Our take
Is Sorbeth-30 Tetraoleate a Good Ingredient?
It rates Good as a stable, effective nonionic PEG emulsifier that improves oil-water mixing and wash-off with typically low irritation. It's Good rather than Great because its benefits are functional and it can sting if it migrates into the eyes.
