A new study published in Skin Research and Technology proposed a breast protector composite development using materials with tissue repair and moisturizing properties, aligned with a low-cost procedure, with the objective to heal nipple fissures and relieve pain in breastfeeding women, and assessed its physical and chemical properties, as well as its biocompatibility. Here, natural latex extracted from the rubber tree and glycerol were used as dressings. Physical and chemical assays disclosed that the matrix with glycerol possessed high pore density. The natural latex and glycerol did not interact covalently, indicating that the composite could release glycerol. Glycerol addition made the matrix more elastic, but fragile and increased its wettability. Both materials showed no hemolytic effects. In addition, glycerol did not exhibit cytotoxicity in fibroblasts, but showed a dose-dependent influence on keratinocytes. Thus, it was concluded that the breast protector composite devised for application over breast fissures has mechanical properties similar to those found in materials for dermal applications, and presents high wettability and pore density. Furthermore, the material showed no cytolytic activity and demonstrated biocompatibility.
