2. The composition according to claim 1 , wherein the microfibrous cellulose concentration is about 0.075%.
3. The composition according to claim 1 , wherein the particulate is selected from the group consisting of air bubbles, beads, and any combination thereof.
4. The composition of claim 1 , wherein the microfibrous cellulose is bacterially derived.
5. The composition of claim 1 , wherein the cationic surfactant system is transparent.
6. The composition of claim 1 , wherein the microfibrous cellulose is dispersed and not appreciably solubilized.
7. The composition of claim 1 , wherein the aqueous composition has a Yield Point selected from 1.4, 0.2, 0.36, and 4.5 Pa.
8. The composition of claim 1 , wherein the cationic surfactant system does not contain a co-agent.
9. Method of preparing an aqueous composition comprising a cationic surfactant system consisting essentially of:
combining microfibrous cellulose with water and mixing,
adding cationic surfactant and then mixing, and
adding a particulate followed by mixing,
wherein the resulting cationic surfactant system is clear and the particulates are suspended therein and wherein the microfibrous cellulose is present at a concentration between about 0.05% and about 0.09% (w/w) and the cationic surfactant is present at a concentration between about 40% and about 50% (w/w active surfactant).
10. The method of claim 9 , wherein the microfibrous cellulose concentration is between about 0.06% and about 0.075%.
