CITRICIDAL™ is a broad spectrum antimicrobial compound synthesized from the seeds and pulp of grapefruit.

CITRICIDAL™ is an extremely potent and effective broad spectrum bactericide, fungicide, antiviral and antiparasitic compound. CITRICIDAL™ is environmentally safe with a low toxicity to man and animals.

Studies indicate that the antimicrobial activity of CITRICIDAL™ is in the cyto-plasmic membrane where the uptake of amino acids is prevented and disorganization of the cytoplasmic membrane and leakage of low molecular weight cellular contents.

CITRICIDAL™ is biodegradable according to the "Standard Test Methods for Determining the Anaerobic Biodegradation Potential of Organic Chemicals", ASTM Standards, Section 11, Water and Environmental Technology, Procedure E 1196-2, pp. 879-901,1993.
