OccurrenceThis section has been translated automatically.
- PTBP-F-R is used in adhesives, especially for bonding leather and rubber products, because it adheres particularly well to their surfaces, is flexible and durable. Therefore PTBP-F-R can be found in corresponding leather products, i.e. in shoes, handbags, belts and watch straps.
- Occupational exposures arise primarily during the bonding of leather in shoe factories and shoemaker's workshops. For more than 30 years PTBP-F-R has been known to be a frequent allergen for shoemakers.
EffectsThis section has been translated automatically.
- A sensitization against PTBP-F-R is not caused by the through-polymerized resin but by low-molecular reaction products and only very rarely by the two basic chemicals formaldehyde and p-tert-butylphenol (PTBP).

Clinical pictureThis section has been translated automatically.
- The allergic contact eczema caused by PTBP-F-R often appears clinically as hyperkeratotic-rhagadiform eczema of the fingers and palms.
- In addition, the face may also be affected by a dislocated contact dermatitis due to allergen carry-over.
Note(s)This section has been translated automatically.
- In the MdE assessment, the effects of a contact allergy to PTBP-F-R are usually only minor. However, if, for example, it is proven to be completely impossible for the person affected to wear safety shoes due to the sensitization to PTBP-F-R, the effects can also be higher.
- In many cases, no information can be obtained as to whether a particular shoe contains PTBP-F-R or not; the selection of suitable shoes for patients with sensitization to PTBP-F-R is therefore often difficult.
