‘Babies Only’ Clear Zinc Sunscreen

I came across a brand called Babies Only who sell organic baby care products, but they also have products for mums as well. Some of them sound pretty nice!
I came across “this”:http://www.urbanbaby.com.au/ecomm5000.sf/?ObjectPath=/Shops/UrbanBaby/Products/BOCZSC sunscreen and thought it sounded pretty interesting, has anyone heard of it before? In the description it says:
“The Babies Only Clear Zinc Sunscreen is SPF 30+, 4 hours water resistant and non greasy. UVA & UVB Broad Spectrum. Suitable for all skin types, low irritant and fragrance free. TGA approved.”
