Toothpaste Grade Hydrated Silica

Product Specification

Feature

INCI name Hydrated Silica for overseas labeling/registration; controlled particle size and stable abrasion; white powder, good dispersion; customizable by RDA/oil absorption for mainstream paste systems. Toothpaste Grade Silica Toothpaste-grade silicon dioxide · Abrasive & thickening grades 1. Compliant with major global standards Meets ISO 11609, EU Cosmetic Regulation EC 1223/2009 and China GB 8372. Heavy metals (lead, arsenic, mercury) are strictly controlled. CoA, MSDS and raw-material documentation available. 2. Controlled abrasion, gentle on enamel Abrasive grades cover low, medium and high RDA values — from mild children's grades (RDA 30–60) to adult daily care (RDA 70–120) and whitening grades (RDA 130–180). We match the RDA to your formulation, avoiding over-abrasion. 3. Thickening and structure-building Thickening grades give good thixotropy: the paste stands up on the brush without collapsing, does not drip, and flows smoothly during filling and brushing. 4. Fluoride-friendly Chemically inert. Does not react with sodium monofluorophosphate (MFP) or sodium fluoride (NaF). Fluoride content stays stable through shelf life. 5. Transparent toothpaste grades Refractive index (nD) precisely matched to glycerin / sorbitol / water systems (around 1.45–1.47). Gives a clear, non-cloudy gel that looks premium on the shelf. 6. High whiteness, no yellowing Powder whiteness ≥ 95%. Does not yellow or discolor over time, and stays stable with flavors, colors, herbal extracts and actives. 7. Broad formulation compatibility Works well with SLS/SLES, glycerin, sorbitol, PEG, xylitol, saccharin sodium, preservatives, calcium carbonate, herbal ingredients and fluoride. 8. Batch-to-batch consistency Particle size (D50), RDA, oil absorption, pH and moisture vary little between batches — smooth from lab sample to ton-scale production. Recommended direction by your product: For adult daily toothpaste, use a standard abrasive grade blended with thickening grade. For whitening toothpaste, use a higher-abrasion grade. For children's and sensitive-gum toothpaste, choose low-RDA grades with thickening as the main base. For clear gel toothpaste, use the transparent grade with matched refractive index and low RDA. Talking points for customers: Say "helps gently clean" and "helps remove surface stains" — do not use treatment claims such as "treats gingivitis", "rebuilds enamel" or "eliminates plaque". Whitening should be framed as "helps reduce extrinsic stains", not as a guaranteed shade result. When exporting, lead with three points: **controllable RDA, fluoride compatibility, and ISO 11609 compliance**.
