Spent Grain Wax
What is Spent Grain Wax?
Spent Grain Wax is a plant-based wax sourced from the lipid-rich fraction of barley spent grain, a byproduct of the beer brewing process involving Hordeum vulgare. Composed primarily of long-chain fatty acids, esters, and alcohols, it serves as an emollient in cosmetics. Typically incorporated into anhydrous products such as lip balms, solid sticks, and protective ointments, it forms a protective barrier on the skin while delivering occlusive benefits. As a multifunctional ingredient, it enhances product texture by increasing viscosity, preventing separation, and improving application ease. Its sustainable origin from brewery waste appeals to green formulations, supporting smooth, flexible skin feel without greasiness.
