Why is Hand Sanitizer Testing Important?

With the advent of a global pandemic, hand sanitizers have become a key part of our daily hygiene. Manufacturers have had to rise up to the ever-increasing demand while maintaining the efficacy and quality of the product at the same time. Hand sanitizer is applied to eliminate possible infection-causing pathogens and other microorganisms. As it is categorized under biocidal products, it must be tested thoroughly for its effectiveness and safety. Especially due to the impact left by COVID-19, most governments have established strict guidelines for producing and marketing hand sanitizers. As a result, hand sanitizer testing has emerged to be greatly functional in meeting the regulations and standards set for public safety. Keeping in mind the serious purpose of the tests, Test House is committed to being the most trusted testing lab in Chennai.

Hand Sanitizer Raw Material Testing

Testing begins right with raw ingredients which are used to produce hand sanitizers. The materials are screened for any impurities and the quality is verified meticulously. The most common tests offered in testing labs in Chennai are:


Alcohol Testing:

Ethanol, which is one of the major components of sanitizers, may contain harmful impurities. Ethanol and methanol content must be checked alongside ethanol purity to prevent any toxic effects.

Gas Chromatography (GC):

GC is used to separate volatile materials by their boiling points. As hand sanitizer is primarily made of volatile components like ethanol, methanol, n-propanol, and isopropanol, gas chromatography proves to be highly useful in separating them for further analysis.

Hand Sanitizer Efficacy Testing Methods

  • Most disinfecting products like hand sanitizers and hand washes are subjected to standards as stated below:
  • Antibacterial testing: Tested for the bactericidal potency of a medical-grade chemical disinfectant.
  • Antiviral testing: Quantitative suspension test useful to gauge the virucidal activity of sanitizers.
  • Fungicidal testing: Lastly, disinfectants and sanitizers used in the medical field are tested to check their fungicidal or pesticidal effect. This test is also applicable to hygiene products as well as surface disinfectants.

Hand Sanitizer Efficacy Testing Requirements

There are many international standards in place that dictate the criteria to be met for a hand sanitizer to be deemed acceptable. This ensures that the product is efficient enough for proper functionality.

Some of the testing requirements are as follows:

  • Test microorganisms 
  • Contact Period
  • Testing conditions like temperature
  • Substance interference
  • Growth curve log reduction value

As hand sanitizers are a crucial part of healthcare and hygiene, manufacturers must maintain a supply of products that are up to date on all spheres of testing and standards. At Test House, we offer a wide range of options for hand sanitizer testing in Chennai at your disposal. We constantly strive to be on top of new conditions or requirements to be fulfilled for hand sanitizer testing manufacturers in Chennai.

What is the laboratory test for soap? What is the test method for soap?

There are several laboratory tests used to evaluate the quality and properties of soap. Some of the common tests include: 1. pH Test Purpose : To determine the acidity or alkalinity of the soap. Method : A small amount of soap is dissolved in distilled water, and the pH is measured using pH paper or a pH meter. The ideal pH for soap is usually between 9 and 10. 2. Total Fatty Matter (TFM) Purpose : To measure the percentage of fatty matter in the soap, which indicates its quality. Method : The soap is dissolved in alcohol, and the fatty matter is extracted using an organic solvent like petroleum ether. The solvent is then evaporated, and the residue is weighed to determine the TFM content. 3. Free Alkali Test Purpose : To measure the amount of free alkali present in the soap, which can cause skin irritation. Method : The soap is dissolved in ethanol, and the solution is titrated with hydrochloric acid using phenolphthalein as an indicator. 4. Moisture Content Purpose : To determine the...
