  • Patent number: 5698509
    Abstract: A pourable, homogenous, abrasive aqueous detergent composition, suitable for cleaning hard surfaces contains detergent active compound which is preferably a mixture of anionic and nonionic detergent active compounds, and a water-soluble salt in an amount sufficient to provide undissolved particles which act as an abrasive. The composition has an apparent viscosity which is sufficient to maintain the particles of salt in suspension during storage while ensuring that the composition remains pourable.

  • Patent number: 5616549
    Abstract: The present invention provides a solvent mixture comprising n-Propyl bromide, a mixture of terpenes and a mixture of low boiling solvents, and a method for cleaning an article (e.g., an electrical, plastic, and metal parts) in a vapor degreaser using the solvent mixture. The solvent mixture of the present invention is non-flammable, noncorrosive and non-hazardous. In addition, it has a high solvency and a very low ozone depleting potential. Thus, using the solvent mixture of the present invention, oil, grease, rosin flux and other organic material can be readily removed from the article of interest in an environmentally safe manner.
