  • Methyl-ethyl-hydroxyalkyl-cellulose and its use in building compositions
    Patent number: 11834522
    Abstract: A methyl ethyl hydroxyalkyl cellulose (MEHEC), process for making the MEHEC, and a powder containing the MEHEC are disclosed. The MEHEC is provided with a DSmethyl from 1.5 to 2.5, a DSethyl from 0.005 to 0.15, and a MSalkylene-oxide from 0.005 to 0.2. The methyl ethyl hydroxyalkyl cellulose optionally includes an anti-oxidant. The MEHEC optionally does not have a combination of a DSmethyl of 2.2 or 1.8, a DSethyl of 0.05 or 0.1, and a MSalkylene-oxide of 0.1 and does not have a combination of a DSmethyl of 2.5 or 2.0, a DSethyl of 0.1, and a MSalkylene-oxide of 0.05. The MEHEC has very good biostability and is suitable for use in the building industry.
