Global ingredient manufacturer Seppic is making plastic-free formulation easier and more accessible than ever with Sepimax Zen. The non-microplastic polymer can be used in everything from shampoo to sunscreens, offering all the properties of its plasticky peers, but without the damage. Microplastics are a grey area, so while the ECHA would not class Sepimax Zen as a microplastic, others would. Clearer definitions are sorely needed, but we consider this inherently biodegradable ingredient to be a good improvement on the non-biodegradable products it is replacing.
