Usp grade

Example 4

A common wart (verruca) on the cheek of a 56 year old white male (Fitzpatrick Type 2 skin) was treated with a solution comprising 40% hydrogen peroxide (FMC/PeroxiChem “Super D”), and 5% 2-propanol (Spectrum Chemical USP Grade). After cleansing of the skin with 70% 2-propanol, the solution was applied topically to the seborrheic keratosis lesion using a flocked doe-foot shaped applicator. Using firm pressure and an application technique that was appropriate for the target lesion size, the solution was applied for approximately 20-30 seconds. After approximately 1-2 minutes, the application process was repeated. This sequence was repeated until 4 applications had been performed. There was no pain or discomfort during the procedure. Over the next several days the lesion evidenced superficial crusting and mild erythema (redness). Follow-up 2 weeks after the treatment revealed the verruca to be completely resolved with no erythema and no evidence of scarring or pigmentary change (hyperpigmentation or hypopigmentation). Follow-up 8 weeks after the treatment revealed no recurrence of the lesion and no adverse cosmetic sequelae. The subject was extremely pleased with the results.
