Technical parameters – EWALAN 30-PA
EWALAN 30-PA is a technologically advanced, pharmaceutical-grade anhydrous wool wax with a unique lipid profile rich in high-molecular-weight esters, aliphatic alcohols and sterols. In modern dermocosmetic and pharmaceutical formulations, it functions as a biomimetic penetration enhancer and a highly effective water-in-oil (W/O) emulsifier. Its performance is based on the physicochemical reduction of interfacial tension, which supports the rapid binding of the aqueous phase during mass homogenisation.
Thanks to rigorous refining and its “Extra Pale” classification, with a Gardner colour value of 6–8, the material helps eliminate aesthetic compromises in formulation development. It enables the creation of a snow-white, stable and visually uniform mass. After application to the skin, EWALAN 30-PA forms a plastic, biomimetic occlusive layer that mimics the natural epidermal barrier. These properties are directly linked to its physical parameters: a melting point of 38–44°C and a documented, enhanced water absorption capacity of at least 30 mL. Together, these characteristics significantly reduce the risk of syneresis, or phase separation, and may help shorten processing time in production environments.
EWALAN 30-PA undergoes a specialised thermal deodorisation process, resulting in a very low, almost imperceptible odour profile. The use of this lanolin grade can therefore reduce or eliminate the need for fragrance compositions used solely to mask the base odour. In addition, the strict control of pesticide residues, with a total limit of max. 1.0 ppm, including organochlorine pesticides below 0.05 ppm, together with the minimisation of free wool alcohols, significantly reduces the irritation potential and supports an optimised safety profile of the finished product. Its high oxidative stability, expressed by a peroxide value of max. 10 meq O₂/kg, also helps protect sensitive active pharmaceutical ingredients (APIs) incorporated into the system against premature degradation throughout the product’s shelf life.
