At Heimtextil 2023 in Frankfurt, Devan Chemicals, headquartered in Ronse, Belgium, launched Purissimo NTL – a biobased and readily biodegradable allergen control technology.

It is based on probiotic encapsulation technology and can be applied to textiles during the finishing stage of the manufacturing process.

Worldwide, the prevalence of allergic diseases has continued to rise in the industrialised world for more than 50 years, according to the World Health Organisation. Purissimo NTL cleans up pet dander, pollen and house dust mite allergens in textiles throughout the home using encapsulated probiotics that are natural microorganisms similar to those found in yoghurt and cheese and have been used in textiles by Devan since 2010.

Purissimo NTL is based on Devan’s probiotics incorporated into a new microcapsule shell. The shell is based on a natural crosslinked biobased polymer,which results in microcapsules that are up to 97% biobased and readily biodegradable to OECD 301B specifications.

In the process, dormant probiotic bacteria spores are encapsulated and the microcapsule product is then integrated into the textiles. Friction opens the capsules and releases the spores which absorb humidity, self-activate and start to multiply. The probiotic bacteria consume the allergens that cause allergic reactions and asthma. Due to lower allergen concentration, individuals with respiratory allergies will experience milder-to-no symptoms.

Purissimo NTL can be used on a wide range of textiles such as mattresses, pillows, bedcovers, blankets and also upholstered furniture, carpets, curtains and public transportation, as well as pet items, such as bedding. It is Oeko-tex compliant, has a long-lasting effect and a wash durability up to 30 washes.
