Effect of plasticizer and surfactant on the properties
The results indicated that four-component blends had high surface hydrophilicity and surface roughness due to the presence of the surfactant. Glycerol incorporation into PVA/CTS blends resulted in higher flexibility and greater water absorption capacity of the three- and four-component polymeric blends compared with these blends with sorbitol.
Effect of plasticizer and surfactant on the properties
The plasticizer (glycerol or sorbitol) was added to the films to improve mechanical properties, also the surfactant (cocamidopropyl betaine) was the blend component to give the films washing properties because of potential usage of such materials as disposable wipes.

Combined effect of plasticizers and surfactants on the
It was observed a synergistic behavior between the plasticizer and the surfactants. Films with glycerol and high level of any of the surfactants behaved as films with larger amount of plasticizer (with lower tensile strength, higher elongation, and higher WVP).
- Do PVA films interact with plasticizers and surfactants?
- Commercial formulations of PVA films interact with plasticizers and surfactants when used in several products; therefore, the distribution of these components is highly relevant to the bulk and surface properties of these materials.
- Can glycerol plasticizer be added to PVA + surfactant mixed films?
- The addition of glycerol plasticizer to the PVA + surfactant mixed films has some dramatic and unexpected effects: The surface activity of d25 -C 12 E 5 systematically decreases with increasing glycerol content, whereas the opposite effect was observed when glycerol was included in the PVA + CTAB films.
- Do plasticizers and surfactants have a synergistic effect?
- Results were different when we studied the effect of both additives at the same time, that is, plasticizers and surfactants ( Fig. 5 ). As we observed for mechanical properties, an apparent synergistic effect between both components is shown, appreciable for low and high level of surfactants.
- How do plasticizers affect film coating?
- Film coating is a complex process that involves different factors. To ensure spreading and/or film forming capability plasticizers are added. The type and concentration of plasticizers can affect the film properties, as revealed by several investigations ( Mortada, 1990, Siepmann et al., 2005, James, 1997 ).
- Do Surfactants affect mechanical properties?
- In the absence of glycerol, surfactants had a significant effect on mechanical properties, but they did not modify significantly WVP of the films. It was observed a synergistic behavior between the plasticizer and the surfactants.
- Which surfactant reduces wettability of film solutions?
- The wettability of the film solutions was quantified by measuring their surface tension. The incorporation of plasticizers resulted in more flexible and manageable films and higher WVP. At low concentration, Tween 20 was the surfactant that reduced surface tension the most, while at high concentration it was lecithin.
