The chart below (Fig. 4) shows the data obtained by comparing the previously described “basic” emulsion (5% of SESAMULS® OW and 14% of oily phase) and free of thickening agents, with the same emulsion to which some of the rheology modifiers most utilized in the cosmetics industry were added alternatingly.

The viscosity values obtained during the systematic study shows that adding rheology modifiers does not vary viscosity considerably; on the contrary, considerable decrease can be observed in the case of Hydroxypropyl Guar and Magnesium Aluminum Silicate. SESAMULS® OW‘s great versatility which enables the cosmetologist to achieve the desired viscosity by simply acting on the emulsifier concentration, with scarce utilization of rheology modifiers which often negatively affect the product ‘texture’ is confirmed in this case too.

The following chart (Fig. 5) shows the viscosity variation observed both in the “basic” emulsion (5% of emulsifier and 14% of oily phase) and the same emulsion upon adding some from among the consistency bodies most utilised in the cosmetics industry. It is clear that the presence thereof, even at low percentage, considerably increases the emulsion viscosity.

The chart below (Fig. 6) shows the comparison of “basic” emulsion viscosity values used as reference during this experiment, with the same emulsion to which waxes were added alternatingly. As observable, the effect on the emulsion viscosity is positive; viscosity increases considerably in all cases, except in the presence of
Cera Alba Wax.
