100 New FAQs with Answers (English Version)
For General-Purpose Precipitated Silica (Core: Food / Oral Care / Pharma / Cosmetics; Secondary: Industrial / Feed), fully expanded for Brazilian market demands, with no overlap with the previous 50 FAQs.
1. Production Process & Quality Control
Q1: What is the difference between your precipitated silica and fumed silica? A: Our product is wet-process precipitated silica produced via sodium silicate acidification. It features wider particle size tunability and better cost performance for large-volume applications. Fumed silica is made via high-temperature hydrolysis with finer primary particles and a higher price, mainly for high-end thickening scenarios. Our general-purpose grade covers most mainstream demands with higher cost efficiency.
Q2: What key quality control points are set during the production process? A: We implement full-process quality control covering raw material inspection, reaction parameter monitoring, online particle size detection, whiteness testing, heavy metal and microbial detection, and final batch inspection. Key parameters such as pH, concentration and reaction time are strictly monitored in real time to ensure product consistency.
Q3: How do you ensure traceability of each batch of products? A: Each batch is assigned a unique batch number, with complete records covering raw material source, production process parameters, testing data, packaging time and outbound logistics. The full chain from raw material to finished product is traceable, and original records can be provided upon request.
Q4: What is the production environment standard for food/pharma grade silica? A: The production workshop for food and pharmaceutical grade products follows GMP management specifications, with closed dust-free production lines, regular environmental microbial testing, and strict personnel access management to avoid cross-contamination.
Q5: Do you use recycled raw materials in production? A: No. All raw materials are virgin-grade sodium silicate and sulfuric acid from qualified suppliers. No recycled or waste raw materials are used, to ensure the stability and safety of high-purity products.
Q6: How do you control the particle size distribution of the product? A: Particle size is precisely controlled by adjusting reaction temperature, material concentration, stirring speed and reaction time during the precipitation process. We also use graded crushing and classification processes to achieve narrow particle size distribution and reduce oversized particles and fine powder.
Q7: What testing equipment is equipped in your QC laboratory? A: Our laboratory is equipped with a laser particle size analyzer, BET surface area tester, whiteness meter, atomic absorption spectrophotometer (for heavy metals), microbial culture system, pH meter and oil absorption tester, covering all routine testing items.
Q8: Is production wastewater treated and discharged in compliance? A: Yes. Production wastewater is treated through neutralization, precipitation, filtration and other processes, and discharged after meeting national environmental protection standards. We hold complete environmental protection qualifications and regular monitoring reports.
Q9: How many production lines do you have for general-purpose silica? A: We have 6 dedicated large-scale production lines for general-purpose precipitated silica, with an annual output of over 80,000 tons, which can stably meet bulk procurement needs of customers in Brazil and Latin America.
Q10: Do you conduct third-party testing for each batch? A: Routine indicators are tested by our internal QC laboratory for each batch. We can also arrange authoritative third-party testing (such as SGS, Intertek) according to customer requirements, with corresponding test reports provided separately.
2. In-depth Technical Parameters & Performance
Q11: How does particle size affect the application performance of silica? A: Larger particle size delivers stronger abrasion and polishing effect, suitable for whitening toothpaste and scrub products; smaller particle size provides better thickening, matting and soft focus effects, suitable for cosmetics and transparent toothpaste. Our general-purpose grade balances multiple effects and can be customized for different demands.
Q12: What is the significance of DBP oil absorption value for applications? A: DBP oil absorption value reflects the liquid adsorption capacity of silica. Higher oil absorption means better thickening and oil control performance, suitable for cosmetics and high-thickness paste; lower oil absorption is more suitable for anti-caking and flow aid scenarios in food and feed.
Q13: How does BET surface area relate to product performance? A: Higher BET surface area means more abundant pore structure and stronger adsorption performance, suitable for carrier, adsorption and thickening scenarios; lower surface area features better stability and fluidity, suitable for abrasive and anti-caking applications.
Q14: Does the product contain crystalline silica? Is there a risk of silicosis? A: Our product is 100% amorphous precipitated silica with no crystalline silica component. Conventional production and use do not pose a silicosis risk. It is recommended to wear dust masks during operation to avoid inhalation of excessive dust.
Q15: What is the pH stability range of the product in formulation systems? A: The product is chemically stable in neutral and weakly acidic/weakly alkaline systems (pH 4–10). Long-term use in strong acid or strong alkali systems is not recommended, to avoid performance degradation.
Q16: Will the product react with active ingredients in the formulation? A: Amorphous precipitated silica has high chemical inertness. Under conventional formulation conditions, it does not react with most active ingredients such as fluoride, vitamins, food additives and pharmaceutical excipients, and has excellent compatibility.
Q17: How does moisture content affect product use? A: Excessive moisture will cause powder agglomeration and poor fluidity, and may breed microorganisms. Our product controls moisture at 3.0–5.5%, which ensures good fluidity and avoids performance change caused by too low moisture and excessive static electricity.
Q18: What is the function of the loss on ignition indicator? A: Loss on ignition reflects the content of structural water and volatile impurities in silica. Our product controls loss on ignition ≤8.0%, which represents high silica purity and stable product structure under high-temperature processing.
Q19: Does the product generate static electricity? How to deal with it? A: Ultra-fine powder may generate slight static electricity during dry mixing. It can be improved by adjusting ambient humidity, adding humectants in advance, or using antistatic feeding equipment, which will not affect normal use.
Q20: What is the high temperature resistance of the product? A: Amorphous silica has excellent high temperature resistance, with its structure remaining stable below 1000℃. It can adapt to most food processing, pharmaceutical tableting and cosmetic production temperature conditions.

Q34: What is the difference between your silica and calcium carbonate abrasive for toothpaste? A: Compared with calcium carbonate, precipitated silica has more controllable abrasion, higher whiteness and better fluoride compatibility, and will not react with fluoride to reduce its efficacy. It is the preferred abrasive for medium and high-end whitening toothpaste.
Q35: Will silica affect the flavor release of toothpaste? A: The product has stable chemical properties and will not adsorb or react with essence components under normal addition ratio, with little impact on flavor release. The adsorption effect can be adjusted by changing the oil absorption value as needed.
Q36: Can this product be used in mouthwash formulations? A: Precipitated silica is mainly used in paste toothpaste. For mouthwash, it is prone to precipitation and delamination due to its powder property, so direct use in transparent mouthwash systems is not recommended.
