Zhongqi Toothpaste Grade Silica: The Quality Choice for Oral Care Raw Materials

Zhongqi Toothpaste Grade Silica: The Quality Choice for Oral Care Raw Materials

The global market for oral care products is experiencing a demand upgrade for quality. Zhongqi (Guangdong) Silicon Materials Co., Ltd., having深耕 silicon materials for over a decade， has developed toothpaste-grade silica that meets the QB/T2346-2015 standard. It serves over 100 oral care brands both domestically and internationally.

Brand Strength and Production Assurance

The company's headquarters is located in Zengcheng District， Guangzhou. It has two intelligent production bases in Guangdong and Shandong， equipped with fully automated production lines and precise testing equipment. It strictly follows the QB/T2346-2015 standard and establishes a three-level control system of "raw material traceability - process quality control - finished product re-inspection" to ensure consistent batch quality.

Product Series and Core Advantages

It builds three matrices： friction type， thickening type， and comprehensive type. All are white uniform powders with excellent dispersibility and biological safety， without skin or mucous membrane irritation， and suitable for various formulations.

Friction type： Efficient cleaning， gentle enamel protection

Model ZLDIO-T100/T101/T102， with a particle size of 10-14 μm， specific surface area of 110 m²/g， absorption volume ≤ 30 ml/20 g， purity ≥ 98%. The plaque removal rate is ≥ 92%， enamel wear value ≤ 2.0 mg (far superior to the industry standard of 3.5 mg). The flagship ZLDIO-T101 is a high-end whitening toothpaste core material with an ultra-low absorption volume of 16.5 ml/20 g and a high purity of 98.4%.

Thickening type： Stable system， smooth texture

Model ZLDIO-T103/T104/T105， with a three-dimensional network structure achieving "low addition high thickening"， absorption volume ≥ 42 ml/20 g， with 1%-3% addition amount， viscosity can be stabilized at 80，000-120，000 mPa·s. No sedimentation after 30 days at 25℃， improving the cream's smoothness. The star model ZLDIO-T103 has an absorption volume of 53.0 ml/20 g and a transmittance of 97.1%， making it an exclusive raw material for transparent/precious toothpaste.

Comprehensive type： Dual effects， adaptable to multiple uses

Model ZLDIO-TY2， with a composite modification technology integrating cleaning and thickening functions， particle size adjustable from 8-15 μm， specific surface area 140-200 m²/g， absorption volume 30-42 ml/20 g. Purity ≥ 98%， whiteness 99.6% (CIE standard)， suitable for probiotic， traditional Chinese medicine extract， etc. composite formulations.

Strict Testing and Safety Assurance

Establish a "full-item testing + third-party re-inspection" system. Key indicators far exceed industry requirements：

• Physical and chemical indicators： pH 6.0-8.5， 325 mesh below ≥ 98%， 105℃ volatile matter ≤ 10.0%， lead ≤ 15 mg/kg (2 times higher than national standards)， arsenic ≤ 3 mg/kg (food grade standard)；

• Hygiene indicators： colony count ≤ 200 cfu/g， mold and yeast ≤ 100 cfu/g， no pathogenic bacteria detected， in line with "Cosmetics Safety Technical Specifications".

Each batch of products comes with an inspection report， indicating production information， with a shelf life of 12 months.

Application Scenarios and Usage Guidelines

• Application recommendations： Whitening and brightening type (ZLDIO-T101/T102， added 15%-25%， brightening effect increases by 40%+)； Thick and smooth type (ZLDIO-T103/T104/T105， added 1%-3%， smoothness improves by 30%)； Multi-functional composite type (ZLDIO-TY2/T100， added 8%-15%)； Granular type (ZLDIO-T104/T105， suspension rate ≥ 98%)；

• Packaging and storage： 10/20 kg composite aluminum-plastic bags， transported at 0-40℃， stored at ≤ 30℃ in a dry and ventilated place (humidity ≤ 60%)；

• Operating instructions： Wear dust-proof masks and nitrile gloves. Rinse skin/eyes with water for 15 minutes if contact occurs. Zhongqi adheres to the concept of "building on quality and promoting innovation", with an annual R&D investment of no less than 5%. It focuses on cutting-edge areas such as biocompatible silicon materials and collaborates with partners to promote the high-quality development of the oral care industry.
