PRODUCT DETAILS
1. Product Advantages
This product is a polishing‑aided silica specially developed for toothpaste, engineered for fine tooth polishing, surface stain removal and brightening. It complies with GB/T 32673‑2016 and FDA standards for oral‑care raw materials. Featuring uniform particle size, high sphericity and smooth particle edges, it delivers core properties of mild abrasion, superior polishing performance and low dentin wear. It finely polishes micro‑stains, dental plaque and surface deposits without damaging tooth enamel, smoothes micro‑scratches on tooth surfaces, and improves tooth gloss and translucency.
It can be compounded with primary abrasives to optimize the overall abrasive system and enhance the stain‑removing and brightening efficacy of toothpaste. It also ensures a smooth paste texture with no gritty sensation, and is suitable for various whitening and polishing‑formula toothpastes.

3. Application Scenarios
Widely used in whitening toothpaste, polishing‑protection toothpaste, stain‑removal toothpaste for tobacco/tea stains, post‑treatment dental polishing products and high‑end brightening toothpaste. As a polishing auxiliary abrasive, it works together with primary abrasives to refine abrasive particles, eliminate superficial pigment deposits and soft deposits, polish tooth surfaces and reduce micro‑scratches for natural bright and translucent teeth. Its smooth particles deliver comfortable mouthfeel without harsh friction. Non‑harmful to enamel, it is ideal for long‑term daily polishing care.
4. Manufacturer Advantages
Our proprietary fine‑powder classification technology precisely screens uniform‑size particles and removes coarse/sharp particles to guarantee fine polishing performance. Equipped with laser particle‑size analyzers and dental‑surface polishing simulation testers, we strictly control powder uniformity and polishing outcomes. Our rigorous classification‑oriented quality‑control procedure ensures ≥98 % particle‑size uniformity for each batch, free of coarse‑particle impurities.
Multi‑ten‑thousand‑ton‑level fine‑processing lines guarantee stable supply. We also provide customers with custom compounding‑ratio guidance to optimize toothpaste whitening‑polishing formulations.
5. Packaging & Shipping
- Standard Package: 10 kg / 15 kg well‑sealed valve‑mouth paper bags, free of mixed foreign particles.
- Moisture‑proof Design: Double‑layer sealed moisture‑proof packaging prevents powder caking which would impair polishing fineness.
- Storage & Transportation: Store in cool and dry conditions; handle with care. Shelf life: 24 months.
- Marking: Labels indicate polishing‑grade parameters and particle‑size indicators. Custom shipping marks are supported.
6. FAQ
Q: Does polishing‑aided silica need to be used together with primary abrasives?
A: Compound usage is recommended. It can greatly boost toothpaste polishing‑brightening performance while lowering overall abrasiveness, balancing cleaning power and enamel protection.
Q: Will its polishing effect be overly aggressive?
A: No. After precision fine classification, particles are round and smooth. It only performs gentle surface polishing. No hard coarse particles are present, so tooth enamel will not be damaged.
Q: How to control the addition dosage?
A: Normal dosage ranges from 5 % to 15 %. Our technical team can propose optimal compounding ratios according to your whitening positioning and formula system.
