Hand Sanitizers Could Damage Critical Supporting Cells In The Brain

Chemicals found in common household disinfectants, glues, and furniture textiles could damage supporting cells in the brain during critical stages of their development, a new study based on human cell cultures and mice has found.
Starting with 1,823 compounds of unknown toxicity found in the environment, Erin Cohn, a molecular biologist at Case Western Reserve University in Ohio, and colleagues identified two classes of chemicals that either killed or halted the maturation of cells called oligodendrocytes under laboratory conditions.
Oligodendrocytes are a type of neurological support cell: They wrap around neurons to form an insulating covering that keeps brain signals scooting along at speed.
One of the two chemical classes identified were quaternary compounds. These are used in disinfectant sprays, wipes and hand sanitizers, and personal care products such as toothpaste and mouthwash to kill bacteria and viruses, and can be ingested or inhaled if used incorrectly or in poorly ventilated spaces.
