The General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) recently carried out nationwide supervision and random inspections on the quality of detergents and white latex products. In the detergent inspection, samples were collected from 51 companies across 22 provinces, municipalities, and autonomous regions, totaling 68 products. Out of these, 65 passed the tests, resulting in a sampling qualification rate of 95.6%. For white latex products, 51 samples were taken from 9 provinces and municipalities, with 43 passing the tests, giving a pass rate of 84.3%.
During the detergent powder inspection, the main issues identified included an insufficient detergency ratio, which failed for two products. Another issue was the excessive free base content, which exceeded the standard in one product. This problem often arises when manufacturers increase the alkalinity to improve cleaning performance, but high levels of free base can damage fabrics over time.
In the white latex quality check, 17 large and medium-sized manufacturers produced all compliant products, while a few small enterprises had substandard outputs. One major concern was excessive formaldehyde content, with seven products having levels between 1.1g/kg and 1.5g/kg—above the national limit of 1.0g/kg. Additionally, some products had unqualified pH levels and viscosity. High pH can cause corrosion to wood surfaces, while poor viscosity may affect the initial adhesion and overall performance of the product.
These findings highlight the need for stricter quality control, especially among smaller manufacturers, to ensure that products meet safety and performance standards. Consumers are advised to choose products from reputable brands and pay attention to labels and certifications to avoid potential risks.
