Composition and method of producing personal care compositions with improved deposition properties

A composition for conditioning a functional system substrate comprising an aqueous solution, comprising:

• a. at least one surfactant comprising a surfactant selected from the group consisting of a multi-tail surfactant, a sulfate-free surfactant, and combinations thereof;
• b. at least one functional system active ingredient;
• and
• c. a nonionic hydrophobically modified cellulose ether having a weight average molecular weight of from 100,000 to 2,000,000, and is hydrophobically substituted,
• wherein the amount of the hydrophobic substitution of the nonionic hydrophobically modified cellulose ether is in a range from a lower limit of 0.8 weight percent to an upper limit rendering the nonionic hydrophobically modified cellulose ether soluble in a five weight percent solution of surfactant, and at least one of (1) less than 0.5 percent by weight soluble in water, and (2) less than 0.05 percent by weight soluble in a one percent surfactant solution,
• wherein upon diluting the aqueous solution with water, the aqueous solution undergoes syneresis, whereby the nonionic hydrophobically modified cellulose ether separates from the aqueous solution and deposits upon the functional system substrate.
