The evidence, graded
expert consensusUS safety reviewers (2015) assessed 16 galactomannans: gums from legume seeds such as guar, locust bean (carob) and tara, and ingredients made from them, used mostly to condition skin and hair and to thicken. Their large molecules are unlikely to pass through skin. Their list names tara, hydrolyzed tara, carob and guar gum, hydroxypropyl guar and guar hydroxypropyltrimonium chloride. They judged all 16 safe as used, and asked makers to limit pesticide residues and heavy metals.Johnson 2015 · International Journal of Toxicology ↗
