Based on Mutagenicity test, Acute Oral Toxicity Test and four months Subacute Toxicity Test, It has been proved that Gardenia Blue is nontoxic if used conventionally. This product easily dissolves in water and hydrophilic solvent. It has maximal absorbance at the wave length of 598nm. Its dyeing ability is stable in water solvent of pH 2.5-8.0. Gardenia blue is more resistant to water than to light. Except when Fe2+ and Sn3+ exist, it is stable with metal ions existence.        It can ideally dye proteins and hydrocarbons.
