Versatile Silica — Both Abrasive and Thickener
PRODUCT DETAILS
1. Product Advantages
This product is a multi-functional abrasive-and-thickening 2-in-1 dedicated silica, breaking through the limitations of traditional single-function silica raw materials by combining the two core functions of efficient dental abrasive cleaning and paste thickening/stabilizing, strictly conforming to GB/T 32673-2016 and FDA oral-raw-material standards. Through dual-function modification process optimization, the particles are round and uniform, with a moderately controllable RDA abrasive value that effectively removes tooth-surface stains and dental plaque for a gentle cleaning effect. Meanwhile, it possesses excellent three-dimensional network-building capability, efficiently improving toothpaste viscosity and thixotropy, solving problems such as thin/soft paste, sagging, stratification and tube collapse. No additional thickener is required.

3. Application Scenarios
Widely compatible with all categories of civilian and functional toothpaste, including basic cleaning toothpaste, herbal toothpaste, fluoride anti-caries toothpaste, whitening stain-removal toothpaste and transparent gel toothpaste. A single raw material replaces the traditional dual system of abrasive silica + thickening silica, greatly simplifying formulation ratios and reducing raw-material procurement and production costs. It suits mass production in daily-chemical factories and automated pipeline production, and is compatible with high/low-temperature filling and long-term storage conditions. It is a cost-effective general-purpose toothpaste functional raw material, meeting all scenarios from small-and-medium daily-chemical factories to large-brand mass production.
4. Factory Strength
A self-developed modified 2-in-1 silica dedicated production process precisely balances the dual performance of abrasive cleaning and thickening/paste-stabilizing, eliminating the performance shortcomings of single-function raw materials. Mass production runs on a fully automated dust-free production line, with per-batch powder particle size, viscosity and RDA value highly consistent and stable without fluctuation. Equipped with multi-functional raw-material performance testers, it simultaneously verifies abrasive parameters, thickening effect and safety indicators, ensuring comprehensive product performance in one stop. It supports large-volume spot supply and formulation-debugging technical liaison, helping customers optimize formulations and reduce production costs, and is suited to long-term stable strategic cooperation.
5. Shipping & Packaging
- Standard packaging: 10 kg / 15 kg / 20 kg food-grade dedicated sealed paper bags, suitable for mass-production dosing.
- Moisture-proof design: double-layer sealed moisture-proof structure ensures powder fluffiness and stable thickening and abrasive performance.
- Storage & transportation: store in cool, dry and shaded conditions to prevent caking and loss of efficacy; shelf life: 24 months.
- Marking specifications: marked with product dual-function parameters and applicable standards; factory batch-customized packaging and foreign-trade shipping marks supported.
6. FAQs
Q: Can 2-in-1 silica fully replace ordinary abrasive silica and thickening silica?
A: Yes. This product combines both standard abrasive cleaning and paste thickening/stabilizing functions. In conventional toothpaste formulations, it can directly replace the two raw materials with a single material, simplifying the formulation and reducing costs without affecting the mouthfeel or stability of the finished toothpaste.
Q: After replacing the formulation, is it necessary to adjust the proportions of other additives?
A: No major adjustment is needed. The product has extremely strong compatibility and fits most conventional toothpaste formulations. After replacement, paste viscosity, cleaning power and stability can all meet standards normally.
Q: Will paste stratification or tube collapse occur in mass production?
A: No. The product's three-dimensional network structure is stable with excellent thixotropy. Under long-term storage and high/low-temperature conditions, the paste remains full and stable, with no stratification, sagging or tube collapse.
