Description

Detailed Description of the Invention

[0001]

【Technical field】

The present invention relates to laundry detergent compositions containing one or more hydrophobically modified polyamines with improved hydrophilic soil, especially clay removal properties. The invention also relates to a method of removing hydrophilic soil from clothing.

[0002]

[Background technology]

Cloths, especially clothing, are hydrophobic stains (grease, oil) to hydrophilic stains (clay)
It becomes dirty with various foreign substances. The level of cleaning required to remove such foreign matter varies greatly depending on the amount of dirt present and the degree to which the foreign matter is in contact with the fabric fibers. Grass fouling is usually due to direct rubbing and contact with plant material, which results in extremely penetrating fouling. The stains of clay stains may come into contact with the fabric fibers with less force, but due to the high charge associated with the clay itself,
There are different types of problems with dirt removal. This high surface charge density has the effect of repelling certain laundry co-ingredients, especially clay dispersants, which significantly hinders peptization and disperses the clay in the laundry liquor.

Surfactants themselves are not all that are needed to remove unwanted clay soils and stains. In fact, most water surfactants by themselves have very poor ability to remove clay soils from fabrics. Not all surfactants work equally well for all types of stains. The addition of a polyamine-based hydrophilic soil dispersant to a laundry detergent composition in addition to a surfactant helps to “push off” clay soil from the surface of the fabric, minimizing the possibility of the clay soil redepositing on the fabric. Stabilize the removed particles in solution to a sufficient extent. However, if the clay cannot be initially removed from the soiled fabric, then there is nothing in the solution to bind the dispersant and keep it suspended, especially in the case of hydrophilic fibers, especially cotton.

There has long been a need in the industry for laundry detergent compositions that can effectively strip and remove embedded clay and other hydrophilic soils from fabrics. Furthermore, as the concentration of hydrophilic soils increases in laundry liquor, there is a need for a surfactant system that can handle this increased soiling. There has also been a long-felt need for clay soil active co-ingredients that can be optimized to suit particular laundry detergent embodiments, especially granules, liquids and tailored to suit surfactant systems. Further, there has been a long-felt need for a method of cleaning hydrophilic soils on fabrics where the hydrophilic soils are effectively peptized, dispersed and suspended in a laundry liquor.

Including the system. The enzyme stabilization system may be any stabilization system that is compatible with the detergent enzyme. Such stabilizing systems may be provided initially with other formulation activators or added individually, for example by the formulator or manufacturer of the detergent enzyme. Such stabilizing systems include, for example, calcium ions, boric acid, propylene glycol, short chain carboxylic acids, boronic acids and mixtures thereof to address different stabilizing problems depending on the type and physical form of the detergent composition. Is designed to

One approach to stabilization is to use a water-soluble source of such ions in the final composition that provides the enzyme with calcium and / or magnesium ions. Calcium ions are usually more effective than magnesium ions and are preferred in the present invention when only one type of cation is used. Typical detergent compositions, especially liquids, range from about 1 to about 30, preferably about 2 to about 20, per liter of final detergent composition.
, More preferably about 8 to about 12 millimoles of calcium ion. However, mutants can also be used depending on factors such as diversity, type and concentration of the incorporated enzyme. Preferably water-soluble calcium or magnesium salts are used, including, for example, calcium chloride, calcium hydroxide, calcium formate, calcium malate, calcium maleate, calcium hydroxide and calcium acetate. More preferably calcium sulfate or magnesium salts corresponding to the demonstrated calcium salts may be used. The use of higher concentrations of calcium and / or magnesium is, of course, useful, for example, to facilitate the fat-scavenging action of certain types of surfactants.

Other stabilization techniques are described in US Pat. No. 4,537,7 issued Aug. 27, 1985.
No. 06 (Severson) borate species. When using the borate stabilizer, it is used at a concentration of up to 10% or more of the composition. However, more generally, boric acid at concentrations up to about 3% by weight, and other borates such as borax or orthoborate are suitable for liquid detergent applications. Substituted boric acids such as phenylboronic acid, butaneboronic acid, p-bromophenylboronic acid, etc. can be used in place of boric acid, and such substituted boron derivatives reduce the total boron concentration in detergent compositions. You can

Some cleaning composition stabilizing systems were further added to prevent chlorine bleach species present in many tap waters from attacking and inactivating enzymes, especially under alkaline conditions. , Preferably about 0.01% to about 10%, preferably about 6% by weight chlorine bleach scavenger. A low chlorine concentration in the water, typically about 0.5 ppm to about 1.75 ppm, for example, results in a relatively large amount of available chlorine in the total volume of water that contacts the enzyme during fabric washing, and thus The stability of the enzyme with respect to chlorine may be problematic. The addition of perborate or percarbonate having the ability to react with chlorine bleach in the particular composition of the present invention may be present in the reduced amount separately from the stabilizing system in the particular composition of the invention, thus adding to counteract chlorine. It is usually not necessary to use the stabilizers mentioned above, but good results are obtained using them. Suitable chlorine scavenger anions are widely known and readily available. When used, it can be a salt containing an ammonium cation together with sulfite, bisulfite, thiosulfite, thiosulfate, iodide and the like. Antioxidants such as carbamates, ascorbates, organic amines such as ethylenediaminetetraacetic acid (EDTA) or its alkali metal salts, monoethanolamine (MEA) and mixtures thereof can likewise be used. Similarly, special enzyme inhibition systems can be incorporated to maximize the compatibility of different enzymes. Bisulfite,
Other common scavengers such as nitrates, chlorides, hydrogen peroxide sources such as sodium perborate tetrahydrate, sodium perborate monohydrate and sodium percarbonate, and phosphates, condensed phosphorus Acid salts, acetates, benzoates, citrates, formates, lactates, malates, tartrates, salicylates and the like and mixtures thereof can be used if desired. In general, the chlorine scavenger function is performed by the components individually listed under the better-recognized function (eg, hydrogen peroxide source), so that compounds that perform that function to the desired extent contain the enzyme of the invention. There is no absolute requirement to add a separate chlorine scavenger, even if it is not present in the embodiment of. Scavengers are added only for best results. further,
The formulator will exercise his normal skill as a chemist in avoiding the use of enzyme scavengers or stabilizers in the formulation that are largely incompatible with other reactive ingredients. With respect to the use of ammonium salts, such salts can be easily mixed with detergent compositions, but tend to absorb water and / or emit ammonia during storage. Therefore, if such a material is present, it should be protected into particles as described in US Pat. No. 4,652,392 issued Mar. 24, 1987 (Baginski et al.). Is desirable.

DISCLOSURE OF THE INVENTION A fully quaternized polyethoxy unit comprises a polyethoxylated polyamine composed of backbone spacer units in which the polyamine backbone is capped with at least one anionic unit and the polyamine backbone is relatively hydrophobic. In a laundry detergent composition, it has been surprisingly found that the polyamines are hydrophobically modified by selecting specific quaternizing units to improve soil removal from clothing. The laundry detergent composition of the present invention is particularly effective in removing clay and other hydrophilic soils from fabrics. When used with a suitable surfactant system, the hydrophobically modified polyamines of the present invention remove stains that were considered destructive to fabrics, especially cellulose-containing fabrics.
