ZLDIO-TY2 All-in-One Toothpaste Grade Silica
Product Description
ZLDIO-TY2 is a self-developed all-in-one toothpaste-grade silica produced through a refined precipitation process. It strictly complies with QB/T 2346-2015 Oral Care Products - Silica for Toothpaste industry standard, and simultaneously meets the core global oral care raw material compliance requirements including GB 22627-2022, Safety and Technical Standards for Cosmetics, as well as FDA and EFSA regulations. Balancing three core properties of mild cleaning, moderate abrasion and thickening stabilization, it exhibits excellent compatibility with mainstream toothpaste raw materials such as fluorides, plant extracts, flavors and sweeteners. As a versatile abrasive base suitable for most conventional functional toothpastes, it offers outstanding cost performance and can meet the large-scale production needs of both domestic and export toothpastes. The product performance is based on our own R&D and production standards and has no association with any other brand models.

Application Scenarios
It is suitable for mainstream toothpaste categories including ordinary cleaning toothpaste, basic whitening toothpaste, breath-freshening toothpaste, anti-sensitive toothpaste base and compliant children's toothpaste, and is compatible with high-speed automatic toothpaste production lines. It can optimize paste formability, thixotropy and dispersibility, achieve a balance between mild cleaning and low tooth enamel abrasion, and has good compatibility with active ingredients in formulas without affecting the taste, fragrance, shelf stability and core efficacy of toothpaste. (The actual use effect varies due to customers' formula systems, production processes and production equipment. The final result shall be subject to customers' test results.)
Core Advantages
• Balanced Comprehensive Performance: It balances cleaning power, low abrasion and thickening stabilization effects, adapting to most conventional functional toothpaste formulas without major adjustments to the formula system.
• Precise Particle Size Control: With ≥98% residue through 325 mesh sieve, it produces a fine paste without gritty sensation, exhibits excellent dispersibility, is not prone to caking during the toothpaste making process, can shorten homogenization time and improve production efficiency.
• High-Purity Refining Process: It has high silicon dioxide content and impurity content far below standard limits. It has excellent compatibility with mainstream anti-caries fluorides such as sodium monofluorophosphate and sodium fluoride, and can stabilize the fluoride ion retention rate in the formula system.
• Ultra-High Whiteness: The typical batch measured whiteness is 99.6%, which does not affect the color and appearance of toothpaste paste and is suitable for transparent/semi-transparent toothpaste formula systems.
• Full-Process Hygiene Control: Heavy metal and arsenic contents are far below standard limits, no pathogenic bacteria are detected, and microbial indicators are excellent, meeting all compliance standards for oral care raw materials at home and abroad.
• Global Export Support: It supports the production of export toothpastes for mainstream markets worldwide, provides stable batch supply, and offers customized fine-tuning services for indicators such as particle size and water absorption according to customers' formula requirements.
Packaging, Storage and Transportation
• Food-grade PE inner lining + thickened moisture-proof composite film packaging, which is anti-pollution, anti-moisture and anti-caking, suitable for all-scenario transportation including land, sea and air.
• Store in a sealed manner in a cool, dry, ventilated and clean place, away from odors and pollution sources. It is not a hazardous chemical.
• Support customization of multi-language shipping marks and compliance labels in Chinese, English, Japanese, Korean, etc., adapting to the import regulatory requirements of different countries and regions.
Frequently Asked Questions
Q: How is the compatibility of this product with fluorides? Will it affect the anti-caries effect of toothpaste?
A: This product is high-purity amorphous silica with low impurity content and controllable free silanol content. It has excellent compatibility with mainstream anti-caries fluorides such as sodium monofluorophosphate and sodium fluoride, can stabilize the fluoride ion retention rate in the formula system, and does not affect the exertion of toothpaste's anti-caries efficacy.
Q: Is it compatible with high-speed automatic toothpaste production lines?
A: Yes. This product has uniform particle size with ≥98% residue through 325 mesh sieve and excellent dispersibility. It can disperse quickly and uniformly during the toothpaste making process, is not prone to caking and hard particles, can shorten homogenization and defoaming time, adapts to high-speed continuous toothpaste production equipment, and improves production efficiency and batch stability of the paste.
Q: Does it meet the raw material use standards for children's toothpaste?
A: All indicators of this product comply with QB/T 2346-2015 Oral Care Products - Silica for Toothpaste industry standard, GB 22627-2022 national standard, Safety and Technical Standards for Cosmetics and relevant raw material safety requirements for children's cosmetics. It can be used in the production of children's toothpaste formulas within the compliant dosage range.
Q: Is the hygiene and safety of the product guaranteed?
A: This product strictly follows the hygiene control standards for oral care raw materials. Heavy metal and arsenic contents are far below standard limits, and pathogenic bacteria such as thermotolerant coliforms, Pseudomonas aeruginosa and Staphylococcus aureus are not detected. Its microbial indicators fully meet the safety requirements for oral care raw materials at home and abroad.
