Abstract

Abstract A fabric treatment composition contains at least a detergent active material, a fabric softening agent and 0.5 to 3% a nonionic substituted cellulose ether derivative which has an HLB of 3.1 to 4.3 and a gel point of less than 58°C, which improve softening performances on cotton while controlling deposition on synthetic fabrics. Ethyl, hydroxyethyl or methyl hydroxyethyl cellulose ethers are preferred. The detergent active material is anionic or a mixture thereof with other detergent active materials and may be present at 2 to 50% of the composition. The softening agent may be soap, a cationic material, a fatty amine and/or a clay with a soap/cationic mixture being preferred, and may be present at 0.5 to 50% of the composition.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 81 words
A fabric treatment composition comprising ( i) a non-soap anionic detergent active material or a mixture thereof with other non-soap detergent active materials; ( ii) a fabric softening agent; and (iii) from 0.5 to 3% by weight of a nonionic substituted cellulose ether derivative having an HLB (as herein defined) of between 3.1 and 3.8, and a gel point (as herein defined) of less than 58°C provided that the derivative contains substantially no hydroxyalkyl groups containing 4 or more carbon atoms.
Claim 2
Dependent Claim 81 words
A fabric treatment composition comprising ( i) a non-soap anionic detergent active material or a mixture thereof with other non-soap detergent active materials; ( ii) a fabric softening agent; and (iii) from 0.5 to 3% by weight of a nonionic substituted cellulose ether derivative having an HLB (as herein defined) of between 3.1 and 3.8, and a gel point (as herein defined) of less than 58°C provided that the derivative contains substantially no hydroxyalkyl groups containing 4 or more carbon atoms.
