ZinClear's significant potential advantage rests on the fact that it produces zinc oxide of pharmaceutical and food grade quality, with the added credibility of being manufactured in Australia. This unique combination lends itself to diverse applications across multiple sectors. Consequently, the augmentation of demand in just one of these sectors could enhance ZinClear's market positioning and revenue.

To elaborate on your query about the Risk/Benefit analysis of zinc, here are some excerpts from Wikipedia:

a) Zinc is an essential trace element for humans,^[4][5][6] animals,^[7] plants^[8] and for microorganisms^[9] and is necessary for prenatal and postnatal development.^[10] It is the second most abundant trace metal in humans after iron and it is the only metal which appears in all enzyme classes.^[8][6] Zinc is also an essential nutrient element for coral growth as it is an important cofactor for many enzymes.^[11]

Zinc deficiency affects about two billion people in the developing world and is associated with many diseases.^[12] In children, deficiency causes growth retardation, delayed sexual maturation, infection susceptibility, and diarrhea.^[10] Enzymes with a zinc atom in the reactive center are widespread in biochemistry, such as alcohol dehydrogenase in humans.^[13] Consumption of excess zinc may cause ataxia, lethargy, and copper deficiency.

In terms of Risk Mitigation:

b) As of 2021, only Zinc Oxide and Titanium Dioxide are recognised as safe and effective (GRASE) by the U.S. Food and Drug Administration (FDA),^[35] as currently there is insufficient safety data to support petrochemicals being safe, such as oxybenzone and avobenzone.

Research by the FDA on the safety of the main three organic UV filters (oxybenzone, homosalate and octocrylene) found that the three ingredients could be detected on the skin, in blood, in breast milk and in urine samples weeks after no longer being used.^[36][37]

And in terms of UV Protection Properties:

c) Zinc oxide can be used^[81] in ointments, creams, and lotions to protect against sunburn and other damage to the skin caused by ultraviolet light (see sunscreen). It is the broadest spectrum UVA and UVB absorber^[82][83] that is approved for use as a sunscreen by the U.S. Food and Drug Administration (FDA),^[84] and is completely photostable.^[85] When used as an ingredient in sunscreen, zinc oxide blocks both UVA (320–400 nm) and UVB (280–320 nm) rays of ultraviolet light. Zinc oxide and the other most common physical sunscreen, titanium dioxide, are considered to be nonirritating, nonallergenic, and non-comedogenic.^[86] Zinc from zinc oxide is, however, slightly absorbed into the skin.^[87]
