  • 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.

  • Patent number: 9751918
    Abstract: The present invention relates to the use of transgenic plants for the expression of vitamin B12 (cobalamin) binding proteins. Plant cells are transformed with nucleotide sequences adapted for expression and secretion of vitamin B12 binding proteins. The present invention also relates to the use of recombinant vitamin B12 binding proteins from plants in analytical tests and treatment of vitamin B12 deficiency. Also disclosed is a method for purification of recombinant vitamin B12 binding proteins.

  • Patent number: 9523014
    Abstract: The invention relates to a process for grinding cellulose ether comprising the steps of: a) grinding a cellulose ether comprising 20 to 90 wt % of water, based on the total weight of cellulose ether and water, and a cationic surfactant in a mill; and b) optionally drying the mixture while grinding, prior to or following the step of grinding.
