Panalane® L-14E is a low viscosity grade hydrogenated polyisobutene. It is a versatile emollient ideal for a wide variety of personal care products. In clinical studies Panalane® L-14E was proven to increase skin hydration by reducing the rate of water evaporation from the skin’s surface, as measured by trans-epidermal water loss (TEWL). Retention of skin moisture content was also confirmed by increased skin conductance measurements.
