1. A laundry detergent sheet, comprising:
a) 5-35 wt. % of a bio-based polymer matrix, said bio-based polymer matrix configured in the form of a water-soluble sheet;
b) detergent components including a surfactant system comprising:
i) 0.1-30 wt. % of a neutrally charged surfactant; and
ii) 1-15 wt. % of an anionic surfactant, said neutrally charged surfactant and anionic surfactant each comprising non-petroleum derived carbons; and
c) a water-soluble, shear-stabilizing polymer comprising poly(2-ethyl-2-oxazoline), said poly(2-ethyl-2-oxazoline) incorporated in the bio-based polymer matrix; wherein the bio-based polymer matrix is configured to bind and suspend the detergent components when the bio-based polymer matrix is in solid sheet form and to release the detergent components when the bio-based polymer matrix contacts a sufficient volume of water; and wherein the laundry detergent sheet contains no detectable amount of polyvinyl alcohol.
