10-inch Daily Chemical Filter Cartridge: Fine Filtration Filter Cartridge for Perfume and Cologne Concentrate

Product Introduction

This 10-inch daily chemical filter cartridge is a professional fine filtration component custom-developed for the purification of perfume and cologne concentrates, manufactured in strict accordance with daily chemical industry safety standards, FDA 21 CFR 177.1520 and EU REACH regulations for fragrance raw materials. Crafted from high-purity food-grade polypropylene (PP) and hydrophobic modified polymer materials, the cartridge adopts an advanced precision winding process with an adhesive-free hot-melt bonding structure, eliminating any risk of secondary pollution from chemical additives, binders or leachable substances. Specifically designed for the unique physical and chemical characteristics of perfume and cologne concentrates—including high volatility, rich aromatic components, and trace insoluble particulate impurities—it efficiently removes fine particulates, colloidal substances, fiber residues and micro-scale solid impurities from fragrance concentrates, without altering the aromatic composition, concentration or sensory properties of the concentrates. The standard 10-inch specification is perfectly matched with small and medium-scale filter housings in the fragrance production industry, realizing compact, efficient and stable fine filtration for perfume and cologne concentrate preparation, and laying a solid foundation for the production of clear, transparent and high-quality perfume and cologne finished products with a pure fragrance profile.

Filtration Precision

Targeting the strict clarity and purity requirements of perfume and cologne concentrates, this 10-inch daily chemical filter cartridge offers ultra-fine and dedicated filtration precision options with nominal filtration ratings ranging from 0.5 μm to 5 μm, the core specifications for fragrance concentrate fine filtration. The 0.5 μm and 1 μm ultra-high precision models are the premium choice for high-end pure perfume and cologne concentrates, achieving complete interception of submicron fine particulates and colloidal impurities to ensure the absolute transparency of the concentrate and avoid sedimentation or turbidity in finished fragrance products; the 3 μm and 5 μm fine precision models are suitable for the fine filtration of scented cologne concentrates and fragrance stock solutions with complex formulations, effectively removing micro-scale fiber residues and solid impurities while balancing filtration efficiency and aromatic component retention. All precision models maintain consistent and stable interception efficiency under the recommended operating conditions, with zero particle leakage, and do not cause any adsorption or loss of aromatic small molecules, fully meeting the stringent fine filtration quality requirements of the perfume and cologne production industry for concentrates.

Flux

The flux performance of this 10-inch daily chemical filter cartridge is optimized for the low-flow, high-purity fine filtration characteristics of perfume and cologne concentrates and the production process of small and medium-scale fragrance enterprises, with a pure water flux of 30-60 L/min·m² at 25℃ and 0.1MPa operating pressure. For the standard 10-inch cartridge, the pure water flux reaches 4-8 L/min for the 0.5/1 μm models and 6-10 L/min for the 3/5 μm models. For perfume and cologne concentrates (with a viscosity of ≤20 mPa·s, the mainstream viscosity range in production), the actual working flux is 2-4 L/min for the ultra-high precision models and 4-6 L/min for the fine precision models. The flux remains stable and predictable in the recommended low-pressure operating range, with no sudden attenuation, and the flux design is perfectly matched with the small-batch, high-precision production characteristics of perfume and cologne concentrates, ensuring efficient fine filtration while avoiding excessive shearing force that may damage the aromatic components of the concentrates.

Salt Rejection Rate

As a dedicated fine filtration cartridge for perfume and cologne concentrates, the product is designed for the interception of insoluble fine particulates, colloids and micro-scale solid impurities, and does not have a desalination or ion removal function, with a salt rejection rate close to 0%. It neither intercepts the soluble small molecular weight aromatic components, essential oil monomers and fragrance fixatives in perfume and cologne concentrates (such as terpenes, esters, alcohols) nor affects the soluble inorganic salt trace additives in cologne concentrates, ensuring that the chemical composition, aromatic profile and concentration of the concentrates remain completely unchanged during the filtration process. The abandonment of desalination design is a core structural feature that makes the cartridge specialized for particulate removal in fragrance concentrates, distinguishing it from water purification filter cartridges with desalination functions and ensuring the integrity of the fragrance concentrate’s formula and sensory properties.

Pressure Drop

The product features an optimized low-resistance precision winding structure and hydrophobic modified filtration surface design, with an initial pressure drop of ≤0.008MPa at 25℃ and rated pure water flux for all filtration precision specifications (0.5/1/3/5 μm), which is far lower than conventional fine filtration cartridges. This ultra-low initial pressure drop effectively reduces the working pressure of the concentrate delivery pump in fragrance production lines, avoids the volatilization of aromatic components caused by high-pressure shearing and temperature rise, and prevents the damage of high pressure to the delicate formula of perfume concentrates. With the progress of fine filtration, the pressure drop gradually increases as the filtration layer intercepts more fine particulates and colloids; the recommended terminal operating pressure drop is ≤0.05MPa. When the pressure drop exceeds this value, the filtration flux will decrease significantly, and the cartridge needs to be replaced in time to avoid excessive system pressure that may cause the re-dissolution of intercepted impurities or the volatilization of key aromatic components, which is critical for maintaining the purity and fragrance integrity of perfume and cologne concentrates.

Molecular Weight Cutoff (MWCO)

Combined with the ultra-fine filtration precision, hydrophobic modified membrane pore size distribution and the molecular characteristics of perfume and cologne concentrate components, the optimized Molecular Weight Cutoff (MWCO) range is 5,000 Da to 30,000 Da for this 10-inch daily chemical filter cartridge, which is precisely tailored to the needs of fragrance concentrate fine filtration. This narrow and low MWCO range can effectively intercept macromolecular colloids, micro-scale fiber polymers, solid impurity aggregates and macromolecular waxy substances (MW > 5,000 Da) in fragrance concentrates, while allowing all small molecular weight aromatic components, essential oil monomers, fragrance fixatives and soluble additives (MW < 5,000 Da) in perfume and cologne concentrates to pass through smoothly and completely. The accurate MWCO setting achieves the dual goal of ultra-efficient fine particulate removal and 100% retention of aromatic components in fragrance concentrates, ensuring that the filtered concentrate is not only clear and pure but also retains the original fragrance profile and formulation characteristics designed by perfumers.

Membrane Thickness

This 10-inch daily chemical filter cartridge adopts a hydrophobic modified gradient winding filtration layer structure adapted to the fine filtration of perfume and cologne concentrates, with an effective functional filtration layer thickness of 2-5 mm and a total cartridge thickness (including high-purity PP inner core and gradient filtration layer) of a standard 28 mm, fully compatible with the installation size of small and medium-scale filter housings in the fragrance production industry. The filtration layer is composed of a thin, dense inner layer (1-2 mm) for ultra-fine interception of submicron particulates and a slightly loose outer layer (1-3 mm) for pre-interception of micro-scale impurities, forming a gradient thickness structure that balances high filtration precision and moderate dirt-holding capacity. The hydrophobic modified surface treatment of the filtration layer reduces the adhesion of fragrance concentrate components to the membrane surface, further lowering the pressure drop and avoiding the adsorption of aromatic components. The uniform thickness distribution of the filtration layer ensures consistent filtration efficiency across the entire cartridge surface, eliminating local dead zones and ensuring the uniform clarity of the filtered perfume and cologne concentrate.

Replacement Cycle

The replacement cycle of this 10-inch daily chemical filter cartridge is determined by the impurity content of the perfume/cologne concentrate, daily filtration volume and system pressure drop, with a recommended normal replacement cycle of 1-2 weeks for the fine filtration stage of perfume and cologne concentrates in small and medium-scale fragrance production enterprises. For high-purity perfume concentrates with ultra-low impurity content and small daily filtration volume (<20 L/day), the replacement cycle can be appropriately extended to 2 weeks for all precision models; for cologne concentrates with complex formulations, slightly higher impurity content or medium daily filtration volume (20-50 L/day), the replacement cycle is shortened to 1 week, especially for the 0.5/1 μm ultra-high precision models. In addition, the cartridge must be replaced immediately if any of the following conditions occur: the terminal pressure drop exceeds 0.05MPa, the filtration flux drops by more than 30% of the initial value, the filtered concentrate appears turbidity or particulate sedimentation, or the concentrate has an abnormal fragrance profile (caused by aromatic component adsorption), to ensure the continuous purity and clarity of perfume and cologne concentrates.
