The process of transforming rendered animal fat into a light, airy, and usable balm involves a technique similar to creating whipped cream. The objective is to incorporate air into the solidified fat, resulting in a softer consistency suitable for various applications. For example, tallow, typically hard at room temperature, can be rendered spreadable and more readily absorbed by the skin through this manipulation.
This method increases the surface area of the substance, making it easier to apply and allowing for enhanced absorption of any added ingredients. Historically, rendered animal fats have been utilized for their moisturizing properties and compatibility with human skin. Transforming it through aeration further improves its aesthetic appeal and user experience, thereby expanding its usability in cosmetic and therapeutic formulations.
