Unilevers LA-headquartered prestige cosmetics brand Hourglass, acquired in 2017, had now transformed its entire colour cosmetics and skin care portfolio to vegan, following the final push on reformulating its red lipstick. The most complex change in the portfolio, Unilever and Hourglass had spent three years working to refine a blend made from existing ingredients that could replace industrys timeless vibrant red that had traditionally been made from carmine crushed female cochineal insects. For every pound of carmine, 70,000 insects were used; translating to around 1,000 per single lipstick.

Jason Harcup, global vice president of R&D for the prestige division at Unilever, said plenty of attempts had been made on non-animal carmine alternatives but all had fallen short on vibrancy.

This [ingredient] has been around for a very long time; its been around for centuries as a dye. So, for a very long time, people have tried to produce it and create it and they havent been able to, Harcup told CosmeticsDesign-Europe.

The fact is, [replacing carmine] is something that has been so coveted for so long, and seemingly unconquerable, but you can if you use good old science and technology. I think thats a learning and inspiration for us and other people as well, he said.

So, how exactly had the teams created a blend that matched carmine?

Unilever had opted to refine a combination of existing ingredients, rather than synthetically replicate carmine with a new ingredient or molecule, which Harcup said would typically result in the wastage of around 99% of materials used to make the lab-alternative.

You dont have to invent a new-to-the-world molecule, he said. So, the whole basis here was using new technology to find novel combinations of things that are good for everybody and the planet. And you get a much better solution. Its a glorified upcycling.

There was a hell of a lot of computational work, he said. Various technologies had been used to better analyse and digitally define carmine red, firstly, he said including reflectance spectroscopy that gave a digitised version of human vision for every colour of the visible spectrum. Once the true colour signature of carmine red had been defined, he said the teams then went ahead on trying to match it by more than 95%.

The resulting blend, finalised with around 175 non-digital experiments after the raft of computerised work, was a potent combination of ingredients that offered more than 97% of a performance match to carmine, Harcup said. And, importantly, this had been achieved thanks to extensive collaboration with more than 30 suppliers across the computational, experimentation, screening, development and ingredient fields.

Asked if Unilever planned to share this innovative blend with wider industry, given how complex it had been to create, Harcup said: Red O is a patent-pending ingredient which we plan to open-source in the coming year.

Because it had been so technically complicated to replace carmine with a vegan alternative far more complex than replacing other beauty and personal care ingredients he said the teams had carefully discussed the importance of making the ingredient more widely available.

We said: hang on a second, this is something that we want everybody to use. So, it is being made available.

And Harcup said given that 18-20% of all colour cosmetics contained carmine red and more than 10,000 product launches containing the ingredient happened in the last five years alone, there was certainly an important scale in terms of the potential a vegan alternative could offer the market. And, he said carmine was not just used in coloured cosmetics appearing in a plethora of other personal care products too.

Carisa Janes, founder of Hourglass and the driving force behind the vegan replacement project, said:Carmine is everywhere, from food and alcohol to paint, medication and lipstick. Creating a vegan alternative felt like an impossible feat at times, but it was such an important step we need to move away from treating living beings as expendable. Were excited to introduce the new ingredient in such an iconic shade of lipstick, a symbol of our commitment to animal welfare.

Harcup said Unilever was also excited about incorporating the ingredient into wider parts of its portfolio over time, particularly given vegan beauty and personal care opportunity. We definitely have that lets spread the love here and get this out as far as we can mentality. And one of the positives about the job I have, is I dont have any barriers doing that.
