Dishwashing Detergent Analyses: Mandatory Tests for Safety, Performance, and Legal Compliance
Whether for private or industrial use, numerous factors such as grease-dissolving power, foaming performance, skin compatibility, and environmental impact determine the overall quality of dishwashing detergents. Consequently, during the production of dishwashing detergents, it is imperative to assess not only their cleaning efficacy but also their microbiological safety, biodegradability, toxicity, and packaging compatibility. In this regard, we invite you to explore our services.
Tests and Analyses for Dishwashing Detergents
pH Analysis: Determines the acidic/basic nature of the detergent. The pH value directly influences the product's skin compatibility, cleaning effectiveness, and stability.
Determination of Anionic Active Ingredient: This measures the quantity of anionic surfactants, which constitute the fundamental cleaning power of dishwashing detergents. This directly correlates with the product's grease-dissolving capability.
Analysis of Non-ionic Active Ingredients: Non-ionic surfactants play a crucial role, particularly in dissolving fat-based soils. This analysis demonstrates the accuracy and efficacy of the product formulation.
Total Active Matter (TAM): Determines the total proportion of all surfactants in the detergent. A high TAM value indicates strong cleaning performance.
Foam Test: The foaming capacity of the detergent and the stability of the foam are evaluated. Foam formation has a direct impact on consumer perception, especially for hand dishwashing detergents.
Grease Removal Efficacy: The grease-dissolving power of the dishwashing detergent is measured through tests using standard grease mixtures or greasy surfaces. This is one of the most critical analyses, reflecting the product's actual functionality.
Fragrance Analysis: The integrity and stability of the fragrance components are examined. It is assessed whether the fragrance is affected by oxidation, heat, or light exposure.
Color Determination (CIE Lab)*: The product's color is measured spectrophotometrically to verify conformity with the standard. Color changes can indicate an alteration in the formulation.
Phosphate/Phosphorus Content: The use of phosphate in detergents is subject to environmental regulations. This analysis determines whether the product's phosphate content complies with legal limits.
Biodegradability Test: To assess the environmental impact of the detergent, the biodegradability of its surfactants is measured. This is conducted in accordance with OECD standards.
Acute Aquatic Toxicity (OECD 201–202–203): The potential toxic effects of the product on aquatic organisms are evaluated. This is one of the mandatory tests for environmental impact assessment.
Heavy Metal Analysis (Pb, Cd, Hg, As, etc.): It is verified whether the detergent's formulation contains undesirable heavy metal residues or those resulting from contamination.
Stability and Viscosity Tests: The product is tested under conditions such as temperature changes, light exposure, and storage to investigate issues like phase separation, viscosity alteration, and changes in color/odor.
Packaging Compatibility Test: It is examined whether the detergent reacts with the packaging material and if issues such as bloating, cracking, or leaks occur.
Label Conformity Verification: The product label is checked for the ingredient list, warnings, usage instructions, and legally mandated information. This is a critical process, especially for export products.
Microbiological Purity Analysis: By measuring bacterial, yeast, and mold counts, it is determined whether the product is microbiologically safe. Water-containing detergents are susceptible to microbiological contamination.
SDS (Safety Data Sheet) Accuracy Verification: The information in the SDS document – active ingredient percentages, hazard classes, technical values – is compared with the analysis results. An accurate SDS is essential for both legal compliance and occupational safety.
