Abstract We present experimental data on water repetitively brought in contact with cellophane. Although this hydrophilic polymer is insoluble in water, repetitively immersing it in water changes the liquid’s properties. We compare the physicochemical properties of the water left over after removing the cellophane to those of previously published data on water repetitively brought in contact with other in water insoluble polymers (cotton wool or Nafion). Some of the properties are similar. All the properties considerably differ from those of the Milli-Q® water used. On lyophilizing these waters, solid residues remain. The residues are soluble in water. The chemical nature of the residues differs from that of the perturbing polymers. Keywords Water · Cellophane · Cellulose · Mirror symmetry · Interfacial water · Nafion
Introduction Customarily, it is assumed that natural or artificial cellulose polymers do not affect nearby bulk water. The insolubility of cellulose in water underlies this assumption [1]. Nevertheless, the recently well-checked experiments that we Electronic supplementary material The online version of this article (https://doi.org/10.1007/s10973-020-10185-0) contains supplementary material, which is available to authorized users. * Roberto Germano [email protected] 1

performed have upturned this assumption [2–4]. We perturbed Milli-Q water by bringing it repetitively in contact with hydrophilic cellulose (HC) (cotton wool), cellulose acetate or cellulose nitrate polymers. The physicochemical properties of the water left over removing the polymers differ from those of Milli-Q® water. For example, the perturbed water is an optical active, far-out-of equilibrium self-organizing system. It contains molecular associates with sizes reaching hundreds of nano-meters (nm).1 The values of the physicochemical variables of water perturbed with a cellulose polymer are correlated [2–4].
