| titleOfInvention | Ultra-violet radiation absorbing compositions and compounds therefor |
| abstract | The novel compound 1,3-bis-(5-sulphobenzimidazolyl-2) benzene and/or a salt thereof, is prepared by sulphonating 1,3-bis-(benzimidazolyl-2) benzene, e.g. with chlorosulphonic acid in H2SO4 and, if desired, is converted to salts such as the sodium, potassium, ammonia and mono-, di- and tri-ethanolamine salts. 1,3-Bis-(benzimidazolyl-2) benzene is prepared by reacting o-phenylene diamine with isophthalic acid or a reactive derivative thereof, e.g. the acid chloride, amide or isophthalic aldehyde, in the presence of a condensation agent such as polyphosphoric acid. The material can also be obtained by the reduction of isophthalic acid di-o-nitranilide.ALSO:A composition, capable of absorbing U.V. radiation, comprises as the active ingredient 1, 3-bio-(5-sulpho-benzimidazolyl-2) benzene and/or a salt thereof, and an inert physiologically acceptable carrier suitable for topical application. The compound itself or the sodium, potassium, ammonium, or mono-, di- or tri-ethanolamine salts are particularly preferred. These compounds may be incorporated into solutions, jellies, creams or sprays for application and may be in the presence of conventional additives such as perfumes, skin-conditioning agents and insect repellents as well as other U.V. absorbing compounds such as the sodium salts of 2-phenylbenzimidazole-5-sulphonic acid and 3, 4-dimethylphenylglyoxylic acid or 4-phenylbenzophenone and 4-phenylbenzophenone-2\sv-carboxylic acid isooctyl ester. The novel compounds, of the sulphonic acid class, shield the skin from harmful U.V. radiation of short wavelengths. |
