The present invention provides a package for a phase stable, liquid nonaqueous detergent, comprising: a plastic, relatively thin-walled container, said container having an end wall and a circumscribing side wall which narrows to a finish, and a liquid detergent contained in said container, said detergent comprising: (a) 20-90% of a liquid portion which comprises an alkoxylated nonionic surfactant; (b) 5-50% of a solids portion which comprises: (i) a builder; (ii) 0-20% of the detergent of an oxidant; said solids being stably suspended in said liquid portion, by means of (c) a phase stabilizing amount of a lower alkylated fused ring polyarylene sulfonate; and (d) 0-5% of a hydrolytic enzyme; whereby the phase stability of said liquid detergent in storage in said container is controlled, by the selection of either: (1) said container being constructed of a homopolymeric resin, said container having a minimum average cross-sectional dimension r/2 of at least about 6. 8 millimeters in order to minimize interaction with said plastic; (2) said container being constructed of a heteroatom-containing polymer; or (3) a combination thereof.

The invention provides a phase stable liquid detergent containing at least one particulate oxidant, comprising: a) a liquid phase which comprises: i) an effective amount of at least one surfactant selected from the group consisting of anionic, nonionic, cationic, amphoteric, zwitterionic surfactants, and mixtures thereof; ii) a liquid carrier therefore, comprising organic Solvents, water, or a mixture thereof; b) an effective amount of a particulate oxidant stably suspended in said liquid phase, which maintains oxidative stability, said oxidant being selected from the group consisting of alkali metal perborate and percarbonates; and c) an oxidant stabilizer selected from the group consisting of alkali metal chloride, alkali metal borate, boric acid and mixtures thereof.

A method and means for measuring erythrocyte deformability is provided comprising an absorbent strip and a filter membrane, the membrane characterized by pores having a mean pore size in the range of 3. 0 to 8. 0 microns, the membrane and the strip being in at least partial cofacial contact. A 10 microliter sample of blood is drawn through the membrane by capillary action and flows along the absorbent strip. The time required for the blood to traverse a predetermined lateral distance along the strip is recorded.

The present invention provides a stable liquid, substantially nonaqueous, detergent comprising, by weight percent: (a) 20-90% of a liquid portion which comprises an alkoxylated nonionic surfactant; (b) a solids portion which comprises: (i) 5-50% of a builder; (ii) 0-20% of an oxidant; said solids being stably suspended in said liquid portion, by means of (c) a phase stabilizing amount of a lower alkylated fused ring polyarylene sulfonate; and (d) 0-5% of a hydrolytic enzyme. Further desirable adjuncts may be added to the liquid compositions of this invention.

A method and device is provided for simply and rapidly measuring erythrocyte deformability by placing samples of blood on a set of porous membranes or a membrane strip with graded series of sharply defined pore sizes to determine the selective absorption thereon. Based on observation of the selective absorption on the membranes or membrane strip the deformability index of the erythrocytes may be determined.

An improved cleaning composition is provided for shower and tub surfaces which is of the "shower rinsing" type, requiring no scrubbing, wiping, or immediate rinsing. The composition comprises: (a) a glycoside surfactant, the total amount of said surfactant being present in a cleaning effective amount; (b) a chelating agent, said chelating agent present in an amount effective to enhance bathroom soil removal in said composition; and (c) the remainder, water. A solvent such as isopropyl alcohol may also be added. The employment of a glycoside surfactant, especially one having an HLB value of greater than 13, remarkably improves the performance of such a shower rinsing composition both with respect to surface appearance streaking and filming and also bathroom soil and soap scum removing ability.
