About
A lipid mixture extracted from animal brain tissue. Carries prion (TSE/BSE) risk, faces EU restrictions on bovine CNS material, and has no independent safety review.
Brain lipids (INCI: Brain Lipids) is a complex mixture of phospholipids, cholesterol, sphingomyelin, and cerebrosides historically extracted from animal brain tissue (often bovine or porcine). The composition is biologically interesting because it overlaps with native skin barrier lipids. However, mammalian central-nervous-system tissue is the highest-risk source for transmissible spongiform encephalopathies (TSE/BSE prions); EU regulators specifically restrict bovine and ovine CNS-derived materials in cosmetics under specified-risk-material rules and CosIng listings. There is no SCCS or CIR opinion supporting cosmetic use, sourcing transparency is poor, and ethical concerns are significant.
