Calling Attention Related to Dermatitis Caused by Wearing Blouse for Ladies

The onset cases of the dermatitis by wearing clothes, etc. were often found in the accident information collected by the Ministry of International Trade and Industry. Therefore, the National Institute of Technology and Evaluation (NITE) performed tests for the "blouses for ladies" having caused the dermatitis by wearing, and obtained the results that allergic contact dermatitis was developed by the dye used for dying the fabric. To prevent the similar accidents from reoccurring, the NITE decided to provide the information related to the accident.

1. Accidents Occurrence Situations

When a user worn a blouse for the lady for half a day, parts of her body being in contact with the fabric of the blouse such as the both shoulders, the breast part, and the back part became itchy and red.The sufferer was diagnosed as the allergic contact dermatitis1)by a doctor of the dermatology.

  1. 1) The allergic contact dermatitis
    The allergic reaction is one of the defense reactions of a human body and, when some substance enters into the body and the entered substance is regarded as a foreign body, the appropriate person feels sever itch as the defense reaction. When a causal substance is absorbed through the skin by the contact and shows the allergic reaction, it is called the allergic contact dermatitis.

3. Origins of Accident

To clarify the origins of the accident, a chemical analysis and a patch test 2) by detection components were performed to find that the sufferer got the allergic contact dermatitis by three types of dyes (red disperse dye (C.I. disperse red 82), orange disperse dye (C.I. disperse orange 30), and blue disperse dye (C.I. disperse blue 124)) out of the six types of dyes used for dying the acetate. Among them, the major causal substance was the blue disperse dye (C.I. disperse blue 124).

  1. 2) Patch test
    The patch test which examines whether the inflammation occurs or not by sticking a seal containing a suspicious substance as the origin of the dermatitis on the skin of the sufferer and waiting for a prescribed time elapse was performed by the doctor of the dermatology with the consent of the sufferer in a medical institution.

4. Matters Required Attention

The disperse dyes, or the causal substances of this accident and dying processing are designated by neither law nor administrative notification regulating the toxic substances contained in the fiber product so that its appropriateness/inappropriateness related to the safety standard cannot be determined.

Moreover, there are individual variations whether the allergic contact dermatitis appears or not according to the physical constitution and the contact frequency with a chemical substance.

Though there are individual variations in its onset, the blue disperse dye (C.I. disperse blue 124), which was the major accident origin, was drew attention recently as the causal substance of the allergic contact dermatitis by the Japanese Society for Contact Dermatitis and from the viewpoint of preventing the similar accident to this from reoccurring, the NITE provides the information to the consumers, related industries, and National Consumer Affairs Center so as to call the attentions.
