Particulate matter (PM), such as air pollutants and pollens, are known to cause skin ageing through skin inflammation. It is important to develop formulations which protect the skin from PM. We previously developed a conventional water‐in‐oil emulsion with a synthetic surfactant, distearyldimonium chloride, modified bentonite (C‐W/O), which protects skin from allergens. In the present study, we developed a novel water‐in‐oil emulsion with a natural surfactant, lecithin, modified bentonite (N‐W/O).

一种含有卵磷脂改性膨润土的新型油包水乳液可防止城市灰尘和雪松花粉对皮肤造成伤害。

众所周知，空气污染物和花粉等颗粒物 (PM) 会通过皮肤炎症导致皮肤老化。开发保护皮肤免受 PM 伤害的配方非常重要。我们之前开发了一种传统的油包水乳液，其中含有合成表面活性剂二硬脂基氯化二铵、改性膨润土 (C-W/O)，可保护皮肤免受过敏原的侵害。在本研究中，我们开发了一种新型油包水乳液，其中含有天然表面活性剂、卵磷脂、改性膨润土 (N-W/O)。
