  The present invention provides an acid addition salt of 5-aminolevulinic acid (5-ALA) or of a 5-ALA derivative (e.g. a 5-ALA ester) with an acid which has a pKa of about 5 or less, preferably about 3 or less, with the proviso that the acid is other than hydrochloric acid. Particularly preferred salts are those derived from acids selected from the group comprising sulphonic acid and its derivatives, hydrobromic acid, sulfuric acid, nitric acid and phosphoric acid. The salts in accordance with the invention are particularly suitable for use as photosensitizing agents in diagnosis and photochemotherapy of disorders or abnormalities of external or internal surfaces of the body.
