- MARZULLI-MAIBACH METHOD: The Marzulli-Maibach test is a reference test to study the sensitizing potential of a product. The investigational product was applied under maximized conditions (occlusion) during 3 weeks (Induction phase). After a two-week resting period, the investigational product was re-applied on the same site (Challenge phase). If the investigational product was allergenic, it induced a cutaneous reaction during the challenge phase.

- Executive summary:
A cutaneous tolerance and sensitizing potential study of the investigational product, PATCHOULI FRACTION (ALPHA GUAIENE) 290737 8% (3646µg/cm2) EtOH/DEP(25/75) lot 1928083 tested undiluted was conducted by patches application, according to the Marzulli-Maibach sensitization method. The data of 102 female and male subjects aged from 19 to 63 years old were analyzed during the study. The subjects were willing and able to give a written informed consent. The study was carried out at the clinical unit of Skopje in MACEDONIA. The study was blinded and randomized.
Duration:Induction phase: 3 weeks (3 times a week during 48 hours or 72 hours); Duration Resting phase: 14 days; Challenge phase: 1 week (once during 48 hours)
INDUCTION PHASE: During the Induction Phase, the investigational product was applied (160 µL) on a predetermined site under semi occlusive patch (back). A semi-occlusive patch receiving no product was applied in the same conditions and was considered as a non-treated control. Each time, the patches (treated and non-treated) remained applied during 48 or 72 hours before removal and replaced on the same site.
RESTING PHASE: During the 14-day Resting Phase, no product was applied on the sites used during the Induction phase or on the contralateral split-back which was used during the Challenge phase.
CHALLENGE PHASE: During the challenge phase (Day 34/36*), the investigational product was applied under semi occlusive patch on the induction sites and on the contralateral sites. A semi occlusive patch receiving no product was applied in the same conditions and was considered as a non-treated control. The patches (treated and non-treated) remained applied during 48 hours and removed afterwards.
A clinical examination was performed by the investigating dermatologist during the Induction Phase on Days 1, 3,5/6,8, 10,12/13,15, 17,19/20and22/24,and during the Challenge Phase on Days34/36, 36/38, 37/39and38/40.
During the induction phase, no sign was observed on the control site and the investigational product site. During the challenge phase, no sign was observed on the control site and on the investigational product site, neither on the homolateral side nor on the controlateral site. In this study, no adverse event or serious adverse event was observed by the investigating dermatologists. No significant clinical manifestation of intolerance or allergy was observed by the investigator. The investigational product presents an irritation index of: Z = 0.000; the investigational product is therefore considered as practically non-irritant.
Under the conditions of the study, the investigational product PATCHOULI FRACTION (ALPHA GUAIENE) 290737 8% (3646 µg/cm2) EtOH/DEP(25/75) lot 1928083 tested undiluted, under semi occlusive patch, can be considered as non-sensitizing.
- Endpoint:
- skin sensitisation: in vitro
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- an in vitro skin sensitisation study does not need to be conducted because adequate data from an in vivo skin sensitisation study are available

Justification for classification or non-classification
In a human repeat insult patch test, the test item was concluded to be non-irritating and non-sensitising.
Based on this result and due to the nature of the main constituents of the registered substance, the registered substance does not need to be classified as skin sensitiser.
