80REDUCTION OF SURFACE TENSION BY SURFACE ACTIVE AGENTSPresent study describes the decreases of surface tension with the addition of surfactants. Here we use Vivel Shampoo, Dove Shampoo and Clinic Plus Shampoo. All three shampoos show different surface active agent depending on their cleansing action. Different shampoo solutions are used to determine the surface tension. From the result it has been found that Clinic Plus shampoo reduces surface tension much better than other two. Lowering of surface tension helps these preparations to spread evenly over the surface that they come in contacthazra.ashoke@gmail.comReview512015Cleansing action,Surface tension,Surface active agents,ShampooAshoke HazraAsst.
