  • Applications

    alpha,beta-Trehalose (CAS 585-91-1) is widely used as a stabilizer and protective agent in pharmaceutical and biotech formulations, where it acts as a cryoprotectant and lyoprotectant to preserve proteins, enzymes, and vaccines during drying, freezing, and storage. In cosmetics and personal care, trehalose serves as a humectant and moisturizing ingredient that helps retain moisture and improve texture in products such as creams, lotions, and masks. In food processing, trehalose often acts as a stabilizer and mild sweetener that helps maintain moisture and texture in processed foods. In agriculture, it is sometimes evaluated for seed treatment and crop protection applications, where it may help plants withstand environmental stress. These applications are formulation-dependent and subject to local regulations and limits.
