Abstract

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

First claim

The invention claimed is:

1. A laundry or dishwashing composition, comprising:
a tertiary amine substituted cellulose derivative having Formula I:

wherein n is an integer sufficient to produce a polymer with a weight-average molecular weight (Mw) in the range of about 50,000 to 2,000,000;
R 1 is, independently at each occurrence, H, —CH 3 , or —CH 2 CH 2 O—R 2 ; and
R 2 is, independently at each occurrence, H, CH 3 , or R 3 N(R 4 ) 2 or it salt wherein:
R 3 is C 1-6 alkylene;
R 4 is, independently at each occurrence, C 1-6 alkyl, or both R 4 groups may form, along with the nitrogen to which they are attached, a saturated or unsaturated 5 or 6 member heterocyclic ring,

provided that at least one R 1 in the polymer contains an R 3 N(R 4 ) 2 group; and
at least one surfactant; and
a builder,

wherein the R 3 N(R 4 ) 2 group is not a permanently charged quaternary amine, and wherein the tertiary amine substituted cellulose derivative of formula I has a tertiary amine degree of substitution, DS amine , of the R 3 N(R 4 ) 2 groups per molecule of 0.1 to 0.4.

2. The laundry or dishwashing composition of claim 1 , wherein R 3 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:

wherein n is an integer sufficient to produce a polymer with a weight-average molecular weight (Mw) in the range of about 50,000 to 2,000,000;
wherein R 1 is, independently at each occurrence, H, —CH 3 , or —CH 2 CH 2 O—R 2 ; and
wherein R 2 is, independently at each occurrence, H, CH 3 , or R 3 N(R 4 ) 2 or it salt, wherein R 3 is C 1-6 alkylene; wherein R 4 is, independently at each occurrence, C 1-6 alkyl, or both R 4 groups may form, along with the nitrogen to which they are attached, a saturated or unsaturated 5 or 6 member heterocyclic ring;

wherein the tertiary amine substituted cellulose derivative of formula I is a tertiary amine substituted hydroxyethylcellulose having an overall degree of substitution, DS overall , of 1.17 to 1.18; and, wherein the tertiary amine substituted cellulose derivative of formula I has a tertiary amine degree of substitution, DS amine , of non-permanently charged tertiary amine R 3 N(R 4 ) 2 groups per molecule of 0.1 to 0.4.

8. The laundry or dishwashing composition of claim 7 , wherein R 3 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.
