Abstract: A lubricant for conveyor chains of bottled products, set for lubricating through direct application without dilution and in a discontinual way, in prolonged intervals, leaving a layer or film on the surface of the conveyor chain. The lubricant is composed of an homogeneous mixture of one or more fluids of silicon such as emulsified polydimethylsiloxane; one or more fatty acids such as the oleic acid; one or more amines such as the tensoactive product derived from an ethoxylated amine; one or more hydrocarbons such as the white mineral oils; one or more emulsifiers such as the sorbitan monooleate; and one or more polyglycols such as the polyalkylene-glycol, and alternatively a microbicide.
