The evidence, graded
expert consensusUS safety reviewers (2023) assessed seven phenyl silicones, phenyl trimethicone and diphenylsiloxy phenyl trimethicone among them, used mostly to condition skin and hair and stop foaming. Apart from brief irritation in one test of a serum with a related silicone, possibly from the formula, they found no sign these irritate skin or cause allergy. They judged them safe as used, except in products that may be breathed in, such as sprays, where data were too thin.Raj 2023 · Cosmetic Ingredient Review ↗
