4-Aminobenzoic acid Usage And Synthesis
Chemical PropertiesWhite to off white crystalline powder
UsesWidely distributed in nature as a B complex factor. Baker’s yeast contains 5 to 6 ppm, brewer’s yeast from 10 to 100 ppm. Occurs free and in ester form.
Usesgastric acid secretion inhibitor
Usesoctyl dimethyl PABA (padimate-O; p-aminobenzoic acid) is an FDA-approved sunscreen chemical whose InCI name is now ethylhexyl dimethyl PABA.
UsesPABA is a sunscreen chemical with an approved usage level of 5 to 15 percent. It is found to be irritating to sensitive skin, has the potential to cause sensitization, and is considered too water soluble. once extremely popular, this ingredient has practically disappeared from sunscreen formulations. PABA is a yellowish or colorless acid found in vitamin B complex.
DefinitionChEBI: An aminobenzoic acid in which the amino group is para to the carboxy group.
Brand nameRVPaba Lipstick (ICN).
General DescriptionColorless crystals that discolor on exposure to light and air.
Reactivity Profile4-Aminobenzoic acid is incompatible with ferric salts and oxidizing agents.
HazardQuestionable carcinogen.
Safety ProfileModerately toxic by ingestion and intravenous routes. Ingesting large doses can cause nausea, vomiting, skin rash, methemoglobinemia, and possibly toxic hepatitis. Experimental reproductive effects. Mutation data reported. Questionable carcinogen. Combustible. When heated to decomposition it emits toxic fumes of NO,. A topical sunscreen.
Purification MethodsPurify p-aminobenzoic acid by dissolving it in 4-5% aqueous HCl at 50-60o, decolorising with charcoal and carefully precipitating it with 30% Na2CO3 to pH 3.5-4 in the presence of ascorbic acid. It can be recrystallised from water, EtOH or EtOH/water mixtures. [Beilstein 14 IV 1126.]
