Definitions

  • the invention relates to a process for treatment of textiles by use of a lipase.
  • Treatment of soiled or unsoiled textiles normally comprises washing with a detergent containing anionic and/or nonionic surfactant, followed by rinsing and drying. It belongs to the prior art that lipase can be incorporated into the detergent to improve the removal of fat soiling (EP 130,064, EP 214,761, US 4,810,414).
  • a non-dusting granulate containing a cellulase can be added to a main wash detergent composition in order to reduce the harshness of the laundry (US 4,435,307), that proteases are useful in detergent compositions in order to remove proteinaceous stains (US 3,723,250), and that amylases are useful in detergent compositions in order to remove starchy stains (US 3,627,688 and 4,548,727).
  • a given enzyme may be incompatible with a given detergent composition due to unsatisfactory activity and stability of the enzyme, and this imposes some limitations in the choice of enzyme and detergent formulation. It is the object of the invention to provide an alternative method of using a lipase in textile treatment, so as to obtain efficient lipolytic effects for a given lipase dosage while avoiding the above limitations.
  • a lipase provides a better lipolytic effect when used in the rinse liquor than when used as a constituent of the main wash composition.
  • the effect is particularly pronounced after repeated cycles of washing, rinsing and drying.
  • Detergent is essentially absent during rinsing, and thus compatibility problems are avoided.
  • the lipase may advantageously be added in the last rinse step together with a cationic surfactant.
  • the invention provides a process for treatment of textiles by use of a lipase, which is used in a rinse liquor for a rinsing step after washing, characterized by the fact that the lipase is producible by means of Humicola lanuginosa or Pseudomonase cepacia.
  • the lipase is used in the rinse liquor for the rinsing step after washing, together with a fabric softening agent and/or an antistatic agent.
  • the fabric softening agent and/or the antistatic agent is a cationic surfactant.
  • the cationic surfactant may be a dialkyl dimethyl ammonium chloride or an alkyl imidazoline methosulfate.
  • the enzyme is used in the rinse liquor for a second or later rinsing step, preferably in the last rinsing step. In this manner an even better enzymatic effect is observed.
  • the concentration of lipase in the rinse liquor is in the range of 0.001 to 5, preferably 0.01 to 2 mg pure lipase protein per liter of rinse liquor. At a concentration below 0.001 mg pure lipase protein per liter of rinse liquor no significant lipase effect can be observed, and at a concentration above 5 mg pure lipase protein per liter of rinse liquor the lipase cost will be unreasonably high.
  • the lipases which can be used in the invention are lipases producible by means of Humicola lanuginosa (US 4,810,414) and Pseudomonas cepacia (WO 89/04361).
  • the lipase activity unit, LU is defined in AF 95/5, which is available on request from Novo Nordisk A/S, Novo allé, DK-2880 Bagsvaerd, Denmark, this publication being published before March 1, 1990.
  • a cationic surfactant effective for fabric after-treatment is used together with the lipase in the process according to the invention.
  • cationic surfactants are known in the art.
  • One example is quaternary ammonium salts such as dialkyl (C16-C18) dimethyl ammonium chloride, alkyl (C32-C36) trimethyl ammonium chloride or alkyl (C8-C18) dimethyl benzyl ammonium chloride (ABDAC); and alkyl imidazolinium methyl sulphate.
  • the invention uses a lipase in the rinsing stage of a conventional treatment process for soiled or unsoiled fabrics comprising washing, rinsing and drying.
  • the rinsing stage generally comprises 2-5 subsequent steps of rinsing with water, usually 3 or 4 steps.
  • the lipase is added together with a cationic surfactant (e.g. 0.1-0.5 g/l).
  • the lipase is preferably added in the second or a later rinsing step, and most preferably in the last rinsing step, where the detergent concentration is lowest (thus minimizing any incompatibility problems between detergent and lipase) and where it can conveniently be added together with the cationic surfactant, if such cationic surfactant is used in the process according to the invention.
  • Conventional rinsing conditions can be used, e.g. 10-30°C water, 1-20 minutes at near-neutral pH (e.g. 5-9) depending on the use of cationic surfactant.
  • the rinsing agent used in the process according to the invention is stabilized against microbial infection, preferably by incorporation of a stabilizing agent known in the art.
  • a stabilizing agent known in the art.
  • examples are inorganic salts (such as NaCI), sugars (such as sucrose and glucose), polyols (such as glycerol, propylene glycol and sorbitol) and alcohols (such as ethanol and iso-propanol). These are generally effective in amounts above 10%, especially above 20%.
  • organic acids such as benzoic, sorbic, propionic, lactic and formic
  • stabilizing agents are antioxidants (such as sulphur dioxide), 1,2-benz-iso-thiazolin-3-on (BIT) and parabens. Some of these may also serve to improve enzyme stability.
  • Further additives may be incorporated to improve enzyme stability or physical stability of the rinsing agent.
  • Examples are CaCl2 (e.g. 0.1-0.5%) or 0.5-5% of lower alcohol (such as ethanol or iso-propanol, preferably used together with a larger amount of a polyol).
  • the rinsing agent ordinarily is preferably essentially devoid of anionic and nonionic surfactant (total amount of these below 5%, most preferably below 2%).
  • the rinsing agent may be in solid (e.g. as non-dusting granules) or liquid form (e.g. aqueous). It may be formulated by incorporating lipase into known softening/antistatic compositions based on cationic surfactants.
  • the content of cationic surfactant is preferably 1-50%, especially 5-50% (% as active material).
  • the lipase used in the examples is from Humicola lanuginosa produced according to US 4,810,414 or from Pseudomonas cepacia produced according to WO 89/04361.
  • Example 2 The performance evaluation was carried out as described in Example 1, the only difference being that other kinds of cationics were used in combination with the Humicola lanuginosa lipase and that the lipase dosage was varied between 0 and 3000 LU per litre.
  • the cationics used were:
