Hydrolyzed Oyster Shell Extract is a unique ingredient derived from the shells of oysters. Known by other names such as Oyster Shell Hydrolysate, this ingredient is primarily composed of calcium carbonate, along with trace minerals and amino acids. The process of hydrolysis, which involves breaking down the oyster shells using acid, enzymes, or other methods, transforms the raw material into a more bioavailable form suitable for cosmetic formulations.
Historically, oyster shells have been utilized for their mineral content in various industries, including agriculture and dietary supplements. However, it wasn’t until more recent advancements in cosmetic science that the potential skin benefits of Hydrolyzed Oyster Shell Extract were fully realized. Researchers discovered that the extract could be used to condition the skin, leading to its incorporation into a variety of skincare products.
The production of Hydrolyzed Oyster Shell Extract begins with the collection of oyster shells, which are then cleaned and ground into a fine powder. This powder undergoes hydrolysis, a process that breaks down the larger molecules into smaller, more manageable components. The resulting hydrolysate is then filtered and purified, ensuring that it is safe and effective for use in cosmetic products. This meticulous process ensures that the final extract retains its beneficial properties, making it a valuable addition to skincare formulations.
