Abstract:
Probiotics have been used in human health for over 45 years. More recently, micro-organisms have been incorporated into cleaning formulations creating a new category: Microbial-based cleaning products (MBCP). The peer-reviewed literature on MBCP remains limited; however, manufacturers commonly attribute efficacy to three principal mechanisms: secretion of extracellular enzymes, competition with other micro-organisms for nutrients and space, and production of antimicrobial agents such as antimicrobial peptides. Fabric care MBCP (e.g. probiotic-containing laundry detergents) represent a relatively recent commercial development and are currently available from a limited number of manufacturers. In laundry applications, probiotics are proposed to be delivered to fabric surfaces during the wash cycle and deposited onto textiles via agitation in the wash liquor. This contrasts with hard-surface cleaners, in which probiotics are applied directly (e.g. by spray, mop or sponge). Further experimental work is required to define conditions that maximize deposition and retention of probiotics on textiles and establish cleaning performance. Given that clothing soils often differ from hard-surface soils, strains intended for fabric care MBCP should be selected to favour germination and enzyme production relevant to laundry soils.
Insights
Microbial-Based Cleaning Products (MBCP) use beneficial microbes for cleaning. Fabric care MBCP, like probiotic laundry detergents, require more research for optimal textile deposition and cleaning efficacy.
Area of Science:
- Microbiology
- Consumer Products
- Textile Science
Background:
- Probiotics have a long history in human health.
- Microbial-Based Cleaning Products (MBCP) are emerging, utilizing microorganisms for cleaning.
- MBCP efficacy is often attributed to microbial enzymes, competition, and antimicrobial peptide production.
Purpose of the Study:
- To review the current state of Microbial-Based Cleaning Products (MBCP), focusing on fabric care applications.
- To highlight the limited peer-reviewed literature on MBCP, particularly for laundry detergents.
- To identify key mechanisms of MBCP action and areas for future research in textile care.
Main Methods:
- Literature review of peer-reviewed studies on Microbial-Based Cleaning Products (MBCP).
- Analysis of proposed mechanisms for MBCP efficacy in cleaning formulations.
- Comparison of probiotic application methods in hard-surface cleaners versus fabric care products.
Main Results:
- The scientific literature on MBCP is limited.
- Manufacturers commonly cite enzyme secretion, microbial competition, and antimicrobial peptide production as key mechanisms.
- Fabric care MBCP, such as probiotic laundry detergents, are a recent development with specific application challenges.
Conclusions:
- Further research is needed to optimize probiotic deposition and retention on textiles for effective laundry cleaning.
- Strain selection for fabric care MBCP should consider germination and enzyme production tailored to laundry soil types.
- Understanding the unique challenges of fabric care MBCP is crucial for product development and efficacy validation.
