About
Cassava root fiber, a natural polysaccharide material used as an exfoliant and texturiser in gentle skincare formulations.
Manihot utilissima (cassava) root fiber consists primarily of resistant starches and cellulosic materials. The ingredient is not listed in EU cosmetic restriction annexes. Cassava root must be properly processed to eliminate cyanogenic glycosides (linamarin, lotaustralin); cosmetic-grade fiber should be cyanide-free. This is distinct from cassava flour, which requires specific processing. Cosmetic fiber forms are considered safe at recommended use levels.
Skin benefits
- Natural cellulose fiber provides gentle physical exfoliation
- Resistant starch acts as a skin-conditioning agent
Known concerns
- Must be verified cyanogenic-glycoside-free to avoid irritation or toxicity
