COMPOSITIONS DETERGENT PORO flVflNDERIñ THAT CONTAIN ENZIMA LIPOLITICñ AND FLMINñ
CHAMBER OF L INVENTION
The present invention relates to laundry detergent compositions containing ipolytic enzyme (lipase) and specially selected unary and / or tertiary amines. The compositions provide improved cleanliness of soils and grease / oil stains, particularly when used in a pretreatment laundry cleaning procedure for grease / oil stains.
BACKGROUND OF THE INVENTION
The inclusion of lipase in detergent compositions for improved cleaning performance is known, for example, by increasing the removal of dirt and stains with two on the two fabrics. Examples are the Patent of EUR 4,769,173; Patent of EUR 5,069,009; Solici +? D of PCT UO94 / 0357R. No. 4,769,173 discloses a certain class of lipases which consist of fungal lipases from ex Hurnicola lanuginosa together with heavy blotting agents in detergent compositions. An example of a fungal lipase in this patent is the l pass of ex Humicola lanugmosa, available from Hmano ba or the trade name Amano-CE. No. 5,069,809 describes the combination of strong cleaning agents with a lipase enzyme produced by cloning the gene encoding the lipase produced by Humicola lanugmosa and expressing the gene in fispergillus oryzae as a host for use in detergent compositions. No. 94/03578 discloses an enziotic detergent composition containing 10 to 20,000 LU (lipolytic units) per unit of a 11-pass detergent composition that exhibits substantial Jipolitic activity during the main cycle of a washing process. this lipase is selected particularly for its inactivation behavior with diisopropyl fluorophosphate (DFP). Of the lipase enzymes, only the lipase derived from Húmicola lanuginosa and produced in Ospergillus oryzae as a host has found wide application as an additive for fabric washing products, is available under the trade name Lipolase *, from Novo No dis. ñ In order to optimize the stain removal performance of Lipo ase, Nevo Nordis has made a number of variants. 92/05249 describes the vanant D96I of the native lipase of Humicola lanuginosa that improves the efficiency of butter spot regeneration by a factor of 4.4 over the wild-type lipase (enzymes compared in an amount varying from 0.075 to 2.5 rn protein per liter). The ability of the lipase to clean dirt and stains from fabrics present in the typical laundry load is of utmost importance in the evaluation of detergent yield. Unfortunately, the relative ability of the unit to meet various performance criteria among other things depends on the presence of surfactant co-agents. Therefore, for reasons of performance and flexibility, it is desired to make available a surfactant system capable of providing buoyant performance of detergent. The above objective has been met by a surfactant system comprising a co-surfactant selected from the group of primary or tertiary amines. Surprisingly it has been found that the inclusion of specially selected primary or tertiary amines in liquid detergent compositions containing lipolytic enzyme (lipase) substantially increases their ability to rapidly reduce the surface tension of aqueous washing solutions than with oil and grease. Substantial reduction in the interfacial tension of oily and oily soils improves their removal from soiled surfaces and inhibits the redeposition of soils onto substrates. It has also surprisingly been found that liquid detergent compositions containing a lipolytic enzyme and a specially selected primary or tertiary amine show smerge removal of greasy / oily soils particularly when the detergent composition is used in a pretreatment application for stains or oily / oily soils on the fabrics before and together with the washing procedure nor ai of the tolas.
ENZIMA LIPOLITICfl
An essential ingredient in the present laundry detergent compositions is a yield increasing amount, preferably from about 0.0001 to 1.0% on an active basis, of a lipase comparable with detergent (lipolytic enzyme). By "detergent compatible" is meant compability with the other ingredients of the composition, particularly detergent surfactants and detergency builders. Liquid detergent compositions, particularly heavy duty liquids, are preferred herein. Any suitable lipase for use in a laundry detergent composition can be used herein. Lipases suitable for use herein include those of bacterial and icotic origin. The lipase of chemically or genetically modified utants is included in the present invention. Suitable bacterial lipases include those produced by pseudomonas, such as Pseudomonas stutzeri OTCC
19. 154, as described in British Patent 1,372,034, incorporated herein by reference.

A particular preferred polymer in accordance with EP-A-0 272 033 has the formul (CH3 (PEG) A3)? 7S (P0H ) 0.2SCT-P0) 2.8 (T ~ PEG) 0.4] T (P0- H) O.2S ((PEOÍ3CH3)? 75 where PEG is - (OC2H4) 0-, PO is (OC3H6O) and T is ( They are also very useful on polyesters such as random copolymers of di-ethyl terephthalate, dimethyl-sulphonophthalate, ethylene glycol and 1-2-propanediol, the end groups consisting mainly of sulfobenzoate and secondarily of onosters of ethylene glycol and / or propanediol. is to obtain a polymer blocked at both ends by sulfobenzoate groups, "primarily", in the present context most of said copolymers will be blocked at the ends by sulfobenzoate groups, however, some copolymers will be less completely blocked, and therefore its extreme groups may consist of mono esters of ethylene glycol and / or propanol-2-diol, of the same consists "secondarily" of said species. The polyesters selected herein contain about 46% by weight of dimethylterephthalic acid, about 16% by weight of propane-1,2-diol, about 10% by weight of ethylene glycol, about 13% by weight of dirnemisulfobenzoic acid and about 15% by weight of acid sulfoisophthalic, and have a molecular weight of about 3,000. The polyesters and their method of preparation are described in detail in EPA 311 342. Particularly suitable soil release polymers include oligomeric esters such as described in the co-pending US Patent Application. No. 08/355/938 filed on December 14, 1994. Said esters comprise: (1) a base structure copying (a) at least one unit selected from the group consisting of dihydroxy or polyhydroxy sulfonate, a unit which it is at least tri functional by which the ester linkages are formed resulting in a branched oligorne base structure, and combinations thereof; (b) at least one unit that is a terefta1oi 1o portion; (c) at least one unsubstituted unit which is a 1,2-oxyalkenyloxy portion; (2) one or more blocking units (non-ionic and / or ammonia).
The preferred ester molecules have the following structure (For-rnu i a A):
where R = H, CH3 in relation of 1.7: 1, which is a plo axis of an oligomer having three SE3 blocking units, a SEG unit, and a glycerin unit incorporated in the structure of the oligomer. Other components used in detergent compositions may be employed, such as soil suspending agents, abrasives, bactericides, rinse inhibitors, coloring agents, foam control agents, corrosion inhibitors and perfumes. Preferably, the liquid compositions according to the present invention are in "concentrated form"; in such a case, the liquid detergent compositions in accordance with the present invention will contain a lower amount of water, compared to conventional liquid detergents. The water level is less than 50%, preferably less than 30% by weight of the detergent compositions. Such concentrated products provide advantages to the consumer, who has a product that can be used in lower quantities and to the producer, who has lower shipping costs. Liquid compositions are especially effective when applied directly to soils and stains in a pretreatment step. The detergent compositions of the present invention can also be used as detergent additive products. Said additive products complement or increase the performance of conventional detergent compositions. The detergent compositions according to the present invention include compositions to be used for cleaning substrates., such as fabrics, fibers, hard surfaces, skin, etc., for example surface cleaning compositions last (with or without abrasives), laundry detergent compositions, automatic and non-automatic dishwashing compositions. The following examples illustrate compositions of the present invention, but do not necessarily limit the scope of the invention.
