Sources/Uses

Used as a preservative in foods, cosmetics, and medicines; [HSDB] The parabens (methyl, ethyl, propyl, and butyl) were the most widely used preservatives in cosmetics (0.1% to 0.8%) until their sensitizing potential was recognized; [Marks, p. 115]

Parabens are an uncommon cause of allergic contact dermatitis; [Marks, p. 115] Food use limited to 0.1%; [Hawley] Observations from animal studies include mild skin and eye irritation and a low order of toxicity in high-dose oral studies; Skin sensitization has been reported from cosmetics and topical medications; A moderate eye irritant (saturated aqueous solution); Practically non-toxic in animal studies: Oral LD50 (mouse) >8000 mg/kg (Effects included flaccid paralysis and ataxia); [HSDB] An eye and mild skin irritant; May cause skin sensitization; [eChemPortal: ERMA] "Parabens can induce allergic contact dermatitis, mainly in chronic dermatitis and wounded skin."
