Description

本発明は水溶性に優れた皮膚洗浄剤に係り、さらに詳しくは、水溶性に非常に優れており、且つ、水道水に含まれている塩素を有効に除去することができる、固形化した皮膚洗浄剤に関する。 The present invention relates to a skin cleanser excellent in water solubility, and more specifically, solidified skin that is very excellent in water solubility and can effectively remove chlorine contained in tap water. It relates to cleaning agents.

一般に、上水源から取水される水道水は、次亜塩素ナトリウムを用いて塩素殺菌を行っており、浄水場での１次塩素処理を通じて殺菌をするとともに有機化合物を除去し、家庭に給水する直前にさらに２次的に塩素を投入して残留塩素を保全維持することにより、病原菌による疾病を予防する。 In general, tap water taken from water sources is sterilized using sodium hypochlorite, and is sterilized through primary chlorination at a water purification plant, and before removing organic compounds and supplying water to households. In order to prevent diseases caused by pathogenic bacteria, the chlorine is further added to the secondary to maintain and maintain the residual chlorine.

しかしながら、上記のように上水源の消毒に用いられる塩素はハロゲン族元素の一種であり、酸化剤、漂白剤、消毒剤などの用途に用いられる有毒性物質として溶存する塩素が有機化合物と反応すれば、環境ホルモンを生成したり、健康や環境に悪影響を招いたりする原因となる。なお、塩素は皮膚や毛髪のたんぱく質を破壊する性質を持っているため、前記塩素が皮膚や毛髪のたんぱく質と反応すれば、皮膚や毛髪を荒らしたり老化させることはもとより、各種の皮膚トラブルの原因となる。 However, as described above, chlorine used for disinfecting water sources is a type of halogen group element, and chlorine dissolved as a toxic substance used in applications such as oxidizing agents, bleaching agents, and disinfecting agents reacts with organic compounds. For example, environmental hormones may be produced, and health and environment may be adversely affected. Since chlorine has the property of destroying skin and hair proteins, if it reacts with skin and hair proteins, it causes skin and hair damage as well as various skin problems. It becomes.

このため、ビタミンＣ１０〜４０重量％、固形剤４０〜６０重量％、溶解剤５〜１０重量％、混練剤５〜１０重量％、発泡剤２〜５重量％、その他の添加剤１〜３重量％の割合にて混合され、固形化して錠剤として製造されるビタミンＣ入浴剤が提案されている（例えば、下記の特許文献１参照）。同文献には、ビタミンＣ入浴剤を水道水に入れて溶解させると、水道水に含まれている残留塩素を完全に除去することができるという記載がある。しかしながら、前記文献に記載の入浴剤は、水道水に含まれている塩素を除去する上で極めて有効であるとはいえ、これを常温の水道水に入れる場合、水への溶解時間が極めて長いといった不都合があった。 For this reason, vitamin C 10-40 wt%, solid agent 40-60 wt%, solubilizer 5-10 wt%, kneading agent 5-10 wt%, foaming agent 2-5 wt%, other additives 1-3 wt% % Vitamin C bathing agent that is mixed and solidified to produce a tablet has been proposed (for example, see Patent Document 1 below). The document describes that residual chlorine contained in tap water can be completely removed by dissolving vitamin C bathing agent in tap water. However, the bathing agent described in the above-mentioned document is extremely effective in removing chlorine contained in tap water, but when it is added to room temperature tap water, the dissolution time in water is extremely long. There was inconvenience.

大韓民国特許出願第２００２−５２９１４号公報Korean Patent Application No. 2002-52914

本発明は上述した問題を解消するためになされたものであり、その目的は、従来の皮膚洗浄剤に比べて水溶性に非常に優れており、且つ、水道水に含まれている塩素を有効に除去することができる、固形化した皮膚洗浄剤を提供することである。 The present invention has been made in order to solve the above-mentioned problems, and its purpose is very excellent in water solubility as compared with a conventional skin cleansing agent, and the chlorine contained in tap water is effective.

以下、この明細書に記載の用語を説明する。 Hereinafter, terms described in this specification will be described.

用語「皮膚洗浄剤」とは、顔または身体を洗うために水に溶解される固形化した（塊状化した）組成物のことをいい、液状、ゲル状またはクリーム状の洗浄剤であり、皮膚に直接的に塗り付けるタイプのものは本発明の皮膚洗浄剤の範囲から除外される。 The term “skin cleanser” refers to a solidified (agglomerated) composition that is dissolved in water to wash the face or body, and is a liquid, gel or cream cleanser. Those that are applied directly to the skin are excluded from the scope of the skin cleanser of the present invention.

本発明の皮膚洗浄剤は、従来の皮膚洗浄剤に比べて水溶性に非常に優れており（水への溶解度が高い）、且つ、水道水に含まれている塩素を有効に除去することができることから、一般需要者にとって使い勝手が極めてよい。なお、その他の添加剤として特定の界面活性剤を混入する場合、水への溶解時間を一層短縮することができる。 The skin cleanser of the present invention is very excellent in water solubility (high solubility in water) compared to conventional skin cleanser, and can effectively remove chlorine contained in tap water. Because it is possible, it is very convenient for general consumers. In addition, when a specific surfactant is mixed as another additive, the dissolution time in water can be further shortened.

本発明の好適な実施の形態による皮膚洗浄剤（洗顔剤）の写真である。3 is a photograph of a skin cleanser (face cleanser) according to a preferred embodiment of the present invention.

以下、本発明を詳述する。 The present invention is described in detail below.

以上述べたように、従来のビタミンＣを含む固形化した皮膚洗浄剤は、水道水に含まれている塩素を除去するのに卓越した効果を有するが、常温下での水への溶解時間があまりにも長過ぎるといった不都合があった。 As described above, the solidified skin cleanser containing vitamin C has an excellent effect in removing chlorine contained in tap water, but the dissolution time in water at room temperature is excellent. There was an inconvenience that it was too long.

従って、本発明の一側面によれば、重炭酸ナトリウム３４〜３９重量％、アスコルビン酸３１〜３５重量％、クエン酸１７〜２１重量％、固形剤８〜１２重量％ 及び残量のその他の添加剤が混合されて固形化した皮膚洗浄剤を提供することにより、上述した問題点を解決した。これにより、従来の皮膚洗浄剤が、２５℃の水を基準として固形化した皮膚洗浄剤３ｇが１分〜２分で溶解されていたのに対し、本発明の一側面による皮膚洗浄剤は、同じ条件下で２６秒以内に溶解されることが分かる（表１参照）。 Thus, according to one aspect of the present invention, sodium bicarbonate 34-39% by weight, ascorbic acid 31-35% by weight, citric acid 17-21% by weight, solid agent 8-12% by weight and other additions of residual amount The problem described above was solved by providing a skin cleansing agent in which the agent was mixed and solidified. As a result, the conventional skin cleanser was dissolved in 1 g to 2 min in 3 g of the skin cleanser solidified based on 25 ° C. water, whereas the skin cleanser according to one aspect of the present invention was It can be seen that it dissolves within 26 seconds under the same conditions (see Table 1).

まず、本発明に含まれている成分のうち重炭酸ナトリウムを説明する。 First, sodium bicarbonate will be described among the components included in the present invention.

本発明において用いられる重炭酸ナトリウムは、発泡剤としての役割を果たすものであり、水に溶けると、二酸化炭素を排出しながら発泡される。このとき、重炭酸ナトリウムは、皮膚洗浄剤に一緒に含まれているアスコルビン酸の水への溶解を早める。また、重炭酸ナトリウムは、それが水に溶ける場合に、顔または肌の皮脂の分泌を促して新陳代謝が活発になるだけではなく、肥満の解消にも大幅に役立つ 。本発明においては、重炭酸ナトリウムの含量を３４〜３９重量％に留める必要がある。もし、重炭酸ナトリウムの含量が３４重量％未満であれば、水への溶解時間が顕著に長引いてしまい、３９重量％を超えると、気泡ばかり多量発生するだけであり、水への溶解時間はむしろ延びるだけではなく、水に溶けながらアルカリ性が濃厚化して後述するアスコルビン酸の弱酸性効果を阻害して皮膚美容に悪い結果を招いてしまうといった問題がある（表１参照）。 Sodium bicarbonate used in the present invention plays a role as a foaming agent, and when dissolved in water, foams while discharging carbon dioxide. At this time, sodium bicarbonate accelerates the dissolution of ascorbic acid contained in the skin cleanser into water. In addition, when sodium bicarbonate dissolves in water, it not only promotes the secretion of sebum in the face or skin and activates metabolism, but also greatly helps to eliminate obesity. In the present invention, it is necessary to keep the content of sodium bicarbonate at 34 to 39% by weight. If the content of sodium bicarbonate is less than 34% by weight, the dissolution time in water will be significantly prolonged. If it exceeds 39% by weight, only a large amount of bubbles will be generated. Rather than just extending, there is a problem that the alkalinity becomes thicker while dissolving in water and the weakly acidic effect of ascorbic acid described later is inhibited, resulting in a bad result for skin cosmetics (see Table 1).

次いで、クエン酸を説明する。 Next, citric acid will be described.

本発明において用いられるクエン酸は、前記重炭酸ナトリウムの発泡を助長する役割を果たし、水に溶ける場合に体内へのカルシウムの吸収を促す役割を果たす。本発明においては、クエン酸の含量を１７〜２１重量％に留める必要がある。もし、クエン酸の含量が１７重量％未満であれば、皮膚洗浄剤の水への溶解時間が著しく延びてしまい、２１重量％を超えると、皮膚洗浄剤の水への溶解時間が変化しなくなる（表１参照）。 Citric acid used in the present invention plays a role of promoting foaming of the sodium bicarbonate, and a role of promoting absorption of calcium into the body when dissolved in water. In the present invention, it is necessary to keep the citric acid content at 17 to 21% by weight. If the citric acid content is less than 17% by weight, the dissolution time of the skin cleanser in water will be remarkably increased, and if it exceeds 21% by weight, the dissolution time of the skin cleanser in water will not change. (See Table 1).

次いで、アスコルビン酸を説明する。 Next, ascorbic acid will be described.

アスコルビン酸は、ビタミンＣとして広く知られているが、水道水に添加すると、下記の反応式１、２の如き反応を経て水道水に含まれている塩素を除去する。 Ascorbic acid is widely known as vitamin C, but when added to tap water, it removes chlorine contained in tap water through reactions such as the following reaction formulas 1 and 2.

［反応式１］
Ｃ６Ｈ８Ｏ６ ＋ ＮａＣｌＯ → Ｃ６Ｈ６Ｏ６ ＋ Ｈ２Ｏ ＋ ＮａＣｌ
（１次殺菌のために投入される次亜塩素酸ナトリウムをビタミンにより除去する反応） [Reaction Formula 1]
C 6 H 8 O 6 + NaClO → C 6 H 6 O 6 + H 2 O + NaCl
(Reaction to remove sodium hypochlorite added for primary sterilization with vitamins)

［反応式２］
Ｃ６Ｈ８Ｏ６ ＋ Ｃｌ２ → Ｃ６Ｈ６Ｏ６ ＋ ２ＨＣｌ
（塩素の維持のために投入される塩素をビタミンにより除去する反応） [Reaction Formula 2]
C 6 H 8 O 6 + Cl 2 → C 6 H 6 O 6 + 2HCl
(Reaction that removes chlorine added to maintain chlorine with vitamins)

前記反応式１、２の反応を経て本発明に含まれているアスコルビン酸が水道水に溶けると、水道水に含まれている塩素が除去される。これにより、残留塩素が肌に及ぼす問題点である皮膚乾燥、皮膚老化、脱毛、ふけ及びアトピーの発生を防止することができる。加えて、アスコルビン酸の自体効能である肌の張りの増加、小皺の予防、再生促進（ビタミンＣはコラーゲンの生成に重要な役割を果たす補助因子であり、肌の張りを増加させ、小皺を予防し、傷の回復を促進させ、レーザー治療後や施術後の修復の一助になる）、毛細血管の抵抗性強化、紅斑治癒（毛細血管の抵抗性を強化して出血を防止することにより、毛細血管の機能が低下している毛細血管拡張症の皮膚や赤くなった（紅斑）皮膚、にきび治療や剥皮後の再生を促進させる）、美白効果（メラニン色素を形成するチロシナーゼを抑制することにより、美白効果が得られ、生成されたメラニンを還元する抗酸化作用によりしみ、そばかすなどの色素沈着を防止したり、又は薄める作用がある）、老化抑制、肌の抵抗力増加（体内の種々の不完全代謝、紫外線などにより生成された有害酸素は肌にシワ、色素沈着などの老化を促進するが、ビタミンＣはこのような有害酸素を除去することにより老化を抑制し、肌の抵抗力を増加させ、肌を健やかに保つ作用をする）などの効果を有する。 When ascorbic acid contained in the present invention is dissolved in tap water through the reactions of the above reaction formulas 1 and 2, chlorine contained in tap water is removed. As a result, it is possible to prevent the occurrence of skin dryness, skin aging, hair loss, dandruff and atopy, which are problems of residual chlorine on the skin. In addition, ascorbic acid itself has the effect of increasing skin tension, preventing wrinkles, promoting regeneration (vitamin C is a cofactor that plays an important role in the production of collagen, increasing skin tension and preventing wrinkles It promotes wound healing, helps repair after laser treatment and treatment, strengthens capillary resistance, and erythema healing (enhances capillary resistance to prevent bleeding, thereby reducing capillary Vasodilatory skin with reduced blood vessel function, reddish (erythema) skin, acne treatment and promoting regeneration after peeling, whitening effect (by suppressing tyrosinase that forms melanin pigment, A whitening effect is obtained. Antioxidant action that reduces the produced melanin has the effect of preventing or fading pigmentation such as freckles, etc., anti-aging, and increased skin resistance (various in the body) Harmful oxygen generated by incomplete metabolism, ultraviolet rays, etc. promotes aging such as wrinkles and pigmentation in the skin, but vitamin C suppresses aging by removing such harmful oxygen and improves skin resistance. To increase the skin and keep the skin healthy).

さらに、反応式２に示すように、塩素の除去時に少量の塩酸が発生するため、水道水を弱酸性化させて肌を健やかに保つだけではなく、皮膚に寄生する毛嚢虫を除去する上で大きな役割を果たす。 Furthermore, as shown in Reaction Formula 2, since a small amount of hydrochloric acid is generated when chlorine is removed, not only the tap water is weakly acidified to keep the skin healthy, but also the hair follicles that parasitize the skin are removed. Play a big role.

一方、本発明に含まれるアスコルビン酸の含量は、３１〜３５重量％に留める必要がある。もし、アスコルビン酸の含量が３１重量％未満であれば、塩素の除去効果が低下し、３５重量％を超える場合には皮膚洗浄剤を固形化させることが困難であるだけではなく、水への溶解時間が長引いてしまうという不都合がある（表１参照）。 On the other hand, the content of ascorbic acid included in the present invention needs to be limited to 31 to 35% by weight. If the content of ascorbic acid is less than 31% by weight, the effect of removing chlorine decreases, and if it exceeds 35% by weight, it is difficult not only to solidify the skin cleanser but also to water. There is a disadvantage that the dissolution time is prolonged (see Table 1).

次いで、固形剤を説明する。 Next, the solid agent will be described.

本発明において用いられる固形剤は、投入されるそれぞれの成分を固体形状（例えば、錠剤）に固めて維持する役割を果たし、水に溶ける場合に皮膚に対して保湿効果及び抗菌・抗酸化効果を与える。本発明においては通常の固形剤が使用可能であるが、好ましくは、ソルビトールまたは乳糖が使用可能であり、より好ましくは、ソルビトールが使用可能である。なお、本発明に含まれる固形剤の含量は８〜１２重量％に留める必要がある。もし、固形剤の含量が８重量％未満であれば、混合粉末を固形化させることが困難であり、１２重量％を超えると、水に溶け難いという問題がある（表１参照）。 The solid agent used in the present invention plays a role of solidifying and maintaining each component to be charged in a solid form (for example, tablet), and has a moisturizing effect and antibacterial / antioxidant effect on the skin when dissolved in water. give. In the present invention, a normal solid agent can be used, but preferably sorbitol or lactose can be used, more preferably sorbitol can be used. In addition, it is necessary to keep the content of the solid agent included in the present invention to 8 to 12% by weight. If the content of the solid agent is less than 8% by weight, it is difficult to solidify the mixed powder, and if it exceeds 12% by weight, it is difficult to dissolve in water (see Table 1).

次いで、その他の添加剤を説明する。 Next, other additives will be described.

本発明において用いられるその他の添加剤としては、洗浄剤または入浴剤に添加する通常の添加剤が使用可能であり、好ましくは、安定剤及び酸化防止剤や、髪を洗ったり入浴や洗顔をするときに水に溶けてほのかな香りを発散したり色を発色するように微量の香料や色素が添加されてもよい。なお、粉末状の混合された皮膚洗浄剤を固形化させるときにプレスにおいて固形化した皮膚洗浄剤の分離を容易にするためにジステアリン酸をさらに含んでいてもよい。 As other additives used in the present invention, usual additives to be added to a detergent or a bathing agent can be used. Preferably, stabilizers and antioxidants, and hair is washed, bathed or washed. Sometimes, a small amount of a fragrance or a pigment may be added so as to dissolve in water and emit a faint scent or develop a color. In order to facilitate separation of the skin cleansing agent solidified in the press when the powdered mixed skin cleansing agent is solidified, it may further contain distearic acid.

一方、本発明に添加されるその他の添加剤は、上述した皮膚洗浄剤の主成分（重炭酸ナトリウム、アスコルビン酸、クエン酸及び固形剤）の添加量が決定された後に残った残量を添加するものであり、例えば、重炭酸ナトリウム３６重量％、アスコルビン酸３３重量％、クエン酸１９重量％及び固形剤１０重量％が混合された場合、その他の添加剤は２重量％が混合されてもよく、重炭酸ナトリウム３９重量％、アスコルビン酸３１重量％、クエン酸１７重量％及び固形剤８重量％が混合された場合にはその他の添加剤は５重量％が混合されてもよい。 On the other hand, the other additives added to the present invention are the remaining amount after the addition amount of the main components (sodium bicarbonate, ascorbic acid, citric acid and solid agent) of the above-mentioned skin cleansing agent is determined. For example, when 36% by weight of sodium bicarbonate, 33% by weight of ascorbic acid, 19% by weight of citric acid and 10% by weight of a solid agent are mixed, other additives may be mixed by 2% by weight. For example, when 39% by weight of sodium bicarbonate, 31% by weight of ascorbic acid, 17% by weight of citric acid and 8% by weight of the solid agent are mixed, 5% by weight of other additives may be mixed.

さらに、本発明の皮膚洗浄剤は、上述した成分の含量をいずれも満足しなければならず、これを満足しない場合には固形化した皮膚洗浄剤が水に溶ける時間が著しく長引いてしまう。これにより、従来の皮膚洗浄剤が、２５℃水を基準として固形化した皮膚洗浄剤３ｇが１分〜２分で溶解されていたのに対し、本発明の一側面による皮膚洗浄剤は、同じ条件下で２６秒以内に溶解されることが分かる（表１参照）。 Furthermore, the skin cleanser of the present invention must satisfy all the above-mentioned components, and if this is not satisfied, the time for the solidified skin cleanser to dissolve in water will be significantly prolonged. As a result, the conventional skin cleanser was dissolved in 1 to 2 minutes in 3 g of the skin cleanser solidified based on 25 ° C. water, whereas the skin cleanser according to one aspect of the present invention is the same. It can be seen that it dissolves within 26 seconds under conditions (see Table 1).

さらに、本発明の他の側面によれば、前記その他の添加剤として、ジメチルドデシルアミンオキシドとソジウムラウリルスルファートとが１：２〜２：１の割合にて混合された混合物を含む場合、皮膚洗浄剤が水に溶ける速度を一層高めることができる。具体的に、ジメチルドデシルアミンオキシドは３次アミンオキシドであって、非イオン性界面活性剤の一種であり、ソジウムラウリルスルファートは陰イオン性界面活性剤の一種であるが、これらを混合して皮膚洗浄剤に添加する場合、２５℃の水を基準として前記固形化した皮膚洗浄剤３ｇが２１秒以内に溶解されることが分かる（表１参照）。なお、前記界面活性剤をそれぞれ別々に添加したり、他の非イオン性界面活性剤と陰イオン性界面活性剤を混合して添加する場合には、溶解速度の向上に対する有意な効果は得られなかった（表１参照）。 Furthermore, according to another aspect of the present invention, the other additive includes a mixture in which dimethyldodecylamine oxide and sodium lauryl sulfate are mixed in a ratio of 1: 2 to 2: 1. The rate at which the skin cleanser dissolves in water can be further increased. Specifically, dimethyldodecylamine oxide is a tertiary amine oxide, which is a kind of nonionic surfactant, and sodium lauryl sulfate is a kind of anionic surfactant. When added to the skin cleanser, 3 g of the solidified skin cleanser is dissolved within 21 seconds based on 25 ° C. water (see Table 1). In addition, when the surfactants are added separately or when other nonionic surfactants and anionic surfactants are mixed and added, a significant effect on improving the dissolution rate is obtained.
