Zinc oxide (ZnO) is perhaps the most widely used chemical in industry today, with applications ranging from pharmaceuticals to ceramics, rubber, and semiconductors. Given its use in end-consumer goods and technology, ZnO quality standards must be directly aligned with industry-wide standards for safety, legislation, and performance. Choosing the appropriate ZnO supplier is thus a multi-step …

Analytical Strategies for Particle-Size Verification Using SEM, DLS, BET, and XRD Zinc oxide (ZnO) has been known for decades as a versatile compound for use in sunscreens and cosmetics as well as industrial catalysts and ceramics. More recently, the advent of nanotechnology research has increased the use of ‘nano-ZnO’ due to the drastically higher surface …

How to Tell if Zinc Oxide Is Nano or Non-Nano Read More »

Zinc oxide is a material that seems simple, but its performance depends on things that happen long before the bag or drum gets to your plant. The production method, thermal “French” (indirect), thermal “American” (direct), or wet-chemical (precipitation and related variants), determines the purity, particle size and shape, surface area, coatings, and consistency from batch …

One of the first health concerns for parents is keeping their baby’s sensitive skin safe from the sun, especially in warm places or when they are outside. Infants’ skin is thinner and more sensitive than adults’, which makes them more likely to get UV damage, irritation, and dehydration. As people have learned more about the …

For individuals with sensitive skin, buying sunscreens can prove to be a gamble. This is mainly because, upon application, many chemical sunscreens tend to irritate, burn, or cause redness on sensitive skin. Dermatologists have relied on mineral sunscreens, particularly zinc oxide, for sensitive skin individuals for the past decade, and the reasons for using them …

Introduction: Choosing the appropriate sunscreen can sometimes be as challenging as deciphering an unfamiliar language. You may have come across numerous recommendations for using sunscreens that contain titanium dioxide or zinc oxide, but what makes these components so essential for safeguarding against the sun’s harmful effects? Zinc oxide and titanium dioxide are two naturally occurring …

Introduction: A common product that helps shield the skin from the sun’s damaging rays is sunscreen. It functions by absorbing or reflecting ultraviolet (UV) radiation from the sun, which can harm the skin and raise the risk of developing skin cancer. Active ingredients found in most sunscreens include zinc oxide and titanium dioxide. which are …

Introduction: Two immiscible liquids are combined to form emulsions, which are stabilized by an emulsifying agent to stop separation. Surfactants, which lower the interfacial tension between the two phases and facilitate easier mixing, are commonly used as emulsifying agents. Oil-in-water (O/W) and water-in-oil (W/O) emulsions are the two basic varieties of emulsions (Graillat, Lepais-Masmejean, & …

Abstract: The effects of surface coatings on the acute and long-term toxicity of six zinc oxide nanoparticles (ZnO-NPs) against the marine copepod Tigriopus japonicus were investigated in this work. Yet, the copepod’s antioxidant gene expression revealed that these variations were caused by the hydrodynamic size and ion dissolution. In acute testing, bare and hydrophobic particles …
