Definitions
- the present invention is in the field of laundry.
- it relates to a method of industrial or institutional laundry for a polyester load using a silicone suds suppressor during the wash process.
- detergents for household (or home) and professional (including institutional and industrial) laundries are similar, detergents for large-scale institutional or industrial use generally differ insofar as they must be designed to meet the special circumstances associated with laundry on an industrial scale and/or in an institutional context. Contrary to home laundry, professional laundries have to deal with large volumes of textile items and require therefore completely automatic processing with microprocessor-controlled machines and dosing units.
- the length of the washing process differs from that of home laundry and in some cases the washing is performed with soft water. Soil levels can be significantly lower in certain types of loads of professional laundry (for example towels and bed linen in a hotel which have minimal use and soiling before being re-washed) than in household laundry and the loads and the machines are considerably bigger.
- the composition of the loads is more uniform, in terms of both, types of fabrics and soils. For example a typical commercial laundry load will consist of only towels, only bed linen or only table linen (tablecloths and napkins).
- Soft water also promotes sudsing. Under these circumstances, it is difficult to perform a good cleaning.
- Fatty acids or fatty soaps are commonly used as suds suppressors in laundry. They rely on the presence of water hardness ions to work. When water hardness ions are present they can form salts which can disrupt the suds. If there are no water hardness ions, as the case is with soft water, then the soap might even cause additional suds. It has been found that if a load of polyester is washed in soft water, using a normal amount of detergent, the level of suds can be so high that it can overflow the machine, this seems to be worse when the level of soil is low.
- a method of cleaning a polyester load in a professional laundry machine comprises subjecting the load to main-wash, rinse and optionally pre-wash cycles and wherein the method comprises the step of contacting the load with an aqueous wash liquor containing a detergent composition comprising a silicone suds suppressor.
- polyester load is understood a load comprising at least about 50%, preferably at least about 60%, more preferably at least about 80% and more preferably at least 95% by weight of the load of polyester items.
- the level of anionic surfactant is greater than 10%, more preferably greater than 15% and especially greater than 20% by weight of the detergent composition. This provides an outstanding cleaning over a great range of soils.
- the detergent composition preferably comprises non-ionic surfactant and anionic surfactant.
- the level of anionic surfactant is higher than the level of non-ionic surfactant, by “higher” is herein meant that the level of anionic surfactant is at least 1% by weight more than the level of non-ionic surfactant, preferably at least 5%, more preferably at least 15% and especially at least 20%.
- the level of non-ionic surfactant is less than 10% by weight of the detergent composition.
- the method of the invention also allows for flexibility in terms of detergent formulation.
- Polyester with low level of soil and new polyester items can be even more prone to sudsing than highly soiled items.
- the method of the invention performs very well even in the case of loads with low level of soil (typically towels or bed linen) or new items.
- low soiled items is herein understood items free from visible stains.
- new items is herein understood items that have not been subjected to a washing process.
- the liquor of the method of the invention preferably the liquor of each cycle, has a hardness, i.e., Ca and Mg ions concentration, of less than about 1, preferably less than about 0.5 and especially less than about 0.2 mmoles/litre.
- the method of the invention involves the step of heating the cleaning water using steam, in particular steam injection.
- Preferred suds suppressor for use herein is a polydimethylsiloxane compounded with silica.
- the wash liquor preferably the wash liquor of the main wash, has a pH of from about 7 to about 10, preferably from about 8 to about 9, as measured at room temperature (20° C.) this allows not only for good cleaning but also for good care of the washed articles.
- the detergent composition comprises anionic surfactant, preferably in a level of at least 10%, more preferably at least 12% by weight of the detergent composition, and at least 50%, preferably at least 70% and more preferably at least 80% by weight of the anionic surfactant is an alkyl benzene sulfonated (LAS).
- anionic surfactant is an alkyl benzene sulfonated (LAS).
- LAS alkyl benzene sulfonated
- the method of the invention comprises the step of contacting the load with a soil release polymer, in any of the wash cycles, preferably during the main-wash or a rinse cycle.
- a soil release polymer is added as part of an additive rather than as part of a detergent composition. This not only obviates the process challenges found to make the soil release polymer part of a base detergent but also eliminates the interaction between some of the base detergent ingredients and the polymer and gives flexibility in terms of dosing.
- the present invention envisages a method of professional laundry of a polyester load.
- the method involves contacting the load with a detergent comprising a silicone suds suppressor.
- the method provides improved cleaning. It has been found that the problem of high suds is more acute in the case of a load with low level of soil, ie. a load with less than 10 g of soil per kilogram of load, preferably with less than 5 g of soil per kilogram of load.
- the polyester load used in the method of the present invention is a load with low level of soil.

Abstract
A method of cleaning a polyester load in a professional laundry machine the method comprises subjecting the load to main-wash, rinse and optionally pre-wash cycles and wherein the method comprises the step of contacting the load with an aqueous wash liquor containing a detergent composition comprising a silicone suds suppressor.
Description
- This application claims the benefit of U.S. Provisional Application Ser. No. 61/160,426, filed 16 Mar. 2009.
- The present invention is in the field of laundry. In particular, it relates to a method of industrial or institutional laundry for a polyester load using a silicone suds suppressor during the wash process.
- Even though the principles that determine the effectiveness of detergents for household (or home) and professional (including institutional and industrial) laundries are similar, detergents for large-scale institutional or industrial use generally differ insofar as they must be designed to meet the special circumstances associated with laundry on an industrial scale and/or in an institutional context. Contrary to home laundry, professional laundries have to deal with large volumes of textile items and require therefore completely automatic processing with microprocessor-controlled machines and dosing units. The length of the washing process differs from that of home laundry and in some cases the washing is performed with soft water. Soil levels can be significantly lower in certain types of loads of professional laundry (for example towels and bed linen in a hotel which have minimal use and soiling before being re-washed) than in household laundry and the loads and the machines are considerably bigger. The composition of the loads is more uniform, in terms of both, types of fabrics and soils. For example a typical commercial laundry load will consist of only towels, only bed linen or only table linen (tablecloths and napkins).
- Due to the size of the washing equipment, professional laundry involves higher mechanical action than home laundry and this promotes foaming. Foaming is also promoted in the case of laundry loads consisting mainly of synthetic fabrics, in particular polyester fabrics. Polyester items are hydrophobic and they are not capable to absorb surfactants. During the washing process, polyester items seem to be less densely packed than cotton items, being more prone to sudsing. Suds negatively affect the laundry cleaning performance because contributes to the suspension of items in the wash liquor precluding the free rise and fall of the items, leading to reduction of mechanical action which is one of the major elements contributing to cleaning.
- Low sudsing in washing polyester loads could be achieved through the selection of inherently low sudsing surfactants, primarily non-ionics, versus the use of anionics, for example. However this leads to poor performance on certain varieties of soils, because this limits the selection to potentially compromised-in-performance surfactants. An approach to overcome this lost of performance is the addition of high levels of alkalinity, as alkalinity itself can help drive soil removal. But alkalinity can drive (alkaline) hydrolysis of the polyester molecules that comprise the fibers, and thus damage the very fabrics intended for cleaning. The alkalinity can also drive mineral salt encrustation and many other issues.
- Some of the professional laundry systems involve the use of soft water. Soft water also promotes sudsing. Under these circumstances, it is difficult to perform a good cleaning.
- Fatty acids or fatty soaps are commonly used as suds suppressors in laundry. They rely on the presence of water hardness ions to work. When water hardness ions are present they can form salts which can disrupt the suds. If there are no water hardness ions, as the case is with soft water, then the soap might even cause additional suds. It has been found that if a load of polyester is washed in soft water, using a normal amount of detergent, the level of suds can be so high that it can overflow the machine, this seems to be worse when the level of soil is low.
- According to a first aspect of the invention, there is provided a method of cleaning a polyester load in a professional laundry machine. The method comprises subjecting the load to main-wash, rinse and optionally pre-wash cycles and wherein the method comprises the step of contacting the load with an aqueous wash liquor containing a detergent composition comprising a silicone suds suppressor.
- By polyester load is understood a load comprising at least about 50%, preferably at least about 60%, more preferably at least about 80% and more preferably at least 95% by weight of the load of polyester items.
- It has been found that textile loads containing a high level of polyester items give rise to high suds that impact negatively in the cleaning process. The method of the invention provides improved cleaning.
- In a preferred embodiment the level of anionic surfactant is greater than 10%, more preferably greater than 15% and especially greater than 20% by weight of the detergent composition. This provides an outstanding cleaning over a great range of soils. The detergent composition preferably comprises non-ionic surfactant and anionic surfactant. The level of anionic surfactant is higher than the level of non-ionic surfactant, by “higher” is herein meant that the level of anionic surfactant is at least 1% by weight more than the level of non-ionic surfactant, preferably at least 5%, more preferably at least 15% and especially at least 20%. Preferably the level of non-ionic surfactant is less than 10% by weight of the detergent composition. The method of the invention also allows for flexibility in terms of detergent formulation.
- Polyester with low level of soil and new polyester items can be even more prone to sudsing than highly soiled items. The method of the invention performs very well even in the case of loads with low level of soil (typically towels or bed linen) or new items. By the term “low soiled items” is herein understood items free from visible stains. By the term “new items” is herein understood items that have not been subjected to a washing process.
- As mentioned above, soft water further contributes to aggravate the suds problem. In preferred embodiments the liquor of the method of the invention, preferably the liquor of each cycle, has a hardness, i.e., Ca and Mg ions concentration, of less than about 1, preferably less than about 0.5 and especially less than about 0.2 mmoles/litre.
- Another factor that further aggravates the suds problem is heating by steam means. In another embodiment the method of the invention involves the step of heating the cleaning water using steam, in particular steam injection.
- Excellent cleaning is obtained with the method of the invention, even when using soft water and when the water is heated by steam means.
- Good cleaning performance is obtained when the level of active suds suppressor in the wash liquor is from about 0.1 to about 10, more preferably from about 0.2 to about 5 and especially from about 0.8 to about 3 ppm. Preferred suds suppressor for use herein is a polydimethylsiloxane compounded with silica.
- In preferred embodiments the wash liquor, preferably the wash liquor of the main wash, has a pH of from about 7 to about 10, preferably from about 8 to about 9, as measured at room temperature (20° C.) this allows not only for good cleaning but also for good care of the washed articles.
- In preferred embodiments the detergent composition comprises anionic surfactant, preferably in a level of at least 10%, more preferably at least 12% by weight of the detergent composition, and at least 50%, preferably at least 70% and more preferably at least 80% by weight of the anionic surfactant is an alkyl benzene sulfonated (LAS). Detergents rich in LAS, used according to the method of the invention, provide not only good cleaning but also have a low suds profile.
- In preferred embodiments the method of the invention comprises the step of contacting the load with a soil release polymer, in any of the wash cycles, preferably during the main-wash or a rinse cycle. Preferably the soil release polymer is added as part of an additive rather than as part of a detergent composition. This not only obviates the process challenges found to make the soil release polymer part of a base detergent but also eliminates the interaction between some of the base detergent ingredients and the polymer and gives flexibility in terms of dosing.
- The present invention envisages a method of professional laundry of a polyester load. The method involves contacting the load with a detergent comprising a silicone suds suppressor. The method provides improved cleaning. It has been found that the problem of high suds is more acute in the case of a load with low level of soil, ie. a load with less than 10 g of soil per kilogram of load, preferably with less than 5 g of soil per kilogram of load. Preferably the polyester load used in the method of the present invention is a load with low level of soil.
- Professional laundry includes institutional and industrial (sometimes also referred to as commercial) laundry. Institutional laundry refers to textile washing operations usually run in business sites, normally referred to as On-Premise or In-House Laundry Operations. Typical businesses can be for instance hotels, restaurants, care homes, hospitals, spas, health or sport clubs, schools, and similar institutions. Industrial laundry refers to textile washing operations carried out in dedicated places typically for the above businesses.
- By “professional laundry machine” is herein meant a laundry machine which a capacity higher than 8 kg, preferably higher than 15 kg and more preferably higher than 25 kg of dry laundry. There are two main types of professional laundry machines: front load which operate in a batch mode or tunnel washing machines that operate in continuous mode. The professional laundry machines for use herein, in the case of front load have a drum volume of at least about 0.15 m3, preferably at least 0.2 m3, more preferably at least 0.3 m3 and especially at least 0.5 m3. The professional laundry machines for use herein, in the case of front load have a drum diameter of at least about 0.5 m, preferably at least 0.8 m and more preferably at least 1 m. In the case of tunnel washing machines the tunnel has a diameter of at least about 1.5 m, preferably at least 3 m and more preferably at least 5 m.
- Silicone Suds Suppressor
- Silicone suds suppressor is defined herein as any antifoam compound including a silicone component. Such silicone suds suppressor also typically contains a silica component. The term “silicone” as used herein, and in general throughout the industry, encompasses a variety of relatively high molecular weight polymers containing siloxane units and hydrocarbyl group of various types like the polyorganosiloxane oils, such as polydimethyl-siloxane, dispersions or emulsions of polyorganosiloxane oils or resins, and combinations of polyorganosiloxane with silica particles wherein the polyorganosiloxane is chemisorbed or fused onto the silica. Silicone suds suppressers are well known in the art and are, for example, disclosed in U.S. Pat. No. 4,265,779, and EP 354 016. Other silicone suds suppressers are disclosed in U.S. Pat. No. 3,455,839 which relates to compositions and processes for defoaming aqueous solutions by incorporating therein small amounts of polydimethylsiloxane fluids. Mixtures of silicone and silanated silica are described, for instance, in German Patent Application DOS 2,124,526. Silicone defoamers and suds controlling agents in granular detergent compositions are disclosed in U.S. Pat. No. 3,933,672 and in U.S. Pat. No. 4,652,392.
- Examples of suitable silicone antifoam compounds are the combinations of polyorganosiloxane with silica particles commercially available from Dow Corning, Wacker Chemie and General Electric.
- Silicone suds suppressors are typically utilized in amounts up to about 2% by weight of the detergent composition, although higher amounts may be used. This upper limit is practical in nature, due primarily to concern with keeping costs minimized and effectiveness of lower amounts for effectively controlling sudsing. Preferably from about 0.01% to about 1% of active silicone suds suppressor is used, more preferably from about 0.05% to about 0.5% by weight of the detergent composition. As used herein, the term “active” excludes water and inactive ingredients (in terms of suds suppression).
- Detergent Composition

- Compositions suitable for use herein comprises from 5% to 70% by weight, preferably from 10% to 60% by weight, more preferably from 20% to 50% by weight, of a certain kind of detersive surfactant component. Such an essential detersive surfactant component must comprise anionic surfactants, nonionic surfactants, or combinations of these two surfactant types.
- Suitable anionic surfactants useful herein can comprise any of the conventional anionic surfactant types typically used in liquid detergent products. These include the alkyl benzene sulfonic acids and their salts as well as alkoxylated or un-alkoxylated alkyl sulfate materials.
- Preferred anionic surfactants are the alkali metal salts of C10-16 alkyl benzene sulfonic acids, preferably C11-14 alkyl benzene sulfonic acids. Preferably the alkyl group is linear and such linear alkyl benzene sulfonates are known as “LAS”. Alkyl benzene sulfonates, and particularly LAS, are well known in the art. Such surfactants and their preparation are described for example in U.S. Pat. Nos. 2,220,099 and 2,477,383. Especially preferred are the sodium and potassium linear straight chain alkylbenzene sulfonates in which the average number of carbon atoms in the alkyl group is from about 11 to 14. Sodium C11-C14, e.g., C12, LAS is especially preferred. Preferably the anionic surfactant comprises at least 50%, more preferably at least 60% and especially 70% by weight of the anionic surfactant of LAS.
- Another preferred type of anionic surfactant comprises ethoxylated alkyl sulfate surfactants. Such materials, also known as alkyl ether sulfates or alkyl polyethoxylate sulfates, are those which correspond to the formula:
-
R′—O—(C2H4O)n—SO3M - wherein R′ is a C8-C20 alkyl group, n is from about 1 to 20, and M is a salt-forming cation. Preferably, R′ is C10-C18 alkyl, n is from about 1 to 15, and M is sodium, potassium, ammonium, alkylammonium, or alkanolammonium. Most preferably, R′ is a C12-C16, n is from about 1 to 6 and M is sodium.
- The alkyl ether sulfates will generally be used in the form of mixtures comprising varying R′ chain lengths and varying degrees of ethoxylation. Frequently such mixtures will inevitably also contain some unethoxylated alkyl sulfate materials, i.e., surfactants of the above ethoxylated alkyl sulfate formula wherein n=0. Unethoxylated alkyl sulfates may also be added separately to the compositions of this invention and used as or in any anionic surfactant component which may be present.
- Preferred unalkoxylated, e.g., unethoxylated, alkyl ether sulfate surfactants are those produced by the sulfation of higher C8-C20 fatty alcohols. Conventional primary alkyl sulfate surfactants have the general formula:

Preferably also the alkoxylated fatty alcohols will be ethoxylated materials that contain from about 2 to 12 ethylene oxide moieties per molecule, more preferably from about 3 to 10 ethylene oxide moieties per molecule.
- The alkoxylated fatty alcohol materials useful in the liquid detergent compositions herein will frequently have a hydrophilic-lipophilic balance (HLB) which ranges from about 3 to 17. More preferably, the HLB of this material will range from about 6 to 15, most preferably from about 8 to 15. Alkoxylated fatty alcohol nonionic surfactants have been marketed under the tradenames Neodol and Dobanol by the Shell Chemical Company.
- Another type of nonionic surfactant which is liquid and which may be utilized in the compositions of this invention comprises the ethylene oxide (EO)—propylene oxide (PO) block polymers. Materials of this type are well known nonionic surfactants which have been marketed under the tradename Pluronic. These materials are formed by adding blocks of ethylene oxide moieties to the ends of polypropylene glycol chains to adjust the surface active properties of the resulting block polymers. EO-PO block polymer nonionics of this type are described in greater detail in Davidsohn and Milwidsky; Synthetic Detergents, 7th Ed.; Longman Scientific and Technical (1987) at pp. 34-36 and pp. 189-191 and in U.S. Pat. Nos. 2,674,619 and 2,677,700.
- Yet another suitable type of nonionic surfactant useful herein comprises the amine oxide surfactants. Amine oxides are materials which are often referred to in the art as “semi-polar” nonionics. Amine oxides have the formula: R(EO)x(PO)y(BO)zN(O)(CH2R′)2.qH2O. In this formula, R is a relatively long-chain hydrocarbyl moiety which can be saturated or unsaturated, linear or branched, and can contain from 8 to 20, preferably from 10 to 16 carbon atoms, and is more preferably C12-C16 primary alkyl. R′ is a short-chain moiety preferably selected from hydrogen, methyl and —CH2OH. When x+y+z is different from 0, EO is ethyleneoxy, PO is propyleneneoxy and BO is butyleneoxy. Amine oxide surfactants are illustrated by C12-14 alkyldimethyl amine oxide.
- In the liquid detergent compositions herein, the essential detersive surfactant component may comprise combinations of anionic and nonionic surfactant materials. When this is the case, the weight ratio of anionic to nonionic will typically range from 100:1 to 1:100, more typically from 20:1 to 1:20.

See soil release agents' definition, p. 278-279, “Liquid Detergents” by Kuo-Yann Lai. For use herein, preferred level of soil release polymer per kilogram of load is from about 0.01 to about 0.8 grams, more preferably the level of polymer is less than 0.2 grams especially from about 0.05 to about 0.15 grams. Contrary to what one would expect higher levels of soil release polymer do not enhance removal. In some cases removal is worse than with lower levels.
