Irritation and Sensitization of Chlorhexidine Gluconate (CHG) Cloth


Evaluating the irritation properties of CHG cloth. Some Subjects will also have the product applied to see if they become sensitized to repeated applications.

Detailed Description

For the Irritation Study (30 subjects), patches containing CHG, vehicle, saline, CHG comparator or sodium lauryl sulfate (a product that is expected to produce a slight skin irritation) will be placed on the same spot of your skin every day for 21 days. The skin will be examined every day.

The Sensitization Study (200 total subjects) place patches containing CHG, vehicle, saline, CHG comparator on the skin 3 times a week for 3 weeks. Following a two-week rest period the patches will be reapplied for 48 hours and assessed out to 72 hours thereafter.

Clinical Trial Outcome Measures

Primary Measures

  • Grading Scale for Visual Evaluation of Skin Condition
    • Time Frame: 21 Days for Irritation (N=39). 35 Days for Sensitization (N=249)
    • Irritation: 21 days of patching (total). A reviewer will assign a score based on an 8 point categorical scale to the areas treated at each visit. Sensitization: 35 days (21 days of patching followed by 14 days rest and subsequent patch). A reviewer will assign a score based on an 8 point categorical scale to the areas treated at each visit. SLS was not tested. Grade 0 = No irritation Grade 1 = Minimal erythema Grade 2 = Definite erythema Grade 3 = Erythema and papules Grade 4 = Edema Grade 5 = Erythema, edema and papules Grade 6 = Vesicular eruption Grade 7 = Strong reaction spreading
