Abstract
The invention relates to aqueous benzisothiazoline-3-one dispersions of sodium-1,2-benzisothiazoline-3-one particles dispersed in water. The dispersions contain: (a) between 15 wt.-% and 35 wt.-% of sodium-1,2-benzisothiazoline-3-one; and (b) ad. 100 wt.-% of water having a content of sodium ion in the range from 4 wt.-% to 10 wt.-% with respect to water contained in the dispersion. The invention further relates to the use of the claimed dispersions for preserving water-based products of all types, in particular, cleaning and household products, plastics dispersions, paints, plasters, adhesives, sealing compounds, paper coating materials, textile softeners and sizing agents, washing raw materials, surfactants, polishing agents, spinning baths, cooling lubricants, leather treatment agents and silicone and bitumen emulsions.
