Description

Technical Field

[0001] The present invention relates to an aqueous cleaning composition containing a crushed product of Sargassum fulvellum polysaccharide, etc.

Background Art

[0002] Cleaning compositions are for removing sebum and makeup dirt, and oily ones such as oil-based types mainly composed of oil agents and aqueous ones such as lotion-based types containing water and surfactants are used.

[0003] Aqueous cleaning compositions are preferred in terms of usability such as having less stickiness compared to oily ones, but may have insufficient detergency compared to oily ones. Therefore, a cleaning composition with excellent detergency is required.

[0004] On the other hand, cosmetics containing Sargassum fulvellum polysaccharide as a stabilizer, etc. have been reported (for example, see Patent Document 1), but no improvement in the detergency of cleaning compositions by Sargassum fulvellum polysaccharide or investigation of physical properties for that purpose has been made.

[Figure 2] The photo shows the evaluation results of the emulsifying properties of the aqueous compositions of the examples and comparative examples in Test 2 with respect to oleic acid, which is considered to be sebum. [Modes for carrying out the invention]

[0011] The present invention will be described below. <Aqueous cleaning composition> The present invention relates to an aqueous washing composition containing a powdered Suizenji-nori polysaccharide, wherein the Suizenji-nori polysaccharide powder is obtained by adding a 1% by mass aqueous dispersion of the Suizenji-nori polysaccharide powder and oleic acid in a 20:10 (by mass ratio) ratio to a vial, shaking it up and down 100 times, and after standing for 30 minutes, maintaining a uniform single layer (hereinafter sometimes referred to as "the composition of the present invention").

[0012] The inventors conducted various studies in search of an aqueous cleaning composition that exhibits excellent cleaning power. In this context, the inventors succeeded in creating a composition with excellent cleaning power by crushing Suizenji-nori polysaccharide and incorporating it into an aqueous cleaning composition. Based on this finding, the present invention was completed.

[0013] ≪Powdered Suizenji Nori Polysaccharide≫ The composition of the present invention contains pulverized Suizenji Nori polysaccharide. Specifically, Sacran is an example of Suizenji Nori polysaccharide. Sacran is a type of sulfated polysaccharide with a molecular weight of 2,000,000 or more and a CAS registry number of 1039552-36-7. Specifically, Sacran has a repeating structure of sugar chain units in which sugar structures having a hexose structure and sugar structures having a pentose structure are linked in a linear or branched chain by α-glycosidic bonds or β-glycosidic bonds, and contains sulfated sugars in which the sugar chain units are lactated as sugar structures, and in the sugar chain units, 2.7 or more hydroxyl groups per 100 hydroxyl groups are sulfated, or sulfur element accounts for 1.5% by mass or more of the total elements.

[0014] Sacran is known to be obtained by protonating and partially hydrolyzing polysaccharides extracted from Suizenji-nori, a species endemic to Japan. It is possible to use a product prepared in this way, or to use a commercially available product.

[0015] The present invention is characterized by using a pulverized product of Ecklonia cava polysaccharide. The pulverized Ecklonia cava polysaccharide is pulverized by a high shearing force, so that the network structure of the polysaccharide in the aqueous cleaning composition becomes dense, and it is considered that excellent affinity with sebum can be exhibited. Here, the pulverized Ecklonia cava polysaccharide used in the aqueous cleaning composition of the present invention, which has a dense network structure of polysaccharide and excellent affinity with sebum, is defined as a product that maintains a uniform single layer after adding a 1% by mass aqueous dispersion of the pulverized Ecklonia cava polysaccharide and oleic acid in a ratio of 20:10 (mass ratio) into a vial, shaking it up and down 100 times, and allowing it to stand for 30 minutes. Here, "maintaining a uniform single layer" means that there is no obvious separation as confirmed visually. The properties of the pulverized Ecklonia cava polysaccharide are not limited, but for example, it may be a dispersion liquid dispersed in a medium containing water or a hydrophilic organic solvent as a dispersion medium for water and polysaccharide.

Except for incorporating the above-mentioned Suizenji-nori polysaccharide pulverized material into the aqueous cleaning composition, the aqueous cleaning composition can be produced according to conventional methods.

[0054] Furthermore, all matters described in the above section on <Aqueous Washing Composition>, including the type, amount, and grinding treatment of Suizenji Nori polysaccharide, apply to the description of the <Manufacturing Method>. [Examples]

[0055] The present invention will be specifically described below with reference to examples, but these are merely illustrative examples of the present invention, and the scope of the present invention is not limited thereto.

[0056] [Test 1] <Preparation of aqueous composition> The aqueous compositions of the present invention were prepared according to the formulations in Table 1. Specifically, a 1% aqueous dispersion (A) of Suizenji Nori polysaccharide (Sacran®; Green Science Material Co., Ltd.) and other water-soluble polymers was mixed with a disperser mixer (TKROBOMICS; PRIMI The samples were fabricated using either a shear condition of 5000 rpm x 10 minutes (X Company) or 21500 rpm x 10 minutes (Cleamix (CLM-0.8S; M TECHNIQUE Co.)).

[0057] <Rating> The cleaning properties of the aqueous composition of the present invention were evaluated based on its emulsifying ability with respect to oleic acid, which is considered to be sebum. Fill a vial (SV50) with (A) a 1% aqueous dispersion of the above water-soluble polymer and (B) oleic acid (NAA400; NOF Corporation) in a ratio of 20g:10g. Shake the vial up and down 100 times and let it stand for 30 minutes. I took an exterior photo a few minutes later. We evaluated the samples by visually checking for any separation of layers, assigning a circle (○) if no separation occurred and a cross (×) if separation was present.

[0058] [Table 1]

[0059] <Result> The evaluation results are shown in Figure 1. The composition in the example maintained a uniform layer after 30 minutes and exhibited excellent emulsification properties with respect to oleic acid, which is considered to be sebum. In other words, it is considered to have excellent cleansing properties. On the other hand, in Comparative Example 1, where Disper treatment was performed instead of Clearmix treatment, layer separation was observed, and the emulsification of oleic acid, which was considered to be sebum, was insufficient. Furthermore, in Comparative Examples 2-7, which used water-soluble polymers other than Suizenji Nori polysaccharide, layer separation was observed regardless of whether the treatment was Clearmix or Disper, indicating insufficient emulsification with respect to oleic acid, which was considered to be sebum.

[0060] [Exam 2] <Preparation of aqueous composition> The aqueous composition of the present invention was prepared according to the formulation in Table 2. Specifically, a 1% aqueous dispersion of Suizenji-nori polysaccharide (A) was prepared in the same manner as in Test 1 using Clearmix. (A) The above 1% aqueous dispersion of Suizenji-nori polysaccharide and (B) the other components were stirred and mixed to prepare the aqueous composition of the present invention. did.

[0061] <Rating> The cleaning properties of the aqueous composition of the present invention were evaluated based on its emulsifying ability with respect to oleic acid, which is considered to be sebum. The aqueous composition of the present invention (A) + (B):(C) oleic acid (NAA400; NOF Corporation) was filled into a vial (SV50) in a ratio of 20g:10g, shaken up and down 100 times, allowed to stand for 30 minutes, and then photographed. We evaluated the samples by visually checking for any separation of layers, assigning a circle (○) if no separation occurred and a cross (×) if separation was present. Furthermore, observations were made using a microscope (all-in-one fluorescence microscope BZ-X810; Keyence Corporation) at 400x brightfield magnification.

[0062] [Table 2]

[0063] <Result> The evaluation results are shown in Figure 2. The composition of Example 2, which contained pulverized Suizenji Nori polysaccharide treated with Clearmix, maintained a uniform single layer after 30 minutes and exhibited excellent emulsification properties with respect to oleic acid, which is considered to be sebum. Furthermore, fine emulsified particles were observed under a microscope, indicating excellent emulsification properties. In other words, it is considered to have excellent cleaning properties. On the other hand, Comparative Example 8, which did not contain Suizenji Nori polysaccharide, showed layer separation and insufficient emulsification with respect to oleic acid, which was considered to be sebum. Furthermore, microscopic observation revealed coarse emulsified particles, indicating insufficient emulsification. Furthermore, when the foaming performance was tested, Example 2 showed good dispensing performance, similar to Comparative Example 8, which did not contain Suizenji Nori polysaccharide.

[0064] As described above, the pulverized Suizenji Nori polysaccharide (Cleamix) is incorporated into the aqueous washing composition. It was found that this makes it possible to create a composition with excellent cleansing power for sebum and other substances. [Industrial applicability]

[0065] This invention can be applied to topical skin preparations, pharmaceuticals, cosmetics including quasi-drugs, and the like.
