Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 272 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2017-03-27
• Study Completion Date: 2017-05-19

Brief Summary

The objective of this clinical study is to assess the irritation and sensitisation potential of a cosmetic test product after repeated semi-occlusive patch applications to healthy human participants by following a conventional HRIPT methodology under supervision of a dermatologist.

Detailed Description

The first phase of the study is an Induction Phase; a known amount of each product (test and control) is applied, under a semi-occlusive patch. Patches will remain on the skin for 48 (±2) (weekdays) or 72 (±2) (including inclusive weekends) hours during this phase. Induction phase lasts for 3 weeks. After the Induction Phase participants will enter a Rest Phase of 2 weeks duration, during which no patches are applied. After the Rest Phase, participants will return to the clinical site for the Challenge Phase. In this phase a challenge patch containing the test and control products is applied to virgin skin for 48 (±2) hours then assessed 30 minutes (maximum 1 hour) following removal, 24 (± 2) and 48 (±2) hours later.

Group Type: OTHER

Saline Solution: Sodium Chloride (NaCl; 0.9%)

Intervention Type: OTHER

Participant will have each product applied topically via semi occlusive patch, on site by the technician. Each patch will remain in place for 48 (± 2) hours on weekdays and 72 (± 2) hours on weekends.
