- Inclusion criteria:
Individuals eligible for inclusion in the study where those who:
1: were males or females, 18 years of age or older, in general good health,
2: were free of any systemic or dermatologic disorder which, in the opinion of the investigative personnel, would have interfered with the study results or increased the risk of adverse effects,
3: were of any skin type or race providing the skin pigmentation would allow discernment of erythema,
4: had completed a medical screening procedure, and
5: had read, understood and signed an informed consent agreement.
Exclusion criteria:
Individuals excluded form participation in the study were those who:
1: had any visible skin disease at the study site which, in the opinion if the investigative personnel, would have interfered with the evaluation
2: were receiving systemic or topical drugs or medication which, in the opinion if the investigative personnel, would have interfered with the study results
3: had psoriasis and/or active atopic dermatitis/eczema
4: were females who were pregnant, planning to become pregnant during the study, or breast-feeding, and/or,
5: had a known sensitivity to cosmetics fragrances, skin care products or topical drugs as related to products being evaluated. - Controls:
- None
- Route of administration:
- dermal
- Details on study design:
- TYPE OF TEST(S) USED: patch test (epicutaneous test)
ADMINISTRATION
- Type of application: occlusive
- Description of patch: molded plastic chamber patch (25 mm Hilltop Chamber) lined with a non-woven cotton pad. The patch was secured with hypoallergenic tape (Micropore), as needed.
- Vehicle / solvent: DEP/ethanol (75/25)
- Concentrations: 5%
- Volume applied:0.3 mL
- Testing / scoring schedule:
Induction phase: Patches were applied three (3) times per week (Monday, Wednesday, and Friday) for a total of nine (9) applications. After 24 h patches were removed. Sites were evaluated 48 h to 72 h post application for irritation scores.
Challenge phase: Approximately two weeks after the final induction patch application, a challenge patch was applied to a virgin test site, following the same procedure described for induction. The patch was removed after 24 hours and the site scored 48 h and 72 h post-application.

Applicant's summary and conclusion
- Conclusions:
- Under the condition of the study, the test material is not a skin sensitiser at 5% in diethyl phtalate/ethanol (75%/25%).
- Executive summary:
A panel of 105 male and female human volunteers completed a repeat insult patch test in which a 5% solution of test material in 75% Diethyl phthalate / 25% Ethanol was applied to the back of the subjects under occlusive patches. During the induction phase nine patch were applied, separated by a 48-hour interval. The patches were removed 24 hours after application. Following a 2 -week rest period, a challenge patch was applied and the sites scored 48 and 72 hours after application.
Under the conditions employed in this study, there was no evidence of sensitisation to the test material at 5%.
