A lubricant additive concentrate containing (i) dispersant that is the polybutenyl succinimide reaction product of a polyamine and polybutenyl succinic anhydride (PIBSA) derived from polybutene having a number average molecular weight (M) of from about 1300 to about 2500 daltons and a terminal vinylidene content of at least about 50% and maleic anhydride via an ene maleation process; (ii) overbased magnesium colloidal detergent having a total base number (TBN) of from about 300 to about 900 mg KOH/g; and (iii) organic friction modifier selected from hydroxyalkyl alkyl amines of Cto Chydrocarbons, at least one hydroxyalkyl alkyl ether amines of Cto Chydrocarbons, at least one alkyl ester amine derived from triethanol amine having a Cto Chydrocarbyl substituent, at least one non-basic, fatty acid amide, or a mixture thereof; wherein the combined mass % of dispersant (i) and overbased magnesium colloidal detergent (ii) in said concentrate is from about 15 to about 50 mass %: the mass ratio of (i):(ii) is from about 1:1 to about 6:1; and the concentrate contains from about 2 to about 10 mass % of organic friction modifier (iii); the remainder of the concentrate being composed of base oil and additives other than dispersant (i), overbased magnesium colloidal detergent (ii) and organic friction modifier (iii).

Additive concentrates for the formulation of lubricating oil compositions

A lubricating oil composition, a method of reducing low-speed pre-ignition (LSPI) in a direct-injected spark-ignited internal combustion engine, and a use of a lubricant composition to reduce LSPI events in such an engine. Preferably, the composition comprises a detergent package comprising a borated calcium detergent, wherein the detergent package provides a calcium content in the composition of at least 0.12 mass %, based on the total mass of the composition, and wherein the borated calcium detergent provides a boron content in the composition of at least 100 ppmm, based on the total mass of the composition. Optionally, the composition comprises a first detergent comprising a calcium detergent, and a second detergent comprising a borated calcium detergent.

Lubricating oil compositions

A method for attenuating effects of free radicals on a keratinous material of a subject in need thereof, comprising applying a composition to the keratinous material is provided. The composition comprises a physiologically or pharmaceutically acceptable medium and a short chain polypeptide having four amino acid units of a specific formula. The composition may be a sunscreen, a skin cream, a shampoo or a hair conditioner.

Short peptides and a method of use as an antioxidant

A short chain polypeptide having antioxidant activity is provided. The short chain polypeptide has 2 to 4 amino acids bonded to form a polypeptide chain having an amine-terminal end and a carboxyl terminal end; wherein a net charge of the short chain polypeptide is positive, the amino terminal amino acid is an amino acid selected from the group consisting of arginine, lysine and histidine, the polypeptide chain following from the amino terminus comprises a hydrophobic or neutral amino acid, and the polypeptide chain is free of an amino acid having a negatively charged side-chain group. A method to prepare a composition having antioxidant activity and a composition having antioxidant activity are also provided.

Novel dendrimeric peptide compounds are disclosed that have a formula represented by the following formula I: The compounds demonstrate antimicrobial activity and may be prepared as pharmaceutical compositions and used for the prevention and treatment of a variety of conditions in mammals including humans where microbial invasion is involved. The present peptides are particularly valuable as their effect is rapid, broad in spectrum and mostly indifferent to resistance provoked by standard antibiotics.
