Description
本発明は、手の保湿用等の用途に好適に用いることができる保湿用水性組成物の改良に関する。 The present invention relates to an improvement of an aqueous composition for moisturizing that can be suitably used for applications such as moisturizing hands.
皮膚や毛髪に対して保湿効果を期待した保湿化粧料は、数多く市販されている。それらのうち、ハンドクリーム等の多くの製品には各種油脂分が基材として配合されており、水仕事等で失われる皮脂の代わりに皮膚のバリア機能を確保したり、皮膚の表面に油脂による保護被膜を形成したりすることにより皮膚表面からの水分の蒸散を抑制することで、保湿機能を発揮している。しかし、このような油性基材を含む保湿化粧料は、塗布後に食品に触ることができないため、炊事等の水仕事が全て終わってからでないと手入れができない欠点があり、家事を行う者にとって、ひび割れや肌荒れの発生を未然に防ぐために利用できないという欠点があった。 Many moisturizing cosmetics that are expected to have a moisturizing effect on the skin and hair are commercially available. Among them, many oils and fats are blended as a base material in many products such as hand creams, ensuring the skin barrier function instead of sebum lost in water work, etc. The moisturizing function is exhibited by suppressing the transpiration of moisture from the skin surface by forming a protective film. However, since moisturizing cosmetics containing such an oily base material cannot touch food after application, there is a drawback that it can not be maintained until after all water work such as cooking is over, for those doing housework, There is a drawback that it cannot be used to prevent the occurrence of cracks and rough skin.
油脂を含まないか、油脂の含有量が小さい水性の保湿化粧料も市販されている。このような保湿化粧料の多くには、優れた保水性および吸水性を有する種々の水溶性多価アルコールが配合されている。しかしながら、これらの水溶性多価アルコールを配合した保湿化粧料は、ベタツキのある重い感触のため使用感や感覚面で好ましくなく、保湿効果の持続性も弱いという欠点があった。 Water-based moisturizing cosmetics that do not contain fats or oils and that contain a small amount of fats and oils are also commercially available. Many of such moisturizing cosmetics contain various water-soluble polyhydric alcohols having excellent water retention and water absorption. However, moisturizing cosmetics blended with these water-soluble polyhydric alcohols have a drawback that they are not preferable in terms of feeling of use and feeling because of the heavy and sticky feel, and the durability of the moisturizing effect is weak.
上記課題の解決策として、水溶性多価アルコールとしてより高分子量のものを用いるものが知られている。例えば、特許文献１には、グリセリンのプロピレンオキサイド付加物を用いる皮膚洗浄料組成物が開示されている。また、特許文献２には、末端水酸基数が４〜１２又は水酸基価から算出した平均重合度２〜１０のポリグリセリンに、アルキレンオキサイド４〜２５モルを付加重合したポリエーテル化合物の１種又は２種以上を、０．１〜３０．０重量％含有する保湿化粧料が開示されている。 As a solution to the above problem, a water-soluble polyhydric alcohol having a higher molecular weight is known. For example, Patent Document 1 discloses a skin cleansing composition using a propylene oxide adduct of glycerin. Patent Document 2 discloses a polyether compound obtained by addition polymerization of 4 to 25 moles of alkylene oxide to polyglycerin having an average degree of polymerization of 2 to 10 calculated from the number of terminal hydroxyl groups of 4 to 12 or a hydroxyl value. A moisturizing cosmetic containing 0.1 to 30.0% by weight of seeds or more is disclosed.
しかしながら、特許文献１記載の皮膚洗浄料組成物は、メーク落とし等を目的とするものであり、保湿を目的とするものではない。また、特許文献２記載の保湿化粧料に含まれるポリエーテル化合物は、経口毒性は低いものの、合成高分子であるため、炊事等の前に肌荒れを予防する目的で使用することについては躊躇われる上、使用者の体質によっては、アレルギーの発症等も懸念される。 However, the skin cleansing composition described in Patent Document 1 is intended for make-up removal and the like, and is not intended for moisture retention. In addition, the polyether compound contained in the moisturizing cosmetic described in Patent Document 2 is a synthetic polymer, although it has low oral toxicity. Therefore, it is praised for use for the purpose of preventing rough skin before cooking. Depending on the constitution of the user, there is a concern about the development of allergies.
本発明は、上記課題に鑑みてなされたものであり、調理等の食品に触れる作業の前にも使用でき、高い安全性と保湿性とを併せ持つ保湿用水性組成物を提供することを目的とする。 The present invention has been made in view of the above problems, and an object thereof is to provide an aqueous composition for moisturizing that can be used even before the operation of touching food such as cooking and has both high safety and moisturizing properties. To do.
本発明は、下記の保湿用水性組成物を提供するものである。
［１］ 水１００重量部に対し、５０〜２００重量部のグリセリンと、１〜１０重量部のカルボキシメチルセルロース塩と、１〜１０重量部の水溶性デンプンまたはその誘導体と、０．００１〜５重量部のクエン酸を含み、カルボキシメチルセルロース塩および水溶性デンプンまたはその誘導体を混合後グリセリンに加え、４０℃以下で加熱処理した後、得られた混合物をクエン酸の水溶液と均一になるまで混合することにより得られる保湿用水性組成物。
［２］ 手の保湿用である上記［１］記載の保湿用水性組成物。
［３］ 前記水溶性デンプンまたはその誘導体が馬鈴薯デンプンである上記［１］または［２］記載の保湿用水性組成物。
The present invention provides the following aqueous composition for moisturizing.
[1] For 100 parts by weight of water, 50 to 200 parts by weight of glycerin, 1 to 10 parts by weight of carboxymethylcellulose salt , 1 to 10 parts by weight of water-soluble starch or derivative thereof, and 0.001 to 5 parts by weight look containing citric acid parts, in addition to carboxymethyl cellulose salt and water-soluble starch or after mixing glycerine derivatives thereof, was heated at 40 ° C. or less, and mixed until an aqueous solution of citric acid and the resulting mixture and uniform The aqueous composition for moisturizing obtained by this .
[2] The aqueous composition for moisturizing according to the above [1], which is for moisturizing hands .
[3] The water-soluble starch or a derivative thereof is potato starch above [1] or [2] Symbol mounting moisturizing aqueous composition.
本発明の保湿用水性組成物は、天然物に由来するカルボキシメチルセルロース塩および水溶性デンプンまたはその誘導体を保湿成分として含み、油脂や合成高分子を含まないため、安全性が高く、食品等に触れる前にも安心して使用できると共に、アレルギーの発症のおそれも低いという利点を有している。 The aqueous composition for moisturizing of the present invention contains carboxymethyl cellulose salt derived from natural products and water-soluble starch or derivatives thereof as a moisturizing component and does not contain fats and oils or synthetic polymers, so it is highly safe and touches foods and the like. It has the advantage that it can be used safely before and has a low risk of developing allergies.
続いて、本発明を具体化した実施の形態につき説明し、本発明の理解に供する。 Subsequently, an embodiment of the present invention will be described to provide an understanding of the present invention.
本発明の一実施の形態に係る保湿用水性組成物（以下、「組成物」と略称する場合がある。）は、水１００重量部に対し、５０〜２００重量部のグリセリンと、１〜１０重量部のカルボキシメチルセルロース塩と、１〜１０重量部の水溶性デンプンまたはその誘導体と、０．００１〜５重量部のクエン酸を含んでいる。 An aqueous composition for moisturizing according to an embodiment of the present invention (hereinafter sometimes abbreviated as “composition”) includes 50 to 200 parts by weight of glycerin and 1 to 10 parts by weight with respect to 100 parts by weight of water. It contains 1 part by weight of carboxymethylcellulose salt , 1 to 10 parts by weight of water-soluble starch or a derivative thereof, and 0.001 to 5 parts by weight of citric acid .
組成物の製造に用いられる水の起源、種類等は、化粧料の製造に使用可能な品質を有する限りにおいて特に制限されないが、蒸留、マイクロフィルターによる滅菌、中空糸膜による精製処理等が行われた精製水が通常用いられる。 The origin and type of water used in the production of the composition is not particularly limited as long as it has quality that can be used in the production of cosmetics. Distillation, sterilization with a microfilter, purification treatment with a hollow fiber membrane, etc. are performed. Purified water is usually used.
組成物の製造に用いられるグリセリンは、化粧料の製造に使用可能な品質を有する限りにおいて、任意の製法により製造されたものを特に制限を受けることなく用いることができる。グリセリンの添加量は、水１００重量部に対し５０〜２００重量部、好ましくは７０〜１５０重量部、より好ましくは１００〜１３０重量部である。グリセリンの添加量が少なすぎると保湿性が低下し、逆に多すぎると組成物の使用感が重くなったりべたついたりする。 As long as it has the quality which can be used for manufacture of cosmetics, what was manufactured by arbitrary manufacturing methods can be used for glycerol used for manufacture of a composition, without receiving a restriction | limiting especially. The addition amount of glycerin is 50 to 200 parts by weight, preferably 70 to 150 parts by weight, and more preferably 100 to 130 parts by weight with respect to 100 parts by weight of water. If the amount of glycerin added is too small, the moisture retention will decrease, while if it is too large, the feeling of use of the composition will become heavy or sticky.
