Description

[Technical Field]

[0001] This invention belongs to the field of laundry compositions. In particular, this invention relates to concentrated laundry compositions containing bacterial spores. This invention also relates to a method of washing by diluting a concentrated composition. The compositions and methods of this invention provide sustained reduction and / or prevention of odors in fabrics. [Background technology]

[0002] The problem of fabrics emitting a foul odor even after being washed seems to recur repeatedly.

[0003] One of the objectives of the present invention is to provide a product that improves the unpleasant odor of fabrics.

[0004] Bacterial endospores (hereinafter referred to as "spores") have been reported to provide an odor-preventing effect in laundry compositions. However, this presents the challenge of keeping spores stable and dormant during storage without affecting their ability to germinate and grow after the product has been used. For example, interventions to improve the storage stability of spores carry the risk of delaying subsequent germination and / or growth. One of the objectives of the present invention is to provide a product in which spores are stabilized within the product while germinating quickly when the product is used.

[0005] In some cases, it is desirable to keep the composition in a concentrated form in order to reduce packaging and transportation costs and minimize environmental impact. The concentrate should be stable during storage and should remain stable even when diluted with water of different hardnesses. Therefore, another object of the present invention is to provide a composition that is stable as a concentrate (physical and chemical stability) and does not become unstable when diluted. [Overview of the Initiative] [Means for solving the problem]

[0006] According to a first aspect of the present invention, a concentrated laundry composition is provided. The concentrated laundry composition is dilutable with water to form a liquid laundry detergent composition. The concentrated composition comprises a) 10 to 85% by weight, preferably 22 to 80% by weight of a surfactant, and b) preferably 5 to 20% by weight of a rheology modifier of the composition, and c) about 1×10 2 to about 1×10 9 CFU / g of bacterial spores, and comprises.

[0007] According to second and third aspects of the present invention, there is provided a method of laundering by preparing a detergent that can be used immediately by diluting the concentrated composition of the present invention. The method of the present invention provides for continuous odor removal and / or odor prevention from fabrics over a long period of time.

[0008] The elements of the present invention described in connection with the first aspect of the present invention are accordingly applicable to other aspects of the present invention as well.

BRIEF DESCRIPTION OF THE INVENTION

[0009] The present invention encompasses a concentrated laundry composition that is diluted prior to use. The composition provides a biotics effect, particularly providing long-lasting odor reduction and / or prevention.

[0010] Preferred compositions according to the present invention a) 22 to 80% by weight of a surfactant, and b) 5 to 20% by weight of a rheology modifier, and c) about 1×10 2 to about 1×10 9 CFU / g of bacterial spores, and comprises.

[0012] The present invention also encompasses a method of performing laundry using the concentrated composition of the present invention, the method requiring dilution of the concentrate to produce a dilute detergent for laundry. Preferably, the method includes a step of contacting a fabric with a cleaning liquid, the cleaning liquid containing at least 1×10 2 CFU / liter, preferably about 1×10 2 to about 1×10 8 CFU / liter, preferably about 1×10 4 to about 1×10 7 CFU / liter of bacterial spores, preferably Bacillus spores.

[0013] As used herein, the articles "a" and "an" when used in the claims are understood to mean one or more of what is claimed or described. As used herein, the terms "include", "includes", and "including" are meant to be non-limiting. The compositions of the present disclosure can contain, consist essentially of, or consist of the components of the present disclosure.

[0014] All percentages, ratios, and proportions used herein are, unless otherwise specified, weight % of the composition. All average values are calculated "by weight" of the composition, unless otherwise explicitly indicated. Unless otherwise specified, all ratios are calculated at the weight / weight level.

[0015] Unless otherwise specified, all measurements are performed at 25°C.

[0016] Unless otherwise noted, all concentrations of components or compositions refer to the active portion of that component or composition, excluding impurities that may be present in the commercially available source of such components or compositions, such as residual solvents or by-products.

[0017] composition This disclosure relates to concentrated laundry compositions. In this specification, “concentrated laundry compositions” may also be referred to as “the compositions of the present invention.”

[0018] The composition is in liquid form. The composition may contain about 15% to about 70% by weight of water. The pH of the composition may be optimized to promote the stability of bacterial spores.

[0019] The composition may be in the form of a unitized dosage article, such as a pouch. Such a pouch typically contains a water-soluble film, such as a polyvinyl alcohol water-soluble film, that at least partially encapsulates the composition. A suitable film is available from MonoSol, LLC (Indiana, USA). The composition can be encapsulated in a single-compartment pouch or a multi-compartment pouch. A multi-compartment pouch may have at least two, at least three, or at least four compartments. A multi-compartment pouch may include compartments arranged side by side and / or overlapping. The pouch composition may contain a relatively small amount of water, such as less than about 20% by weight, or less than about 15% by weight, or less than about 12% by weight, or less than about 10% by weight, or less than about 8% by weight of the detergent composition.

[0020] bacterial spores The composition of the present invention is approximately 1 × 10 2 ~Approx. 1×10 9 CFU / g, preferably 1 × 10⁻⁶ 3 ~Approx. 1×10 7 CFU / g, more comfortable 1×10 4 ~Approx. 1×10 7 Contains Bacillus spores at CFU / g.

[0021] The bacterial spores for use herein are i) able to survive the temperatures encountered in the washing process, ii) able to survive on fabric, and iii) capable of secreting enzymes. The spores are capable of germinating and forming cells after the concentrated composition has been diluted and used in the washing process. The spores can be supplied in liquid or solid form. Preferably, the spores are in solid form.

[0022] Some Gram-positive bacteria have a two-stage life cycle, and bacteria growing under certain conditions, such as in response to nutrient deficiency, may undergo an elaborate developmental process leading to spore or endospore formation. Bacterial spores are protected by a coat of about 60 different proteins, assembled as a biochemically complex structure with interesting morphological and mechanical properties. This protein coat is considered a static structure that provides high rigidity and primarily acts as a sieve to filter out large exogenous toxic molecules such as lytic enzymes. Spores play a crucial role in the long-term survival of species because they are highly resistant to extreme environmental conditions. Spores can also remain metabolically dormant for many years. Methods for obtaining bacterial spores from vegetative cells are well known in the field. In some cases, vegetative bacterial cells are grown in liquid medium. From the late logarithmic growth phase or the early stationary growth phase, bacteria may initiate spore formation. Once the bacteria have completed spore formation, their spores can be obtained from the medium, for example, by centrifugation. Various methods can be used to kill or remove any remaining vegetative cells. Spores can be purified from cell debris and / or other materials or substances using various methods. Bacterial spores can be differentiated from vegetative cells, for example, using various techniques such as phase contrast microscopy, automated scanning microscopy, high-resolution nuclear microscopy, or heat-resistant methods.

[0023] Bacterial spores are readily selected and used in commercially available microbial products because they are generally metabolically inactive or dormant, environmentally resistant structures. Despite their robustness and extremely long lifespan, spores can rapidly react to the presence of certain small molecules known as germination-inducing substances, which signal favorable conditions for interrupting their dormant state through germination, the initial stage of the process that completes their life cycle by returning to vegetative bacteria. For example, commercially available microbial products may be designed to disperse spores into an environment where they come into contact with germination-inducing substances present in the environment, allowing them to germinate, become vegetative cells, and perform their intended function. A variety of different bacteria can form spores. Bacteria from any of these groups may be used in the compositions, methods, and kits disclosed herein.For example, the following genera: Astonema, Alkalibacillus, Ammoniphyllus, Amphibacillus, Anaerobacter, Anaerospora, Aneuribacillus, Anoxybacillus, Bacillus, Brevibacillus, Cardanaerobacter, Caloramater, Caminella, Cerasibacillus, Clostridium, Clostridium erythribacter, Cornella, Dendrosporobacter, Desulfotomaculum, Desulfosporomus, Desulfosporosi Nus, Desulfovirgra, Desulfunispora, Desulfurispora, Philifactor, Filovacillus, Geruria, Geobacillus, Geosporobacter, Gracilibacillus, Halonatronum, Heliobacterium, Heliophyllum, Raceella, Lentibacillus, Lysinibacillus, Mahera, Metabacterium, Morela, Natroniela, Oceanobacillus, Orenia, Ornithinibacillus, Oxalophagus, Oxobacter Paenibacillus, Paraliobacillus, Perospora, Perotomaculum, Piscibacillus, Planiphyllum, Ponchibacillus, Propionispora, Salinibacillus, Salsuginibacillus, Seinonella, Shimazuela, Sporasetigenium, Sporoanaerobacter, Sporobacter, Sporobacterium, Sporohalobacter, Sporolactobacillus, Sporomsa, Sporosalthia, Sporotalea, Sporotomaculum, Si Some of the bacteria among *Centrophomonas*, *Syntrophospora*, *Tenuibacillus*, *Tepidibacter*, *Teribacillus*, *Thalassobacillus*, *Thermoacetogenium*, *Thermoactinomyces*, *Thermoalkalibacillus*, *Thermoanaerobacter*, *Thermoanaeromonas*, *Thermobacillus*, *Thermoflavimicrobium*, *Thermovenablum*, *Tuberibacillus*, *Bildibacillus*, and / or *Vulcanobacillus* may form spores.

[0079] Professional ingredients The compositions of this disclosure may include pro-fragrance materials, sometimes referred to as pro-fragrances or fragrance precursors. Pro-fragrance materials typically include covalent bonds between a carrier and one or more perfume raw materials (PRMs). When a spore germinates, it is exposed to enzymes secreted by bacteria, releasing one or more PRMs. Pro-fragrance materials can provide a long-lasting PRM release profile, resulting in the benefit of long-lasting freshness. Furthermore, since the entire amount of PRM is not released at once or is not available separately, the olfactory impact of the PRMs is mitigated. In the compositions of the present invention, such a release profile can reduce what might otherwise be experienced as an intense odor due to relatively high levels of fragrance.

[0080] The pro-fragrance material of the present invention contains PRM. The pro-fragrance material can release PRM when exposed to enzymes released by bacteria.

[0081] The professional fragrance material may gradually release PRM when spores germinate and the bacteria contained within the spores secrete enzymes. Spore germination is not induced during product storage, but only during and after use of the product. Favorable conditions for spore germination are found, for example, while wearing the treated fabric, specifically when the user's body is sweating.

[0082] Pro-fragrance materials for use herein can be selected from the group consisting of glycosides, phosphate esters, amino acid derivatives, and carboxylic acid derivatives, as well as mixtures thereof. Pro-fragrances particularly preferred for use in the compositions and methods of the present invention include glycoside pro-fragrances.
