[Means for solving the problem]
In view of such a situation, the present inventors have intensively studied for an emulsified composition having a low risk of generating an aldehyde due to a change over time, and as a result, polyoxybutylene polyglycerin monoalkyl (monoalkenyl) ) By combining an ether and a polyglycerin monofatty acid ester, the content of a surfactant having a polyoxyethylene group or a polyoxypropylene group can be reduced, and thus the polyoxyethylene group or the polyoxypropylene group can be reduced. They have found that it is even possible to produce an emulsified composition without containing a surfactant, and have completed the invention. That is, the present invention relates to the following technology.
(1) An emulsified composition comprising, as hydrophilic surfactants, polyoxybutylene polyglycerin monoalkyl (monoalkenyl) ether and polyglycerin monofatty acid ester.

(3) Emulsion composition of the present invention The emulsified composition of the present invention is characterized by containing the above essential components, polyoxybutylene polyglycerin monoalkyl (monoalkenyl) ether and polyglycerin monofatty acid ester. I do. For the purpose of developing the emulsified composition of the present invention, it is preferable to avoid containing a compound having a polyoxyethylene group or a polyoxypropylene group having an HLB of 12 or more, for example, to suppress the total amount of these compounds to 1% or less. It is particularly preferable that the content be substantially zero. Here, “substantially” means that it is not contained except for the so-called carryover derived from the raw material, in other words, it is not blended.
Further, from the standpoint is at the emulsion composition to enhance the emulsion stability of the present invention, oil components used, i.e., 2 0 ° C. conditions hydrocarbon and polar oil a configuration of components having the properties of the liquid at 1 atm It is preferable to adopt only the configuration. The polar oil referred to in the present invention is an oil component containing oxygen in a molecule and having a high polarity. In terms of specific physical properties, in the organic conceptual diagram, the organic / inorganic Means a value of 2 to 10. Preferred specific examples include triglyceride isooctanoate (glyceryl trioctanoate, organic 510 inorganic 180, organic / inorganic = 2.83), cetyl isooctanoate (cetyl octanoate organic 530 inorganic 60, organic / Inorganic = 8.83), diglycerin tetraolate (organic 1560 inorganic 268 organic / inorganic = 5.82) and the like. These may contain only one kind, or may contain two or more kinds in combination. The preferred content of such a polar oil is 5 to 20% by weight, more preferably 8 to 16% by weight, based on the total amount of the emulsion composition. In the present invention, an arbitrary component other than these components can be contained as long as the effects of the present invention are not impaired. Examples of such optional components include polyhydric alcohols such as glycerin, isoprene glycol, 1,2-pentanediol, propylene glycol, and 1,3-butylene glycol; saccharides such as sorbitol, maltitol, and sucrose; and alkyl derivatives thereof. , Liquid paraffin, squalane, isopropyl palmitate, oleyl oleate, olive oil, turtle oil, synthetic whale wax, castor oil, etc., silicone oils such as dimethyl polysiloxane, dimethyl diphenyl siloxane, fluorinated silicone, and fatty acid soap etc. Activators, anti-inflammatory agents, antibacterial agents, cell activators, melanin production inhibitors, fragrances, and the like. As the emulsified form of the emulsified composition of the present invention, any form of a normal emulsified form such as W / O, O / W, or a complex emulsion of W / O / W or O / W / O can be applied. A particularly preferred form is an O / W emulsified form. This is because particularly excellent stability can be obtained in such an emulsified form.
Such an emulsified composition can be produced by treating an essential component and an optional component according to a conventional method. The thus obtained emulsified composition of the present invention does not generate aldehydes over time, maintains excellent safety for a long period of time, does not cause any irritation to ordinary people, and reacts hypersensitively to a very small amount of irritants. It can be said that the formulation is suitable for cosmetics used by people with sensitive skin.
＜実施例３＞以下に示す処方に従って本発明の乳化組成物２を作成した。即ち、イ、ロを８０℃に加熱し、イに徐々にロを加えて乳化し、ホモジナイザーにかけて乳化粒子を均一化し、攪拌冷却して乳化組成物２を得た。このものを実施例１と同様の試験を行ったところ、アセチルアセトン法での発色はスコア１であったが、４０℃１ヶ月の保存条件下でごく微量の離しょうを見た。これより、本発明の乳化組成物では油剤を極性油のみで構成することが好ましいことがわかった。このものは実施例１の乳化組成物と同様に安全性が高く化粧料として使用できることが判った。尚、イソステアリン酸イソステアリルは有機概念図に於いて、有機性７００であり、無機性が６０である。

Example 3 An emulsified composition 2 of the present invention was prepared according to the following formulation. That is, (a) and (b) were heated to 80 ° C., and (b) was gradually added to (a) for emulsification, and the mixture was homogenized with a homogenizer to homogenize the emulsified particles. When this was subjected to the same test as in Example 1, the color development by the acetylacetone method was score 1, but a very small amount of delamination was observed under the storage condition of 40 ° C. for 1 month. From this, it was found that in the emulsified composition of the present invention, it is preferable that the oil agent be composed of only polar oil. It was found that this was highly safe, and could be used as a cosmetic, like the emulsified composition of Example 1. It should be noted that isostearyl isostearate has an organic nature of 700 and an inorganic nature of 60 in the organic conceptual diagram.
