Product Overview This product is a nano-sized cosmetic-grade silica independently developed by Zhongqi Guangdong Silicon Material Co., Ltd. It is a high-performance additive specifically customized for the foot care product industry to address the core pain points: "insufficient moisture absorption and anti-slip properties, rough skin feel, and poor stability". Leveraging nano-scale particle size combined with precise process control, the product not only efficiently absorbs foot moisture and enhances anti-slip performance but also features mild skin-friendliness and excellent stability. Passing strict safety tests, it is widely used in foot care products such as foot powder, foot bath salts, and foot care creams, and exported to international markets including Southeast Asia, Europe, and the Americas. II. Core Product Advantages 1. Superb Moisture Absorption and Anti-Slip Performance With a well-developed porous structure and large specific surface area, the product's moisture absorption rate is over 50% higher than that of ordinary silica. It can quickly absorb foot sweat and moisture to keep feet dry. Meanwhile, its unique particle morphology forms a uniform friction interface, effectively improving the anti-slip effect of foot powder on the skin surface and avoiding slipping risks caused by dampness. Even after absorbing moisture, it remains loose without caking or stickiness. 2. Mild Skin-Friendliness and Safety Guarantee Strictly complying with cosmetic-grade material standards, the product uses high-purity raw materials processed through special impurity removal technology, with heavy metal content far below industry standards. It is odorless, non-irritating, and has passed skin irritation and sensitization tests. Fully meeting the national standard GB/T 29665-2013 "Silica for Cosmetics" and the EU ECOCERT natural and organic certification standard, the entire production process is completed in a GMPC-certified workshop. A full-chain safety control system is established from raw material selection to finished product delivery to ensure safe application in various foot care scenarios. 3. Excellent Stability and Compatibility Benefiting from the uniform distribution of nano-sized particles, the product exhibits excellent compatibility with other ingredients in foot powder (such as talc, menthol, antibacterial agents, etc.) without delamination or precipitation. It also possesses outstanding high-temperature resistance and acid-alkali resistance, maintaining stable performance within a wide temperature range and pH value of 4-8, ensuring consistent efficacy of foot powder products during their shelf life. 4. Flexible Customization Capability We offer particle size customization services ranging from 2-50μm. According to the characteristics of different foot powder products (e.g., refreshing foot powder, nourishing foot powder, sports-specific foot powder), we can adjust particle size and porous structure. For customers' special needs, surface modification services are also available to further enhance dispersion, lipophilicity, or hydrophilicity, meeting diverse formulation requirements. 5. Full-Cycle Technical Service Support Comprehensive pre-sales and after-sales technical support are provided. Pre-sales, customized samples can be supplied for customers' testing and verification, along with detailed application test reports. After-sales, a professional technical team is available to solve various technical issues such as product compatibility, production process optimization, and efficacy improvement, ensuring the full play of product performance. III. Production Strength Guarantee With over 20 years of deep involvement in the silicon material industry, Zhongqi Guangdong Silicon Material Co., Ltd. serves as a national high-tech enterprise and a provincial-level "specialized, refined, unique, and innovative" enterprise, providing solid quality assurance for foot powder silica products. The company holds 17 patents in silicon material R&D and operates a GMPC-certified cosmetic-grade production base. Equipped with advanced testing equipment including atomic fluorescence spectrometers and laser particle size analyzers, it has established 26 full-process inspection procedures covering raw materials, semi-finished products, and finished products. Additionally, it has obtained ISO22716 Cosmetic Good Manufacturing Practices certification, realizing full-chain standardized control from R&D, production to quality inspection. IV. Packaging and Transportation Specifications 1. Standard Packaging Specifications Adopting cosmetic-grade standardized packaging design, we offer 10kg, 15kg, and 20kg sealed composite plastic bag options. Meanwhile, 50kg large packaging and 1kg sample packaging are available according to customer order quantities, meeting different purchasing and trial needs. 2. Professional Moisture-Proof and Fresh-Keeping Design To protect the product's moisture absorption performance during transportation and storage, a dual moisture-proof and fresh-keeping solution is adopted: Solution 1: Aluminum foil composite bag + vacuum packaging + outer carton; Solution 2: PE inner bag + sealed valve woven bag. Both solutions provide comprehensive protection against moisture and impurity intrusion, preventing product caking and performance degradation due to moisture absorption. 3. Storage and Transportation Requirements Storage conditions: Should be stored in a cool, dry, and well-ventilated warehouse, avoiding direct sunlight and proximity to water sources. Mixing with corrosive substances is strictly prohibited; Shelf life: 24 months under standard storage conditions; Transportation attribute: The product is a non-hazardous chemical, supporting multiple transportation methods such as sea freight, land freight, and air freight. It can be safely delivered to designated locations of domestic and foreign customers. Violent collisions and rain exposure should be avoided during transportation. 18. Standard Labeling Each batch of product packaging is strictly marked with legal information including cosmetic additive attribute, ingredient content, production date, shelf life, and production license number. Custom label designs are available to meet the regulatory requirements of different countries and regions for cosmetic products. V. Applicable Application Fields The product is mainly suitable for the foot care product industry, focusing on foot powder (e.g., refreshing moisture-absorbing foot powder, sports anti-slip foot powder, bacteriostatic deodorant foot powder), foot bath products (e.g., foot bath salts, foot bath packs), and foot care creams. Additionally, it can be extended to other cosmetic fields requiring moisture absorption, anti-slip, or thickening functions, such as shoe dehumidifiers and hand dry powder. With its excellent comprehensive performance and safety guarantee, it has gained recognition and long-term cooperation from numerous domestic and foreign cosmetic enterprises. VI. Conclusion Zhongqi's foot powder silica is positioned at the core of "high-efficiency moisture absorption, mild safety, and customized adaptation". Relying on strong R&D capabilities, strict quality control, and a comprehensive service system, we provide one-stop additive solutions for foot care product enterprises. Committed to promoting the upgrading of the foot care industry with high-quality silicon materials, we warmly welcome inquiries and cooperation from domestic and foreign customers.
