Abstract:
La présente invention concerne l'utilisation d'une émulsion eau dans huile (e/h) ou huile dans l'eau (h/e) composée d'une phase huileuse comprenant une ou plusieurs huiles d'origine végétale brutes ou raffinées, au moins un tensio-actif émulgateur non ionique et/ou anionique, et une phase aqueuse comprenant au moins un phyllosilicate, en tant que lubrifiant pour dispositif mécanique, caractérisé en ce que l'émulsion eau dans l'huile ou huile dans l'eau est fluide à température ordinaire.
Abstract:
The present application relates to citric acid-modified polypropylene glycols which are represented by Formula (1) or, as well as compositions comprising such compounds. The polypropylene glycol-based compounds of the invention are useful as additives and in particular as emulsifying agents in e.g. cooling lubricants, as release agents, as well as additives for cosmetic products.

Abstract:
The invention relates to nanoparticle compositions comprising a graphene-based material and preparation process thereof. The invention also relates to the use thereof as a lubricant additive to improve tribological performance, in particular to improve anti-friction and anti-wear performance on metal parts, and to a lubricant composition comprising these nanoparticle compositions.
Abstract:
The invention concerns a metalworking fluid formulated starting from natural oils coming from renewable sources, and free from amines, formaldehyde, boron and chlorine, which can be used as it is, after emulsifying in water, or is already pre-emulsified and is to be simply diluted with water. At the end of its life cycle, the specific formulation of the metalworking fluid allows a simple and economical treatment for breaking of the exhausted emulsion and treating the resulting oily and aqueous phases.
Abstract:
The present invention relates to a controlled release gel with an ashless component and defined ash-producing component. Further, the invention relates to the use of a controlled release gel with a controlled level of ash-producing (i.e., metal) components for delivery of additives into lubricants wherein the gel has reduced ash and SAPS producing components.
Abstract:
Novel oil-in-ol emulsions and methods of lubrication using the same are provided. The lubricants are stable emulsions of carrier fluid and high viscosity fluid that display superior properties related to lubricating film thickness and reduced shear strenght.
Abstract:
The present invention concerns an aqueous alkaline composition comprising at least one glycolipid biosurfactant and at least one non-water soluble lubricant, and its use in industrial processing fluids. Preferably the present invention concerns an aqueous alkaline composition comprising at least one sophorolipid, at least one rhamnolipid, at least one non-water soluble lubricant, and at least one alkalinity agent, and its use in metalworking fluids.
