Abstract
A composition including a buffered lactic acid having a pH within the range of from 3.0 to 6.5 is disclosed. The composition is a lubricant composition and has a water activity of from 0.03 to 0.60. The friction between the absorbent product and the skin/mucous membrane of the user is reduced when in contact with the skin or mucous membrane of the user. An additional advantage is that the composition has a pH in the acidic range which is close to the pH of the skin and/or mucous membrane.
