Revolutionizing Hair Dye & Shampoo Production with INOXPA Reactors
Introduction
A European cosmetics company, globally recognized for more than two decades for its innovation and premium hair dye and hair care solutions, soon faced a major challenge as international demand grew rapidly. They had to increase production capacity while maintaining precise control over texture, viscosity, and batch consistency. To achieve this without affecting product quality, they partnered with INOXPA and chose reactor systems built on the trusted VISCOMIX and MCR platforms.
In addition to expanding output, the company also aimed to enhance downstream integration with supporting equipment such as bottle filling machines, automatic liquid filling machines, and automated conveyor systems to streamline the full production line from mixing to final packaging.
The core project goals were:
- Achieve a major increase in production capacity for both hair dye and shampoo, without compromising consistency.
- Ensure highly accurate control of mixing, temperature, and vacuum settings to guarantee uniform results across every batch.
- Install equipment that is easy to sterilize, hygienic, and fully meets international cosmetic manufacturing standards.
- Integrate with the customer's ERP system for recipe automation and traceability using next-gen smart factory technology.
- Enable seamless material transfer.
Hair Dye Reactor: VISCOMIX 600L System
System Overview
- Six 600 L VISCOMIX reactors mounted on load cells for dosing precision.
- Thermal control via direct steam heating and water cooling.
- A full vacuum circuit with a top hydraulic lifter and split heating jacket, optimized even for partial batch loads.
- Designed to handle hair dye creams with a static viscosity of approx. 2000 Cp.
Mixing & Dispensing
Delivering superior dispersion control and high uniformity in color and texture, this configuration of the VISCOMIX reactor features a dual-level external recirculation system, a high-shear bottom mixer, and an elliptical anchor propeller. A notable advantage is its ability to feed products directly to filling equipment, thereby eliminating the need for intermediate transfer pumps.
This direct discharge capability also creates an ideal setup for automated conveyor systems, ensuring continuous, uninterrupted production flow from mixing to packaging which is critical for handling high-demand product lines efficiently.
Automation & Control
- Integrated HMI touchscreen mounted on the reactor, connected to the facility’s central control system.
- Barcode-based identification of solid ingredients and load cell–driven precision dosing for liquids ensure accurate formulation, governed through an intelligent recipe execution system.
- Automated process validation and complete material traceability across every batch are achieved through seamless integration with the company’s ERP infrastructure.
Benefits Delivered
- Achieved faster production rates with excellent batch repeatability and consistent color output.
- Adaptable to different viscosities and complex formulations, offering strong process flexibility.
- Fully meets FDA and GMP hygiene requirements.
- Pharmaceutical-grade cleanliness is achieved through support for steam or superheated water sterilization.
- Engineered for seamless integration into a fully automated production line, operating efficiently with downstream automatic liquid filling machines, bottle filling machines, and automated conveyor systems.
Shampoo Manufacturing: 3000L MCR Reactor
System Overview
- A single 3,000 L MCR reactor engineered to process shampoos with viscosities reaching up to 5,000 Cp.
- Equipped with a dual-action mixing system incorporating counter-rotating agitators with helical blades and scrapers, supported by a centrally positioned blade assembly.
- Designed to achieve maximum batch capacity while preserving absolute formulation uniformity throughout every cycle.
Loading & Heating
- A vacuum-assisted bottom inlet with a 4-valve manifold enables smooth and controlled incorporation of both powders and liquids.
- Jacketed system for efficient steam heating and chilled water cooling.
- Consistent temperature control prevents ingredient degradation which is critical for sensitive active components.
Cleaning & Hygiene Features
- Three rotating spray balls on the reactor top for automated cleaning.
- Removable internal spray balls to eliminate dead-zone contamination.
- Dual-level recirculation from the bottom, specially optimized for high-viscosity cosmetic products.
This configuration ensures perfect compatibility with bottle filling machines and automatic liquid filling machines, as the output viscosity and homogeneity are precisely controlled for filling efficiency. Furthermore, the compatibility with automated conveyor systems ensures optimal transition from processing to filling to packing.
Automation & Controls
- Siemens S7-1500 PLC paired with a 12-inch HMI Comfort touchscreen enables intuitive local operation.
- Onboard USB-based data logging enables secure batch documentation and complete production traceability from start to finish.
- Integrated ERP connectivity supports fully autonomous, recipe-driven execution with minimal manual intervention.
Benefits Delivered
- Highly precise control over thermal dynamics and mixing integrity throughout each batch.
- Minimized downtime thanks to rapid batch transitions and operator-friendly cleaning functionality.
- Can adapt to various batch sizes and viscosities effortlessly.
- Fully compatible with integrated bottle filling machines, automatic liquid filling machines, and automated conveyor systems to support end-to-end production automation.
