Description

Technical Field

[0001] The present invention is in the field of laundry detergent compositions. In particular, the present invention relates to concentrated laundry detergent compositions comprising bacterial spores. The present invention also relates to methods for laundry washing by diluting the concentrated compositions. The compositions and methods of the present invention provide a sustained reduction and / or prevention of malodors on fabrics. Background Art

[0002] Bad odors on fabrics even after they have been washed seem to be a recurring problem.

[0003] One of the objects of the present invention is to provide a product for improving malodor of fabrics.

[0004] Bacterial endospores (hereinafter "spores") have been reported to provide anti-malodor benefits in laundry detergent compositions. However, this presents the challenge of keeping the spores stable and dormant upon storage without affecting their ability to germinate and grow after use of the product. For example, interventions to improve the storage stability of the spores carry the risk that they will slow subsequent germination and / or growth. One of the objects of the present invention is to provide a product in which the spores are stable in the product but germinate rapidly when the product is used.

[0005] It is sometimes desirable to have a composition in concentrated form to reduce packaging and transportation costs and to reduce environmental impact. The concentrate should be stable when stored and should also be stable when diluted in water of varying hardness. Therefore, another object of the present invention is to provide a composition that is stable (physical and chemical stability) as a concentrate and does not become unstable when diluted. Summary of the invention

[0006] According to a first aspect of the present invention, there is provided a concentrated laundry detergent composition. The concentrated laundry detergent composition can be diluted in water to form a liquid laundry detergent composition. The concentrated composition comprises:

[0007] a) 10 to 85 wt %, preferably 22 to 80 wt %, of a surfactant;

[0008] b) a rheology modifier, preferably from 5% to 20% by weight of the composition; and

[0009] c) Approximately 1×10 2 CFU / g is about 1×10 9 Composition of CFU / g bacterial spores.

[0010] According to the second and third aspects of the present invention, there is provided a method for washing clothes by diluting the concentrated composition of the present invention to prepare a ready-to-use detergent. The method of the present invention continuously removes malodors from fabrics and / or continuously prevents malodors from appearing on fabrics over an extended period of time.

[0011] Elements of the invention described with respect to the first aspect of the invention apply mutatis mutandis to the other aspects of the invention. DETAILED DESCRIPTION

[0026] Composition

[0027] The present disclosure relates to concentrated laundry detergent compositions."Concentrated laundry detergent compositions" are sometimes referred to herein as "compositions of the present invention."

[0028] The composition is in liquid form. The composition may comprise from about 15% to about 70% water by weight of the composition. The pH of the composition may be optimized to favor bacterial spore stability.

[0029] The composition can be in the form of a combined dose article such as a pouch. Such pouches typically include a water-soluble film, such as a polyvinyl alcohol water-soluble film, which at least partially encapsulates the composition. Suitable films are available from MonoSol, LLC (Indiana, USA). The composition can be encapsulated in a single compartment pouch or a multi-compartment pouch. The multi-compartment pouch can have at least two, at least three or at least four compartments. The multi-compartment pouch can include compartments that are arranged side by side and / or stacked. The bagged composition can have a relatively small amount of water, for example, less than about 20%, or less than about 15%, or less than about 12%, or less than about 10%, or less than about 8% water by weight of the detergent composition.

[0030] Bacterial spores

[0031] The composition of the present invention comprises about 1×10 2 CFU / g is about 1×10 9 CFU / g, preferably 1×10 3 CFU / g is about 1×10 7 CFU / g and more preferably 1×104 CFU / g is about 1×10 7 CFU / g of composition Bacillus spores.

[0032] Bacterial spores for use herein: i) are capable of surviving at temperatures present in a laundry washing process; ii) have fabric affinity; and iii) have the ability to secrete enzymes. After the concentrated composition is diluted and used in a laundry washing process, the spores have the ability to germinate and form cells. The spores can be delivered in liquid or solid form. Preferably, the spores are in solid form.

[0033] Some Gram-positive bacteria have a two-stage life cycle, in which under certain conditions, such as growth in response to nutrient deprivation, bacteria can undergo a complex developmental program that leads to spore or endospore formation. Bacterial spores are protected by an outer shell assembled from about 60 different proteins, which are assembled into a biochemically complex structure with an opaque morphology and mechanical properties. The protein shell is considered to provide rigidity and mainly acts as a sieve to exclude static structures of exogenous large toxic molecules (such as lyases). Spores play a key role in the long-term survival of strains because they are highly resistant to extreme environmental conditions. Spores can also maintain metabolic dormancy for several years. Methods for obtaining bacterial spores from vegetative cells are well known in the art. In some examples, vegetative bacterial cells are grown in liquid culture medium. From the late logarithmic growth stage or the early static growth stage, bacteria can begin to sporulate. When bacteria have completed sporulation, spores can be obtained from culture medium by, for example, using centrifugation. Various methods can be used to kill or remove any remaining vegetative cells. Various methods can be used to purify spores from cell debris and / or other materials or substances. For example, bacterial spores can be distinguished from vegetative cells using various techniques such as phase contrast microscopy, automated scanning microscopy, high resolution atomic force microscopy, or tolerance to heat.

[0034] Because bacterial spores are usually metabolically inert or dormant environmentally tolerant structures, they are easily selected for use in commercial microbial products. Despite their robustness and extreme lifespan, spores can quickly respond to the presence of small specific molecules known as germination agents, which send signals of favorable conditions for releasing dormancy by germination (the initial step in the process of completing the life cycle by returning to vegetative bacteria). For example, commercial microbial products can be designed to be dispersed into an environment where spores encounter germination agents present in the environment to germinate into vegetative cells and perform the desired function. A variety of different bacteria can form spores. Bacteria from any of these groups can be used in the compositions, methods and kits disclosed herein.
