Antialgal Testing
Fungicidal/Yeasticidal testing guidelines specify laboratory test procedures to assess the efficacy of antifungal-coated test products or disinfectants.
Fungi are ubiquitous, however, they tend to grow more quickly in moist or humid conditions. This rapid growth of fungi/yeast on any surface leads to unsightly discoloration, foul odor, accelerated structural damage, and can also result in serious health risks. Hence, there is an increased demand for antifungal/anti-yeast agents that can prevent damages caused by fungal/yeast growth and thus preserve the aesthetic value and shelf life of the coated material.
Similarly, antifungal treatments are done to fabric materials. Thus, preserving the original color of the fabric and preventing any foul odor due to fungal/yeast growth.
Till date, fungicidal/yeasticidal products available in the market are predominantly in the form of paints, coatings, and disinfectants. Such speciality products are formulated using active fungicidal/yeasticidal agents.
Introduction to Fungicidal/Yeasticidal Testing
Development of fungicidal/ yeasticidal products involves multiple steps and processes which differ depending on the need of their intended use. International organizations like EN (European standards), ISO (International Organization for Standardization), ASTM International (formerly American Society for Testing and Materials), and a few more have developed and published a wide range of standard guidelines to test different kinds of fungicidal/yeasticidal products. These standards specify the testing conditions, test microorganisms, and the passing criteria to ensure the product is able to satisfy its efficacy claims.
These standards have been used by manufacturers worldwide to evaluate the antifungal efficacy of the final product.
Fungicidal/Yeasticidal Testing Methods For Paints/Coatings and Plastics at MIS
At MIS, we offer customized solutions to our clients according to their fungicidal & yeasticidal testing needs!
- ASTM G21 – A variety of polymer materials can be tested using ASTM G21. This antifungal efficacy test is applicable for both indoor and outdoor furnishings that include molded and fabricated articles, tubes, rods, coatings, pipes, marine plastics, sheets, and film materials.
- ASTM C1338 – ASTM C1338 test helps to determine the quality and effectiveness of newly manufactured insulation products under favorable lab-controlled conditions to resist fungal growth.
- ASTM D5590 – ASTM D5590 is an antifungal testing method which is used to determine the resistance of paints/coating materials to fungal defacement under optimal lab conditions.
- ASTM D3273 – ASTM D3273 test is a qualitative antifungal test to assess the resistance of interior coatings against mold and fungus growth. This 28 days test is conducted in an environmental chamber stimulating real environmental conditions to evaluate the antifungal performance of sample materials.
Role and applications of Fungicidal & Yeasticidal Testing Services
Fungicidal and yeasticidal testing services play a vital role in ensuring that products effectively combat fungal and yeast contamination. These tests help manufacturers validate antimicrobial claims, comply with regulatory standards and maintain product integrity and durability.
Textiles & Fabrics
Fungi and yeasts thrive in damp conditions, leading to mold growth and fabric deterioration. Testing fungicidal/yeasticidal efficacy of textiles ensures resistance to fungal colonization in humid environments.
In medical settings, hospital linens and bandages require strict fungal resistance to maintain sterility and prevent infections. Outdoor and sportswear fabrics also need protection against fungal growth to extend their lifespan and usability.
Disinfectants
Fungal contamination in hospitals, public spaces, and industries can lead to severe health risks. Disinfectants claiming to have fungicidal and yeasticidal properties need to be tested for their intended usage.
Industrial sanitizers used in food processing and pharmaceutical environments need to meet efficacy standards to maintain hygiene and prevent product spoilage. Personal hygiene products such as hand sanitizers and wipes should be tested to ensure they prevent fungal infections and contamination.
Plastics & Polymers
Plastics and polymers used in packaging, industrial applications, and consumer products are vulnerable to fungal degradation, which affects their durability and usability. Testing ensures that packaging materials remain free from fungal contamination, particularly in food and pharmaceutical industries. Biopolymers and industrial plastics require enhanced durability to resist microbial attack. Automotive and construction materials must also maintain fungal resistance, especially in high-humidity environments where microbial growth is more likely.
Paints & Coatings
Moist environments promote fungal growth on walls, surfaces, and coatings, leading to both aesthetic and structural damage. Architectural paints should be tested for resistance against fungal growth, especially in humid areas. Industrial coatings must prevent fungal colonization on machinery, pipelines, and storage tanks to ensure operational efficiency. Protective coatings used in medical and food processing environments require rigorous testing to meet strict hygiene standards.
Cosmetics & Personal Care Products
Cosmetic formulations must be free from fungal contamination to ensure product safety and consumer health. Preservatives in creams, lotions, and makeup should be tested for efficacy in inhibiting fungal growth. Shampoos, body washes, and other skincare products must remain uncontaminated to avoid health risks. Organic and natural cosmetics, which often use fewer synthetic preservatives, require specialized testing to confirm antifungal efficacy without compromising product safety.
