PROBLEM TO BE SOLVED: To provide an aerosol product, mounted with an aerosol spray device to spray hair growth tonic with liquefied gas, which prevents liquefied gas being sprayed from vaporizing and spreading at once, and prevents the hair growth tonic from dripping and causing deterioration of blood circulation promotion effect on a scalp.SOLUTION: An inner periphery of a spray nozzle 3 of an aerosol spray device has a shape of an inverse taper surface 7, with an inner diameter thereof gradually increased from a back side of the spray nozzle to a nozzle tip 5 which serves as a vaporization control section. A vaporization control space k is a space surrounded by the inverse taper surface 7. Liquefied gas includes dimethyl ether accounting for more than 20% by weight with a score of 100% by weight representing an entire content. A hair growth tonic includes a carrot extract, vitamin E, cepharanthine in addition to lower alcohol accounting for 10% or more by weight with the score of 100% by weight representing the entire content. The dimethyl ether accounts for 30% or more by weight with the score of 100% by weight representing a total of the carrot extract, the vitamin E, the cepharanthine, the lower alcohol and the dimethyl ether.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 育毛剤を液化ガスで噴射するエアゾール噴射装置を備えたエアゾール製品において噴射中液化ガスが気化して一気に広がるのを防ぐと共に液ダレによる育毛剤の頭皮に対する血行促進の阻害を抑制する。【解決手段】 エアゾール噴射装置の噴射ノズル3は気化制御部として噴射口5よりも奥側から噴射口5へかけて漸次内径を大きくする逆テーパー面7を内側面に備え、気化制御空間kは逆テーパー面7に囲まれた空間であり、液化ガスはジメチルエーテルを含み、収容物全体を100重量%として収容物中前記ジメチルエーテルが20重量%より多く含まれ、育毛剤はニンジンエキスとビタミンE類とセファランチンとを含むと共に収容物全体を100重量%として前記低級アルコールを10重量%以上含むものであり、ニンジンエキスとビタミンE類とセファランチンと低級アルコールとジメチルエーテルとの合計100重量%中、ジメチルエーテルを30重量%以上とする。【選択図】 図1
