Abstract

The present invention relates to an aqueous based, solvent free cleaning or degreaser composition, comprising (a) alcohol alkoxylate with a fatty alcohol moiety, (b) polyoxyalkylene block copolymer, and (c) a fatty alcohol having an oxyethylate moiety.

Description

  • 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., SU T56873; and Dudesek et al., CS 220985.

Finally, residual phosphorous is an environmental concern. The nominal amount of alkali builder also results in a caustic solution.

  • Finally, US 5,501,816 (US '816) discloses ternary surfactant blends comprising: alcohol alkoxylate with a fatty alcohol moiety, alkyl phenol alkoxylates and alkyl oxyethylate. US '816 also discloses that the addition of polycarboxylate polymers enhances the efficacy of the degreaser compositions.
