SAS x LAS Technical DifferencesSkin MildnessZein TestThere is a very good correlation between acute skin irritation and the solubilization capacity of surfactants. A common model substance for the solubilization of proteins is zein, the protein from corn grain. In the Zein Test some of the water insoluble zein is dissolved, to a greater or lesser extend, by aqueous surfactant solutions. After centrifugation the dissolved zein is decomposed with concentrated sulfuric acid and the nitrogen content of the solution coming out of the protein is determined. Surfactants with high zeinvalues increase the roughness of the skin and are regarded as more skin irritant.

SAS presents lower SAS presents lower ZeinZein SolubilisedSolubilised value than value than LAS, indication of better skin compatibilityLAS, indication of better skin compatibility

The soiled mini-plates (1.0 g/1h aging) are washed with continuous foam generation.

The end point is set when the foam breaks permanently and the result is given by the number

of cleaned mini-plates

Mini-Plate Test

Objective: To evaluate the performance of

a dishwashing detergent, through a dynamic foam generation.

The Test: Continuous foam generation. Soiled mini-plates are washed

by hand.
