A composition for an aqueous tacky lubricant, specifically targeted towards increasing lubricant retention to the moving components of chainsaws. More specifically, the composition includes a novel additive composition for environmentally-neutral lubricants. The ideal function of the composition would be to increase the adhesive qualities of an aqueous lubricant without compromising the coolant and lubricant roles of such a substance. To accomplish this, the composition includes an additive compound, that is made of a linear anionic polyamide and a cationic surfactant. The reaction between the linear anionic polyamide and the cationic surfactant creates a viscoelastic tackifier that helps the lubricant to cling to a moving chain thus preventing the lubricant from flinging off the chain when in motion. In other words, the additive compound is a tackifier agent, presented as novel both as an independent composition and in addition to extant lubricants. 1.
