Abstract: The present invention relates to a substantially anhydrous suspension incorporating at least one biostable hydroxyalkylcellulose having an MS of 1.0 to 3.0, at least one oil, and at least one defoamer. The cellulose ether is preferably a hydroxyethylcellulose (HEC) having an MS of 1.0 to 3.0, preferably of 1.8 to 2.8, more preferably about 2.4. The oil is preferably a natural oil. Further disclosed is an emulsion paint, more particularly for interior coatings, which includes this suspension. It is particularly resistant to enzymes having a cellulytic action (cellulases), and this is manifested in a reduced fall in viscosity.

Abstract: The invention relates to mixtures of cellulose ethers, comprising A) allyl-modified cellulose ethers of formula (1) where C6H7O2 is one anhydroglucose unit, n is from 50 to 1600, R1, R2 and R3 independently of one another are a polyalkylene oxide chain of the formula (2), with X=H, CH3, C2H5 or CH2CH?CH2 and in which p, q and r independently of one another, in R1, R2 and R3 each independently, can adopt values from 0 to 4, the sum (p+q+r) added over R1, R2 and R3 per anhydroglucose unit is on average more than 1.3 and less than 4.5, the sequence of the oxyalkyl units in the polyalkylene oxide chain is arbitrary and the average number of —CH2CH?CH2— groups per anhydroglucose unit is from 0.01 to 0.
