体香剂是一类作用在人体皮肤上的物质,来减低因排而产生的体味。出汗之所以有异味是因为汗液中包含了人体中分泌的氨基酸、脂质等物质,细菌在汗液的环境下极易繁殖,并分解汗液中的有机化合物,从而产生异味。

体香剂一般采用喷雾喷射或者走珠涂抹的方式进行使用。

止汗剂(或称抑汗剂)是体香剂的一种,其原理是减少出汗量。另外有些能抑制细菌生长或杀菌。许多体香剂有香水,用来掩盖异味。但如果只用香水,香水的分量必须十分多。

体香剂通常喷在腋下。在许多人身上,腋下是汗味最强烈的地方。腋下空气不流通,蒸发低;而湿度高,温度暖,通合细菌生长。而体毛增加了表面面积,令细菌有更多生长空间。

常见的成分有:

  • 酒精:杀菌。[1]
  • 铵明矾(硫酸铵铝):抑制细菌生长。[2]
  • 化物:多排汗会提高酸碱值pH),如氢氧化铝不溶于pH 5-9。它们阻碍大汗腺的排汗,防止脂质的排出。当洗澡时,肥皂水的pH更高,化合物会再溶化。[3]
  • 香水:提供香气以掩盖原有体味。
