L'invention concerne le domaine des lubrifiants et fournit une composition lubrifiante monophasique comprenant une huile de base, une huile choisie parmi les glycols polyalkylés (PAG ou polyalkylene glycols) et un matériau à changement de phase, notamment de l'eau. La composition lubrifiante monophasique selon l'invention peut notamment être utilisée pour la lubrification d'un moteur pour véhicule. Elle possède des performances thermiques améliorées par rapport aux compositions lubrifiantes de l'état de la technique. Elle permet également de réduire l'encrassement des pièces du moteur. The invention relates to the field of lubricants and provides a monophasic lubricating composition comprising a base oil, an oil selected from polyalkyl glycols (PAG or polyalkylene glycols) and a phase change material, especially water. The monophasic lubricating composition according to the invention can in particular be used for the lubrication of a motor for a vehicle. It has improved thermal performance compared to the lubricant compositions of the state of the art. It also reduces clogging of engine parts.

Lubricant composition for refrigerating machine and compressor using the same

Disclosed is a lubricant composition for refrigerating machines, which is obtained by blending an acid trapping agent into a base oil. Also disclosed is a compressor using such a lubricant composition for refrigerating machines. The acid trapping agent is composed of a polyalkylene glycol derivative represented by the following formula (1): R1-[(OR2)e-OR3]f (1) , and the base oil is composed of at least one substance selected from polyvinyl ethers, polyalkylene glycols and ether compounds represented by the following formula (2). Ra-[(ORb)n-(X)-(ORc)k]x-Rd (2) (In the formulae, the symbols areas defined in the description.)

Surface conditioner for formed metal surfaces

Contact of acid or alkaline cleaned aluminum surfaces, particularly cans, with a water based composition containing a combination of (i) ethoxylated phosphate esters, ions of aluminum, zirconium, iron, tin, and/or cerium, and (iii) a metal etching component gives the surface after drying lowered surface friction without loss of high quality printability and lacquer adhesion and removes any brown spotting on the cans that may have developed during the cleaning or post-cleaning rinses.

Refrigerator oil composition and fluid composition for refrigerator
