In the field of oral hygiene care products and functional materials, silica products with chemical inertness and structural designability are becoming key materials for regulating the performance of toothpaste and enhancing industrial functions. The product toothpaste silica series 520A launched by our company, as an amorphous powder functional additive, demonstrates significant application value in areas such as toothpaste friction cleaning, paste rheology regulation, and industrial functional filler materials, providing a systematic selection of silica products for the oral care and materials industries.


1. Core Characteristics and Series Design


The product toothpaste silica series 520A is an amorphous powder without odor, insoluble in water or acid, chemically inert, and has good compatibility with fluoride and other raw materials. The structure and particle size of silica can be controlled by production conditions. For different types of toothpaste, three products are produced: friction type, mixed type, and thickening type.


The friction type product has a silica content of no less than 95%, a whiteness of no less than 93%, and a 320-mesh sieve content of no less than 98%. The water absorption value is 17 to 20 milliliters per 20 grams. This type of product focuses on cleaning performance, has a high friction value, and can effectively remove stains from teeth, suitable for the production of high-end whitening toothpaste. The mixed type product has a silica content of no less than 98%, a whiteness of no less than 98%, a 320-mesh sieve content of no less than 99%, and a water absorption value of 30 to 42 milliliters per 20 grams. It has excellent comprehensive performance and combines both cleaning ability and thickening effect. The thickening type product has a silica content of no less than 98%, a whiteness of no less than 98%, a 320-mesh sieve content of no less than 99%, and a water absorption value of 45 to 60 milliliters per 20 grams. It mainly serves to improve the consistency and stability of the toothpaste paste.


2. Application Value in the Toothpaste Industry


The core application field of the product toothpaste silica series 520A is the toothpaste industry. As a key raw material for the toothpaste formula, this series mainly functions in friction cleaning and paste rheology regulation.


The friction type product has a frictional cleaning effect on teeth, effectively removing dental plaque and surface stains, achieving a balance between effective cleaning and tooth enamel protection. The thickening type product mainly improves the consistency and stability of the toothpaste paste, usually not used alone but combined with other abrasives for toothpaste production. The mixed type product combines some characteristics of the friction type and thickening type, when combined with calcium carbonate and other abrasives, can improve the appearance and dispersion of the toothpaste paste. This product has good compatibility with fluoride, helping to maintain the stability of fluoride efficacy in the toothpaste.


3. Expansion of Industrial Applications


Based on the chemical inertness and controllable microstructure of the product, this product also shows potential for application in the industrial field. The friction type product can be used in the friction material industry, such as the production of brake pads and clutch plates, effectively enhancing the friction coefficient in high-temperature and high-pressure conditions and maintaining stable performance. The mixed type product can be used in the coating industry as a body pigment to improve the rheological properties, leveling performance, and anti-settling performance of coatings, and can also be used in ink production to improve the coloring strength and adhesion. The thickening type product can be used in the cosmetics industry as a thickening agent and suspension agent to regulate the viscosity of emulsions, creams, and other products.


4. Quality Assurance and Industry Standards


The product toothpaste silica series 520A has been tested and meets the requirements of the Chinese Light Industry Industry Standard QB/T2346-2015. In terms of sensory indicators, the product is a white powder, visually free of impurities. In terms of physical and chemical indicators, strict testing standards have been established for key indicators such as silica content, whiteness, pH value, undersize particles, volatile matter, ash loss on ignition, water absorption value, sulfate content, chloride content, sulfide, heavy metal content, arsenic content, and total bacterial count, to ensure that the products meet the safety requirements for oral cleaning and care products.


V. Product Value and Market Positioning


The 520A series of product toothpaste silica used in the production process has established a strict quality control system. Key indicators such as product content, whiteness, pH value, particle size distribution, and water absorption value are subject to full-process testing to ensure consistency and reliability between batches. As the toothpaste industry continues to develop towards efficacy and differentiation, the demand for specialized silica products that combine cleaning performance and paste stability is steadily increasing. This product, with its series of functional designs including friction type, mixed type, and thickening type, good compatibility with fluoride, and quality assurance in line with industry standards, is becoming an important raw material option in the field of oral cleaning and care products, providing strong raw material support for the functional upgrade and quality improvement of toothpaste products.
