A Natural Cream-to-Powder Formulation Developed for the Prevention of Diaper Dermatitis in Diaper-Wearing Infants and Children: Barrier Property and In-Use Tolerance Studies.
INTRODUCTION: Diaper dermatitis is a common condition that develops in the diaper area due to factors such as elevated moisture, increased skin surface pH, and exposure to irritants from urine and feces. These factors suggest interventions to prevent or treat diaper dermatitis such as exposing the skin to air, frequent diaper changes, and thorough cleansing of the diaper area. Barrier creams and powders also have a role in preventing and treating diaper dermatitis. We developed a cream-to-powder product with a formula based on corn starch and other natural ingredients for use in the diaper area. METHODS: Dye exclusion study: The barrier properties of the cream-to-powder product were assessed using a dye exclusion protocol. Skin color at treated and untreated forearm sites was measured at baseline and after exposure to crystal violet stain. The cream-to-powder product's ability to inhibit the water-soluble dye from reaching the skin was judged by comparing color changes at the treated and untreated sites. Tolerance-in-use study: The safety of the cream-to-powder product was assessed in a four-week tolerance-in-use study conducted in a group of 52 diaper-wearing infants and toddlers. Subjects' parents/guardians applied the cream-to-powder product at each diaper change. A pediatrician judged safety endpoints of erythema, dryness, and edema in the diaper area at baseline and at study end. Parents/guardians also completed a questionnaire at study end. These studies have complied with Good Clinical Practices (GCP/ICH). OUTCOMES: The cream-to-powder product prevented about 70% of the test dye from reaching the skin surface, demonstrating its ability to supplement the skin barrier. The tolerance-in-use study showed no statistically significant changes in any of the safety endpoints; there were no adverse events. Parents/guardians responses to the cream-to-powder product were overwhelmingly positive. Taken together, these results support that the cream-to-powder formulation is safe and effective for helping to prevent diaper dermatitis. J Drugs Dermatol. 2018;17(5):566-570.
