![]() ![]() Characterized by a high viscosity index, our White Mineral Oils keep stable viscosity at extreme temperatures.Almost all suspension oils will contain viscosity modifiers. Most oils on the market are either full mineral oil or a blend of mineral and synthetic oils. The viscosity index (V.I.) of an oil is a number that indicates the effect of temperature changes on the viscosity of the oil. It is well-known from Hydrodynamic Lubrication Theory that viscosity plays a central role in the lubrication regime encountered in the machine element the higher is the viscosity, the thicker is the oil film that separates the surfaces from touching each other. The Viscosity Index is very important in a suspension oil. Having excellent lubricating property, it can be used as a general-purpose lubricant. Viscosity is a measure of a lubricating oil’s resistant to flow.They do not support pathogenic bacterial growth and due to this property, they become ideal blending bases for Pharmaceutical / cosmetic applications.These products are treated for harmful polycyclic aromatic impurities and they pass the Polycyclic Aromatic Hydrocarbon test along with other purity norms in the Pharmacopoeia and comply with all the Regulatory requirements as per the European commission and USFDA. Lubricating oil viscosity index improver composition Abstract The invention is an improvement in wide viscosity range multigrade lubricants of the type having a mineral oil base into. The most important lubricants spec is the Viscosity Index (VI), a measure of viscosity variation at different temperatures.Our Unimin range of cosmetic / pharmaceutical grade Mineral Oils are highly refined, and tailor made for skincare and hair-care formulations.The lower the VI, the greater the change of viscosity. ![]() Our Mineral Oils are Paraffinic in nature and we offer a wide range for viscosities for varied applications. Viscosity Index (VI) is an arbitrary measure for the change of viscosity with variations in temperature. Mineral Oils are colourless, odourless mixtures of saturated liquid hydrocarbons obtained from the distillation of petroleum. ![]()
