Cleaning Validation Swab in Pharma

TOC YST-715A and other wiping sticks are suitable for wiping small and large planes, grooves, etc.

Cleaning Validation Swabs in Pharma are essential tools used in the pharmaceutical industry to ensure that manufacturing equipment and surfaces are properly cleaned and free from contaminants. Cleaning validation is a critical part of the Good Manufacturing Practice (GMP) standards and regulatory requirements (e.g., FDA, EMA), ensuring that products are manufactured in a clean environment to maintain their quality, efficacy, and safety.

The square head provides more contact surfaces between the wiping stick and the product to be wiped.

And the double-layer soft polyester dust-free cloth head has excellent Liquid absorption capacity and buffering force.

The polypropylene rod adopts the latest chemical formula, which not only has excellent chemical performance.

But also ensures the high cleanliness of the product.

The thick long rod provides more powerful support and a better wiping effect.

What is Cleaning Validation?

Cleaning validation is the process of verifying and documenting that the cleaning procedures consistently remove contaminants from equipment surfaces to levels that are considered safe and within acceptable limits. In the pharmaceutical industry, cleaning validation is particularly important to avoid cross-contamination between different drugs and to ensure that cleaning agents do not leave harmful residues.

Role of Cleaning Validation Swabs in Pharma

Cleaning validation swabs are used to collect samples from surfaces after cleaning procedures to test for residual contaminants, including:

1. Active pharmaceutical ingredients (APIs)
2. Cleaning agents or solvents
3. Microbial contamination
4. Residual dirt, dust, or other particulate matter

These swabs play a critical role in ensuring that cleaning procedures have been effective in reducing contamination to acceptable levels.

After sampling, it can be broken along the TOC sampling bottle at the breaking point port, avoiding the traditional swab to be cut with scissors, saving valuable laboratory personnel time.

Cleaning validation is a well-documented process that demonstrates that the cleaning of manufacturing equipment in the pharmaceutical industry is effective and consistent.

70% of the pharmaceutical companies in the country will use the TOC cleaning and verification wiping Cleaning Validation Swab to inspect and clean the inner and outer surfaces and dead corners of the equipment.

Remove the surface burrs, and make sure that the shaft can see the light, the groove can see the bottom, and the equipment can see the true colour. No oil stains, no debris. No standing water, no dirt. The inner and outer surfaces of the equipment are clean. And inspect equipment and components.

Product Features of Cleaning Verification Swabs:

• The wiper sticks produced by Yousite’s unique process are extremely clean.
• woven or non-woven materials wiping heads. Without the use of adhesives and have good acid and solvent resistance.
• Cleaning swabs sealed edges produce no loose fibres or particles. And the seams are strong and resistant to splitting, making them ideal for rubbing around protruding objects.
• The Class 10 (ISO Class 4) cleanroom treatment process guarantees ultra-low ionic and non-volatile residual content of the wiper bar. As well as ultra-low particle generation.

Common Applications of Cleaning Validation Swabs in Pharma:

1. Surface Sampling for Residuals:

   • After cleaning pharmaceutical production equipment (such as mixers, tablet presses, and filling machines), validation swabs are used to collect samples from surfaces (such as walls, trays, and tubes) to test for residual API, cleaning agents, or other contaminants.
   • The swabs are used in combination with swabbing protocols that define how and where the surface samples should be collected.

2. Microbial Contamination Testing:

   • Swabs are used to collect microbial samples from surfaces to test for bacterial or fungal contamination. This is an important part of ensuring that no pathogenic microorganisms are present in the manufacturing area or on equipment that could contaminate drug products.

3. Visual Inspection:

   • Swabs are sometimes used in conjunction with visual inspections to verify that equipment surfaces have been properly cleaned. Residues or visual dirt are collected using swabs, then tested to confirm that contamination levels meet required limits.

4. Pre-Validation Sampling:

   • Before initiating the cleaning validation process, swabs are used to collect baseline samples from surfaces. These are tested to identify initial levels of contamination before the cleaning process begins.

Popular Cleaning Validation Swabs Brands:

1. Texwipe:

   • Texwipe offers a wide range of cleaning swabs designed for pharmaceutical, biotechnology, and semiconductor industries. Their Cleanroom Swabs and Swab Sampling Systems are often used in cleaning validation procedures.
   • Example: Texwipe TX716 (Polyester Non-Woven, lint-free, ESD-safe swab).  TX714K

2. YOUSUTO:

   • Yousuto provides a variety of swabs, including non-linting foam and cotton-tipped swabs, specifically designed for cleaning validation and contamination control in the pharmaceutical industry.
   • Example:Yousuto Swab-PS series (ESD-safe, non-linting, and suitable for surface sampling).

How to Use Cleaning Validation Swabs:

1. Preparation:

   • Select the correct type of swab based on the surface you’re testing (e.g., foam-tip swab for flat surfaces or pointed-tip for crevices).
   • Ensure the swabs are sterile (if needed) and that the sampling area has been properly cleaned beforehand.

2. Swabbing:

   • Use the swab to collect a sample from the surface. Apply gentle pressure to ensure adequate contact with the surface while avoiding excessive force.
   • If pre-saturated swabs are used, ensure they are sufficiently moistened without over-saturating the surface.

3. Sampling Procedure:

   • Follow the specific sampling protocol for the area being tested, which may include specific methods for sampling (e.g., swabbing in a zig-zag pattern) or guidelines for how many samples should be taken.
   • Record the swabbing procedure to ensure proper documentation for the validation process.

4. Testing:

   • After collecting the sample, send it to a qualified laboratory for analysis. Tests can include residue analysis for APIs, testing for residual cleaning agents, or microbial testing.

5. Documentation:

   • Proper documentation of the cleaning validation process is critical for compliance. Record the batch or lot number of swabs used, the sampling locations, the number of samples taken, and the results from laboratory tests.
