Claims
- 1. A stabilized aqueous, built, clear single-phase, enzyme-containing liquid detergent composition comprising:
- (a) from about 8 to 20%, by weight, of one or more surface active anionic detergent compounds;
- (b) from about 5 to 25%, by weight, of a water-soluble non-phosphate detergent builder salt;
- (c) an effective amount of an enzyme or enzyme mixture selected from the group consisting of alkaline protease enzymes and alpha-amylase enzymes;
- (d) an enzyme stabilizing system containing, based on the weight of the detergent composition, (i) from about 12 to 25% of propylene glycol and (ii) from about 1 to 5% of a boron compound selected from the group consisting of boric acid, boric oxide and alkali metal borates; and
- (e) from about 25 to 75%, by weight, water, said liquid detergent composition being substantially free of cross-linked polyacrylates polymers.
- 2. A detergent composition according to claim 1 wherein said builder salt is sodium citrate.
- 3. A detergent composition according to claim 1 wherein said builder salt is sodium nitrilotriacetate.
- 4. A detergent composition according to claim 1 which is substantially free of a phosphate detergent builder salt.
- 5. A detergent composition according to claim 1 which contains from about 15 to 20%, by weight, of propylene glycol and from about 1 to 3%, by weight, of said boron compound.
- 6. A detergent composition in accordance with claim 1 wherein said boron compound is borax.
- 7. A detergent composition in accordance with claim 1 wherein said builder salt is present in an amount of from about 10 to 20%, by weight.
- 8. A detergent composition according to claim 1 wherein the anionic detergent is a mixture of a C.sub.10 -C.sub.18 alkyl benezene sulfonate salt and a polyethoxylated C.sub.10 -C.sub.18 alcohol sulfate salt.
- 9. A method of laundering comprising contacting the stained and/or soiled fabrics to be laundered with an enzyme-containing, built, clear single-phase liquid detergent composition comprising;
- (a) from about 8 to 20%, by weight, of one or more surface active anionic detergent compounds;
- (b) from about 5 to 25%, by weight, of a water-soluble non-phosphate detergent builder salt;
- (c) an effective amount of an enzyme or enzyme mixture selected from the group consisting of alkaline protease enzymes and alpha-amylase enzymes;
- (d) an enzyme stabilizing system containing, based on the weight of the detergent composition, (i) from about 12 to 25% of propylene glycol and (ii) from about 1 to 5% of a boron compound selected from the group consisting of boric acid, boric oxide and alkali metal borates; and
- (e) from about 25 to 75%, by weight, water, said liquid detergent composition being substantially free of cross-linked polyacrylate polymers.
- 10. A method according to claim 9 wherein said builder salt is sodium citrate.
- 11. A method according to claim 9 wherein said builder salt is sodium nitrilotriacetate.
- 12. A method according to claim 9 wherein said detergent composition is substantially free of a phosphate detergent builder salt.
- 13. A method according to claim 9 wherein said detergent composition contains from about 15 to 20%, by weight, of propylene glycol and from about 1 to 3%, by weight, of borax.
- 14. A method according to claim 9 wherein said detergent composition contains from about 10 to 20% of a non-phosphate builder set.
- 15. A method according to claim 9 wherein said detergent composition contains a mixture of a C.sub.10 -C.sub.18 alkyl benzene sulfonate salt and a polyethoxylated C.sub.10 -C.sub.18 alcohol sulfate salt.
