Probiotics reconfigure the nappy industry: from antibacterial revolution to a new era of environmental degradation

In recent years, probiotic technology has quietly expanded from the food industry to the hygiene products industry, with innovations emerging especially in the application of baby nappy products.

A microbe-led technological revolution is quietly taking place in the hygiene products sector. Traditional nappies rely on chemical bacteriostats to protect babies' skin, but it is difficult to avoid the risk of allergies caused by chemical residues and the micro-ecological imbalance that can result from long-term use. We have therefore developed a new solution - specific probiotics that are immobilised on the surface of the nappy fibres by means of microencapsulation technology and precise formulations. These active microorganisms continuously metabolise and produce bacteriocins, organic acids and other substances that effectively disrupt the cell membranes of disease-causing bacteria such as E. coli and Staphylococcus aureus, resulting in an antibacterial effect.

With increasingly stringent global requirements on carbon emissions, the environmental attributes of nappies, as a high-frequency consumable, have become an important factor for consumers when shopping. Environmentally friendly and biodegradable products have become an important development direction for the hygiene products industry. Probiotic technology has also shown amazing potential in this area.

The synthetic fibre materials used in traditional nappies face the environmental challenge of taking hundreds of years to complete the degradation process. This emerging technology uses yeast and other microorganisms to synthesise bio-based nonwovens that can be efficiently degraded under specific burial conditions, significantly shortening the degradation cycle. Compared to bamboo fibre, this microbially synthesised nonwoven not only meets the same environmental standards, but also has a softer and smoother feel, meeting consumers' needs for both comfort and environmental friendliness. The microbial synthesis pathway for this eco-friendly material is not limited to the nonwoven substrate. Industry innovators are also applying probiotic metabolites to key components such as biodegradable adhesives and Super absorbent polymer, driving the green transformation of the entire industry chain.

A new generation of antibacterial, protective and eco-friendly nappies is moving from the production line to the home as technology continues to evolve and industry norms are established. This soft material that wraps around a baby's skin has become an innovative frontier for the symbiosis of microbial technology and human health.
