|---|---|
As a critical component in modern toothpaste production, it provides optimal texture control, enhances active ingredient stability, and improves mouthfeel while meeting stringent safety standards. This grade is engineered to balance viscosity regulation and foam control, ensuring smooth application and effective dispersion of fluoride, abrasives, and flavoring agents. Fully compliant with GB 22115 (National Standard of the People's Republic of China) toothpaste ingredient standards and global regulatory requirements, it delivers consistent performance in both natural and conventional oral care products.
Parameter | Specification |
Appearance | White to off-white fine powder |
Viscosity (2% solution, 25°C) | 300–1500 mPa·s |
Degree of Substitution (DS) | 0.8–1.2 |
Purity (dry basis) | ≥99.5% |
pH Value (1% solution) | 6.5–7.5 |
Heavy Metal Content | ≤10 ppm |
Moisture Content | ≤8.0% |
Oral Safety Compliance: ≥99.5% purity and ≤10 ppm heavy metals eliminate irritation risks, meeting strict global oral care regulations.
Precise Texture Control: The 300–1500 mPa·s viscosity range enables customization from gel-like to creamy textures, enhancing consumer acceptance.
Active Ingredient Stability: Protects fluoride compounds and antibacterial agents from degradation, extending product shelf life by up to 24 months.
Foam Modulation: Reduces excessive foaming while maintaining sufficient lather to distribute ingredients evenly across teeth and gums.
Toothpaste Formulations: Acts as a binder to suspend abrasives (e.g., silica) and prevent phase separation in both fluoride and fluoride-free variants.
Mouthwash Concentrates: Improves viscosity in concentrated formulas, ensuring controlled dilution and consistent active ingredient delivery.
Oral Gels: Enhances adherence to tooth surfaces in therapeutic gels, prolonging contact time for sensitive teeth treatments.
Q: Is Toothpaste Grade CMC compatible with all fluoride sources?
A: Yes, its neutral pH 6.5–7.5 and stable molecular structure ensure compatibility with sodium fluoride, stannous fluoride, and amine fluoride.
Q: What viscosity grade works best for transparent toothpastes?
A: Medium viscosity grades (800–1200 mPa·s) are ideal, as they maintain clarity while providing sufficient suspension for mild abrasives.
Key Functions & Benefits
✅ Optimal Rheology Control
• Creates smooth, non-stringy textures with consistent viscosity (adjustable 800–5,000 mPa·s).
• Prevents phase separation and ensures uniform dispersion of abrasives (e.g., silica) and actives (e.g., fluoride).
✅ Enhanced Stability
• pH-resistant (4.0–10.0): Maintains performance in fluoride, whitening, or herbal formulations.
• Salt-tolerant: Compatible with potassium nitrate (sensitivity relief) and zinc citrate (anti-tartar agents).
✅ Superior Mouthfeel
• Delivers a creamy, non-gritty texture for premium brushing experience.
• Improves foam structure without compromising rinseability.
✅ Clean-Label Compatibility
• Non-GMO & Vegan-friendly: Replaces synthetic thickeners (e.g., carbomer).
• Biodegradable: Red environmental footprint.
