Choose raw materials for kids' toothpaste: Low-abrasive silica ensures safety.
Created on 08.14
Children's primary teeth have thin enamel, and an abrasive that's too hard causes irreversible wear. Nowadays, parents' top concern when choosing kids' toothpaste is whether it's gentle and non-irritating. The kids' toothpaste market grew 7.3% in 2025, and demand for low-abrasion silica keeps climbing.
Zhongqi has been making food-grade silica for 20 years, and our low-abrasion grade specifically for kids' toothpaste has been around a long time — we're extremely strict about purity and safety. Production is in GMP-standard workshops with microbial testing on every batch. Products for children are not something we cut corners on.
We recommend ZLDIO-T115, with an RDA around 80 — gentle, enough for daily cleaning, but won't wear down primary teeth. The particles are ultra-fine, with ≥98% passing a 325-mesh sieve, so there's no gritty feel. Purity is above 98%, with heavy metals and arsenic well below national standards. It also pairs cleanly with fruit flavors and sweeteners without off-notes, offering great formulation compatibility.
Traditional calcium carbonate abrasives have relatively high hardness and certain limitations in children's formulas, while imported gentle silica products come with higher procurement costs. Our kids-specific grade offers strong value, and several domestic maternal-and-child toothpaste brands use it consistently. For selection guidance, see our kids' toothpaste raw material guide on the website.
For baby-care and kids' product lines, low abrasion is the baseline — don't skimp on this raw material.
