VeriMom¿Es beta-sitosterol seguro durante el embarazo?
CIR reviews of phytosterols note general cosmetic safety but some animal data show reproductive/embryotoxic effects at high or non-oral exposures; recent peer‑reviewed animal studies (mink, rodents, and a 2024 mouse study) report effects on reproductive endpoints, and beta‑sitosterol has demonstrated phytoestrogen/sex‑hormone‑modulating activity—so reproductive hazard is suspected (h=2) with a demonstrated mechanism (m=2). Topical cosmetic use gives low but measurable systemic exposure (e=1), much lower than doses in the animal studies; no harmonised CLP (ECHA Annex VI) classification was found. Sources: CIR phytosterol assessment; mink and rodent reproductive studies; recent 2024 mouse study; ECHA registration absence of harmonised classification.

- ¿Es beta-sitosterol seguro durante la lactancia?
- Same rationale as pregnancy: animal evidence of reproductive effects and demonstrated hormone/immune modulation suggest suspected hazard (h=2) with a demonstrated mechanism (m=2). Systemic transfer to milk after topical cosmetic use is expected to be low but measurable (e=1)—clinical human lactation transfer data are lacking.
- ¿Es beta-sitosterol seguro para la piel del bebé?
- No infant‑specific data showing reproductive or developmental toxicity from topical exposure; per instructions we do not increase hazard/mechanistic scores without infant‑specific evidence (h=0,m=0). Beta‑sitosterol is lipophilic with measurable but limited dermal absorption in adults (adult e≈1), and immature infant skin increases exposure — therefore exposure for baby skin is raised by +1 to e=2 (low→moderate). CIR and CosIng list beta‑sitosterol for topical use with no specific concentration restrictions in cosmetics.
