Description

この発明は、汗の臭いを防ぐ効果が高く、且つ長時間にわたり持続力のある制汗・防臭剤組成物に関する。   The present invention relates to an antiperspirant / deodorant composition that is highly effective in preventing sweat odor and has a long-lasting ability.

一般に、汗の臭いは、汗腺などの皮膚分泌腺を通して生じた皮膚分泌物が、皮膚常在菌により分解され、低級脂肪酸、ケトン、アンモニア、アルデヒドなどの成分に変化し発生する。これら臭いを抑えるためには、汗や皮膚分泌物を抑制する方法、皮膚常在菌を殺菌、滅菌あるいは制菌する方法、発生した臭い成分を吸着消臭する方法、または、香料などによりマスキングする方法などが一般的に知られており、従来より、制汗デオドラント剤には、これらの方法が併用される場合が多い。   In general, the smell of sweat is generated when skin secretions generated through skin secretory glands such as sweat glands are decomposed by skin resident bacteria and changed into components such as lower fatty acids, ketones, ammonia and aldehydes. In order to suppress these odors, a method of suppressing sweat and skin secretions, a method of sterilizing, sterilizing or sterilizing resident skin bacteria, a method of adsorbing and deodorizing generated odor components, or masking with a fragrance, etc. Methods are generally known, and conventionally, these methods are often used in combination with antiperspirant deodorant agents.

しかしながら、従来のデオドラント化粧料では、制汗剤、殺菌剤、消臭剤が配合されているものの、皮膚刺激性や薬事上の規制などの点から配合できる量には限界があり、安全性,有効性の両面を兼ね備えた制汗・防臭剤組成物は未だ得られていないのが現状である。   However, although conventional deodorant cosmetics contain antiperspirants, bactericides, and deodorants, there are limits to the amount that can be added in terms of skin irritation and regulatory regulations, The present condition is that the antiperspirant and deodorant composition which has both sides of effectiveness has not been obtained yet.

なお、グリセリルモノアルキルエーテルは、ノニオン性界面活性剤として知られており(非特許文献1参照)、その化粧料への配合,抗菌作用等についても研究されている(特許文献1〜特許文献5参照)。   Glyceryl monoalkyl ether is known as a nonionic surfactant (see Non-Patent Document 1), and its formulation into cosmetics, antibacterial action, and the like have also been studied (Patent Documents 1 to 5). reference).
