Detergent composition |
(57) A chlorine bleach-free aqueous liquid machine dishwashing composition having solution
pH 7-11 contains proteolytic enzyme, detergency builder, sodium silicate having SiO₂:Na₂O
ratio of from 2.0-3.2 and organic surfactant which comprises (i) glycoside surfactant,
(ii) anionic sulphate or sulphonate including a C₈ to C₂₂ alkyl or alkenyl group or
(iii) ethoxylated C₆ to C₁₆ fatty alcohol with HLB of at least 10.5, or a mixture
of (i), (ii) and/or (iii). If (iii) is used without (ii) it must be an ethoxylated
C₆ to C₁₂ alcohol, or glycoside surfactant must also be present. Proteolytic enzyme
plus the specified surfactant gives a synergistic improvement in removal of proteinaceous
soil.
