Background/purpose: The skin possesses buffering capacity to resist acidic/alkaline aggression. Skin components contribute differently to this buffering capacity. This study investigates buffering capacity in three skin layers: intact stratum corneum (SC), epidermis and dermis.
Methods: Sodium hydroxide (NaOH) and hydrochloric acid (HCl) solutions at 0.025, 0.05 and 0.1 N were applied to skin (3.18 μL/cm2). After 30 min, the skin was washed with 1 mL de-ionized water. TEWL and pH measurements were conducted at baseline (before contact with acid or base), 0, 10 and 30 min post exposure, and continued at 0, 10 and ...
