I. Product Overview This product is a nano-sized cosmetic-grade exfoliating silica dioxide independently developed by Zhongqi Guangdong Silicon Material Co., Ltd. It is a high-performance cosmetic raw material custom-developed to address the core pain points in the cosmetics industry: "rough and irritating exfoliating particles, uneven skin feel, and insufficient stability". Relying on nano-sized precise particle size control and sophisticated process optimization, the product not only solves the problems of strong irritation and uneven exfoliation of traditional exfoliating raw materials, but also has excellent skin feel adjustment performance and safety guarantees. It is widely used in cosmetics fields such as facial cleansers, body care products, and color cosmetics, and is exported to international cosmetics markets such as Southeast Asia, Europe, America, Japan, and South Korea. II. Core Product Advantages 1. Gentle Exfoliation and Skin Feel Stability The product adopts precise particle size classification technology, with regular spherical or quasi-spherical particle morphology, which feels delicate and smooth. It can achieve gentle and efficient exfoliation effect, avoiding scratches and excessive irritation to the skin caused by traditional angular exfoliating particles. At the same time, it has excellent temperature resistance and chemical stability. It does not change its shape or react with other ingredients during cosmetics production (such as emulsification, high-temperature homogenization) and storage, ensuring that the skin feel of the product is always stable and consistent, suitable for different skin types. 2. High Purity and Cosmetic-Grade Safety Guarantee Strictly adhering to cosmetic-grade raw material standards, the product has extremely high purity, and the content of heavy metals (lead, mercury, arsenic, etc.) is much lower than the industry limit. It fully complies with the national standard GB/T 30646-2014 "Silica Dioxide for Cosmetics" and the US FDA 21 CFR cosmetic raw material safety specifications. The entire production process is completed in a cosmetic GMP-certified workshop, and a full-chain safety control system has been established from quartz sand raw material screening to finished product delivery. It has passed multiple skin irritation tests to ensure safe use in various cosmetic formulations. 3. Excellent Dispersibility and Formula Compatibility Relying on the unique surface modification technology of nano-sized particles, the product has excellent dispersibility in aqueous, oil-based and emulsified systems. It does not agglomerate or settle, and can be evenly dispersed in various cosmetic matrices. It can significantly improve the delicacy and smoothness of the product's skin feel, and at the same time improve the fluidity of creams or powders, enhancing production and filling efficiency. It is suitable for various product formulations such as facial cleansers, scrubs, exfoliating creams, and face powders. 4. Precise Particle Size Customization Capability It supports customized services in the particle size range of 1-30μm, and accurately matches the particle size according to the exfoliation needs of different cosmetic categories: for example, facial cleanser products are suitable for 1-5μm ultra-fine particle size to achieve gentle exfoliation, body scrub products are suitable for 10-20μm particle size to enhance cleansing power, and color cosmetic powders are suitable for 5-10μm particle size to improve skin feel. It provides personalized solutions for customers' specific formulation processes to meet diverse application scenarios. 5. Full-Cycle Technical Service Guarantee It provides full-cycle technical support covering pre-sales, in-sales and after-sales: pre-sales, multiple particle size samples can be provided for customers to conduct formulation testing and skin feel verification; in-sales, technical engineers are arranged to assist customers in optimizing formulation ratios and solving process problems such as dispersion and stability; after-sales, a rapid response mechanism is established to promptly solve various technical problems during product application and ensure the full play of raw material performance. III. Production Strength Guarantee Zhongqi Guangdong Silicon Material Co., Ltd. has been deeply engaged in the silicon material field for more than 20 years. As a national high-tech enterprise and a provincial-level "Specialized, Refined, Characteristic and Innovative" enterprise, it provides solid support for the quality of cosmetic-grade exfoliating silica dioxide. The company has 23 patented technologies related to cosmetic raw materials, and has built a cosmetic-grade GMP standardized production base. Equipped with advanced testing equipment such as laser particle size analyzers, atomic absorption spectrometers, and skin irritation testing equipment, it has established 32 full-process inspection procedures covering key links such as raw material purity testing, particle size distribution testing, and safety evaluation. It has obtained ISO 22716 Cosmetic Good Manufacturing Practice certification, realizing full-chain standardized control from R&D, production to quality inspection. IV. Packaging and Transportation Specifications 1. Standard Packaging Specifications Adopting a clean packaging design dedicated to cosmetic raw materials, it provides 5kg, 10kg, and 20kg aluminum foil composite bag packaging options, equipped with a sealed valve design to meet the different order needs of small-batch R&D and large-batch production. 2. Clean and Waterproof Protection To ensure the cleanliness and stability of raw materials, a dual protection scheme is adopted: Scheme 1 is inner food-grade PE bag + outer aluminum foil composite bag; Scheme 2 is vacuum aluminum foil bag + corrugated carton reinforcement. It effectively isolates moisture, impurities and light, preventing raw materials from absorbing moisture, agglomerating, or becoming contaminated and deteriorated. 3. Storage and Transportation Requirements - Storage conditions: It should be stored in a cool, dry, well-ventilated and clean warehouse, avoiding direct sunlight, high temperature and humid environment, and kept away from flammable, explosive and corrosive substances; - Shelf life: Under standard storage conditions, the shelf life is 24 months; - Transportation attribute: The product is a non-hazardous chemical, which complies with international air, sea and land transportation dangerous goods regulations. It supports global door-to-door delivery to ensure safe receipt by domestic and foreign customers. 37. Standard Label Management Each batch of product packaging is strictly marked with legal information such as cosmetic raw material attributes, particle size specifications, production date, shelf life, and production license number, which complies with China's "Cosmetic Supervision and Administration Regulations" and international regulatory requirements such as EU CE and US FDA. Multilingual labels can be customized according to customer needs to adapt to the regulatory specifications of different countries and regions. V. Applicable Application Fields The product is mainly suitable for exfoliating and skin feel adjusting products in the cosmetics field, including: facial care products (such as amino acid exfoliating facial cleansers, gentle exfoliating serums, skin-rejuvenating essence creams); body care products (such as sea salt scrubs, moisturizing exfoliating body lotions, foot scrub products); color cosmetics (such as oil-controlling matte face powders, smooth loose powders, exfoliating texture lipsticks); at the same time, it can be extended to subdivided fields such as children's cosmetics (ultra-fine particle size version), men's skin care (medium exfoliation version), and sensitive skin-specific care products (low-irritation version). It has been widely recognized by well-known domestic and foreign cosmetics enterprises for its gentleness and stability. VI.
