid toothpaste: adjusts fluidity to realize easy extrusion without dripping.
- For whitening toothpaste: carries whitening active ingredients, ensures homogeneous dispersion and avoids sedimentation and phase separation.
- For medicated toothpaste: stabilizes active pharmaceutical components to extend shelf life and delivers smooth paste texture for comfortable mouthfeel.
It is normally used together with abrasive silica to build a complete toothpaste system.

6. Frequently Asked Questions
Q: What is the typical dosage of thickening silica?
A: The recommended dosage ranges from 3% to 10% in conventional toothpaste formulations, subject to formulation systems and target viscosity. Higher dosage (8%–10%) is generally required for transparent gel toothpaste, while regular paste toothpaste uses 3%–6%. Our technical team can provide precise dosage recommendations based on customers’ formulations.
Q: Will thickening silica affect the cleaning performance of toothpaste?
A: Thickening silica features fine particle size and low RDA value, mainly functioning as thickener and stabilizer with limited cleaning capacity. The cleaning effect of toothpaste is primarily undertaken by abrasive silica. Combined use of both grades satisfies paste shaping requirements as well as cleaning efficacy.
Q: How is the low-temperature stability of thickening silica?
A: The gel network formed by our product possesses excellent thermal stability. No gel breakdown or paste hardening occurs at -10 °C, and the original rheological properties can be restored after thawing, fully meeting the full-temperature storage requirements for toothpaste.
