1. A freshening composition comprising;
- a plurality of particles;
a polysaccharide system comprising at least two polysaccharides selected from the group consisting of xanthan gum, glucomannan, galactomannan, and combinations thereof, wherein the polysaccharide has an average ratio of acetylation of less than 2.0, wherein the total polysaccharide level of the composition is less than 0.1 wt. %, by weight of the composition;
an aqueous carrier,wherein the composition has a spray shear viscosity, as measured according to the YIELD STRESS AND SPRAY SHEAR VISCOSITY TEST METHOD described herein, of less than about 0.025 Pa-s,and wherein the composition has a creep recovery ratio of at least about 0.1, as measured according to the CREEP RECOVERY RATIO TEST METHOD described herein, or a yield stress of greater than 0 Pa and less than 1.0 Pa, as measured by the YIELD STRESS AND SPRAY SHEAR VISCOSITY TEST METHOD described herein.
