Assessment of diaper-clogging potential of petrolatum moisture barriers

Petrolatum-based ointments often are used to treat and prevent incontinence dermatitis. However, anecdotal reports indicate that petrolatum ointments may affect the absorbency of disposable briefs also commonly used in incontinence management. To examine whether petrolatum ointments clog a commonly used absorbent brief, a randomized, balanced-block design study was conducted in a controlled laboratory setting to compare the brief-clogging potential of three petrolatum ointments to a non-alcohol barrier film. Test products were applied to 6-cm x 6-cm test sites on the volar forearms of 16 volunteers. Pre-weighed mini briefs were applied to the test sites in a manner that simulates normal brief wear. After 5 minutes of wear, the mini briefs were weighed to determine percent of product transfer from skin to mini brief. The mini briefs then were reapplied to the same test sites and a synthetic urine solution was introduced between the skin and the mini brief. Mini briefs subsequently were removed to determine fluid uptake by weight. Results indicate significant differences between the four test products (P < 0.01) both in percent transfer and in mini brief fluid absorption. From 59% to 69% of the petrolatum-based products transferred from the skin to the mini briefs and a 54% to 90% reduction in fluid uptake was noted, as determined by weight. The non-alcohol barrier film did not transfer to the mini brief and fluid uptake was minimally affected. Further study in the clinical and practice settings to determine the effect and consequences of barrier product transfer on absorbent garments is warranted.
