Description

[0001] The present invention relates to a fabric softener article comprising a liquid fabric softener composition filled into a container. [Background technology]

[0002] In the liquid fabric softener sector, products with transparent liquid fabric softeners and their containers are known to enhance the aesthetic value of the product. A known technique for making liquid fabric softeners using silicone compounds as a flexible base transparent involves the combined use of polyether-modified silicone and a water-soluble cationic polymer (Patent Document 1). The use of polyol-based water-soluble solvents is known as a technique to suppress discoloration of containers caused by phenolic fragrances blended into liquid fabric softeners that use cationic surfactants as a softening base (Patent Document 2).

[0004] The inventors discovered that when a liquid fabric softener prepared according to Patent Document 1 was filled into a container and stored, the container's appearance changed color, and furthermore, the inclusion of phenolic fragrances in the liquid fabric softener worsened the discoloration. The inventors found that when the technology described in Patent Document 2 was applied to a liquid fabric softener using a silicone compound as a softening base, the effect of suppressing discoloration of the container was insufficient, and in fact, the liquid fabric softener became cloudy. Therefore, in a fabric softener article comprising a liquid fabric softener containing a phenolic fragrance and a silicone compound filled into a container, the objective was set to suppress discoloration of the container's appearance while maintaining the transparent appearance of the liquid fabric softener.

[0026] Further preferred examples of component (C) include the following solvents: Ethylene glycol monomethyl ether (10.8), 3-methoxy-3-methyl-1-butanol (9.88), ethylene glycol monobutyl ether (10.2), diethylene glycol monobutyl ether (10.0), triethylene glycol monobutyl ether (10.0), ethylene glycol monohexyl ether (9.9), diethylene glycol monohexyl ether (9.7), propylene glycol monomethyl ether (10.0), dipropylene glycol monomethyl ether (9.7), propylene glycol monopropyl ether (9.6), dipropylene glycol monopropyl ether (9.8), dipropylene glycol monobutyl ether (9.6), ethylene glycol monomethyl ether acetate (10.0), ethylene glycol monoethyl ether acetate (9.6)

[0027] (C) Component is a known substance and is readily available on the market or can be prepared.

[0028] (C) Component may be a single type or multiple types may be used in combination.

[0029] The content of component (C) is preferably 0.5 to 20% by mass, more preferably 1 to 15% by mass, even more preferably 3 to 10% by mass, and particularly preferably 5 to 10% by mass, based on the total mass of the liquid fabric softener composition. When the content of component (C) is 0.5% by mass or more, excellent blending effects can be obtained. When the content of component (C) is 20% by mass or less, the influence of solvent-derived odors on the fragrance of component (A) can be suppressed.

[0030] Although this invention is not limited by any particular theory, the relationship between components (A) to (C) and the suppression of container discoloration is considered to be as follows. The discoloration of the container occurs when the phenolic fragrance (component (A)) penetrates and / or adsorbs into the nylon-containing layer that makes up the container and reacts with the nylon. The polyether-modified silicone (component (B)) promotes the aforementioned penetration and / or adsorption, worsening the discoloration. Solvents with an SP value of 8 to 13 (component (C)) have high compatibility (affinity) with components (A) and (B), so both components dissolve sufficiently in component (C). By combining component (C) with components (A) and (B) in a predetermined blending ratio according to the present invention, the amount of phenolic fragrance that reacts with nylon is suppressed, and discoloration is inhibited.

[0031] [Mass ratio of component (A) to component (B)] The mass ratio (A / B) of component (A) to component (B) is 0.1 to 10, preferably 0.1 to 2.0, and more preferably 0.5 to 1.5. Within this mass ratio range, the purpose of incorporating component (A) can be achieved while maintaining the transparent appearance of the liquid softener.

[0032] [Mass ratio of component (A) to component (C)] The mass ratio (A / C) of component (A) to component (C) is 0.01 to 0.5, preferably 0.02 to 0.3, and more preferably 0.05 to 0.2. Within this mass ratio range, the purpose of incorporating component (A) can be achieved while suppressing discoloration of the container.

[0033] [Mass ratio of component (B) to component (C)] The mass ratio (B / C) of component (B) to component (C) is 0.01 to 1, preferably 0.05 to 0.8, and more preferably 0.05 to 0.5. Within this mass ratio range, the purpose of incorporating component (B) can be achieved while maintaining the transparent appearance of the liquid softener.

[0034] [Optional ingredients] Within the limits that do not impair the effects of the present invention, components other than components (A) to (C) that are commonly used in liquid fabric softeners may be optionally added. Examples of optional components are described below.

[0035] [Component (D): Water-soluble cationic polymer] Component (D) is primarily added to enhance the flexibility of textile products. Furthermore, component (D) also has the effect of increasing the adsorption of components (A) and (B) to textile products.

[0036] (D) Component is water-soluble. "Water-soluble" means that the solution obtained by adding 1 g of the test substance to 100 g of water at 25°C is colorless and transparent. Component (D) is cationic when dissolved in water. Component (D) preferably has a cationization degree of 0.1% or more (e.g., 0.1 to 35%), and more preferably 2.5% or more (e.g., 2.5 to 15%), as described later. When the cationization degree is within the above range, the adsorption of the coexisting component (B) to the textile product can be further enhanced, and the cost increase due to excessive formulation can be prevented.

[0037] If component (D) is (i) a polymer of cationic monomers, (ii) a copolymer of cationic monomers and nonionic monomers, or (iii) a nonionic polymer in which a portion is modified or substituted with cationic groups (such as cationized cellulose), the degree of cationization is defined as the value calculated by the following formula (1). Degree of cationization (%) = X × Y × 100 Equation (1) [X: Atomic weight of cationized atoms (such as nitrogen) in the cationic group of the polymer] Y: Number of moles of cationic groups contained in 1g of polymer.

[0038] If component (D) is (i) a copolymer of a cationic monomer and an anionic monomer, or (ii) a copolymer of a cationic monomer, anionic monomer and a nonionic monomer, the degree of cationization is defined as the value calculated by the following formula (2). Degree of cationization (%) = X × (YZ) × 100 Equation (2) [X: Atomic weight of cationized atoms (such as nitrogen) in the cationic group of the polymer] Y: Number of moles of cationic groups contained in 1g of polymer Z: Number of moles of anionic groups contained in 1 g of the polymer (Examples of the anionic groups in Z include carboxyl groups and sulfonic acid groups contained in monomer units in the polymer chain (for example, the carboxylic acid group in acrylic acid). However, counterions of cationic groups are not included.)

[0039] As an example, the calculation procedure for the degree of cationization of MERQUAT 280 (mass ratio of dimethyldiallylammonium chloride to acrylic acid = 80:20. In formula (III), m:n = 65:35) (manufactured by Nippon Lubrizol Corporation), which is a copolymer of a cationic monomer and an anionic monomer, is shown.

[0040] [Chemical formula]

[0041] X: 14 (atomic weight of nitrogen atom) Y: 4.95×10 -3 (Weight of 1 g of cationic groups: 0.8 g, calculated from the molecular weight of the cationic groups) Z: 2.78×10 -3 (Weight of 1 g of anionic groups: 0.2 g, calculated from the molecular weight of the anionic groups) From formula (2), the degree of cationization (%) = 14×(4.95×10 -3 -2.78×10 -3 )×100 = 3.0

[0042] According to the above calculation method, the degree of cationization of a polymer of a nonionic monomer or a polymer of an anionic monomer is 0.

[0043] When the weight average molecular weight of component (D) is measured by gel permeation chromatography using polyethylene glycol as a standard substance, it is preferably 1,000 to 5,000,000, more preferably 3,000 to 1,000,000, and even more preferably 5,000 to 500,000. Within the aforementioned weight-average molecular weight range, the adsorption of component (B) to textile products is enhanced, and the increase in viscosity of the liquid softener composition is suppressed, resulting in excellent usability.

[0044] Component (D) can be any of the aforementioned water-soluble and cationic polymers without particular limitation, but preferably it is a water-soluble polymer having one or more cationic groups selected from amino groups, amine groups, and quaternary ammonium groups. Examples of component (D) include: MERQUAT100 (manufactured by Lubrizol Japan), Adeka Cathioace PD-50 (Adeka Corporation), Daidoll EC (manufactured by Daido Chemical Industries, Ltd.), and other polymers of dimethyldiallylammonium chloride. Dimethyldiallylammonium chloride / acrylamide copolymer such as MERQUAT550 JL5 (manufactured by Lubrizol Japan Co., Ltd.), Dimethyldiallylammonium chloride / acrylic acid copolymer such as MERQUAT280 (manufactured by Lubrizol Japan Co., Ltd.) Cationic cellulose such as Leoguard KGP (manufactured by Lion Corporation), Imidazolinium chloride / vinylpyrrolidone copolymer such as LUVIQUAT-FC905 (manufactured by BASF), Polyethyleneimine such as LUGALVAN-G15000 (manufactured by BASF), Cationic polyvinyl alcohol such as POVAL CM318 (manufactured by Kuraray Co., Ltd.) Natural polymer derivatives containing amino groups such as chitosan, Examples include copolymers with vinyl monomers having hydrophilic groups to which diethylamino methacrylate ethylene oxide or the like has been added.

The content of component (G) is not particularly limited as long as the purpose of formulation is achieved, but is preferably 0.0001 to 1% by mass relative to the total mass of the liquid softener composition.

[0062] 〔water〕 The liquid fabric softener composition is preferably an aqueous composition containing water. For the water used, tap water, purified water, deionized water, distilled water, or ion-exchanged water can be used. Of these, ion-exchanged water is preferable. The water content is not particularly limited, but is preferably 60 to 95% by mass, and more preferably 70 to 90% by mass, relative to the total mass of the liquid softener composition.

[0063] [Method for manufacturing liquid fabric softener composition] Liquid fabric softener compositions can be manufactured by known methods, for example, by following the same process as for liquid fabric softener compositions mainly composed of polyether-modified silicone. For example, a liquid fabric softener composition can be produced by mixing an oil phase containing components (A), (B), and (C) with water and stirring the mixture.

[0064] [How to use liquid fabric softener composition] The method for treating textile products using the liquid fabric softener composition is not particularly limited and can be used in the same way as conventional liquid fabric softeners. For example, the liquid fabric softener composition can be dissolved in the rinse water during the rinsing stage of washing, or the liquid fabric softener composition can be dissolved in water in a container such as a basin, and the textile products can then be immersed in the solution. In either case, the solution should be diluted to an appropriate concentration before use, but the bath ratio (weight ratio of the treatment solution to the textile products) is preferably 3 to 100 times, and particularly preferably 5 to 50 times. The types of textile products that can be treated with the liquid fabric softener composition are not particularly limited and include, for example, clothing, curtains, sofas, carpets, towels, handkerchiefs, sheets, and pillowcases. The materials may also be natural fibers such as cotton, silk, and wool, or synthetic fibers such as polyester.

[0065] 〔container〕 The liquid fabric softener composition is filled into a container to constitute a fabric softener article. The shape of the container is not particularly limited, but examples include a bag shape (for refills). The bag-shaped container may be, for example, one described in paragraphs

[0019] to

[0022] of Japanese Patent Publication No. 2001-098300, or a standing pouch having the structure described in Figure 3 of Japanese Patent Publication No. Hei 8-26297.

[0066] The container is made of laminated material. An example of laminated material is one that consists of an outermost layer made of nylon (the layer to which light from the outside first enters; also called the base layer) and an inner layer made of polyethylene (the layer that comes into contact with the liquid softener composition; also called the adhesive layer). Examples of nylon include stretched nylon (ONy). From the viewpoint of suppressing discoloration of the container's appearance, nylon with fewer terminal amide groups and terminal amino groups is preferred. Examples of polyethylene include linear low-density polyethylene (L-LDPE) and low-density polyethylene (LDPE).

[0067] At least a portion of the laminated material is a transparent or translucent nylon-containing layer. In transparent or translucent nylon-containing layers, discoloration due to phenolic fragrances is easily apparent, but the liquid fabric softener composition according to the present invention can suppress such discoloration. Preferably, the nylon-containing layer constitutes the base layer. The nylon-containing layer may be entirely transparent or translucent. That is, the entire base layer may be a transparent or translucent nylon-containing layer. Transparent means that the transmittance in the visible light region (660 nm) is 60% or higher, while semi-transparent means that the transmittance in the visible light region (660 nm) is 40% or higher but less than 60%. Transmittance can be measured with a spectrophotometer.

[0068] The following describes the laminated materials that make up the bag-shaped container. The thickness of the base material layer can be appropriately determined considering bag-making processability, cost, strength, and rigidity. The thickness of the base material layer is not particularly limited as long as it maintains the minimum necessary rigidity, but from the viewpoint of suppressing discoloration of appearance, it is preferably 10 to 50 μm, more preferably 10 to 30 μm, and most preferably 10 to 20 μm. The overall thickness of the laminated material can be appropriately determined considering bag-making processability, cost, strength, and rigidity, and is preferably 100 to 300 μm.

[0069] The laminated material may further include layers different from the base layer and the adhesive layer, such as an aluminum-deposited plastic layer, an aluminum layer, or a PET (polyethylene terephthalate) layer. Examples of aluminum-deposited plastic layers and aluminum layers include those described in Japanese Patent Publication No. 2010-222711. The aluminum-deposited plastic layer and the aluminum layer can be arranged to cover the base layer and the adhesive layer, but in the present invention, from a cost viewpoint, they are arranged to cover a portion of the base layer and / or the adhesive layer. The aluminum-deposited plastic layer and the aluminum layer do not allow phenolic fragrances that cause discoloration of the nylon-containing layer to pass through, but discoloration in the parts not covered by these layers can be suppressed in the liquid softener composition according to the present invention.

[0070] The lamination of each layer can be carried out using adhesives such as polyurethane-based or ester-based adhesives, or water-soluble adhesives such as casein. Bag-shaped containers can be manufactured by overlapping film-like laminated materials with the innermost layer facing inward, and then bonding the edges together using heat sealing or the like to form a bag. [Examples]

[0078] [(G) Ingredient: Preservative] The following G-1 was used. G-1: 1,2-Benzisothiazolin-3-one (Manufactured by Clariant Japan Co., Ltd. Product name: "NIPACIDE BIT 20")

[0079] [Preparation of liquid fabric softener composition] First, components (A), (B), (C), and (E) were placed in a 1000 ml beaker and thoroughly stirred using a stirring blade to obtain an oil phase mixture. On the other hand, component (D) was dissolved in deionized water to obtain an aqueous phase mixture. Next, while stirring the oil phase mixture, the aqueous phase mixture was added, followed by the addition of components (F) and (G), and the mixture was thoroughly stirred until homogeneous to prepare 1000 g of liquid softener composition. The composition of each liquid fabric softener composition is shown in Table 2 below. The content values ​​in Table 2 represent the content (mass %) relative to the total mass of the liquid fabric softener composition. In Table 2, "A / B" indicates the mass ratio of component (A) to component (B). In Table 2, "A / C" indicates the mass ratio of component (A) to component (C). In Table 2, "A / D" indicates the mass ratio of component (A) to component (D). In Table 2, "B / C" indicates the mass ratio of component (B) to component (C).

[0080] [Evaluation of the appearance (transparency) of liquid fabric softener composition immediately after manufacturing] For each liquid fabric softener composition in the examples and comparative examples, when the liquid fabric softener composition was placed in a measurement cell (a glass cell with an optical path length of 10 mm) and deionized water was placed in a control cell, the light transmittance at a wavelength of 660 nm was 95% or higher. Therefore, each liquid fabric softener composition in the examples and comparative examples was transparent.

[0081] 〔container〕 A standing pouch having the structure described in Figure 3 of Japanese Patent Publication No. 8-26297 was used. The standing pouch was molded from a bag-like container (height: 260 mm; width at the top and bottom ends: 130 mm; bottom surface: spindle-shaped with a cross-sectional area parallel to the axis (long axis: 100 mm; short axis: 60 mm)). The bag-shaped container was made of a laminated material consisting of an adhesive layer (inner layer) laminated on top of a base layer (outer layer). The base layer was a flexible film (15 μm thick) made of stretched nylon (ONy). The adhesive layer was a flexible film made of linear low-density polyethylene (L-LDPE) with a thickness of 150 μm.

[0082] [Evaluation of container appearance (transparency)] The transmittance of a pouch-shaped container cut to 4 mm x 2.5 mm was measured in the visible light region at 660 nm using a UV-2450 ultraviolet-visible spectrophotometer manufactured by Shimadzu Corporation, and the result was 70% or higher. Since no printing was applied to the pouch-shaped container, the standing pouches used in the examples and comparative examples were transparent throughout. The transmittance of the substrate layer alone, measured in the same manner as described above, was also 70% or higher. Therefore, at least a portion of the laminated material constituting the standing pouch was a transparent nylon-containing layer.

[0083] [Evaluation of container appearance] A sample of fabric softener was prepared by filling a standing pouch with a liquid fabric softener composition and sealing it. This sample was stored in a constant temperature room at 50°C for 30 days. The changes in the appearance of the container due to storage were visually evaluated according to the following criteria.

[0084] [Visual evaluation of liquid fabric softener compositions] Liquid fabric softener compositions were placed in glass containers, sealed tightly, and stored at 40°C for one month. The changes in the appearance of the liquid fabric softener compositions during storage were visually evaluated according to the following criteria. The average scores (rounded to the nearest whole number) of the panelists (10 people) are shown in the "Appearance Evaluation of Liquid Contents" column of Table 2. A score of 3 or higher was considered acceptable. <Evaluation Criteria> 4: No change (turbidity) compared to the sample before storage. 3: There was a slight change (turbidity) compared to the sample before storage. 2: The sample changed (became cloudy) compared to the sample before storage. 1: Significant changes (cloudiness, separation) were observed compared to the sample before storage.

[0085] [Evaluation of lingering fragrance] 1. Softening treatment of evaluation fabric 1-1. Pretreatment A commercially available cotton towel (manufactured by Toshinsha) was used as the evaluation cloth. The evaluation cloth was subjected to the following pretreatment three times using a commercially available detergent "Top Platinum Clear" (manufactured by Lion Corporation) and a twin-tub washing machine (Toshiba VH-30S). Pretreatment: Wash with standard detergent amount, 30 times the bath ratio, 45°C tap water (10 minutes), followed by rinsing with water (10 minutes), repeating this cycle twice. 1-2. Flexibility treatment A pre-treated evaluation cloth (1.0 kg) was washed using a twin-tub washing machine (Toshiba VH-30S) and commercially available detergent "Top Platinum Clear" (Lion Corporation) for 10 minutes (standard usage amount, standard course, bath ratio 30 times, using 25°C tap water). Subsequently, a first rinse (3 minutes), spin-drying, and a second rinse (3 minutes) were performed. At the start of the second rinse, each liquid fabric softener composition was added for softening treatment (3 minutes, 6.67 ml of fabric softener used, bath ratio 20 times, using 25°C tap water). After the softening treatment, the cloth was spin-dried (1 minute), and the evaluation cloth removed from the twin-tub washing machine was dried (18 hours) under constant temperature and humidity conditions (20°C, 40% RH). 2.
