Mandatory Analyses and Quality Controls for Wet Wipes: A Comprehensive Guide for Manufacturers
Wet wipes are practical products widely used in many areas such as personal care, hygiene, and, in recent years, even household cleaning. However, as they have a direct impact on consumer health, numerous parameters such as safety, microbiological quality, formulation accuracy, and packaging integrity must be meticulously examined. Through wet wipe analyses, we determine product safety upon skin contact, its efficacy, moisture stability, and compliance with regulations. Learn more about our scope of services.
Fundamental Tests and Analyses for Wet Wipes
pH Value (Extract Solution): The pH value of the extract solution obtained from the wet wipe fibers is determined. This is crucial for skin compatibility, reducing the risk of irritation, and ensuring formulation stability.
Moisture/Dry Matter Determination: The moisture content and dry matter percentage of the product are measured to assess the formulation's consistency. Moisture content is a critical parameter for the product's performance and sensory feel during use.
Preservative Efficacy (Challenge Test): Measures the effectiveness of preservatives in the product against microorganisms. Conducted in accordance with EN ISO 11930, it ensures the product's safety throughout its shelf life.
Microbiological Purity: Total aerobic microbial count, yeast and mold analysis, and pathogen control are performed. This is essential for hygienic production and consumer safety.
Total Active Ingredient (for Cleaning Wipes): For wet wipes used for cleaning purposes, the surfactant content is determined. This indicates the product's cleaning efficacy and the accuracy of its formulation.
Fragrance and Allergen Analysis: The fragrance components and potential allergens in the product are evaluated. This is required for compliance with European Union regulations and is crucial for sensitive skin.
Heavy Metal Analysis: Heavy metal levels such as Pb, Cd, Hg, and Cr are controlled using ICP-MS/ICP-OES methods. This is particularly important for baby and personal care wipes.
Biodegradability: The environmental compatibility of the fiber material used is assessed. This is an important test for manufacturers aiming to develop environmentally friendly and sustainable products.
Stability Test (Moisture Protection): Parameters such as moisture loss, shape alteration, or color change within the packaging are monitored. The objective is for the product to remain stable throughout its entire shelf life.
Packaging Compatibility: The chemical and physical interaction of the packaging material with the product is tested for integrity and durability. This is a crucial step to prevent the drying out of wet wipes.
Label Compliance Verification: The conformity of the product label with regulations (Biocidal Products, Cosmetics, or Detergent Regulations) is assessed. Subtitles, warnings, ingredients, and usage instructions are reviewed.
SDS Verification (Safety Data Sheet): The composition of the wet wipes is cross-referenced with the SDS. The verification is conducted in accordance with REACH/CLP requirements.
