Results and discussion

Results of examinations:

No irritation was observed. One patient, out of 420 with eczema tested (0.24%), showed allergy to glycerol. This particular patient is on the staff of the allergy laboratory of the dermatological clinic in Helsinki. In january 1976, she noticed eczema on both hands. According to her own observations, a mixture of glycerol (1 part) and 70% ethanol (9 parts) applied on the hands after washing them with soap and water was the apparent cause of the ecezma. Glycerol tested at 1, 5 and 10% in water and the glycerol-ethanol mixture, as is, gave 3+ reaction at 48 and 72-hour readings. The reactions were considered to be allergic. The patient stopped using the glycerol-ethanol mixture, and the eczema disappeared within a couple of days.

Applicant's summary and conclusion

Conclusions:

In a study of 420 patients with eczema, 419 showed no irritation or sensitization. One individual reportedly was sensitized but the study design does not prove that.

Executive summary:

In a study of 420 patients with eczema, 419 showed no irritation or sensitization when tested with a 50% solution in water. One individual reportedly was sensitized but the study design does not prove that.
