About
A filtrate from a cold-tolerant soil bacterium ferment. Postbiotic skin-conditioning ingredient with limited public data.
Pseudarthrobacter psychrotolerans is a psychrotolerant (cold-loving) Gram-positive bacterium isolated from polar/soil environments. The ferment filtrate is the liquid phase after culturing and filtering out the cells, containing secreted proteins, extracellular polysaccharides, and metabolites including cryoprotective compounds. Positioned as a postbiotic conditioning ingredient for skin-softening and resilience claims. Quality depends on fermentation, filtration, and preservation. No CIR/SCCS opinion. Cell-free format lowers infection risk but endotoxin/cell-wall-fragment control should be validated.
