“…Pillowcases, as well as socks, undergarments, linens, diapers, and a range of other consumer products embedded with copper oxide particles, are industrially produced and have been commercially available for many years now [29]. These products have been tested in numerous safety trials and found to be non-sensitizing and non-irritating [30,31].…”

Abstract:Copper plays a key role in many of the physiological processes that occur in the skin. Previously it was found that sleeping on pillowcases impregnated with microscopic copper oxide particles results in reduction of wrinkles and fine lines. In the current study, it was examined if sleeping on copper oxide impregnated pillowcases results also in skin lifting and skin brightness. A four week, double blind, randomized study was performed, during which 45 women, aged 37-54, slept on copper oxide containing pillowcases (test group, n = 23) or on control pillowcases without copper oxide (control group, n = 22). Facial and eye skin surface was measured using an F-ray 3D measurement system and surface analysis was conducted using Image-pro ® plus. Skin brightness was measured using a tristimulus colorimeter. Sleeping on the test pillowcases resulted in statistically significant skin lifting on the cheek area (p = 0.039) and eye area (p = 0.001) after four weeks of use as compared to baseline. The mean skin brightness in those sleeping on the test pillowcases increased after two (p = 0.024) and four weeks (p = 0.008). No statistically significant changes occurred during the study in the study participants using the control pillowcases. Statistically significant differences between both groups were recorded at two and four weeks for skin brightness and skin lifting, respectively. In conclusion, sleeping on copper oxide containing pillowcases results in facial skin lifting and brightness of the skin.

“…We used copper oxide for two main reasons: (a) copper oxide is a very reactive copper compound with potent biocidal properties, which is being used successfully in many consumer, industrial and medical device products (Borkow andGabbay 2004, 2006;Borkow et al 2007Borkow et al , 2010aBorkow and Monk 2012;Borkow 2012), and (b) copper oxide is a non-soluble copper compound. Obviously in such products, it is important that the active ingredient in the product remains in the product for the life of the product; in this case that it would not be lost into the running water.…”

“…Egyptian green and did not show any and antifungal activity against all isolated fungi. Fungi were killed when exposed to higher concentrations of copper (Borkow and Gabbay, 2005;Borkow, 2012). This means that the responding of fungal strains was differed according to fungal strain and copper dose.…”

Seven fungal strains, namely: Aspergillus terreus, A. clavatus, A. niger, A. humicola, A. sydowii, Paecilomyces variotii and Fusarium oxyspourm were isolated from Stelae dates back to the 19 th Dynasty of the New Kingdom of the reign of King Sity in ancient Egypt, respectively. The isolated fungi were identified by studying their macro and micromorphology. Furthermore, nanogel, nanolime and nonosilver were tested to study their ability to inhibit the fungal growth of the isolated fungi. The potent fungus, a. terreus, which showed best result in nanosilver biosynthesis Aspergillus clavatus (25mm) > Aspergillus niger (24mm) > Aspergillus sydowii (22mm) > Paecilomyces variotii (20mm) and Fusarium oxysporm (20mm) > Aspergillus terreus (14mm) > Aspergillus humicola (12mm), was further identified by the molecular technique (18SrRNA). Nanosilver. On the other hand, nanolime followed nanosilver in its antifungal effect against isolated fungal strains and its activities followed the order: Aspergillus niger (22mm). Different nanomaterials (nanogel, nanolime and nanosilver) were prepared either chemically followed by nanogel exhibited the highest antifungal activities against the isolated fungi whereas nanolime exhibited weak antifungal activity. The effect of archaeological pigments (Malachite, Azurite, Egyptian green and blue) on the isolated fungi as antifungal agents was also investigated. It has been found that Azurite and malachite showed a considerable effect more than the Egyptian green and Egyptian blue. The hydrolysis of animal glue, binding material, was also studied by cultivating the isolated fungi in broth medium containing animal glue as nitrogen source and the proteolytic activity of their culture filtrate has been assayed.
