Cassia Angustifolia Seed Polysaccharide
A conditioning ingredient from senna seeds. Little research tests what it does on skin.
What it does
It’s a chain of the sugars galactose and mannose from the seeds of the senna plant, Cassia angustifolia. Guar gum is built from the same two sugars.
The evidence, graded
expert consensusUS safety reviewers (2015) assessed 106 polysaccharide gums and starches, which products use to thicken. They judged 105 safe as used, dextrin palmitate/ethylhexanoate, mannan, sodium carboxymethyl starch and Cassia angustifolia seed polysaccharide included; for hydrolyzed carrageenan they had too little data. They were concerned about chemicals used to modify some of them and asked makers to limit impurities.Johnson 2015 · Cosmetic Ingredient Review ↗
