Demulsifier additives prevent the formation of a stable oil-water mixture or an emulsion by changing the interfacial tension of the oil so that water will coalesce and separate more readily from the oil. This is an important characteristic for lubricants exposed to steam or water so that free water can settle out and be easily drained off at a reservoir.
All About Additives The Role of Antioxidants . Antioxidants are additives designed to prolong the life of a lubricant by increasing the oxidative resistance of the base oil. Antioxidants allow lubricants to operate at higher temperatures than would otherwise be possible without them. Many synthetic lubricants, especially hydrocarbon-based lubricating oils, are susceptible to degradation by
Antioxidants protect lubricants from thermal degradation by scavenging free radicals, thereby preventing the oxidation of the lubricant. TRiiSO's portfolio of antioxidants include both phenolic and aminic varieties. Some of these antioxidants are suitable for lubricants with incidental food contact and have been registered with NSF with a an HX-1 approval.

Oil additives are chemical compounds that improve the lubricant performance of base oil (or oil "base stock"). The manufacturer of many different oils can utilize the same base stock for each formulation and can choose different additives for each specific application. Additives comprise up to 5% by weight of some oils. Nearly all commercial motor oils contain additives, whether the oils are

In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of a hydroxyl group (—O H) bonded directly to an aromatic hydrocarbon group. The simplest of the class is phenol, C 6 H 5 OH.Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule.
A large number of additives are used to impart performance characteristics to the lubricants. Modern automotive lubricants contain as many as ten additives, comprising up to 20% of the lubricant, the main families of additives are: Pour point depressants are compounds that prevent crystallization of waxes. Long chain alkylbenzenes adhere to small crystallites of wax, preventing crystal growth.
Our broad range of antioxidants, light stabilizers, polymerization inhibitors, polymer modifiers, antiozonants & curing agents are employed to either aid processing, to chemically modify the polymer or to combat degradation, thereby extending a product’s life, appearance & performance by maintaining its strength, stiffness or flexibility.

Nonylphenol is used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers. It can also be used to produce tris(4-nonyl-phenyl) phosphite (TNPP), which is an antioxidant used to protect polymers,such as rubber,Vinyl polymers,polyolefins,and polystyrenics in addition to being a stabilizer in plastic food packaging.
Motor oil, engine oil, or engine lubricant is any of various substances comprising base oils enhanced with various additives, particularly antiwear additive in addition to detergents, dispersants and, for multi-grade oils, viscosity index improvers. Motor oil is used for lubrication of internal combustion engines. The main function of motor oil is to reduce friction and wear on moving parts
Gasoline additives increase gasoline's octane rating or act as corrosion inhibitors or lubricants, thus allowing the use of higher compression ratios for greater efficiency and power. Types of additives include metal deactivators, corrosion inhibitors, oxygenates and antioxidants.. Some additives are harmful and are regulated or banned in some countries.
To avoid such problems, additive suppliers and fuel producers use a series of tests to demonstrate that additives do not cause unexpected vehicle problems when making decisions about lubricity additive chemistry and treat rates . These tests include injector pump rig tests and lubricating oil compatibility tests to demonstrate no-harm performance on the vehicle. Compatibility with
Additives in lubricating oils Dr. Dmitri Kopeliovich Additives are substances formulated for improvement of the anti-friction, chemical and physical properties of base oils ( mineral,synthetic,vegetable or animal ), which results in enhancing the lubricant
The best carrier oil is cold-pressed and made from plants. Cold-pressed oils hold onto more of their beneficial properties since they are not subjected to heat. It’s also best to choose unrefined oils that have no additives. Butter and other animal fats are not good choices for carrier oil because the fatty acid profile doesn’t allow the

Phenol, any of a family of organic compounds characterized by a hydroxyl group attached to a carbon atom that is part of an aromatic ring. Besides serving as the generic name for the entire family, the term phenol is also the specific name for its simplest member,
Other release to the environment of this substance is likely to occur from: indoor use (e.g. machine wash liquids/detergents, automotive care products, paints and coating or adhesives, fragrances and air fresheners), outdoor use, indoor use in close systems with minimal release (e.g. cooling liquids in refrigerators, oil-based electric heaters) and outdoor use in close systems with minimal
Lubricating oil is refined from crude oil. After undergoing a purifying process colled sedimentation, the crude oil is heated in huge fractionating towers. The various vapors—which can be used to make fuel, waxes, or propane, among other substances—boil off and are collected at different points in the tower. The lube oil that is collected is filtered, and then additives are mixed in.
Oils are thin liquids made of long polymer chains, with additives for various extra properties. Common additives include antioxidants to keep the oil from oxidizing, corrosion inhibitors to prevent parts from corroding, and detergents to keep deposits from forming. These long chains are hard to squeeze out from between surfaces, making oils useful as a slippery barrier between them. Oils come
