Abstract
The emollient-transfer and frictional effects of a new, emollient-treated menstrual pad were studied to examine potential skin moisturization. When pads were applied for 6 hours to the popliteal fossa (behind-the knee [BTK] test), 79 μg of emollient per cm2 was transferred from the pad surface. When swiped across forearm skin in a controlled fashion, the emollient-treated pads, but not the conventional pads, caused a rise in the coefficient of skin friction, indirect evidence of skin moisturization. When irritant and sensory effects were assessed in the BTK protocol, the test pad was comparable with the commercial product currently considered to be “best-in-class” for softness.
