Is glucomannan safe during pregnancy?

No harmonised CLP reproductive classifications or SCCS/CIR flags were found. The Cosmetic Ingredient Review (CIR) polysaccharide-gums safety assessment lists glucomannan among commonly used polysaccharide gums and notes low irritation/toxicity in topical uses; reproductive toxicity signals are not reported. Clinical/peer-reviewed literature shows only limited clinical use data (e.g., oral use for constipation in pregnancy) without evidence of teratogenicity, but that is systemic/oral context rather than topical cosmetic exposure. Sources: CIR safety assessment and pregnancy clinical report. (CIR; PubMed).

Frequently asked questions

Is glucomannan safe during pregnancy?
No harmonised CLP reproductive classifications or SCCS/CIR flags were found. The Cosmetic Ingredient Review (CIR) polysaccharide-gums safety assessment lists glucomannan among commonly used polysaccharide gums and notes low irritation/toxicity in topical uses; reproductive toxicity signals are not reported. Clinical/peer-reviewed literature shows only limited clinical use data (e.g., oral use for constipation in pregnancy) without evidence of teratogenicity, but that is systemic/oral context rather than topical cosmetic exposure. Sources: CIR safety assessment and pregnancy clinical report. (CIR; PubMed).
Is glucomannan safe while breastfeeding?
No evidence of reproductive/lactation toxicity from topical cosmetic use and no SCCS/CIR or harmonised CLP warnings. Peer-reviewed searches show little or no data on lactation-specific risks from topical glucomannan; oral systemic data are limited and do not indicate lactation-specific hazards. Topical cosmetic use therefore defaults to no identified hazard. (CIR; PubMed).
Is glucomannan safe for baby skin?
No hazard or mechanistic reproductive/baby-skin concerns identified in CIR or regulatory lists. Absorption from topical cosmetic use is expected to be negligible for a high‑molecular‑weight polysaccharide (CIR), but immature infant skin has higher permeability; per your scoring rules, exposure (e) is increased by +1 for babies compared with adults though still low. No infant-specific adverse data were located. (CIR; SpecialChem/CosIng summaries; EWG).
How does VeriMom score glucomannan?
VeriMom scores glucomannan at 100/100 (no known risks) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
