Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
123 words
A concentrated homogeneous liquid detergent composition containing: (a) from 10% to 50% by weight of a mixture of anionic synthetic and nonionic surface-active agents; (b) less than 50% by weight of water; (c) from 2% to 50% by weight of a water-soluble monoester of a dicarboxylic acid selected from the group consisting of dodecanol succinate, tridecanol phthalate, tetradecanol phthalate, pentadecanol phthalate, hexadecanol phthalate, heptadecanol phthalate, and octadecanol phthalate, (d) the non-ionic surface-active agent is present at a level of at least 5% by weight of the total composition; and (e) said composition has a pH, in a 1% solution in water at 20° C., in the range of from 6 to 9 and said composition is free of cumene and xylene sulfonate hydrotropes.
