Abstract
Abstract Stable concentrated aqueous liquid soap solutions containing up to 50%, and possibly higher, by weight of sodium soap can be obtained, if the soap comprises a mixture of at least one sodium soap (A) derived from C 8 -C 14 saturated fatty acids and at least one sodium soap (B) derived from C 16 -C 22 mono- and/or di-unsaturated fatty acids, in which the ratio by weight of soap (A) to soap (B) is within the range of 9:1 to 1:9.

Claim 1
Independent Claim
81 words
An aqueous liquid sodium soap solution containing from 20% to 45% by weight of a sodium soap consisting essentially of a mixture of (A) at least one sodium soap of C 8 -C 14 saturated fatty acid and (B) at least one sodium soap of fatty acids selected from the group consisting essentially of C 16 -C 22 mono and C 16 -C 22 di-unsaturated fatty acids and mixtures thereof, the ratio of A to B being from 4:1 to 1:4.
Claim 2
Dependent Claim
81 words
An aqueous liquid sodium soap solution containing from 20% to 45% by weight of a sodium soap consisting essentially of a mixture of (A) at least one sodium soap of C 8 -C 14 saturated fatty acid and (B) at least one sodium soap of fatty acids selected from the group consisting essentially of C 16 -C 22 mono and C 16 -C 22 di-unsaturated fatty acids and mixtures thereof, the ratio of A to B being from 4:1 to 1:4.
Claim 3
Dependent Claim
69 words
An aqueous liquid soap solution according to claim 1 in which soap (A) is derived from C 8 -C 14 saturated fatty acids having a proportion of C 8 -C 12 fatty acids of more than 50% by weight, and soap (B) is derived from C 16 -C 22 mono- and/or di-unsaturated fatty acids having a proportion of C 18 -mono-unsaturated fatty acids of more than 50% by weight.
