Mandatory Analyses and Quality Testing for Surface Cleaners
For surface cleaners, in addition to high cleaning performance, safety, stability, environmental compatibility, and compliance with legal requirements are of great importance. Therefore, manufacturers can approach us to conduct numerous physical, chemical, microbiological, and toxicological analyses to verify the accuracy of the formulation, its efficacy, and regulatory compliance.
Fundamental Tests and Analyses for Surface Cleaners
pH Analysis: Determines the acidic, neutral, or alkaline composition of the product. This is crucial for user safety, preventing surface damage, and ensuring formulation stability.
Density Determination: Determines the ratio of the product's volume to mass. This is essential for adherence to production standards and accurate filling processes.
Viscosity Analysis:
Determines the flow properties. It is evaluated concerning surface adhesion, application feel, and compatibility with the spray mechanism.
Determination of Anionic and Non-ionic Active Ingredients: Measures the quantity of surfactants, which are fundamental determinants of cleaning performance. This is performed to control formulation accuracy.
Total Active Matter (TAM): Calculates the proportion of active ingredients that determines the product's overall cleaning performance. This is crucial for performance optimization and regulatory compliance.
Fragrance and Dye Analysis: Performed using GC-MS and spectrophotometric methods. This is essential for controlling allergen content and ensuring chemical stability.
Grease Removal Test: A performance test that evaluates the detergent's ability to remove grease and dirt under practical conditions.
Foam Test: Measures foam formation and stability. This test is conducted to develop a product that meets consumer expectations.
Biodegradability Analysis: Evaluates, in accordance with OECD test methods, whether the surfactants are environmentally compatible.
Toxicity (OECD 201–203):
Measures acute toxicity to aquatic organisms:
- OECD 201: Algal Toxicity
- OECD 202: Acute Toxicity to Daphnia
- OECD 203: Acute Toxicity to Fish
Microbiological Contamination: Includes total aerobic microbial count, yeast and mold, and pathogen analyses. This indicates product reliability.
Heavy Metal Analysis: Heavy metals such as Pb, Cd, Hg, and Cr are controlled using ICP-MS/ICP-OES. This is crucial for both environmental and human health.
Packaging and Label Conformity: The suitability of the packaging material for the product, its integrity, chemical interaction, and label durability are evaluated.
Stability Tests: Accelerated aging and shelf-life tests measure the product's resistance to spoilage or degradation over time.
SDS Accuracy Check: It is verified whether the actual formulation matches the Safety Data Sheet (SDS). This is required for regulatory compliance.
