为研究甘油、凡士林和普通护手霜3类产品的保湿性能，在微观摩擦试验机上对男女手背自然皮肤及使用过3类护手霜后的摩擦因数进行了试验。结果表明：女性手背皮肤的摩擦因数高于男性，分别为0．50和0．35；3类护手霜中甘油的润肤效果最为显著，女性和男性使用后的摩擦因数分别为1．45和1．31，而凡士林和普通护手霜的润肤效果相差不大；3类护手霜的润肤保持时间不等，凡士林护手霜的保持效果最佳，女性为337min，男性为350min，甘油护手霜和普通护手霜的保持效果相近，为217min～233min。

英文摘要：

In order to study moisturizing effect of glycerin, petrolatum and common hand - skin care cream, the friction coefficient of the natural skin on the back nf hand （without tile use of hand - skin care products） as well as that after using of hand - skin care products was measured by using of a micro - tribometer. The test results showed that the friction coefficient of the females was higher than that of the males on their natural hand- skin, which was 0.50 and 0.35 respectively. Among three kinds of hand - skin care products, the moisturizing effect nf glycerin is the most distinct one, and the other two were almost of the same level. The time duration for maintaining the moisturizing effect of petrolatum is the longest, that achieves 350 min for males and 337 min for females, while that glycerin and common hand cream are more or less the same and in the range of 217 min - 233 min.
