Frequently asked questions

Is casein safe during pregnancy?

Casein (milk protein; CAS 9000-71-9) has no harmonised reproductive classifications in ECHA Annex VI, no SCCS/CIR statements identifying reproductive hazard, and no peer‑reviewed evidence of teratogenicity or reproductive toxicity in humans or animals. As a high‑molecular‑weight protein it is not expected to be systemically absorbed from topical use (PubChem/ECHA/CosIng listings and general protein toxicology).

Is casein safe while breastfeeding?

No evidence that topical casein causes reproductive or lactation hazards; no mechanistic data for endocrine activity. Maternal topical use is unlikely to give systemic exposure sufficient to affect breastfed infants given the protein's large size and lack of reported systemic toxicity in regulatory/peer-reviewed sources.

Is casein safe for baby skin?

Casein is a large milk protein unlikely to penetrate intact infant skin to a meaningful extent; no infant‑specific toxicology indicating harm to 0–3 year skin. Therefore exposure from cosmetic topical application is considered negligible. Note: if the product formulation contains proteolytic enhancers or penetration enhancers, absorption could differ (no such data found).

How does VeriMom score casein?
