Can you tell me a little bit about this beer by-product ingredient?
Harry McIlwraith: Barley TONIQ is our newest active. It's derived from the beer brewing process, and it targets irritated or sensitive skin.
When beer is made, barley is harvested, milled, malted and then mashed, which means they put it into a big mixing vessel called a mash tun. They wash it with hot water, which is used to extract all the sugars, which then goes into the fermentation vessel to produce alcohol and turn it into the beer that we know.
What's leftover from that process, though, is the barley grounds, the so-called spent grains. These spent grains have had their sugars extracted, but they still contain a lot of protein. Those spent grains go into another process where enzymes are added and it breaks down that protein into the peptides, polypeptides, amino acids that are relatively well known, and they are the materials that are doing the skin-soothing benefits.
The way that we have shown its efficacy is via this in-vivo study where we looked at the reduction of erythema of the skin. When skin has been irritated you can see a very obvious patch of redness on the skin erythema. We looked at the reduction in that redness over two hours and you can see in only 30 minutes when used to 1% you can see a visible reduction in redness, which builds up to a 23% reduction in redness after two hours when used at 3%.
It's a very fast-acting ingredient and something that we're very happy with.
Where did the concept for this ingredient come from?
Harry McIlwraith: We seem to have unintentionally given ourselves a portfolio of ingredients that have been derived from alcoholic beverages. It's not intentional that we've focused a lot of our portfolio that way. It just has been that especially the alcoholic drinks industry has a lot of waste. We initially started working with a brewery in the UK called Adnams Brewery and we work very closely with them to produce one of our previous materials called Gin TONIQ, which is derived from the gin distilling process.
