Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
112 words
A hard surface liquid cleaner composition consisting essentially of: (a) from about 0.1% to about 10% of a nonsoap surfactant selected from the group consisting of: anionic, cationic, nonionic, zwitterionic, amphoteric surfactants and mixtures thereof; (b) from about 0.5% to about 25% of a diol selected from the group consisting of C 6 -C 12 diols and mixtures thereof; wherein at least one hydroxy group of said diol is a primary or secondary hydroxy group and wherein said diol has a maximum solubility of about 12 g/100 g of water at 20° C.; (c) from about 1% to about 30% of a detergency builder salt; and (d) at least about 60% water.
