Know your ingredient: Non-nano zinc

Did you know that zinc oxide is in a lot of sunscreens? Most people think of the white stuff that cricket players have on their noses and lips when they think about zinc, but zinc oxide is an ‘invisible’ ingredient in a lot of formulations. It’s what gives some sunscreens that opaque sheen. There has been some debate about whether the zinc oxide in sunscreens can be absorbed into the bloodstream which is why we use non-nano zinc in our products. Read on for a brief explanation of the difference between nano and non-nano zinc.

Origin

Zinc oxide is a white powder that is manufactured in a lab. The difference between nano and non-nano zinc is the size of the particles in the powder. The benefit of using a non-nano zinc oxide in skin products is that the particles are too large to absorb through the dermis and into the bloodstream.

History of use

People have been using sunscreens for centuries. Ancient Greeks used olive oil, ancient Egyptians used extracts of rice, jasmine, and lupine plants and the nomadic sea-going Sama-Bajau people of South East Asia used a paste called borak that was made from water weeds, rice and spices.

Zinc oxide paste has also been popular for skin protection for thousands of years. Synthetic sunscreens arrived on the market in 1928, with the first major commercial sunscreen launched in 1936 by the founder of L’Oreal, French chemist Eugène Schueller.

Applications

Zinc oxide particles in a cream base block or scatter UV rays so that they can’t get through to the skin.

It is highly debatable whether nano zinc oxide can get into the bloodstream through the pores but I prefer using non-nano zinc oxide – defined in Australia as having more than 90% of particles above 100nm in size – because non nano zinc works exactly the same way so why take the risk?

Water – the most overlooked ingredient in skincare

Stainless-steel-water-tank

This picture of a water tank may not look terribly exciting on the face of it, but let me tell you why you should be beaming as big as I am right now.

Liquid skincare solutions or creamy skin based solutions contain quite a lot of water or water-based infusions, our Saarinen Organics creams are ALL herbal infusion based. Unless your manufacturer is completely transparent, you wouldn’t know the origin of the water nor what type. It could be tap water for all you know and contain chlorine or fluoride or any measure of preservatives to prevent spoilage. Perhaps the skincare manufacturer is not even aware of what your water contains, as it’s not their priority or their ‘key ingredient’. Perhaps they’ve overlooked the fact that their “floral water” may not come from the most pure of sources or have been contaminated with chemicals or preservatives in the process from the company they buy it from if they do not make it themselves, as is often the case. Perhaps the containers it’s delivered in aren’t BPA free, and this chemical could be leeching into your products and into your skin, comprimising the integrity of the products you buy and use.

This is our stainless steel, food grade water tank. It captures fresh rainwater on the farm, the farm situated 200 metres from a beautiful National Park. It’s the water we drink from, the water we use to bathe and use to make our herbal infusions for our creams.

So you know exactly where our water came from. And you know exactly how our herbal infusions were made. And you know that the water used for our products is no lesser quality than the water the manufacturers themselves would personally drink.

It’s a highly overlooked ingredient in the manufacture of skincare products, as it’s the most basic and not the ‘active’ ingredient most companies wish to promote. But it’s in everything, and it’s hugely important. At least, when it comes to products of integrity.

I urge you to think about the products you use and consider that if you wouldn’t eat it, then don’t put it on your skin!

And admire our beautiful stainless steel, food-grade rainwater tank in all it’s glory!

It’s the little details that matter the most.
