Hydrolyzed Rice Ferment Lees, also known as Hydrolyzed Rice Ferment (Sake) Lees, is a unique ingredient derived from the by-products of sake production. Sake, a traditional Japanese alcoholic beverage made from fermented rice, leaves behind a residue known as sake lees. This residue is rich in nutrients and has been utilized in various applications, including cosmetics. The hydrolysate of Rice Ferment (Sake) Lees is obtained through hydrolysis, which can be achieved using acid, enzymes, or other methods to break down the complex molecules into simpler, more beneficial compounds.
Historically, sake lees have been used in Japan for centuries, not only in culinary practices but also in skincare routines. The geishas of ancient Japan were known to use sake lees to maintain their porcelain-like skin. Over time, the cosmetic industry recognized the potential of this ingredient and began incorporating it into modern skincare formulations.
The process of making Hydrolyzed Rice Ferment Lees involves collecting the sake lees and subjecting them to hydrolysis. This process breaks down the proteins, starches, and other components into smaller, more bioavailable molecules. The resulting hydrolysate is then filtered and purified to create a potent ingredient that can be easily absorbed by the skin. This ingredient is primarily used for its skin conditioning properties, helping to improve the texture and appearance of the skin.
