25 June 2009, Elon, NC - New textile testing methods
developed by scientists at the Hohenstein’s Institute for Hygiene and
Biotechnology now enable Hohenstein to certify textile products as
hypoallergenic. A unique testing process analyzes a fabric’s interaction with
living skin cells to determine whether it is likely to induce an allergic
reaction or skin irritation in the wearer. Textiles that pass the test series
may be certified by Hohenstein as hypoallergenic, skin-friendly fabrics that
will not irritate sensitive users.
“Skin sensitivity to allergens is a rapidly growing concern
with many consumer audiences,” says Dr. Dirk Höfer, the department’s director.
“A manufacturer’s ability to state that his textile products have been tested
and are certified as hypoallergenic is a significant advantage. Hohenstein’s
certification will be of particular interest to companies that make textile
products for infants and children as well as for the intimate apparel,
bodywear, legwear, activewear, medical devices and textiles, and household
textile markets.”
According to the Asthma and Allergy Foundation of America,
50 million Americans suffer from allergen sensitivities. A 2008 National Center
for Health Statistics report indicated that of the 3 million children suffering
from food allergies (up 18% in the decade), a third also have skin
sensitivities. Scientists have identified more than 3,700 substances as skin
allergens.
“Consumers are exposed to more potential skin allergens
today than ever before,” says Sam Moore who heads Hohenstein America. “The
textile products market has many new types of fibres and fabrics that are made
all over the world with new textile processing chemicals and dyes. This growth
in innovation has also contributed to the increasing presence of potential skin
irritants. For the sensitive consumer, that can be distressing.”
Hohenstein’s hypoallergenic testing evaluates textiles on
two key criteria. First, testing determines that fabrics do not cause chemical
damage to the human skin cells (cytotoxicity). Second, it is ascertained that
the fabrics do not elicit a stressful response from the skin cells which would
indicate a potential allergic reaction.
Hohenstein Institute is a leading provider of Oeko-Tex
Standard 100 certification which tests textile products to ensure that they do
not contain harmful levels of more than 100 substances believed to be dangerous
to human health. Hohenstein’s hypoallergenic certification complements Oeko-Tex
certification to reassure consumers that textile products have been tested and
verified as both safe and non-irritating to human skin.
