    Abstract: Improved separation of emulsified hydrophobic organic soils can be obtained from aqueous effluents using an amphoteric dicarboxylate surfactant material in combination with cationic destabilizer or floeculent materials. Such a treatment in combination with an acidic pH adjustment causes the rapid separation of hydrophobic organic soils from the aqueous stream, the treated aqueous stream is environmentally compatible.Improved laundry detergents comprising an organic amphoteric carboxylate surfactant and selected nonionic surfactants provide both cleaning for fiber and fabric containing items soiled with substantial quantities of hydrophobic soil. The pH of an effluent generated in such cleaning processes can be adjusted to an acid pH and treated with a cationic material causing a break that permits rapid and substantially complete separation of the hydrophobic organic soils from the effluent. Residual concentrations of organic soil in effluent water can be less than 250 ppm and can be as low as 10 ppm.

  • Patent number: 5712232
    Abstract: An aqueous liquid cleansing composition, packaged in a foamer container, said composition comprising:(A) from 5 to 50% by weight of an anionic carboxylate surfactant; and(B) from 0.1 to 5% by weight of a salt.The aqueous liquid cleansing composition of the present invention shows an extremely low viscosity increase at a low temperature and can be easily pushed out from the foamer container even at a low temperature thus giving uniform foam. It is particularly suitable for a skin cleanser.

  • Patent number: 5710120
    Abstract: Stable, silicate-free, soft metal safe, alkaline cleaners are provided. The cleaners comprise calcium ions and surfactants containing hydroxyl and/or carboxylic acid groups or a combination thereof, wherein the total of the two functionalities in each surfactant is greater than or equal to 2, and alpha-hydroxy carboxylic acids. It has been surprisingly discovered that alpha-hydroxy carboxylic acids such as tartaric acid, are capable of keeping calcium ions in an alkali solution. The cleaners may also comprise nonionic surfactants to provide wetting, detergency, and foamability where required, anionic surfactants as viscosity enhancers in the case of high retention cleaners, and solvents such as alcohols, glycol ethers, or hydrotropes to enhance solubility of the system. The alkaline cleaners are safe to use on soft metal surfaces and equipment commonly found in many industries, without the presence of silicate which is normally used as a corrosion inhibitor.

  • Patent number: 5705472
    Abstract: An aqueous cleaning composition having a pH of about 6 to about 8 and comprising a solution of the following ingredients: water, an organic solvent and an imidazoline-based cationic surfactant, each present in an amount effective to dissolve adherent soils from a substrate; and a nonionic surfactant in an amount sufficient to maintain said cationic surfactant in solution; and also a weak organic acid in an amount sufficient to impart to the composition said pH; wherein said composition is substantially free of any material which has an ozone-depletion factor of greater than about 0.15 and wherein said composition is substantially free of any material which would tend to form a solid with any of the ingredients comprising the composition, and its use to clean metallic and non-metallic surfaces.

  • Patent number: 5705470
    Abstract: A substantially homogeneous sprayable cleaning gel composition which is substantially free of suspended encapsulated particles exhibits extended dwell time when sprayed on to a surface as compared to a low viscosity spray cleaner. The extended dwell time and anti-static properties of the sprayable cleaning gel composition give rise to several benefits and advantages. The sprayable cleaning gel composition housed in a spray applicator is usable to clean surfaces at any angle. A preferred method of cleaning surfaces is also described.
