Gibberellic acid

Gibberellic acid (CAS 77-06-5) is a naturally occurring plant growth regulator produced by the fungus Gibberella fujikuroi. It is commercially available under trade names including Ryzup, Ralex, Maxon, and UVEX, and is commonly abbreviated as GIB in technical and procurement contexts. No E-code designation applies to this substance.

In agriculture, gibberellic acid stimulates cell elongation and division by activating gibberellin-responsive genes, promoting stem extension, fruit set, and seed germination in crops such as grapes, citrus, and cereals. In personal care formulations, it functions as a skin conditioner by influencing cellular renewal processes at low concentrations.

Gibberellic acid is supplied as a white powder in technical and formulation-grade qualities, with purity levels typically ranging from 90% to 95%. It falls under HS code 29322980 and is subject to REACH registration requirements within the EU. Packaging formats commonly available include fiber drums and sealed polyethylene-lined bags.
