Description
本発明は、皮膚洗浄剤組成物に関する。
The present invention relates to a skin cleanser composition.
従来から、脂肪酸塩を含有し、泡立ちが良く、乾燥後の肌にべたつき感やつっぱり感を生じさせず、洗い上がりをさっぱりとさせることができる皮膚洗浄剤組成物が提案されている(例えば、特許文献1参照)。しかし、前記皮膚洗浄剤組成物は、金属イオンを多く含む硬水で使用すると、洗浄中に前記硬水のカルシウムイオン等の2価金属イオンと、脂肪酸塩とが結合し、脂肪酸の金属塩が生じるため、泡立ちが遅くなる、乾燥後の肌につっぱり感が生じるなどの問題がある。
このため、硬水でも泡立ちと皮膚の感触に優れた洗浄剤として、脂肪酸塩、アミドエーテル誘導体、及び金属封鎖剤を含有する皮膚洗浄剤組成物が提案されている(例えば、特許文献2参照)。しかし、前記提案では、従来の金属封鎖剤が種類により配合量に制限があること、また、配合上限が定められていないものについても製剤の安定性や皮膚刺激性の点から配合量が制約されるため、金属封鎖剤の効果を十分に発揮できるものではなかった。 Conventionally, a skin cleanser composition that contains a fatty acid salt, has good foaming, does not give a feeling of stickiness or firmness to the skin after drying, and can refresh the skin after washing (for example, Patent Document 1). However, when the skin cleanser composition is used in hard water containing a large amount of metal ions, a divalent metal ion such as calcium ion of hard water and a fatty acid salt are combined with each other during washing to produce a fatty acid metal salt. There are problems such as slow foaming and a feeling of tension on the dry skin.
For this reason, a skin cleanser composition containing a fatty acid salt, an amide ether derivative, and a metal sequestering agent has been proposed as a cleanser excellent in foaming and skin feel even in hard water (see, for example, Patent Document 2). However, in the above proposal, the amount of the conventional sequestering agent is limited depending on the type, and the amount of the compound that does not have an upper mixing limit is restricted from the viewpoint of the stability of the preparation and skin irritation. Therefore, the effect of the metal sequestering agent cannot be fully exhibited.

Therefore, the effect of the metal sequestering agent cannot be fully exhibited.
また、乾燥後の肌のつっぱり感を解消するために、ポリエチレングリコールや特定の低刺激性界面活性剤を含有する洗浄剤組成物が提案されている(例えば、特許文献3、特許文献4参照)。しかし、これらの提案では、すすぎ時のぬるつきにより、きれいに洗い落とした感じがしないという問題がある。
したがって、硬水での泡立ちが早く、硬水での泡量が豊富で、硬水でのすすぎ時にぬるつきがなくきれいに洗い終えた実感が得られ、乾燥後の肌にべたつき感、及びつっぱり感がなく、外観安定性が良好な皮膚洗浄剤組成物の提供が強く望まれている。 Moreover, in order to eliminate the dryness of the skin after drying, a detergent composition containing polyethylene glycol and a specific hypoallergenic surfactant has been proposed (see, for example, Patent Document 3 and Patent Document 4). . However, these proposals have a problem that they do not feel washed away due to the luster when rinsing.
Therefore, foaming with hard water is quick, the amount of foam in hard water is abundant, there is no stickiness when rinsing with hard water, the feeling that it has been washed cleanly is obtained, the skin after drying is not sticky, and there is no feeling of tension, It is strongly desired to provide a skin cleanser composition having good appearance stability.
