•A cleaner vision: Research supports safe, sustainable suds
89% Informative
Procter & Gamble sought to understand which surfactants in cleaners can cause eye irritation.
Researchers used the Summit supercomputer at the Department of Energy's Oak Ridge National Laboratory .
P&G has committed to global sustainability goals through its Ambition 2040 initiative.
The study grew out of the firm's commitments to product performance, safety and environmental sustainability.
Surfactants in shampoo and other cleaners that irritate the eye disrupt the outer corneal membrane to create microscopic holes that allow chemicals to penetrate to the tissues beneath.
Increased concentration of surfactants studied didn't necessarily increase damage to the membrane, at least in contact with the liposome alone.
The results could point to formulas for gentler, less-irritating surfactsants.
