Frequently asked questions

Is methoxydiglycol safe during pregnancy?

ECHA lists diethylene glycol monomethyl ether (methoxydiglycol, CAS 111-77-3) with a harmonised CLP classification for reproductive toxicity (H360 - may damage fertility or the unborn child), which places it in the highest hazard band for developmental/reproductive effects. Animal and mechanistic work show it is metabolised to methoxyacetic acid, a metabolite implicated in reproductive/developmental toxicity in multiple studies, supporting a demonstrated mechanism. Dermal/topical use gives measurable systemic absorption for small glycols used as solvents, so exposure from cosmetics is non‑negligible (moderate).

Is methoxydiglycol safe while breastfeeding?

Because the substance has a harmonised H360 reproductive classification and is metabolised to methoxyacetic acid (a known reproductive toxicant), there is concern for transfer to nursing infants; advisory bodies note uncertainty but flag lactation as a relevant route and the absence of data on milk levels. Dermal/topical use can produce systemic levels (measurable), so breastfeeding exposure cannot be ruled out.

Is methoxydiglycol safe for baby skin?

Hazard (H360) remains highest (h=3) due to harmonised CLP classification and animal evidence. Mechanistic concern (metabolism to methoxyacetic acid) is demonstrated. Exposure (e) is increased by +1 for infants (per your instruction): because the compound is a small, moderately skin‑permeable solvent with measurable dermal uptake in adults, infant skin (higher SA:weight and immature barrier) raises likely systemic exposure to high.
