The evidence, graded
expert consensusUS safety reviewers (2022) assessed 51 triglycerides. Their index lists C10–18 triglycerides, triethylhexanoin, triolein, caprylic/capric/myristic/stearic triglyceride and trihydroxystearin under that report. Its conclusion list names C18–36 acid triglyceride and triarachidin. Most soften skin, seal in moisture or thicken formulas, and the reviewers judged all 51 safe as used.Fiume 2022 · International Journal of Toxicology ↗
