What is Lubrizol polyisobytylene succinimide?

Lubrizol polyisobytylene succinimides are designed to meet the special protection needs of all engines. Their excellent physical and functional properties make them ideal for use in lubricants to increase the durability and performance of engines. Representative polyisobytylene succinimide analogs have been assessed under the EPA HPV program.

What are polyisobutylene succinimides (PIBSA)?

Polyisobutylene succinimides (PIBSA) are used to make dispersants that are used in tailor-made formulations to meet the challenging demands of engine oils.

Who is exposed to Lubrizol polyisobytylene succinimides?

Lubrizol polyisobytylene succinimides are sold to industrial customers who formulate engine oils. Workers in these industrial exposure scenarios, professional workers and consumers can be exposed to polyisobytylene succinimides via dermal contact. The potential for inhalation exposure is limited by their low volatility.

What is the mechanism of action of polyisobutenyl (PIB) succinimides?

Polyisobutenyl (PIB) succinimides are widely used as low/medium temperature detergent/dispersant additives in lubricants. To elucidate their mechanism of action, soluibility, micelle formation, adsorption, zeta potential, sedimentation and detergency studies have been carried out on a range of PIB succinimides in non-aqueous media.

How do polyisobytylene succinimides work?

Their dispersant action helps keep small particles suspended so that they can be removed by the oil filter and not build up in the engine. Polyisobytylene succinimides commonly are produced by reacting polyisobutylene succinic anhydrides with an amine.

Are polyisobytylene succinimides harmful?

The health effects of polyisobytylene succinimides have been assessed as part of the Petroleum Additives Succinimide Dispersants Category under the U.S. Environmental Protection Agency (EPA) voluntary High Production Volume (HPV) Challenge Program.
