凡士林是一種烷系烴或飽和烴類半液態的混合物,也叫礦脂,由石油分餾后制得。其狀態在常溫時介于固體及液體之間,因不同用途而有棕、黃、白三種顏色。天然凡士林取自烷屬烴重油等石油殘油濃縮物;人造凡士林則取自用純地蠟或石蠟、石蠟脂使礦物油稠化的混合物。凡士林有礦物油氣味,而沒有煤油氣味。

凡士林的用途:

1、天氣干燥情況時,可涂于臉部、手部、腳部或身體皮膚,滋潤保濕。

2、涂在鼻腔內膜避免因太干燥而流血,或鼻出血的人可以涂在鼻孔內壁阻止繼續出血。

3、可用來當作護唇膏涂于唇上,其油脂成份可保持唇部水分。

4、感冒時涂在鼻子周圍的皮膚上,以免擤鼻涕過多摩擦變紅。

5、可避免因濕尿布長期接觸皮膚而引起濕疹。
