Explore our premier, CE-certified production systems designed to meet rigorous cosmetic, pharmaceutical, and food-grade cleanroom environments.
The global consumer demands for high-quality cosmetics, personal hygiene products, and dermatological creams have experienced rapid growth. In a post-pandemic economy, the commercial landscape for liquid soaps, therapeutic shampoos, and emulsion-based skincare creams is moving toward highly efficient production paradigms. Sourcing reliable manufacturing hardware is no longer just about buying a stainless steel vessel; it requires finding machinery configured to optimize yield, control particle size distributions, reduce process waste, and maintain strict sanitary criteria.
Today, the chemical mixing and cosmetic manufacturing industries require compliance with CE Certification and GMP (Good Manufacturing Practice) standards. Consumer safety and product quality depend entirely on the equipment's capacity to maintain a stable environment under varying shear forces, temperature fluctuations, and vacuum seals. Standard sanitary mixers are being replaced by highly automated, multi-functional vacuum homogenizing and emulsifying lines that can process complex cosmetic formulations from start to finish.
Furthermore, local regulatory shifts across the European Union, North America, and Eastern markets mandate strict traceability and process reproducibility. Systems must deliver precise control over batch integrity, which requires robust engineering designs, certified sanitary components (such as SUS316L structures), and modular control units that prevent batch contamination. These requirements make it essential for companies to select the right liquid soap and shampoo machinery partners.
Achieving a perfect suspension of immiscible liquids requires precise mechanical control over shear forces, fluid dynamics, and temperature controls within the mixing chamber.
Our mixers feature precision-engineered rotor-stator homogenizers that run at speeds up to 3000–3600 RPM. High kinetic energy forces raw materials through narrow gaps, reducing droplet sizes down to the sub-micron range (< 2μm) to ensure stable emulsions for premium cosmetic creams.
Processing under vacuum (-0.09Mpa) prevents air entrainment during fast mixing. This design protects active ingredients from oxidation and prevents bubble formation, extending shelf life and ensuring a smooth, premium finish for shampoos, liquid detergents, and pastes.
Dual or triple-action agitating systems combine a center impeller with Teflon scrapers that continually clear product from the inner walls. This prevents product scorching and cold spots while facilitating heat transfer throughout the batch.
Founded in 1992, SINAEKATO has grown to become a global leader in designing, fabricating, and commissioning process equipment for the cosmetic and pharmaceutical sectors.
SINAEKATO's machinery systems are developed with a primary commitment: "LET THE WORLD KNOW MADE IN CHINA" by delivering high-performance machinery, engineering, and support services. Every vacuum emulsifier, liquid-washing mixer, RO water treatment facility, and filling machine we build represents decades of R&D and application experience.
To ensure high performance and reliability, 80% of our key component parts are sourced from leading global suppliers (including Siemens PLCs, ABB Motors, Schneider Electrical components, Omron controls, and NSK Bearings). This global component strategy, combined with our advanced manufacturing and testing processes, ensures our equipment operates reliably in demanding production environments.
Different cosmetic formulations demand specialized process designs. We engineer systems tailored to specific product requirements:
These formulations require thorough dissolution of surfactants (such as AES/SLES) without air entrapment. Our liquid washing systems utilize bottom-entry homogenizers, high-speed dispersers, and recirculation loops to accelerate dissolution, reduce cycle times, and prevent foaming.
Viscosity and temperature control are critical for shampoos. Dynamic agitation ensures uniform distribution of conditioning polymers and salts, while automated temperature tracking controls viscosity during cooling to prevent separation or sedimentation.
Premium lotions require micro-droplet dispersion to maintain emulsion stability. Our vacuum emulsifiers create high shear rates that distribute oil and water phases evenly. Precise cooling systems manage the phase transitions required to achieve the desired cosmetic texture.
Sourcing your process systems from SINAEKATO’s advanced production facilities in China offers significant manufacturing advantages without compromising on quality or compliance. Located in Gaoyou City, our 10,000-square-meter facility utilizes automated welding systems, high-precision lathe machinery, and advanced non-destructive testing tools to manufacture process vessels that meet international standards.
Our localized supply chain in Jiangsu and Guangdong allows us to source raw materials, specialized structural steels (SUS304 and SUS316L), and structural components efficiently. This cluster effect reduces fabrication lead times and keeps production costs competitive. We pass these cost efficiencies directly to our customers, offering premium-grade equipment at a lower capital expenditure than European counterparts.
Additionally, our production teams handle design, structural engineering, welding, polishing, electronic controls, and testing in-house. Before dispatching any vacuum emulsifying mixer or liquid wash system, we run comprehensive testing protocols, including dye-penetrant testing, polishing inspections, and operational runs. This ensures your system is ready for installation upon delivery.
When selecting processing systems for liquid soaps, cosmetic creams, and shampoos, evaluate the following parameters to ensure optimal Total Cost of Ownership (TCO):
Ensure the supplier provides genuine CE conformity declarations covering the Machinery Directive (2006/42/EC), Low Voltage Directive (2014/35/EU), and EMC compatibility to protect your operators and maintain compliance.
Validate that all product-contact surfaces use SUS316L stainless steel, polished to Ra < 0.4μm, with certificate verification to prevent corrosion from saline surfactant solutions.
Select a partner that can scale your laboratory formulations (such as 5L or 10L test units) up to production sizes (up to 3500L or 5000L systems) while keeping the same shear rates and thermal profiles.

CE Certification indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA). For liquid mixers and homogenizers, it ensures compliance with the Machinery Directive (2006/42/EC), Low Voltage Directive (2014/35/EU), and Electromagnetic Compatibility (EMC) Directive. This certification verifies that the equipment's mechanical, electrical, and control systems meet global safety standards.
Top-entry homogenizers are suspended from the top vessel lid, making them suitable for high-viscosity emulsions like heavy creams. They work alongside scraper agitators to cycle thick materials through the high-shear zone. Bottom-entry homogenizers are installed at the base of the tank. This position enables them to handle low-to-medium viscosity liquids (such as liquid detergents and shampoos) and process small batch volumes without requiring the vessel to be fully filled.
SUS316L stainless steel contains molybdenum, which significantly improves resistance to pitting and crevice corrosion in chloride-rich environments. Shampoos and liquid detergents often contain active salts, surfactants, and acidic compounds that can corrode SUS304 over time. Additionally, SUS316L provides a highly sanitary contact surface that prevents bacterial growth and supports CIP (Clean-In-Place) procedures.
High-shear mixing naturally introduces air bubbles into the product, which can oxidize active ingredients and destabilize the emulsion. By applying a vacuum (usually down to -0.09 Mpa) within the mixing chamber, air bubbles are drawn out of the product. This creates a dense, smooth cream, extends the product's shelf life, and ensures precise density control for automated filling lines.
Teflon scraper blades continuously clear the product layer from the heated or cooled walls of the mixing vessel. This constant scraping prevents product burning or build-up on the heat transfer surfaces. It ensures uniform temperature distribution throughout the batch, reduces energy consumption, and accelerates cycle times.
We provide comprehensive installation support, including detailed layout drawings, user manuals, and wiring schematics. Our engineers travel globally to assist with equipment assembly, commissioning, and staff training.
