Abstract

Described are fabric and surface care compositions comprising a tertiary amine substituted cellulose derivative and at least one surfactant.

Claims

1. A laundry or dishwashing composition, comprising:

a tertiary amine substituted cellulose derivative having Formula I;

2. The laundry or dishwashing composition of claim 1, wherein R₃ at each occurrence is ethylene.

3. The laundry or dishwashing composition of claim 1, wherein the tertiary amine substituted cellulose derivative is at least one of N,N-diethylaminoethyl hydroxyethylcellulose, N,N-dimethylaminoethyl hydroxyethylcellulose, N,N-diisopropyl aminoethyl hydroxyethylcellulose, N,N-dimethylaminopropyl hydroxyethylcellulose, N-ethyl piperidine hydroxyethylcellulose, N-ethyl morpholine hydroxyethylcellulose, or N-ethyl pyrrolidine hydroxyethylcellulose.

4. The laundry or dishwashing composition of claim 1, wherein the surfactant is linear alkyl benzene sulfonate, sodium alcohol ethoxylate sulfate, a mixture of linear alkyl benzene sulfonate and sodium alcohol ethoxylate sulfate, a nonionic alcohol ethoxylate, or mixtures thereof.

5. The laundry or dishwashing composition of claim 1, further comprising one or more of an inorganic builder/chelant, soda ash, a bleach, and/or a bleach activator.

6. The laundry or dishwashing composition of claim 1 further comprising one or more of a polyethylene glycol, starch, or clay.

7. A laundry or dishwashing composition, comprising:

a builder;

at least one surfactant; and

a tertiary amine substituted cellulose derivative having Formula I;

8. The laundry or dishwashing composition of claim 7, wherein R₃ at each occurrence is ethylene.

9. The laundry or dishwashing composition of claim 7, wherein the tertiary amine substituted cellulose derivative is at least one of N,N-diethylaminoethyl hydroxyethylcellulose, N,N-dimethylaminoethyl hydroxyethylcellulose, N,N-diisopropylaminoethyl hydroxyethylcellulose, N,N-dimethylaminopropyl hydroxyethylcellulose, N-ethyl piperidine hydroxyethylcellulose, N-ethyl morpholine hydroxyethylcellulose and N-ethyl pyrrolidine hydroxyethyl cellulose.

10. The laundry or dishwashing composition of claim 7, wherein the surfactant is selected from the group consisting of a linear alkyl benzene sulfonate, a sodium alcohol ethoxylate sulfate, a nonionic alcohol ethoxylate, and mixtures thereof.

11. The laundry or dishwashing composition of claim 7, further comprising at least one of an inorganic builder/chelant, a soda ash, a bleach and a bleach activator.

12. The laundry or dishwashing composition of claim 7, further comprising at least one of a polyethylene glycol, a starch and a clay.
