When it comes to environmental responsibility and beauty brands, rethinking packaging tends to be at the top of the list.
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.
Part of the (cold) process
“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.
“This process not only saves heat energy, but also shortens the production time considerably.
“In this way, the manufacturing costs can also be reduced.”
An additional benefit, Düring notes, is that cold processing permits more gentle handling of the ingredient itself, as it is not heated.
