Abstract
Description
本発明は、浴湯に投入した際に自己乳化する浴用剤組成物に関する。 The present invention relates to a bath agent composition that self-emulsifies when put into bath water.
浴湯に投入した際に自己乳化することにより白濁する自己乳化型浴用剤として、種々の界面活性剤と油性成分を組み合わせたものが提案されている（特許文献１〜４）。これら自己乳化型の浴用剤に配合される代表的な油性成分は、流動パラフィンに代表される常温で液体の飽和炭化水素類である。液体の炭化水素油は、肌にしっとり感を与えるものであるが、炭化水素類は疎水性が強いため、多量の界面活性剤やオレイン酸等の極性油を併用することにより、浴水に溶解したときの乳化分散性や浴用剤自体の安定性を高めている。 Combinations of various surfactants and oil components have been proposed as self-emulsifying bath agents that become cloudy when self-emulsified when introduced into bath water (Patent Documents 1 to 4). Typical oily components blended in these self-emulsifying bath agents are saturated hydrocarbons that are liquid at room temperature, typically liquid paraffin. Liquid hydrocarbon oils give a moist feeling to the skin, but since hydrocarbons are highly hydrophobic, they can be dissolved in bath water by using a large amount of surfactants and polar oils such as oleic acid. The emulsifying dispersibility and the stability of the bath agent itself are improved.
さらに乳化分散性と感触を高めるために、炭化水素油にエステル油を加え、さらに非イオン性界面活性剤量を一定量配合した自己乳化型浴用剤が報告されている（特許文献５）。
これら自己乳化型浴用剤は、浴湯に投入する前は透明な液体であり、浴湯に投入した際に自己乳化により浴湯が白濁するという特徴を有する。しかしながら、炭化水素油やエステル油等の油性成分や界面活性剤を調整し、浴湯へ投入した際の乳化性、肌へのしっとり感、及び保存安定性のすべてを満たす自己乳化型浴用剤を得るには十分でなく、更に検討が行われている。例えば、肌へのしっとり感を増すために炭化水素油を増やすと、保存時に浴用剤自体が白濁や分離し易くなり、特に白濁等が生じた浴用剤を浴湯に投入したときの分散性が悪くなり油浮き等が生じてしまう。
従って、本発明の目的は、長期保存安定性に優れ、浴湯への投入時の乳化分散性が良好で、かつ十分な乳濁（白濁）状を呈する自己乳化型浴用剤を提供することにある。
These self-emulsifying bath agents are characterized by being a transparent liquid before being added to the bath water and becoming cloudy due to self-emulsification when being added to the bath water. However, a self-emulsifying bath agent that adjusts oily components and surfactants such as hydrocarbon oils and ester oils and satisfies all of the emulsifiability, moist feeling on the skin, and storage stability when poured into bath water. It is not enough to get and further studies are underway. For example, if hydrocarbon oil is increased to increase the moist feeling on the skin, the bath preparation itself becomes easily clouded or separated during storage. It will worsen and oil floating will occur.
Accordingly, an object of the present invention is to provide a self-emulsifying bath agent that is excellent in long-term storage stability, has good emulsifying dispersibility when charged into bath water, and exhibits a sufficient emulsion (white turbidity). is there.
そこで本発明者は、長期保存安定性と自己乳化性について種々検討した結果、炭化水素油と一定のＨＬＢの非イオン性界面活性剤の２種以上に加えて、グリセリンと水を組み合せて配合することにより、高温で長期間保存後も透明性が確保されており、浴湯への投入時に乳化分散性が良好であることを見出し、本発明を完成した。 Accordingly, as a result of various studies on long-term storage stability and self-emulsifying properties, the present inventor has formulated a combination of glycerin and water in addition to two or more hydrocarbon oils and certain non-ionic surfactants of HLB. As a result, it was found that the transparency was ensured even after long-term storage at high temperature, and that the emulsification dispersibility was good when it was put into the bath water, and the present invention was completed.

本発明の浴用剤には、さらに通常の浴用剤に用いられる成分、例えば無機塩類、有機酸類、グリセリン以外のアルコール類、水溶性高分子類、生薬類やビタミン類等の各種薬効成分、雲母末や中性白土等の白濁剤、色素や顔料類、殺菌剤、防腐剤等を適宜配合できる。また、ラベンダー油やローズ油等の天然香料類、シトラール、ムスク、リモネン等の合成香料類等の香料を配合することができる。 The bath agent of the present invention further includes components used in ordinary bath agents, such as inorganic salts, organic acids, alcohols other than glycerin, water-soluble polymers, various medicinal components such as herbal medicines and vitamins, mica powder, Further, cloudiness agents such as neutral clay, pigments and pigments, bactericides, preservatives and the like can be appropriately blended. Moreover, fragrance | flavors, such as natural fragrance | flavors, such as lavender oil and rose oil, and synthetic fragrance | flavors, such as citral, musk, and limonene, can be mix | blended.
本発明の浴用剤は、自己乳化型であり、浴湯に投入したときに乳化して、白濁する。特に、４０℃の浴湯に溶解したとき、乳化粒子の平均粒子径が１μm以下となるのが好ましい。また本発明浴用剤は、液状であり、組成物自体の外観は、透明であるのが好ましい。 The bath agent of the present invention is a self-emulsifying type, and emulsifies and becomes cloudy when put into bath water. In particular, when dissolved in 40 ° C. bath water, the average particle size of the emulsified particles is preferably 1 μm or less. Further, the bath agent of the present invention is liquid, and the appearance of the composition itself is preferably transparent.
表１及び表２に示す組成の自己乳化型浴用剤を常法により製造し、原液安定性、乳化性及び白濁度を評価した。結果を表１及び表２に併せて示す。なお、配合直後の原液に、分離又は析出があったものは評価を行わなかった。 Self-emulsifying bath agents having the compositions shown in Table 1 and Table 2 were produced by a conventional method, and the stock solution stability, emulsifying property and white turbidity were evaluated. The results are shown in Table 1 and Table 2 together. It should be noted that the stock solution immediately after blending that had separation or precipitation was not evaluated.

〈評価基準〉
○：白い
△：若干白い
×：透明
(Evaluation methods)
(1) Stock solution stability:
Each sample was allowed to stand in a thermostatic bath at 50 ° C. or 25 ° C. for 1 month, and the state of the solution was observed with the naked eye and evaluated according to the following criteria.
<Evaluation criteria>
○: Transparent uniform Δ: Opaque uniform ×: Separation or precipitation (2) Emulsification:
30 g of each sample was put into a 40 ° C./180 L bath and dissolved uniformly, and the emulsifiability was observed with the naked eye and evaluated according to the following criteria.
<Evaluation criteria>
○: Uniform cloudy solution without oil float Δ: Slight oil float is observed but uniform cloudy solution ×: Oil float or cream-like separation is observed (3) White turbidity 30 g of each sample in 40 ° C / 180 L bath water The turbidity was evaluated by the following criteria.
<Evaluation criteria>
○: White △: Slightly white ×: Transparent
表１及び表２より、本発明の自己乳化型浴用剤組成物は、高温保存しても透明液状を保持しており、かつ自己乳化性も良好であった。グリセリンを含まない比較例１〜３、精製水を配合しない比較例４、グリセリン量の多い比較例５及び６いずれも特に浴用剤自体（原液）の高温保存安定性が悪かった。界面活性剤が１種類の比較例７〜９は、いずれも浴用剤自体（原液）の保存安定性および乳化性に劣るものであった。
また、本発明の組成物を用いて入浴したところ、肌感触が良好であり、かつ香り立ちも良好であった。
From Tables 1 and 2, the self-emulsifying bath agent composition of the present invention maintained a transparent liquid state even when stored at a high temperature and had good self-emulsifying properties. Comparative Examples 1 to 3 not containing glycerin, Comparative Example 4 not containing purified water, and Comparative Examples 5 and 6 having a large amount of glycerin were particularly poor in high-temperature storage stability of the bath preparation itself (stock solution). Each of Comparative Examples 7 to 9 having one surfactant was inferior in the storage stability and emulsifying property of the bath agent itself (stock solution).
Moreover, when it bathed using the composition of this invention, the skin feel was favorable and fragrance | flavor was also favorable.
