There are four key microbes found in a healthy and balanced scalp microbiome:
The certification procedure for Standard 39.10 –
The textile product goes through four test runs as part of the
All textiles are washed in our laboratory according to a standardized procedure.
Hygiene products are sterilized through UV light exposure.
The balance between S. epidermidis (the most common skin bacterium) and the harmful effects of the S. aureus bacterium should not be disturbed by the product. A co-culture with both bacteria is mixed with the product for a certain duration and then the ratio of the two microbes is compared with the untreated control group. Under the influence of the textile product, the balance must not tip in favor of S. aureus.
We begin by culturing microbes typical for the scalp microbiome. For Standard 39.10 - Scalp these include M. globosa, M. furfur, C. acnes and S. epidermidis.
The co-cultures are exposed to the product to be tested for a specific duration and the change in diversity is compared with the untreated control group—this is done analogue to the balance test.
The diversity of the key microbes found in the scalp microbiome must be preserved.
A Microbiome-friendly textile product should both preserve microbial diversity and pose no detriment to microbial growth. The test uses a model to simulate skin contact. Each key microbe is placed in direct contact with the textile.
"Each of us wears clothes on his body almost 24 hours a day. At work, during sports and even at night. But is that always healthy? Products certified with our textile seal protect the skin microbiome and alleviate the risk of imbalances and resulting skin diseases."
