Description

The detergent composition that comprises mannase and percarbonate

Invention field

The present invention relates to comprise the detergent composition of mannase and percarbonate.

Background of invention

Perborate is familiar with by those skilled in the art as laundry or dishwashing detergent additive, and it provides available oxygen by the hydrogen peroxide releasing mechanism.Perborate is widely used in detergent for washing clothes or the dish washing detergent with its attracting price owing to it is high-effect.

But, have realized that in this area discharging the by product that forms in the hydrogen peroxide by perborate is that the metaborate derivative cooperates with glycopolymers such as starch and negative impact cleaning (EP-A-736085).Find uncannily that now thereby seminose polymkeric substance such as guar gum also more is difficult to remove by containing the perborate washing composition with crosslinked food or the makeup spot of making of perborate.Now find uncannily in addition to have reduced the activity of enzyme to this natural gum/borate title complex substrate with the crosslinked borate of guar gum.

Really, the foods and cosmetics stain is the most consumers stain of often meeting and generally includes foodstuff additive such as viscosifying agent/stablizer.Hydro-colloid natural gum and emulsifying agent are the foodstuff additive of using always.Described term " natural gum " is meant industrial available polysaccharide (long chain polymer) or derivatives thereof, and its hydration in hot water or cold water forms viscous soln, dispersion or gel.Natural gum is classified as natural gum and modification natural gum.Natural gum comprises Seaweed Extract, plant extrudate, from the natural gum of seed or root and the natural gum that obtains by microbial fermentation.(semi-synthetic) natural gum of modification comprises Mierocrystalline cellulose and starch derivative and some synthetic gum such as low-methoxy pectin, propylene glycol alginate and carboxymethyl and Rhoximat RH 148 (referring to J.Baird, the gummy chapters and sections during the 4th edition Encyclopedia ChemicalTechnology the 12nd of Kelco division of Merck rolls up 842 to 862 pages).Also referring to Carbohydrate Chemistry for Food Scientists (the Eagan press of R.L.Whistler and J.N.BeMiller, 1997) Direct Food Additives inFruit Processing (the Technomie press of 66 to 89 pages in the 4th chapter and P.Laslo, 1996), Bioprinciples andApplications, 313 to 325 pages in the 1st volume 11 chapters.Some these class natural gum such as guar gums (E412), Viscogum BE (E410) extensively are used alone or are used in combination (referring to J.Baird, the gummy chapters and sections during the 4th edition EncyclopediaChemical Technology the 12nd of Kelco division of Merck rolls up 842 to 862 pages) in numerous food product processing.

Used guar gum obtains from the seed endosperm of leguminous plants cyamopsis tetragonolobus (Cyamopsis tetragonoloba) in these foods and cosmetics spots.The guar gum (also claiming guaran) that extracts from described dicotyledonous seed comprises 1-4 b-D-pyran-mannose glycosylation unit main chain and be used as viscosifying agent (H.D.Belitz seasonings and frozen product and makeup, Food Chemistry, 243 pages, the English edition of second edition, Springer-verlag, 1987, ISBN0-387-15043-9, the U.S.) and (Carbohydrate Chemistry for Food Scientists, R.L.Wilstler, Eagan Press, 1997, ISBN0-913250-92-9) and (Industrial Gum, second edition, R.L.Whistler, 308 pages, Academic Press, 1973, ISBN0-12-74-6252-x).(be also referred to as tragon or St Jon ' sbread) also is used in the foodstuffs industry and extracts from the seed of a kind of evergreen plant of Mediterranean Zone plantation Viscogum BE.The structural difference of Viscogum BE and guar gum may be that the number and the Viscogum BE of its less D-galactosyl side chain has same 1-4 b-D-pyran-mannose glycosylation main chain.In seeds of leguminous plant, water miscible polygalactomannan is main storage carbohydrate, in some cases up to 20% of gross dry weight.Polygalactomannan have α-semi-lactosi linking to each other with the O-6 of mannose residue and can be on the O-2 of mannose residue and O-3 acetylize to various degree.

In addition, but percarbonate the effect of bleach spot extensively is familiar with by those skilled in the art.The activeconstituents that disengages from percarbonate is H ₂O ₂Identical with the activeconstituents that disengages from perborate, but disengaging of borate substance do not had.Be used in combination (particularly being used in combination by specified level) of now finding percarbonate and mannase uncannily provides difficult removal spot such as the foods and cosmetics spot that comprises mannosans special synergy removal effect at low temperatures.

Now also discovery comprises that the ternary system of the percarbonate/mannase/proteolytic enzyme of specified level provides the better removal effect of described spot.

Alleged occurrence mannase in several genus bacillus bodies.For example people such as Talbot to have described molecular weight 3505 to 3510 pages of the Appl.Environ.Microbiol. of 56 11 phases of volume of nineteen ninety be that 162kDa and best pH are the 'beta '-mannase that comes from bacstearothermophilus (Bacillus stearothermophilus) of the dipolymer form of 5.5-7.5.People such as Mendoza 551 to 555 pages of World J.Microbio.Boitech. of 1994 10 5 phases of volume described the molecular weight of a kind of 38kDa of having and the optimum activity under pH5.0 and 55 ℃ and 4.8 pI (iso-electric point), come from the 'beta '-mannase of subtilis (Bacillus subtilisis).J0304706 disclose the best pH of molecular weight that a kind of gel-filtration with 37 ± 3kDa records, 8-10 and 5.3-5.4 pI, come from the B-mannase of bacillus bacterial classification (Bacillussp.).J63056289 has described for example β of mannosans-1 of a kind of hydrolysis, the 4-D-mannopyranose glycosidic bond and the alkalescence of generation manna oligosaccharide, the production of thermally-stabilised 'beta '-mannase.J63036774 relates to the bacillus micro-organism FERM P-8856 that produces 'beta '-mannase and beta-Mannosidase under alkaline pH.Mannase of a kind of purifying that comes from bacillus amyloliquefaciens (Bacillus amyloliquefaciens) that can be used for bleached pulp and paper and preparation method thereof is disclosed among the WO97/11164.WO91/18974 has described under extreme pH and temperature has active hemicellulase such as dextranase, zytase or mannase and production thereof.WO94/25576 discloses and a kind ofly demonstrated the mannosans enzymic activity, the enzyme of (Aspergillus aculeatus) CBS101.43 that comes from microorganism Aspergillus aculeatus, and it can be used for the degraded or the modification of plant or alga cells wall material.WO93/24622 disclose can be used for the bleaching lignin cellulose pulp, from the isolating mannase of Trichoderma (Trichoderma reesie).

But, the synergistic combination of described mannase and percarbonate in detergent composition excellent cleaning performance, promptly excellent greasiness removal, particularly the usefulness of the removal that contains mannosans makeup and food stain, dirty thing cleaning and whiteness maintenance was not before recognized by the people.

In addition, the usefulness of the cleaning performance of the synergistic combination of described mannase and percarbonate and proteolytic enzyme excellence in detergent composition, i.e. excellent greasiness removal, dirty thing cleaning and whiteness maintenance before was not familiar with by the people.

The present invention's summary

The present invention relates to comprise the detergent composition of mannase and percarbonate.These compositions provide excellent clean-up performance, the usefulness that promptly provide excellent greasiness removal, particularly the removal that contains mannosans makeup and food stain, dirty thing cleaning and whiteness is kept.

Detailed description of the present invention

A basal component of detergent composition of the present invention is a mannase.The use of mannase will provide makeup that comprise hydro-colloid natural gum such as guar gum and the significant clean effect of food stain.

We find that uncannily the composition of perborate and mannase only provides limited usefulness, believe this limited usefulness be since can with the existence of the crosslinked metaborate of the hydro-colloid natural gum that exists in the spot.On the contrary, have now found that percarbonate (material of available oxygen is provided) provides outstanding synergy cleaning performance with mannase of the present invention under the situation that does not form the metaborate derivative.

Therefore, the present invention relates to the purposes of the mannase that is used in combination with percarbonate.This combination provides brightens and/or greasiness removal usefulness the outstanding synergy of foods and cosmetics spot of hydro-colloid natural gum such as guar gum that comprises the mannase sensitivity or Viscogum BE.Be not wishing to be bound by theory, believe percarbonate bleach not be present in spot in natural gum therefore cooperate and be convenient to enzyme and/or SYNTHETIC OPTICAL WHITNER near described spot.In addition, believe that this synergism is because a) use that does not have crosslinked percarbonate and the b of bleaching gummy chromophoric group spot) mannase is to the effect of hydrocolloid polymer, and formed more diffluent little residue and provide known efficient removal effect to the affine hydro-colloid residue of the cotton surface elevation of clothing.In addition, believe described synergism be since do not exist known can with the crosslinked borate ion of the guar gum of hydration (referring to Industrial Gum, second edition, the R.L.Whistler work, 317 pages, Academic Press, 1973, ISBN0-12-74-6252-x).
