Abstract

Abstract A liquid detergent composition comprising 0.5 to 30% by weight of at least one alkanolamine represented by the following general formula (1): (C.sub.n H.sub.2n OH).sub.m NH.sub.3-m (1) wherein n is an integer of from 1 to 3 and m is an integer of from 1 to 3, 0.5 to 30% by weight of a polyoxyalkylene mono- or di-lower alkyl ether represented by the following general formula (2): RO(C.sub.2 H.sub.4 O).sub.x (C.sub.3 H.sub.6 O).sub.y R' (2) wherein R and R' stand for a hydrogen atom, a methyl group or an ethyl group, with the proviso that the case where both of R and R' are hydrogen atoms is excluded, the mean value of (x+y) is from 3.0 to 10.0 and the relation of 0.0≦×≦0.25y is established, and 0.1 to 20% by weight of at least one surface active agent.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 136 words
A liquid detergent composition consisting essentially of: 0.5 to 30% by weight of one or a mixture of two or more alkanolamines having the formula (C.sub.n H.sub.2n OH).sub.m NH.sub.3-m wherein n is an integer of from 1 to 3 and m is an integer of from 1 to 3; 0.5 to 30% by weight of one or a mixture of two or more polyoxyalkylene mono- or di-lower alkyl ethers having the formula RO(C.sub.2 H.sub.4 O).sub.x (C.sub.3 H.sub.6 O).sub.y R' wherein R and R' are hydrogen, methyl or ethyl, with the proviso that both of R and R' are not hydrogen simultaneously, the mean value of x plus y is from 3.0 to 10.0 and 0.0≦x≦0.25y; 0.1 to 20% by weight of one or a mixture of water-soluble, synthetic, organic surfactants; and the balance is essentially water.
Claim 2
Dependent Claim 136 words
A liquid detergent composition consisting essentially of: 0.5 to 30% by weight of one or a mixture of two or more alkanolamines having the formula (C.sub.n H.sub.2n OH).sub.m NH.sub.3-m wherein n is an integer of from 1 to 3 and m is an integer of from 1 to 3; 0.5 to 30% by weight of one or a mixture of two or more polyoxyalkylene mono- or di-lower alkyl ethers having the formula RO(C.sub.2 H.sub.4 O).sub.x (C.sub.3 H.sub.6 O).sub.y R' wherein R and R' are hydrogen, methyl or ethyl, with the proviso that both of R and R' are not hydrogen simultaneously, the mean value of x plus y is from 3.0 to 10.0 and 0.0≦x≦0.25y; 0.1 to 20% by weight of one or a mixture of water-soluble, synthetic, organic surfactants; and the balance is essentially water.
Claim 3
Dependent Claim 23 words
