EXCLUSION CRITERIA
- Volunteers who did not respect article L 209-17, law of 20 December 1988.
- Volunteers who participated in a test for the verification of the good cutaneous or peri-ocular local tolerance during the four last weeks and/or to active sensitisation type studies during the last six months.
- Volunteers who refused to sign the informed consent statement.
- Female volunteers, either pregnant or nursing mothers, or not using medically acceptable contraceptive methods.
- Volunteers having undergone organ excision (kidney, lung, spleen, liver), an organ transplant, a skull concussion with loss of consciousness since less than 5 years or with present after-effects.
Volunteers having:
- the following disorders: cardiovascular, pulmonar, digestive, neurologic, psychiatric, genital, haematological, endocrine, having a redhibitory aspect for the study concerned;
- an immunological deficit;
- a background of drug intolerance (local or general anaesthetics), and intolerance to cosmetics, to body hygiene or domestic products, to clothes, to products used at word such as cellophane, rubber (gloves, glues, adhesive tapes), nickel, aluminium....;
- an allergic background: asthma, periodic spasmodic rhinitis;
- a skin disease, and in particular: dermographism, urticaria, edema, eczema, recurrent herpes, herpes zoster having erupted less than three months before, pityriasis versicolor, common acne with a sudden rise of inflammation or nordular or kystic acne, psoriasis, ichtyosis , lichen planus, chronic lupus erythematodis, cheloid scars, pigmentary disorders (vitiligo, chloasma, multiple lentigines, numerous or congenital nevi, especially if they are of large size), hyperhidrosis, dorsal hyperpilosity, important perspiration;
- a febrile illness: more than 24 hours of fever within the 6 days prior to the first application of the test article.
- Volunteers having had or being in the course of a long-term treatment, in particular with antihistamine, steroids, Beta blocker collyriums, of desensitisation.
- Volunteers who recently suffered from insolation, or having followed heliotherapy during the month preceding the study.
- Volunteers smoking more than 10 cigarettes a day and not accepting restriction of their tobacco consumption during two days prior to the start of the study and throughout the whole study. - Ethical approval:
- confirmed, but no further information available
- Route of exposure:
- dermal
- Reason of exposure:
- intentional
- Exposure assessment:
- not specified
- Details on exposure:
- 0.02 mL of the test substance (as supplied) were applied on the back, on a surface of about 50 mm², on a filter paper and were occlusive covered with a "Finn Chamber" (aluminium disc) and held in place with an adhesive tape. The test article was applied only once. After an exposure of 48 h, patches were removed and substantial amount of remaining test material was removed using a hydrophilic pad. Concomitantly, chambers without test substance were applied as "negative" controls.
- Examinations:
- - Cutaneous examinations
Results and discussion
- Clinical signs:
- No reaction of pathological irritation and cutaneous intolerance were noted. No subordinate effects were observed.
- Results of examinations:
- SKIN EXAMINATION
No skin reactions were observed in the study.
Applicant's summary and conclusion
- Conclusions:
- The single epicutaneous application of the test substance under occlusive conditions for 48 h was well tolerated in healthy volunteers. Therefore, no indication for classification according to CLP/EU GHS criteria; no classification required according to Regulation (EC) No 1272/2008.
