Food Grade PP Wound Filter Cartridges: Filter Cartridges for Cosmetic and Skincare Product Raw Materials
Product Introduction
These food grade PP wound filter cartridges are professional filtration components custom-engineered for the pretreatment and purification of cosmetic and skincare product raw materials, manufactured with high-purity food-grade polypropylene (PP) raw materials in line with FDA 21 CFR 177.1520, EU REACH and cosmetic GMP production standards. Adopting a precision spiral winding process with an adhesive-free integral structure, the cartridges eliminate the risk of secondary pollution from chemical additives, and the uniform winding of PP fiber yarn on a corrosion-resistant food-grade PP inner core forms a three-dimensional porous filtration structure. Specifically designed for the physical and chemical characteristics of cosmetic raw materials, they efficiently remove insoluble particulate impurities, suspended solids, colloidal substances, sediment and fine fiber impurities from various liquid raw materials for cosmetics and skincare products, improve the purity and clarity of raw materials, prevent pipeline blockage and equipment wear in the subsequent production process, and lay a solid foundation for the preparation of high-quality cosmetic and skincare finished products. The product is available in mainstream industrial specifications, perfectly matching the standard filter housings in the cosmetic production industry, and realizing stable and continuous operation in large-scale production lines.
Filtration Precision
Aiming at the diverse purification needs of cosmetic and skincare raw materials with different formulations and application scenarios, these food grade PP wound filter cartridges provide a full range of precise filtration precision options, with nominal filtration ratings ranging from 1 μm to 50 μm. The 1 μm, 3 μm and 5 μm high-precision models are suitable for the fine purification of high-end cosmetic raw materials such as essence stock solution, hyaluronic acid solution and plant extract stock solution, achieving the interception of submicron fine particulates to ensure the transparency and delicate texture of finished products; the 10 μm, 20 μm and 50 μm models are applied to the coarse filtration and pretreatment of raw materials with high particulate content such as cosmetic lotion base material, surfactant solution and plant extraction crude liquid, 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, meeting the strict purification quality requirements of the cosmetic and skincare industry.
Flux
The flux performance of the food grade PP wound filter cartridges is optimized for the viscosity, density and industrial production efficiency requirements of cosmetic liquid raw materials, with a pure water flux of 60-120 L/min·m² at 25℃ and 0.1MPa operating pressure. For the standard 10-inch cartridge, the pure water flux reaches 8-15 L/min, and the 20-inch cartridge is 16-30 L/min; for normal viscosity cosmetic raw materials (≤30 mPa·s) such as toner base liquid and essence stock solution, the actual working flux is 3-10 L/min for 10-inch and 6-20 L/min for 20-inch. The flux decreases moderately and linearly 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. The large effective filtration area design fully meets the large-volume continuous filtration demand of cosmetic and skincare raw material production lines.
Salt Rejection Rate
As a dedicated particulate filtration cartridge for cosmetic and skincare raw material purification, the product is designed for the interception of insoluble solid impurities and colloids, and does not have a desalination function, with a salt rejection rate close to 0%. It will not intercept soluble active ingredients, inorganic salts, small molecular weight humectants, emollients and other functional components in cosmetic raw materials (such as glycerin, propylene glycol, amino acid moisturizers), ensuring that the effective functional ingredients of the raw materials are not lost during the filtration process, and maximizing the retention of the efficacy and quality of cosmetic and skincare finished products. The abandonment of desalination design is a core structural feature that makes it suitable for the purification of cosmetic raw materials with diverse soluble components.
Pressure Drop
The product adopts an optimized low-resistance spiral winding structure design, with an initial pressure drop of ≤0.012MPa 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 the cosmetic production line, and avoids the damage of excessive pressure to the heat-sensitive and easily degraded active ingredients in cosmetic raw materials (such as plant extracts, vitamin components). With the progress of filtration, the pressure drop gradually increases as the filter layer intercepts more impurities; the recommended terminal operating pressure drop is ≤0.065MPa. 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 and spiral winding density of the cartridge, the optimized Molecular Weight Cutoff (MWCO) range is 80,000 Da to 400,000 Da for these food grade PP wound filter cartridges. This MWCO range is precisely matched with the component characteristics of cosmetic and skincare raw materials: it can effectively intercept macromolecular colloids, macromolecular particulate impurities, insoluble polymer substances and plant fiber residues in the raw materials, while allowing small and medium molecular weight active ingredients, functional additives 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 and efficacy of cosmetic raw materials after filtration.
Membrane Thickness
The food grade PP wound filter cartridge features a gradient thickness filtration layer design adapted to cosmetic raw material purification, with an effective functional filtration layer thickness of 3.5-7.5 mm, and the total outer diameter thickness of the cartridge (including food-grade PP inner core and gradient filtration layer) is a standard 28-30 mm, which is fully compatible with the installation size of standard filter housings in the cosmetic production industry. The outer layer of the filtration layer is a loose spiral structure with moderate thickness for coarse interception of large particulate impurities and fiber residues, 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, and the thickened effective filtration layer significantly improves the dirt-holding capacity and service life of the cartridge, adapting to the long-term continuous production demand of cosmetic and skincare raw material lines.
Replacement Cycle
The replacement cycle of the food grade PP wound filter cartridge is determined by the particulate content, viscosity of cosmetic raw materials, operating flux and system pressure drop, with a recommended normal replacement cycle of 2-4 weeks for the purification stage of cosmetic and skincare product raw materials. For low-viscosity, low-particulate high-end cosmetic raw materials (such as essence stock solution, hyaluronic acid solution) and intermittent production conditions, the replacement cycle can be appropriately extended to 3-4 weeks; for high-viscosity, high-particulate raw materials (such as plant extraction crude liquid, cosmetic cream base material) and 24-hour continuous industrial production lines, the replacement cycle is shortened to 2 weeks. In addition, when the terminal pressure drop of the cartridge exceeds 0.065MPa, 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 clarity of the filtered raw materials fail to meet the production quality standard, the cartridge must be replaced immediately to ensure the stable quality of cosmetic and skincare raw material purification.
