Interpretation of Key Inspection Points for Cosmetics Production Quality Management: Water Treatment System
Helpful Tips
Foreword:
This issue provides an interpretation of Items 42-43 of the "Key Inspection Points for Cosmetics Production Quality Management" (Actual Production Version), focusing on the water treatment system and its management system requirements, for your reference.
-
The term "Enterprise" in this series of articles collectively refers to Registrants, Filers, and entrusted manufacturers. "Legal Representative" refers to the enterprise's legal representative or the person acting on their behalf with overall management responsibility for the enterprise.
-
Items marked with "#" in this series of articles involve a comprehensive assessment based on employee interviews, document reviews, and on-site observations to determine compliance with the clause requirements.
01: Hardware Requirements for Water Treatment Systems
Enterprises shall determine the requirements and quality standards for process water based on the variety, quantity, process and quality requirements of the cosmetics produced, as well as the production license items, and shall equip with an appropriate water treatment system.
(1) Process water is a specialized category of production water, typically produced through methods such as reverse osmosis, ion exchange, or distillation, with a quality significantly higher than that of ordinary production water.
(2) Process water generally includes water used in products, laboratory water, and water for the final rinse step of inner packaging materials, equipment, and utensils that come into direct contact with raw materials or product contents.
(3) The water treatment system consists of water purification equipment, storage tanks, disinfection facilities, transfer pumps, and piping. All storage tanks and pipes should be clearly labeled with their contents (e.g., raw water, purified water, wastewater) and flow direction.
(4) The design, installation, operation, and maintenance of the water treatment system must ensure that the process water meets the required quality standards. The water production capacity should be compatible with the production scale.
Evidence to demonstrate:
① Records of water treatment equipment procurement, installation, and validation.
② Water treatment process flow diagram.
③ Water treatment system operation records.
④ Process water quality standards (or relevant documents).
⑤ Process water quality monitoring records.
⑥ On-site inspection of the water treatment system setup and operational status.
-
Mismatch between water production equipment/capacity and production scale.
-
Failure of water treatment facilities and conveyance systems to operate normally.
-
Significant water leakage observed after activating the water production equipment.
-
Water storage tanks were not airtight, lacked breathing filters, and water overflow was present on-site.
-
Pipes in the water production room lacked labels indicating contents and flow direction.
02: Water Treatment System Management System
Enterprises shall establish and implement a water treatment system management system (or relevant documentation), and conduct regular cleaning, disinfection, monitoring, maintenance, and servicing of the water treatment system to ensure water quality meets product quality and production process requirements.
(1) Key parameters during the operation of the water treatment system shall be monitored and recorded, such as feed water/membrane/concentrate pressure, purified water/concentrate flow rate, and conductivity at various stages.
(2) A process water quality standard and monitoring plan shall be established. Regular monitoring shall be conducted for indicators such as color, odor, pH, conductivity, and total bacterial count, with monitoring records retained for reference.
(3) A cleaning and disinfection plan along with standard operating procedures for the water treatment system shall be established. Regular cleaning and disinfection shall be performed on the water purification unit, storage tanks, pipelines, etc., with corresponding records retained for reference.
(4) A maintenance plan and standard operating procedures for the water treatment system shall be established. Regular replacement of pre-filters, quartz sand, activated carbon, RO membranes, UV lamps, etc., shall be carried out, with corresponding records retained for reference.
Evidence to Demonstrate:
-
Water treatment system management system (or relevant documentation).
-
Water treatment system cleaning and disinfection records.
-
Water treatment system maintenance plan and maintenance records.
-
Water treatment system operation records.
-
On-site review of the water treatment system's operation and maintenance status #.
Unannounced Inspection Cases:
-
Water production equipment lacked maintenance procedures and operating instructions; no process water quality standard had been established.
-
The purified water system only recorded startup status, with no related operational data records, maintenance records, or cleaning/disinfection records available.
-
Severe scale buildup was found on the raw water flow valve of the water treatment equipment, and the flow meter contained scale and mold stains.
-
No records were retained for the replacement of filter media (quartz, activated carbon) during maintenance of the water treatment equipment.
Jinzong Enterprise has been specializing in the production and R&D of industrial pure water equipment for over 10 years, providing high-quality water production equipment for cosmetics manufacturing.
Jinzong Industrial Pure Water Equipment primarily adopts reverse osmosis technology, commonly referred to as RO deionized water equipment. Reverse osmosis is a membrane separation technology that utilizes a selective permeability (semi-permeable) membrane and relies on pressure as the driving force. When the pressure applied within the system exceeds the osmotic pressure of the feed water solution, water molecules continuously pass through the membrane, enter the product water channel, flow into the central pipe, and exit at one end. Impurities in the water, such as ions, organic substances, bacteria, and viruses, are retained on the feed side of the membrane and are subsequently discharged through the concentrate outlet, thereby achieving separation and purification.
The equipment features high efficiency, fully automated operation, and easy operation and maintenance. It enables continuous production, reducing labor intensity. Online conductivity monitoring ensures the effluent meets requirements. It can remove over 98% of organic substances and bacteria.
