On the other hand, zinc oxide nanoparticles (ZnO-NPs) have excellent antibacterial, antifungal, and anti-inflammatory properties and a low cytotoxic effect [16], [17], [18], [19], [20].
* Exposure to Zinc Oxide can cause “metal fume fever.” This is a flu-like illness with symptoms of metallic taste in the mouth, headache, fever and chills, aches, chest tightness and cough. The symptoms may be delayed for several hours after exposure and usually last for a day or two.
Zinc oxide is a largely inert, white compound which is used very widely as a bulking agent or filler, and as a white pigment. It is found in some rubber, glass and ceramic products, and finds use in the chemical industry as a catalyst. It is also used in paints as a corrosion inhibitor and for mildew control.
Researchers also indicated that ZnONPs could affect the function of neural cells [21] and biocompatibility [22]. Zinc oxide nanoparticles (ZnONPs) have been found to impact brain monoamine levels (dopamine, norepinephrine, and serotonin) and various ions (Ca2+, Na+, K+, and Zn2+).
It is shown that GO-ZnO nanoparticles effectively inhibit the growth of gram-negative (E. coli, S. typhimurium) and gram-positive (Bacillus subtilis, Enterococcus faecalis) bacteria [68].

What are the disadvantages of ZnO?
Zinc oxide might be absorbed by the skin by a tiny amount. And the particles might be a pollution source to the ocean as well. Conclusion: Zinc oxide is a very commonly used chemical compound in various fields including a pharmacist, rubber production, food, ceramics, and outer materials like paint, pigments, etc.
The work function of these samples was determined from the measured values of Vc assuming the work function of a gold electrode to be 4.85 eV. The work function ΦZno of undyed zinc oxide is estimated to be 4.74 eV.
Generally, exposure to ZnO has been linked to adverse health and environmental effects (89–92) reported oxidative DNA damage in workers exposed to metal oxide Nms. ROS may cause ZnO NPs-induced cytotoxicity and genotoxicity. ZnO NPs are more toxic than other metallic oxide NPs because of their ion-shedding ability.
Is Zinc Oxide Safe For Your Skin? Usually, zinc oxide is a safe ingredient used in cosmetics. It is used in several over-the-counter skin protectants and sunscreen drug products. However, it is best to conduct a patch test on your skin before using any of such skin care products.
ZnO is currently listed as generally recognized as safe by the US Food and Drug Administration and used as a food additive, given that zinc is an essential trace element.
The antiseptic and astringent properties of Zinc Oxide work together to help reduce the risk of bacterial infections by reducing the skin's permeability and thereby obstructing the path of bacteria before they can adhere to or become internalized by the body.
Zinc oxide is an amphoteric oxide. It is nearly insoluble in water, but it will dissolve in most acids, such as hydrochloric acid: ZnO + 2 HCl → ZnCl2 + H2O.
The National Institutes of Health considers 40 mg of zinc a day to be the upper limit dose for adults and 4 mg of zinc a day for infants under age 6 months. Don't use intranasal zinc. This form of zinc has been linked with the loss of the sense of smell.
In June 2017, the European Commission decided to ban the use of veterinary drugs containing high doses of zinc oxide (3000mg/kg) from 2022. The use of zinc oxide in pig production must then be limited to a maximum level of 150ppm.
If you inhale a significant quantity of zinc oxide, more than you would encounter in daily life, you can become ill. This is extremely rare and typically occurs in industrial settings rather than in our home lives. Additionally, allergic responses to zinc oxide have been reported but these cases are also very rare.
Is zinc oxide safe to use everyday? Absolutely! Zinc oxide is one of those skincare champions you'll want to keep at the forefront of your daily routine. It's recognized for being incredibly safe, making it a go-to ingredient for daily use.
What side effects may I notice from receiving this medication? Side effects that you should report to your doctor or health care professional as soon as possible: allergic reactions like skin rash, itching or hives, swelling of the face, lips, or tongue.
Zinc oxide dust or fume can irritate the respiratory tract. Prolonged skin contact can produce a severe dermatitis called oxide pox. Exposure to high levels of dust or fume can cause metallic taste, marked thirst, coughing, fatigue, weakness, muscular pain, and nausea followed by fever and chills.
The renal toxicities of ZnO NPs are mainly characterized by tubular epithelial cell degeneration and apoptosis. The major toxicity mechanisms involve ROS generation, oxidative stress and activation of the mitochondrial apoptotic pathway in tubular epithelial cells.
Sunscreen products composed of it are particularly handy because ZnO sits on top of the skin. There it does its job of reflecting, scattering and blocking harmful ultraviolet rays. The following consumer products listed include zinc oxide in their composition: Cosmetics Sunscreen & sunblock.
ZnO-NPs exhibit attractive antibacterial properties due to increased specific surface area as the reduced particle size leading to enhanced particle surface reactivity. ZnO is a bio-safe material that possesses photo-oxidizing and photocatalysis impacts on chemical and biological species.
ZnO is a white powder that is insoluble in water. It is extensively employed as an ingredient in a variety of components and products, including batteries, ferrites, first-aid tapes, ceramics, glass, cement, lubricants, paints, ointments, adhesives, sealants, pigments, rubbers, plastics, ceramics, plastics [22,24].
By virtue of excellent oxidation capacity, tunable size, high chemical stability, low toxicity and simple preparation, n-type semiconductor zinc oxide (ZnO) has shown great potential as an efficient photocatalyst, especially in the degradation of organic pollutants, bacterial killing and electronic component ...
