Abstract
Low cost, effective aqueous heavy duty liquid laundry detergent compositions are provided. Such compositions contain relatively low levels of an anionic/nonionic-based suffactant system along with a protease-containing enzyme component, a low-cost viscosity-enhancing agent and relativly large amounts of water. The anionic component of the surfactant system comprises a combination of alkyl sulfate and alkyl ether sulfate. The nonionic component of the suffactant system comprises fatty alcohol ethoxylates. Only minimal amounts of other detergent composition adjuvants are permitted in such compositions.
