體香劑








體香劑是一類作用在人體皮肤上的物質，來減低因排汗而產生的體味。出汗之所以有異味是因為汗液中包含了人體中分泌的水、氨基酸、脂質等物質，細菌在汗液的環境下極易繁殖，并分解汗液中的有機化合物，從而產生異味。


体香剂一般采用喷雾喷射或者走珠涂抹的方式进行使用。


止汗劑（或稱抑汗劑）是體香劑的一種，其原理是減少出汗量。另外有些能抑制細菌生長或殺菌。許多體香劑有香水，用來掩蓋異味。但如果只用香水，香水的份量必須十分多。


體香劑通常噴在腋下。在許多人身上，腋下是汗味最強烈的地方。腋下空氣不流通，蒸發低；而濕度高，溫度暖，通合細菌生長。而體毛增加了表面面積，令細菌有更多生長空間。


常見的成分有：




  • 酒精：殺菌。[1]

  • 銨明礬（硫酸銨鋁）：抑制細菌生長。[2]


  • 鋁或鋯化物：多排汗會提高pH，如氫氧化鋁不溶於pH 5-9。它們阻礙大汗腺的排汗，防止脂质的排出。當洗澡時，肥皂水的pH更高，化合物會再溶化。[3]

  • 香水：提供香氣以掩蓋原有體味。

Volkswagen Group MQB platform

Image
The Volkswagen Group MQB platform is the company's strategy for shared modular design construction of its transverse, front-engine, front-wheel-drive layout (optional front-engine, four-wheel-drive layout) automobiles. Volkswagen spent roughly $60bn [1] developing this new platform and the cars employing it. The platform underpins a wide range of cars from the supermini class to the mid size SUV class. MQB allows Volkswagen to assemble any of its cars based on this platform across all of its MQB ready factories. This allows the Volkswagen group flexibility to shift production as needed between its different factories. Beginning in 2012, Volkswagen Group marketed the strategy under the code name MQB , which stands for Modularer Querbaukasten , translating from German to "Modular Transversal Toolkit" or "Modular Transverse Matrix". [2] [3] MQB is one strategy within VW's overall MB (Modularer Baukasten or modular matrix) program which also includes th...
