Zinc Oxide (ZnO) is an inert, natural mineral that is commonly used in cosmetics as a thickening, lubricating, & sunscreen active ingredient. Zinc Oxide is a physical UV filter that provides the safest, most comprehensive broad-spectrum protection against the sun’s harmful UV rays.
Mineral-based sunscreen filters such as TiO2 and ZnO offer a natural solution to UV protection in personel care products compared to traditional organic filters which can be harmful to humans and environment. Among UV filters, zinc oxide (ZnO) is the only globally approved UV filter that can provide broad spectrum UV protection by blocking harmful UVA and UVB rays.
Having sensitive skin can be a real challenge for consumers when it comes to buying cosmetics. It does, however, present an opportunity for cosmetics companies. It is becoming increasingly common for people to consider themselves as having sensitive skin.
There are two main types of skin cancer, melanoma & non-melanoma skin cancer. Non-melanoma skin cancers are the most common type of skin cancer. However, as they are not required to be reported to cancer registries the actual incidence & mortality statistics available are best estimates & not always up to date.
In the ever-changing landscape of sun protection products, consumers are struggling to keep up & understand the cosmetic industry’s current sun protection message. The high mortality rate from UV ray associated melanomas, one person dies of melanoma every hour & 86% of melanomas are caused by UV rays from the sun, means that it is widely accepted by consumers that protection of the skin from the sun is a necessity.
The world’s coral reefs are under threat. It is estimated that by 2050, 90% of reefs will die due to rising temperatures, with climate change the biggest threat to coral reefs. Overfishing, pollution & nutrient enrichment from agricultural runoff & sewage are also considered significant threats to coral reef health.
Biocompatibility of designed MicNo-ZnO particles: Cytotoxicity, genotoxicity and phototoxicity in human skin keratinocyte cells.
Recently, designed platelet shaped micron particles that are composed of nano primary particles, called MicNo (=Micron+naNo) particles, have been developed to exploit the benefits of nano size, while removing the adverse effects of nanoparticles. It has been shown that MicNo-ZnO particles exhibit both micron and nanosized particle characteristics.
