The invention relates to liquid compositions for use with hair removal devices comprising a metathesized unsaturated polyol ester for improved lubrication.

To provide a surface treatment agent capable of imparting excellent water/oil repellency, fingerprint stain removability, abrasion resistance and lubricity to the surface of a substrate. A surface treatment agent for a substrate, comprising a perfluoropolyether group-containing phosphate compound, a coating agent comprising the surface treatment agent and a liquid medium, and a substrate having a surface layer formed from the surface treatment agent or the coating agent.

A composition obtained by reacting an O,O-dialkyldithiophosphoric acid with a hydroxyalkyl acrylate or a hydroxyalkyl methacrylate, and reacting the product thereof with a dialkylphosphite provides good antiwear protection.

The invention relates to liquid compositions for use with hair removal devices comprising a methathesized unsaturated polyol ester for improved lubrication.

A method of utilizing a wellbore tool in a subterranean formation includes disposing a wellbore tool in a borehole. The wellbore tool has a first body and a second body. The first body is translated relative to the second body while exposing at least one surface of at least one of the first and second bodies to a lubricant comprising an organometallic compound, and a protective coating forms over the first body and/or the second body. The protective coating formed includes a metal originating from the organometallic compound. A tool for forming or servicing a wellbore includes a first body; a second body configured to translate relative to the second body; and a lubricant adjacent the first body and the second body.

Provided are a lubricating oil composition containing a base oil, a specific thiophosphate compound (A) and a molybdenum-based compound (B), which exhibits excellent wear resistance and has a low friction coefficient in a broad range of contact pressures ranging from high to low; and a precision reduction gear using the lubricating oil composition.

The present invention discloses with the development of ecofriendly and biodegradable lubricant formulation useful for micro electro mechanical systems and process thereof. The new generation Mineral oil free lubricant formulations were developed by esterification of polyols such as 2,2-dimethyl, 1,3-Propanediol, 2,2-diethyl-1,3-propane diol, and aliphatic di carboxylic acids like adipic and azelaic and with mono alcohol, using heterogeneous catalyst Indion 140 with cation exchange properties. The said formulation has a viscosity in the range of 31 to 47 cSt at 40 C., a high viscosity index of 139-196, pour point of approximately <39 C. with a multifunctional EP additive of recommended dose of 1.5-4%. These new generation lubricants exhibited excellent biodegradability, a high viscosity index, and a low pour point, a high flash point, good lubricity, good oxidative stability, very good protection, against wear, no evaporation loss, good adherence to metal, corrosion inhibiting characteristics and suitability for use with commercial additives. In addition the products are non toxic to the sewage bacteria.
