Enzymes are normally incorporated in detergent compositions at levels sufficient to provide an "effective amount of cleaning". The term "effective cleaning amount" refers to any amount capable of producing cleaning, strain removal, dirt removal, bleaching, deodorization, or freshness improving effect on substrates such as fabrics. In practical terms for current commercial preparations, typical amounts are up to about 5 mg by weight, more typically 0.01 mg to 3 mg, of active enzyme per gram of the detergent composition. As stated otherwise, compositions herein will typically comprise from 0.001% to 5%, preferably 0.01% -1% by weight and a commercial enzyme preparation. Protease enzymes are usually present in such commercial preparations at levels sufficient to provide 0.005 to 0.1 Anson units (AU) of activity per gram of composition. Higher active levels may be desirable in highly concentrated detergent formulations.

Suitable examples of proteases are the subtilisins that are obtained from particular strains of ß. subtilis and B. licheniformis. A suitable protease is obtained from a strain of Basillus, having maximum activity through the pH scale of 8-12, developed and sold by ESPERASE® by Novo Industries A S of Denmark, hereinafter "Novo".

The LIPOLASA® enzyme derived from Humicola lanuginosa and commercially available from Novo, see also EP 341, 947, is a preferred lipase for use herein. The enzyme-containing compositions herein may optionally also comprise from about 0.001% to about 10%, preferably from about 0.005% to about 8%, more preferably around *. { 3ltli || to about 6% by weight of an enzyme stabilization system. The enzyme stabilization system can be any stabilization system that is compatible with the detersive enzyme. Such a system can be inherently provided by other formulation actives, or it can be added separately, for example, by the formulator or by a manufacturer of detergent enzymes. Said stabilization systems can, for example, comprise calcium, boric acid, propylene glycol, short chain carboxylic acids, boronic acids, and mixtures thereof, and are designed to solve the different problems of stabilization depending on the type and form Physical detergent composition.

E) Preparation of the detergent composition The detergent compositions according to the present invention can be in liquid form, of pasta or granulated. Said compositions can be prepared by combining the essential and optional components in the necessary concentrations in any suitable order and by any conventional means. Granulated compositions, for example, are generally made by the combination of the granular base ingredients, ie surfactants, detergency builders, water, etc., as a suspension, a spray drying causing the suspension to result in a level low residual humidity (5-12%). The remaining dry ingredients, for example, granules of the essential amino acid-based fabric treatment materials, can be mixed in the form of granulated powder with the spray-dried granules in a rotating mixing drum. Liquid ingredients, for example, solutions of fabric treatment materials based on essential amino acids, enzymes, binders and perfumes, can be sprayed into the resulting granules to form the finished detergent composition. The granulated compositions according to the present invention can also be in "compact form", that is, they can have a relatively higher density than conventional granular detergents, ie, from 550 to 950 g / l. In such a case, the granular detergent compositions according to the present invention will contain a low amount of "inorganic filler salt", compared to conventional granular detergents.; Typical filler salts are the alkaline earth metal salts of sulfates and chlorides, typically sodium sulfate; "Compact" detergents typically comprise no more than 10% filler salt. The liquid detergent compositions can be prepared by mixing the essential and optional ingredients in any desired order to provide the compositions containing components in the necessary concentrations. The liquid compositions according to the present invention may also be in "compact form", in which case, the liquid detergent compositions according to the present invention will contain a lower amount of water, compared to conventional liquid detergents. The addition of the polymeric, oligomeric or copolymer materials based on amino acids to the liquid detergent or other aqueous compositions of this invention can be achieved by simple mixing in the liquid solutions to the fabric treatment materials based on desired amino acids.

F) Fabric laundry method The present invention also provides a method for fabric laundry in a form that imparts the fabric appearance benefits provided by the polymer, oligomer or copolymer materials based on amino acids used herein. Said method employs contacting said fabrics with an aqueous wash solution formed of an effective amount of the detergent compositions described above or formed of the individual components of said compositions. The contact of the fabrics with the washing solution will generally occur under agitating conditions, although the compositions of the present invention can also be used to form aqueous solutions of lathering without shaking for fabric cleaning and treatment. As described above, it is preferred that the wash solution has a pH of less than about 10.0, preferably having a pH of about 9.5 and more preferably having a pH of about 7.5. The stirring preferably is provided in a washing solution machine for good cleaning. Preferably washing is followed by drying the wet fabric in a conventional clothes dryer. An effective amount of a high density liquid or granular detergent composition in the aqueous wash solution in the washing machine is preferably from about 500 to about 7000 ppm, more preferably from about 1000 to about 3000 ppm.

G) Fabric Conditioning The polymer, oligomer or copolymer materials based on amino acids, described above as components of laundry detergent compositions herein, can also be used to treat and condition fabrics and textiles in the absence of a surfactant and builder components of the composition and detergent embodiments of this invention. Thus, for example, a fabric conditioning composition comprising only the same fabric treatment materials based on amino acids, or comprising an aqueous solution of the fabric treatment materials based on amino acids, can be added during the rinsing cycle of a conventional domestic laundry operation in order to impart the desired appearance and integrity benefits of the fabric described above.

General Appearance In a general appearance test, the fabrics are washed using several test compositions which do not contain lysine / carboxylic acid polymers (control) or one of the polymers defined in the following Table IX. The fabrics are washed and after ten cycles are evaluated comparatively by three judges, who evaluate the general appearance of the washed fabrics. The judge is the one who decides what to evaluate unless there is a specific address to evaluate an attribute such as color, ball formation, fluff, etc.

In the general appearance test, the visual preference of the judge is expressed using the Scheff scale. That is: 0 = No difference. 1 = I think this one is better (insecure). 2 = I know this one is a little better. 3 = I know this one is much better. 4 = I know that this one is much better. For the general appearance test, the laundry conditions are as follows: Type of washing machine: Kenmore (64.26 liters) Washing time: 12 minutes Washing temperature: 32.2 ° C Washing water hardness: 6 grains per 3.78 liters Agitation of washing machine: normal Rinse time: 2 minutes Rinse temperature: 15.6 ° C Rinse water hardness: 6 grains per 3.78 liters Content of washing load fabric: various clothes and fabrics with color and white. Washing load weight: 2.5 kg. The results of the average general appearance test are shown in Table IX.
