The invention relates to the formulation and application of water based predominantly pH neutral microemulsions and microemulsion forming surfactant systems essentially comprising a surfactant or surfactant ~ end, lactates) - esters) of lactic acid - and water / brine and optionally solvent. Uniquely the formulations are acid and caustic free and also do not make use of alcohol, glycol and glycol ether components in the systems as co~ surfactant, co-solvent or mutual solvent. In particular the invention relates to the methods and the application of this microemulsion technology for use in industrial hard surface cleaning applications especially the inks and printing industries and the oil and gas industry. In addition the formulations can be used in the production of microemulsion based drilling muds (which may or may not be Oil Based Muds - OBMs) and they may be used to enhance the drill cuttings slurrification processes for re-injection purposes or for facilitated cuttings transport.
L~invention concerne la formulation et l~application de microémulsions principalement à pH neutre à base d~eau et de systèmes à tensioactifs formant des microémulsions comprenant essentiellement un tensioactif ou une extrémité tensioactive, des lactates, des esters d~acide lactique et de l~eau/de la saumure et un solvant en option. Les formulations sont exemptes d~acide et de soude caustique, et elles n~utilisent pas de composants d~alcool, de glycol et d~éther glycolique dans les systèmes comme co-tensioactif, co-solvant ou solvant mutuel. En particulier, l~invention concerne les procédés et l~application de cette technologie à microémulsion pour des applications industrielles de nettoyage de surfaces dures, surtout dans les industries de l~encre et de l~impression de même que l~industrie du pétrole et du gaz. En outre, les formulations peuvent s~employer dans la production de boues de forage à base de microémulsion (qui peuvent être ou non des boues à base d~huile) et elles peuvent servir à améliorer les procédés d~abattage hydraulique de débris de forage à des fins de réinjection ou pour faciliter le transport des débris.
