Crystalline solid. Decomposes at 120°C. Contact may cause slight irritation to skin, eyes, and mucous membranes. May be slightly toxic by ingestion. Used to make other chemicals. Magnesium Hexafluorosilicate is used for mothproofing of textile fabrics. It has being used in the treatment of experimental caries of rats.

Delmopinol, a surface-active cationic agent. It was approved by FDA under the name Decapinol for the treatment of gingivitis and prevention of periodontitis. The drug interacts with the early acquired pellicle, the thin layer of saliva polymers and proteins covering teeth and gums, and forms a barrier over teeth and gums. This barrier prevents the microbial adhesion and colonisation on the tooth and gum surface. Delmopinol itself has no bactericidal activity.

Oxantel is a narrow-spectrum anthelmintic effective against whipworms in dogs and cats. It is ineffective against other roundworms, flukes, tapeworms or external parasites. Oxantel acts on the nervous system of the worms as inhibitors of acetylcholinesterase. Oxantel, a cholinergic anthelmintic and fumarate reductase inhibitor, significantly inhibited biofilm formation by P. gingivalis and disrupted established biofilms at concentrations below its MIC against planktonic cells. Oxantel was more effective against P. gingivalis in biofilm than metronidazole, a commonly used antibiotic for periodontitis. When oxantel was administrated to human beings for the treatment of trichuriasis, no drug reaction or side effects were reported, and the results of hematologic, biochemical and urinary examinations didn’t reveal any significant drug-related changes.
