A composition comprising water, a glycol, and a polyalkylene glycol which has a biodegradability of at least 60% as determined using OECD 301F wherein the composition has a kinematic viscosity of at least 25 mm.sup.2/sec at 40° C. is useful as a rheology modifier, particularly in subsea applications. In some instances, the composition comprises 10 to 65 weight % water, 20 to 60 weight % of a glycol selected from ethylene glycol, diethylene glycol, triethylene glycol and tetra ethylene glycol, 10 to 40 weight % of a polyalkylene glycol, and 0 to 10% of additives based on total weight of the composition wherein the polyalkylene glycol has a—molecular weight of no more than 4000 g/mol and is characterized in that it is an oxyethylene/oxypropylene block copolymer having a weight percent of oxyethylene of at least 20% based on total weight of the copolymer.

One or more techniques and/or systems are disclosed for a dry-type lubricant for use in a dry product hopper to help improve dry product flow and to improve anti jamming properties of the dry product. The example lubricant can comprise a hydrophilic fiber, such as cellulose, having a width to length aspect ratio that provides a thin fiber. A plurality of hydrophobic particles are deposited on the surface of the fiber, resulting in a fiber surface exhibiting amphiphobic properties. Further, the fiber can operably absorb water, and then releases the absorbed water to the surface of the fiber under mechanical stress, such as when mixed with a product in a hopper. This can result in the water being disposed on the surface of the fiber, to provide lubrication to a product in a hopper to improve flow and anti jamming characteristics of the product in the hopper.

The present invention relates to drilling fluid comprising one or more linear internal olefin having from 15 to 18 carbon atoms and containing less than 25% branching based on the total amount of the linear internal olefin and a hydrogenated Fischer-Tropsch derived product.

The invention is the use, as oil for aluminium and aluminium alloys cold rolling, of a fluid having a boiling point in the range of from 200° C. to 400° C. and a boiling range below 80° C., said fluid comprising more than 95% by weight isoparaffins and less than 3% by weight of naphthens, a biocarbon content of at least 95% by weight, containing less than 100 ppm by weight aromatics.

The present disclosure relates to methods and compositions for making bio-based, biodegradable, and non-bioaccumulating lubricating base oils generated by esterifying alkoxylated polyols (average alkoxylation ≥3) with long-chain (≥C14) saturated and unsaturated fatty acids (FA) or fatty acids modified using industry recognized techniques.

The incorporation of highly refined, low viscosity index base oils along with a polymeric thickener produces a final readily biodegradable fluid with a significantly high viscosity. The present invention allows the formulation of a high viscosity readily biodegradable fluid where the vast majority of the fluid is mineral oil. Previous uses of mineral oils only allowed for formulation of substantially lower viscosity readily biodegradable fluids.

Described herein are methods of stabilizing the beta hydrogen of glycerol based esters by the insertion of alkoxy groups to significantly improve the thermal, oxidative, and hydrolytic stability of the ester and allow for controlling the molar density of esters bonds in the lubricants to maximize hydrolytic stability while maintaining biodegradability and further improving performance properties.

A composition comprising water and a polyalkylene glycol having an allyl content of less than 20 ueq/g, which composition has reduced foaming properties and preferably a biodegradability of at least 60% as determined using OECD 301F. The polyalkylene glycol can be made by forming a first intermediate comprising an oxypropylene block by reacting propylene oxide with a polyol initiator in the presence of a Double Metal Cyanide catalyst, and then reacting the first intermediate with ethylene oxide in the presence of a KOH catalyst.

The present disclosure relates to methods and compositions for making bio-based, biodegradable, and non-bioaccumulating lubricating base oils generated by esterifying alkoxylated polyols (average alkoxylation ≥3) with long-chain (≥C14) saturated and unsaturated fatty acids (FA) or fatty acids modified using industry recognized techniques.

Provided is a rolling bearing using a retainer, particularly a highly reliable retainer in which dimensional stability required for a retainer of an outer ring guide type, ductility required for a crown-type retainer, improvement in adhesion of grease with a poly-α-olefin oil or the like as a base oil, and deformation prevention at a high speed can be achieved. The rolling bearing includes at least an inner ring 1, an outer ring 3, a synthetic resin retainer 9, and a rolling element 7, in which the synthetic resin retainer 9 is formed of a polyamide resin composition including polyamide 410 and a reinforcing fiber material with a content of 0% by weight to 40% by weight.
