Specificatio Methylparabeni
Methylparabenum, numero CAS in registro 99-76-3 inscriptum, etiam Methyl p-hydroxybenzoate; 4-(Methoxycarbonyl)phenolo appellatur. Ad categorias productorum Revelatorum; Materiarum Functionalium; Aromaticarum pertinet. Numerus EINECS eius est 202-785-7. Formula molecularis huius chemici est C8H8O3Pondus moleculare est 152.15. Accedit quod nomen eius systematicum est acidum benzoicum, 4-hydroxy-,methyl ester. Methylparaben facile absorbetur ex tractu gastrointestinali vel per cutem. Hydrolyzatur ad acidum p-hydroxybenzoicum et celeriter excernitur sine accumulatione in corpore. In populatione cum cute normali, methylparaben fere non irritat et non sensibilizat; tamen, reactiones allergicae ad parabena ingesta relatae sunt. In multis praecipuis productis cutis/faciei inveniri potest.

Usus Methylparabeni: Methylparabenum notum est incrementum *Drosophilae* in stadiis larvalis et pupae tardare. Est medicamentum antifungale quod late adhibetur ut conservans in cibo, medicamentis et cosmeticis. *Mycocten*, et vulgo ut agens antifungale in mediis cibariis *Drosophilae* adhibetur. Methylparabenum est medicamentum antifungale saepe in gelis capillorum adhibitum. Compositum saepe invenitur in carpulis anaesthetici localis, fungens ut agens bacteriostaticus et conservans. Methylparabenum (etiam *Nipigin M*, *Tegosept*, et *Mycocten* appellatum) vulgo ut fungicida in mediis cibariis *Drosophilae* adhibetur. Usus methylparabeni notum est incrementum *Drosophilae* in stadiis larvalis et pupae tardare.
Methylparabenum nocet inhalatione, contactu cum cute et deglutitione. Oculos, systema respiratorium et cutem irritat. Cum eo uteris, vestes protectorias idoneas gere, contactum cum cute et oculis vita. Si contactus cum oculis acciderit, statim aqua copiosa ablue et medicum consule.
