40-inch Wound Filter Cartridges: Filter Cartridges for Shampoo, Shower Gel, and Toothpaste Raw Materials
Product Introduction
These 40-inch wound filter cartridges are professional filtration components exclusively engineered for the purification and pretreatment of raw materials for daily chemical personal care products including shampoo, shower gel and toothpaste, manufactured with high-quality polypropylene (PP) raw materials and advanced precision spiral winding technology, in line with national food and daily chemical product safety standards as well as industry production specifications. Adopting an adhesive-free integral structural design, the cartridges eliminate secondary pollution risks from chemical additives, and the uniform winding of PP fiber yarn on a high-strength PP inner core forms a three-dimensional porous filtration structure with excellent dirt-holding capacity. Specifically developed for the physical and chemical characteristics of shampoo, shower gel and toothpaste raw materials—such as high viscosity, rich surfactants and certain particulate content—these 40-inch large-specification cartridges efficiently remove insoluble particulate impurities, suspended solids, colloidal substances, sediment and fiber residues from various liquid raw materials of the above products, improve the purity and uniformity of raw materials, prevent nozzle blockage, equipment wear and finished product quality defects in the subsequent production and filling process, and lay a solid foundation for the large-scale continuous production of high-quality daily chemical personal care products. The standard 40-inch specification is perfectly matched with the large-flow filter housings in the daily chemical industry, realizing high-efficiency filtration and stable operation in industrial production lines.
Filtration Precision
Targeting the diverse purification needs of shampoo, shower gel and toothpaste raw materials with different formulations, viscosities and particulate contents, these 40-inch wound filter cartridges provide a full range of customizable filtration precision options, with nominal filtration ratings ranging from 5 μm to 80 μm. The 5 μm, 10 μm and 20 μm high-precision models are suitable for the fine purification of high-end shampoo, shower gel stock solutions and toothpaste base slurries with strict clarity requirements, achieving the interception of fine particulates to ensure the delicate texture and uniform consistency of finished products; the 30 μm, 50 μm and 80 μm models are applied to the coarse filtration and pretreatment of raw materials with high particulate content such as plant extract crude liquids for shampoos, surfactant stock solutions and toothpaste abrasive mixed liquids, effectively removing large and medium-sized impurities and reducing the filtration load of subsequent fine purification processes. All precision specifications maintain stable interception efficiency without particle leakage under the recommended operating conditions, fully meeting the strict purification quality requirements of the daily chemical personal care product industry for shampoo, shower gel and toothpaste raw materials.
Flux
The flux performance of the 40-inch wound filter cartridges is optimized for the high-flow industrial production demand and the physical properties of shampoo, shower gel and toothpaste raw materials, with a pure water flux of 70-130 L/min·m² at 25℃ and 0.1MPa operating pressure; for the standard 40-inch cartridge, the pure water flux reaches 35-65 L/min, which is far higher than that of small-specification cartridges and fully meets the large-volume continuous filtration demand of daily chemical production lines. For normal viscosity shampoo and shower gel raw materials (≤80 mPa·s), the actual working flux is 20-45 L/min, and for toothpaste base liquids with moderate viscosity (≤150 mPa·s), the actual flux is 10-30 L/min. The flux decreases moderately with the increase of raw material viscosity and the reduction of filtration precision, and remains stable without sudden attenuation in the recommended operating pressure range, ensuring the continuous and efficient operation of large-scale production lines for shampoo, shower gel and toothpaste.
Salt Rejection Rate
As a dedicated particulate filtration cartridge for the purification of shampoo, shower gel and toothpaste raw materials, the product is designed for the interception of insoluble solid impurities, colloids and fiber residues, and does not have a desalination function, with a salt rejection rate close to 0%. It will not intercept soluble active ingredients, inorganic salts, humectants, surfactants, sweeteners and other functional components in shampoo, shower gel and toothpaste raw materials (such as glycerin, panthenol, sodium lauryl sulfate, xylitol), ensuring that the effective functional ingredients of the raw materials are not lost during the filtration process, and maximizing the retention of the efficacy, taste and use experience of finished personal care products. The abandonment of desalination design is a core structural feature that makes it highly adaptable to the purification of daily chemical raw materials with rich soluble components.
Pressure Drop
The product adopts an optimized low-resistance spiral winding structure and large effective filtration area design, with an initial pressure drop of ≤0.015MPa at 25℃ and rated pure water flux for all filtration precision specifications. This low initial pressure drop effectively reduces the energy consumption of the raw material delivery pump in large-scale daily chemical production lines, and avoids the damage of excessive pressure to the heat-sensitive active ingredients (such as plant extracts, vitamin additives) in shampoo and shower gel raw materials, as well as the agglomeration of abrasive particles in toothpaste raw materials caused by high pressure. With the progress of filtration, the pressure drop gradually increases as the filter layer intercepts more impurities; the recommended terminal operating pressure drop is ≤0.07MPa. When the pressure drop exceeds this value, the filtration flux will decrease significantly, and the cartridge needs to be cleaned or replaced in time to ensure the smooth progress of raw material purification and avoid the increase of production cost caused by low production efficiency.
Molecular Weight Cutoff (MWCO)
Combined with the filtration precision, spiral winding density and the component characteristics of shampoo, shower gel and toothpaste raw materials, the optimized Molecular Weight Cutoff (MWCO) range is 100,000 Da to 500,000 Da for these 40-inch wound filter cartridges. This MWCO range is precisely matched with the raw material components: it can effectively intercept macromolecular colloids, macromolecular particulate impurities, insoluble polymer substances, plant fiber residues and large abrasive particles in toothpaste raw materials, while allowing small and medium molecular weight active ingredients, functional additives, surfactants and water molecules to pass through smoothly. The accurate MWCO setting achieves the dual goal of efficient impurity removal and maximum retention of active ingredients, avoiding the interception of beneficial functional components and the leakage of harmful macromolecular impurities, and ensuring the purity, efficacy and use performance of shampoo, shower gel and toothpaste raw materials after filtration.
Membrane Thickness
The 40-inch wound filter cartridge features a gradient thickness filtration layer design adapted to the purification of shampoo, shower gel and toothpaste raw materials, with an effective functional filtration layer thickness of 4-9 mm, and the total outer diameter thickness of the cartridge (including high-strength PP inner core and gradient filtration layer) is a standard 28-30 mm, which is fully compatible with the installation size of large-flow standard filter housings in the daily chemical industry. The outer layer of the filtration layer is a loose spiral structure with moderate thickness for coarse interception of large particulate impurities, fiber residues and toothpaste abrasive large particles, and the inner layer is a dense spiral structure with precise thickness for fine interception of small particulates and colloids. The uniform thickness distribution of the whole filtration layer avoids local excessive pressure and filtration layer damage caused by high-flow raw material scouring, and the thickened effective filtration layer significantly improves the dirt-holding capacity and service life of the cartridge, adapting to the long-term continuous high-flow production demand of daily chemical raw material lines.
Replacement Cycle
The replacement cycle of the 40-inch wound filter cartridge is determined by the particulate content, viscosity of shampoo, shower gel and toothpaste raw materials, operating flux and system pressure drop, with a recommended normal replacement cycle of 1-3 weeks for the purification stage of these daily chemical raw materials in large-scale industrial production. For low-viscosity, low-particulate high-end shampoo and shower gel raw materials and intermittent production conditions, the replacement cycle can be appropriately extended to 2-3 weeks; for high-viscosity, high-particulate raw materials such as plant extraction crude liquids for shampoos, toothpaste abrasive mixed liquids and 24-hour continuous high-flow production lines, the replacement cycle is shortened to 1 week. In addition, when the terminal pressure drop of the cartridge exceeds 0.07MPa, the filtration flux drops by more than 30% of the initial value and cannot be recovered after physical cleaning (e.g., backwashing with purified water), or the purity and uniformity of the filtered raw materials fail to meet the production quality standard, the cartridge must be replaced immediately to ensure the stable quality of shampoo, shower gel and toothpaste raw material purification.
