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.

Time frame: At Day 3
A trained assessor assessed all patch sites. The following scores were used to express the response observed at the time of examination: 0=No evidence of irritation, 1=Minimal erythema; barely perceptible, 2=Definite erythema, readily visible; or minimal edema; or minimal papular response, 3=Erythema and papules, 4=Definite edema, 5=Erythema, edema, and papules, 6=Vesicular eruption, 7=Strong reaction spreading beyond test site. Other features indicative irritation (Superficial irritation) scores were: Grade A/Score 0=Slight glazed appearance, Grade B/Score 1=Marked glazing, Grade C/Score 2=Glazing with peeling and cracking, Grade F/Score 3=Glazing with fissures, Grade G/Score 3=Film of dried serous exudate covering all or portion of the patch, Grade H/Score 3=Small petechial erosions and/or scabs. Superficial irritation scores were only provided if there was a dermal response score >0. Full range was 0-10. Lower score indicates better tolerability.
