The effect of anionic surfactant – polyvinylpyrrolidone complexes formed in aqueous solutions
on physicochemical and functional properties of shampoos
Polimery 2018, No 7-8, 549

DOI: dx.doi.org/10.14314/polimery.2018.7.10

Summary

Based on the analysis of published results of studies on the complexes of polymers with surfactants in aqueous solutions, shampoo formulations containing sodium dodecyl sulfate (SDS) and polyvinylpyrrolidone (PVP), which are mild to the skin, were developed. The measurements of surface tension, foamability and zein number confirmed that the aqueous solutions of PVP and SDS may be used as bases for shampoo with low irritation potential. The most favorable evaluation of physicochemical and sensory tests was obtained for a shampoo containing PVP90 (termed the original shampoo). A comparison of selected functional properties of the original product with the commercial product was performed. Both shampoos were of comparable quality, but the zein number (ZN), which is a measure of irritation potential, was reduced by more than 30 % compared to the commercial shampoo.
