Abstract
A dissolvable sheet having a water-soluble substrate, and one or more cleaning actives disposed uniformly throughout the water-soluble substrate. The water-soluble substrate is formed from a first substrate builder comprising polyvinyl alcohol, a second substrate builder, such as starch, and sodium laurylglucosides hydroxypropylsulfonate, and is sized and shaped to form a sheet, and hold a premeasured amount of the cleaning active. The substrate dissolves when contacted with a sufficient amount of water, thereby releasing the cleaning active into the water, which also dissolves in the water. A method of making the dissolvable sheet is also disclosed.
