Introduction of ZLDIO™ Toothpaste-Grade Silica
In summary, ZLDIO™ Toothpaste-Grade Silica is compatible with both mass-market and premium toothpaste formulations. It effectively enhances product quality and serves as a highly practical core ingredient in toothpaste production.
In today's era of increasingly sophisticated oral care products, toothpaste-grade silica has become the preferred ingredient for premium toothpaste, thus outperforming traditional fillers. ZLDIO™ toothpaste-grade silica stands out as a reliable choice in this field, offering targeted performance and adhering to strict quality control standards. It excels at catering to diverse oral care needs—from basic cleaning to teeth whitening and sensitivity relief.
I. Product Overview
ZLDIO™ Toothpaste-Grade Silica is a white powder or homogeneous dispersion slurry, with silica as its primary component (≥98% on a dry basis). Specifically formulated for toothpaste applications, it functions as a cleanser, thickener, and active ingredient carrier. It is compatible with fluoride compounds and herbal extracts, making it suitable for transparent toothpaste, children's toothpaste, and whitening toothpaste. As a food additive and pharmaceutical excipient, it is safe, non-toxic, and suitable for worry-free use.
II. Core Features
1.Effortless Teeth Cleansing & Protection: With moderate hardness, it effectively removes plaque and stains without damaging tooth enamel. An even gentler formulation is specifically designed for children’s toothpaste.
2.Excellent Compatibility & Stability: It does not react with other toothpaste ingredients, protects active components, and prevents the toothpaste from separating or clumping.
3.High Purity for Safety: Heavy metal and impurity levels are far below national standards. It boasts high whiteness and odorlessness, making it suitable even for sensitive oral cavities.
4.Versatile Customization: Controllable specific surface area enables adsorption and sustained release of active ingredients. Particle sizes can be customized to meet the requirements of various toothpaste formulations.
