The present invention relates to an aqueous based solvent free
cleaning or degreaser composition comprising at least two non-ionic
surfactant components which effectively clean oils and
greases from a variety of surfaces.
-
The demand for cleaning and degreasing formulations for a myriad
of cleaning applications is well known. Target applications range
from the light cleaning of printed electronic circuit boards to
the cleaning of used automotive parts. Many formulations for
these purposes contain varied levels of volatile solvents to efficiently
degrease surfaces. Many heavy duty degreasing operations
use heated solvent baths.
-
Recent concerns for environmental and toxicological effects of
solvents and solvent baths have caused a full search for aqueous
degreasing systems without solvent. Few surfactant based systems
have been successful without at least a minor amount of solvent,
for the dual purpose of cleaning and defoaming. Hence, industrial
and institutional cleaning operations that require degreasing
must reconcile their desire to be socially conscious with the
need to remain effective.
-
The use of glycol ether solvents or cycloalkanes in cleaning
compositions, in combination with anionic and/or nonionic
surfactants, are known in the art. Examples of such systems may
be found in Wittel et al., EP 376367; Kao Corporation,
JP 3062096; Lyubarskay et al., SU 1300041; Bedo et al.,

combined with a necessary amount of alkali builder of varying
types. However, the phosphate moiety is responsible for
increasing the generation of foam. Finally, residual phosphorous
is an environmental concern. The nominal amount of alkali builder
also results in a caustic solution.
