Definitions

• Steps i) and ii) may be reversed.
• the present application further relates to a Benefit Agent peptide/protein deposition aid produced by the above process. Detailed Description
• the peptide/protem Deposition Aid is an enzyme.
• Preferred enzymes are cellulases, lipases, proteases, or cutinases or kerat ases. Cellulases are especially preferred.
• a Benefit Agent can be defined as any agent which effects the feel, appearance, or the perception of a fabric. It is particularly preferred if the Benefit Agent is a fabric softening agent, a perfume, a polymeric lubricant, a photo protective agent (such as a sunscreen), a latex, a resin, a dye fixative agent, an encapsulated material, an antioxidant, an insecticide, a soil repelling agent, a soil release agent
• Suitable cationic softening agents include quaternary ammonium softening compounds having a solubility in water at pH 2.5 and 20°C of less than lOg/1.
• Polyethylene terephthalate/ polyethylene glycol which are disclosed in US 3 557 039 (ICI), GB 1 467 098 and EP 1 305A (Procter & Gamble). Polymers of this type are available commercially, for example, as Per alose, Aquaperle and Milease (Trade Marks, ICI) and Repel-O-Tex SRP3 (Trade Mark, Rhone- Poulenc ) .
• Sulphonated non-end-capped polyester of terephthalic acid, sophthalic acid, sulphoisophthalic acid and ethylene glycol as described in PCT/FR95/00658 (Rh ⁇ ne- Poulenc), published 1 December 1995 and sold commercially as Gerol (Trade mark Rhone-Poulenc ) are also advantageous when used in conjunction with the present invention.
• Suitable materials that may be encapsulated include perfumes, insect repellents, fungicides, or photo protective agents.
• Suitable linking agents are molecules which show a high affinity for the Benefit Agent. It is preferred if the linking agent is covalently attached to the peptide/protem Deposition Aid, it is also advantageous if the linking agent is covalently bound to the Benefit Agent.
• the preferred detergent-active compounds that can be used are soaps and synthetic non-soap anionic and nonionic compounds.
• the total amount of surfactant present will also depend on the intended end use and may be as high as 60 wt%, for example, in a composition for washing fabrics by hand. In compositions for machine washing of fabrics, an amount of from 5 to 40 wt% is generally appropriate.
• the alkali metal aluminosilicate may be either crystalline or amorphous or mixtures thereof, having the general formula:
• Organic builders that may be present include polycarboxylate polymers such as polyacrylates , acrylic/maleic copolymers, and acrylic phosphinates ; monomenc polycarboxylates such as citrates, gluconates, oxydisuccmates , glycerol mono-, di- and t ⁇ succinates , carboxymethyloxysuccinates , carboxymethyloxymalonates, dipicol ates , hydroxyethyliminodiacetates , alkyl- and alkenylmalonates and succinates; and sulphonated fatty acid salts. This list is not intended to be exhaustive.
• organic builders are citrates, suitably used in amounts of from 5 to 30 wt%, preferably from 10 to 25 wt%; and acrylic polymers, more especially acrylic/maleic copolymers, suitably used in amounts of from 0.5 to 15 wt%, preferably from 1 to 10 wt%.
• Builders both inorganic and organic, are preferably present in alkali metal salt, especially sodium salt, form.
• protease obtained from a strain of Bacillus having maximum activity throughout the pH range of 8-12, being commercially available, e.g. from Novo Industri A/S under the registered trade-names Esperase (Trade Mark) and Savinase (Trade-Mark) .
• Esperase Trade Mark
• Savinase Trade-Mark
• Other commercial proteases are Kazusase (Trade Mark) (obtainable from Showa-Denko of Japan), Optimase (Trade Mark) (from Miles Kali-Chemie, Hannover, West Germany) , and Superase (Trade Mark) (obtainable from Pfizer of U.S.A.).
• Detergency enzymes are commonly employed in granular form in amounts of from about 0.1 to about 3.0 wt%.
• compositions of the invention may contain alkali metal, preferably sodium, carbonate, in order to increase detergency and ease processing.
• Sodium carbonate may suitably be present in amounts ranging from 1 to 60 wt%, preferably from 2 to 40 wt%.
• compositions containing little or no sodium carbonate are also within the scope of the invention.
• One preferred powder structurant is fatty acid soap, suitably present m an amount of from 1 to 5 wt%.
• compositions have bulk densities of at least 650 g/litre, more preferably at least 700 g/litre.
• Such powders may be prepared either by post-tower densification of spray-dried powder, or by wholly non-tower methods such as dry mixing and granulation; in both cases a high-speed mixer/granulator may advantageously be used.
• Particles of 0.5um polystyrene latex (ex Polyscience) were taken and the surface functionalised to have free carboxylate groups. The bulk of the particles have small amounts of fluorescent dye incorporated.
• Trichoderma reesei in borate buffer The reactants use left to react overnight.
• a 5% solids dispersion was prepared, where the particles consisted of a surfactant mesophase of composition (by mole fraction) 0.55 octadecanol : 0.40 cetyl sodium sulphonate : 0.05 stearic acid.
• Trichoderma reesei was covalently attached to the particles using the following method:
• the cellulase-modified silicone was incorporated into a model wash and a model rinse. In each case two controls were also used: incorporation of unmodified silicone and the use of no silicone at all.
• the fabrics used in the experiments were 20 x 20 cm squares of white Terry towelling.
• the model washes and rinses were performed in a Tergotometer using the following protocols:
• Example 7 Demonstration of the use of glutaraldehyde as a linking agent.
