Abstract

An enzymatically produced α-glucan oligomer/polymer compositions is provided. The enzymatically produced α-glucan oligomer/polymers can be derivatized into α-glucan ether compounds. The α-glucan oligomers/polymers and the corresponding α-glucan ethers are cellulose and/or protease resistant, making them suitable for use in fabric care and laundry care applications. Methods for the production and use of the present compositions are also provided.
