Cold processing, while not a new technique, is soaring in popularity as budgets tighten and brands seek to be more sustainable, but what cosmetic ingredients can be used in this eco-friendly way?
Cold processing not only saves heat energy, but shortens production time considerably
On the formulation side, thought tends to be given to ingredient genesis: is something organic, is it sustainably and ethically sourced, upcycled or biotech-derived? And at end-of-life: is it biodegradable?
But what about during manufacture? Increasingly, new ingredient press releases received by Cosmetics Business not only list an impressive roster of green certifications from the likes of COSMOS and Natrue, many also boast of being cold processable.
“Cold processing is a very energy-saving manufacturing process in which neither the water nor the oil phase needs to be heated,” explains Antje Düring, Formulation and Study Data Manager at cosmetic ingredients supplier Mibelle Biochemistry.
