Copper naphthenate

Copper naphthenate is an organocopper compound with the properties of a fungicide, preservative, oil-borne protectant, and toxicant. Copper naphthenate increases serum and urine copper levels in exposed populations, causes skin irritation, and induces intraperitoneal toxicity in rats. Copper naphthenate inhibits the growth of decay fungi and molds on moso bamboo, kills the free-living stages of Ichthyophthirius multifiliis, and controls wood-boring insects and termites.

Biological Activity

Description

In Vitro

Copper naphthenate (1-10 mg/L; 4 h) at 4, 6, 8, or 10 mg/L incubated for 4 h at 23.5 °C kills 100% of Ichthyophthirius multifiliis protomonts, while 1 mg/L has minimal effect and 2 mg/L kills 58.3% of protomonts^[2].
Copper naphthenate (0.3-0.8% (calculated as Cu²⁺ content); 30 min immersion; 30 days fungal incubation) applied via heat-cold impregnation at 0.8% (calculated as Cu²⁺ content) achieves high mould resisting efficacy (85.9%, 94.8%, 70.3%) in Phyllostachys iridescens round bamboo against Aspergillus niger, Penicillium citrinum, and Trichoderma viride, respectively^[3].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
