Abstract: A zeolite powder of the Na A type has an average particle size (50% point) of 1.6-3.2 microns, measured with the Cilas 715 granulometer. USE/ADVANTAGE - A liq. washing compsn. contg. the zeolite powder is claimed. The zeolite is a substit. for phosphate. The liq. washing compsn. has a satisfactory viscosity. In an example, (A) Aq. compsns. contg. 13% of Na alkylbenzene sulphonate as anionic detergent, and 7% of a 13-15C oxo alcohol ethoxylate (7 EO), and 15%, 25% or 35% of zeolite NaA of varying particle size, were tested for viscosity at 5 rpm; (B) In a storage stability test, using suspensions with 15%, 25% or 35% of zeolite NaA, max. stability was obtd. with a zeolite of particle size 1.8 microns, esp. with 25% of zeolite.
