Polyisobutenyl succinimide (PIBSA) is an oil-soluble copolymer which is used as an additive in various chemical products. It is most commonly used as an emulsifier, thickener, stabilizer, and softening agent in personal and beauty care items. PIBSA is composed of polyisobutene (PIB) and succinimide (SI) monomers. It is typically found in shampoos, lotions, shaving creams, body washes, creams, makeup foundations, and other cosmetics. PIBSA provides high viscosities and unmatched emulsification capabilities in a wide range of product applications. It also works as an excellent suspending agent, dispersant, and quat binding agent. PIBSA is non-toxic, highly compatible with different types of surfactants, and resistant to microbial degradation.
Polyisobutylene Succinimide is an ashless dispersant prepared from highly reactive isobutylene . With good detergency and dispersancy, it can inhibit the formation of carbon deposit and film on the piston of engine. It doesn’t contain chlorine.

Particularly suitable for blending environment-friendly engine oils
Polyisobutylene succinimide is a type of dispersant additive that is commonly used in lubricants. It is made by reacting polyisobutylene with maleic anhydride, followed by a reaction with an amine compound to form the succinimide structure.
Polyisobutylene succinimide is used to improve the dispersibility of contaminants in lubricants, such as soot, sludge, and varnish. By dispersing these contaminants, the additive helps to prevent the formation of deposits and keep the lubricant clean.
In addition to its dispersing properties, polyisobutylene succinimide also acts as a detergent and anti-oxidant. It helps to clean and remove existing deposits and inhibits the formation of new deposits. This promotes better lubrication and reduces the potential for engine wear and friction.
Polyisobutylene succinimide is commonly used in engine oils, transmission fluids, hydraulic fluids, and industrial lubricants. It is particularly effective in high-temperature applications, where it can help to prevent the degradation of the lubricant and maintain its performance.
Overall, polyisobutylene succinimide is a versatile additive that provides dispersing, detergent, and anti-oxidant properties to lubricants. It helps to keep engines and equipment clean, reduce friction and wear, and improve the overall performance and lifespan of the lubricant.
