Oilwith

Oilwith is a term used to describe a class of oil-in-water emulsions and additive blends designed to reduce friction and improve heat management in lubrication systems. The name signals a shift from fully oil-based lubricants toward emulsified formulations, and appears in industrial literature as both a formulation category and a processing approach.

Typical oilwith formulations combine a base oil phase with an aqueous phase, emulsifiers, and functional additives such as anti-wear agents and corrosion inhibitors. The aim is to control viscosity and lubricity while enhancing heat transfer.

Manufacture relies on high-shear mixing or phase inversion to create stable emulsions, with stabilization achieved by compatible surfactants and polymers. Droplet sizes range from nanometers to a few micrometers, and stability depends on temperature, pH, and salinity.

Applications span metalworking fluids, hydraulic systems, and cooling-lubrication in machining and manufacturing. Benefits may include reduced oil consumption, improved heat removal, and lower emissions, while risks include phase separation, material compatibility issues with seals, and regulatory considerations related to disposal and biodegradability. Real-world performance varies with formulation and operating conditions.

Environment and safety considerations emphasize biodegradability, aquatic toxicity, and worker exposure. Adoption depends on lifecycle cost, performance testing, and compliance with environmental and occupational regulations. Research continues to optimize stability and expand suitable materials and equipment.
