Low-Emission PP Wound Filter Cartridge: Filter Cartridge for Removing Impurities from Cosmetic Formula Liquids
Product Introduction
This low-emission PP wound filter cartridge is a professional environment-friendly filtration component custom-developed for impurity removal in cosmetic formula liquids, manufactured in strict compliance with FDA 21 CFR 177.1520, EU REACH, COSMOS and low-VOC environmental protection standards for cosmetic production. Crafted from high-purity food-grade low-emission polypropylene (PP) fiber raw materials with ultra-low leachable substance content, the cartridge adopts an advanced precision spiral winding process combined with an adhesive-free hot-melt sealing structure, eliminating secondary pollution from chemical additives and minimizing the emission of volatile organic compounds (VOCs) and micro-leachable substances during use. Specifically designed for the physical and chemical characteristics of cosmetic formula liquids—including diverse formulations, rich active ingredients and trace insoluble particulate impurities—it efficiently removes suspended solids, fine particulates, colloidal substances, fiber residues and micro-scale solid impurities from various cosmetic formula liquids, without altering the formula composition, active ingredient content or physical properties of the liquids. The product features a standard industrial structural design, perfectly matched with mainstream filter housings in the cosmetic production industry, realizing efficient, stable and low-emission impurity removal for cosmetic formula liquids, and laying a solid foundation for the production of high-quality, safe and environment-friendly cosmetic finished products that meet global environmental protection and quality standards.
Filtration Precision
Targeting the graded impurity removal needs of different types of cosmetic formula liquids and different production links, this low-emission PP wound filter cartridge provides a full range of precise and customizable filtration precision options, with nominal filtration ratings ranging from 1 μm to 40 μm. The 1 μm, 3 μm and 5 μm high-precision models are suitable for the fine impurity removal of high-end cosmetic formula liquids such as essence stock solutions, hyaluronic acid solutions and plant extract serums, achieving efficient interception of submicron fine particulates and colloids to ensure the transparency and delicate texture of finished cosmetic products; the 10 μm, 20 μm and 30 μm medium-precision models are applied to the impurity removal of daily cosmetic formula liquids including toner, lotion and facial mask stock solutions, effectively removing medium-sized particulate impurities and fiber residues to balance filtration efficiency and production cost; the 40 μm coarse-precision model is used for the pre-filtration of high-viscosity cosmetic formula liquids such as cream base liquids and emulsifier mixtures with relatively high particulate content, removing large solid impurities and preventing pipeline and filter housing blockage. All precision models maintain stable and consistent interception efficiency under the recommended operating conditions, with zero particle leakage and no additional emission of harmful substances, fully meeting the stringent impurity removal and environmental protection requirements of the cosmetic production industry for formula liquids.
Flux
The flux performance of this low-emission PP wound filter cartridge is optimized for the low-viscosity to medium-viscosity characteristics of most cosmetic formula liquids and the industrial production efficiency requirements of the cosmetic industry, with a pure water flux of 55-125 L/min·m² at 25℃ and 0.1MPa operating pressure. For the standard 10-inch cartridge, the pure water flux reaches 7-17 L/min; the 20-inch cartridge is 14-34 L/min, and the 40-inch large-specification cartridge can reach 28-68 L/min, fully meeting the filtration demand of small, medium and large-scale cosmetic production lines. For normal viscosity cosmetic formula liquids (≤50 mPa·s) such as toner and essence stock solutions, the actual working flux is basically consistent with the pure water flux; for medium-viscosity formula liquids (50-100 mPa·s) such as lotion and cream base liquids, the actual flux is moderately reduced by 30%-40% under the same working conditions. The flux remains stable and predictable in the recommended operating pressure range, with no sudden attenuation, and the low-resistance winding structure design ensures that the flux does not decrease sharply with the reduction of filtration precision, perfectly matching the batch and continuous production characteristics of cosmetic formula liquids and ensuring efficient impurity removal while not affecting the production rhythm of cosmetic production lines.
Salt Rejection Rate
As a dedicated low-emission particulate filtration cartridge for impurity removal in cosmetic formula liquids, the product is designed for the interception and removal of insoluble solid impurities, colloids and fiber residues in formula liquids, and does not have a desalination or ion removal function, with a salt rejection rate close to 0%. It neither intercepts soluble active ingredients, humectants, emulsifiers, preservatives, inorganic salt additives and other functional components in aqueous cosmetic formula liquids nor affects oil-soluble active ingredients, emollients and plant essential oils in oil-based or emulsion formula liquids, ensuring that the chemical composition, formula ratio, pH value and functional properties of cosmetic formula liquids remain completely unchanged during the filtration process. The abandonment of desalination design is a core structural feature that makes the cartridge specialized for particulate impurity removal in cosmetic formula liquids, distinguishing it from water purification filter cartridges with desalination functions and ensuring the integrity of the cosmetic formula and the stability of finished product performance. At the same time, the low-emission material design avoids the introduction of additional ionic substances during filtration, further ensuring the purity of cosmetic formula liquids.
Pressure Drop
The product adopts an optimized low-resistance spiral winding structure and large-pore gradient filtration channel design, combined with the characteristics of low-emission PP fiber with good fluidity, with an initial pressure drop of ≤0.012MPa at 25℃ and rated pure water flux for all filtration precision specifications. This ultra-low initial pressure drop effectively reduces the energy consumption of the cosmetic formula liquid delivery pump in production lines, avoids the damage of excessive pressure to the heat-sensitive active ingredients (such as plant extracts, vitamin additives) in formula liquids, and prevents the agglomeration of particulate impurities in high-viscosity formula liquids caused by high pressure. With the progress of filtration, the pressure drop of the cartridge gradually increases as the three-dimensional filtration layer intercepts more impurities; the recommended terminal operating pressure drop is ≤0.07MPa for all precision models. 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 avoid excessive system pressure that may cause the re-leakage of intercepted impurities and affect the purity of formula liquids, ensuring the smooth progress of impurity removal for cosmetic formula liquids and avoiding the increase of production cost caused by low production efficiency.
Molecular Weight Cutoff (MWCO)
Combined with the filtration precision, low-emission PP fiber winding density and the component molecular characteristics of cosmetic formula liquids, the optimized Molecular Weight Cutoff (MWCO) range is 70,000 Da to 350,000 Da for this low-emission PP wound filter cartridge. This MWCO range is precisely tailored to the impurity removal needs of cosmetic formula liquids: it can effectively intercept macromolecular colloids, micro-scale fiber polymers, solid impurity aggregates, macromolecular waxy precipitates and insoluble polymer impurities (MW > 70,000 Da) in various cosmetic formula liquids, while allowing all small and medium molecular weight active ingredients, emulsifiers, humectants, preservatives and soluble additives (MW < 70,000 Da) in formula liquids to pass through smoothly and completely. The stable MWCO setting is not affected by the physical properties of different cosmetic formula liquids, achieving the dual goal of efficient impurity removal and complete retention of functional components in cosmetic formula liquids, and ensuring that the filtered formula liquids fully meet the production and quality requirements of cosmetic finished products. In addition, the low-emission material design ensures that there is no dissolution of macromolecular substances from the cartridge itself during filtration, avoiding the change of MWCO interception range caused by foreign macromolecular substances.
Membrane Thickness
This low-emission PP wound filter cartridge adopts a gradient thickness filtration layer design adapted to the impurity removal characteristics of cosmetic formula liquids, with an effective functional filtration layer thickness of 3.5-8.5 mm, and the total outer diameter thickness of the cartridge (including high-strength low-emission PP inner core and gradient filtration layer) is a standard 28-30 mm, fully compatible with the installation size of mainstream filter housings in the cosmetic production industry. The filtration layer is composed of a loose outer layer (1.5-3.5 mm) with large pore size for coarse interception of large particulate impurities and fiber residues in cosmetic formula liquids, a medium-density middle layer (1-2 mm) for interception of medium-sized particulates and colloids, and a dense inner layer (1-3 mm) for fine interception of small fine particulates, forming a multi-layer gradient thickness winding structure through hot-melt bonding. This structural design not only maximizes the dirt-holding capacity and filtration efficiency of the cartridge but also ensures excellent mechanical stability and low flow resistance; the uniform thickness distribution of the whole filtration layer avoids local excessive pressure and filtration layer damage caused by the scouring of formula liquids, and the low-emission PP fiber material with high structural stability adapts to the long-term continuous filtration demand of cosmetic formula liquid production lines.
Replacement Cycle
The replacement cycle of this low-emission PP wound filter cartridge is determined by the impurity content, viscosity of cosmetic formula liquids, daily filtration volume and system pressure drop, with a recommended normal replacement cycle of 2-5 weeks for the impurity removal stage of cosmetic formula liquids in cosmetic production enterprises. For low-viscosity, low-impurity high-end cosmetic formula liquids (such as essence stock solutions, hyaluronic acid solutions) and intermittent production conditions, the replacement cycle can be appropriately extended to 4-5 weeks (40 μm/30 μm models) and 3-4 weeks (1 μm/5 μm models); for medium-viscosity, relatively high-impurity formula liquids (such as cream base liquids, plant extract crude liquids) and 24-hour continuous large-flow production lines, the replacement cycle is shortened to 2-3 weeks for all precision models. In addition, the cartridge must be replaced immediately if any of the following conditions occur: the terminal pressure drop exceeds 0.07MPa, the filtration flux drops by more than 30% of the initial value and cannot be recovered after physical cleaning (such as backwashing with purified water), the filtered formula liquids appear particulate sedimentation or turbidity, or the cartridge is used for more than 5 weeks (even if the pressure drop and flux are normal), to avoid microbial breeding on the filtration layer and the increase of leachable substance emission caused by long-term use, ensuring the purity, safety and low-emission performance of cosmetic formula liquids.
