The evidence, graded
expert consensusUS safety reviewers (2021) assessed 40 saccharide (sugar) esters, which products use to soften and condition skin or keep oil and water mixed. Their conclusion names sucrose stearate, cocoate, laurate, palmitate, distearate and tetrastearate triacetate; the last is used at up to 15%, in mascara. They found the risk of skin irritation low, and tests showed no allergy. They judged all 40 safe as used.Scott 2021 · International Journal of Toxicology ↗
