Abstract
Liquid all-purpose preparations of the type containing anionic and/or nonionic surfactants, water soluble builders, and water-soluble solvents are significantly improved by the inclusion of a fat-dissolving agent consisting essentially of a terpene and a solvent based on completely or partially hydrogenated naphthalene.
Claims25
In a liquid cleaning preparation for removing fats and soil from hard surfaces of the type containing an anionic or nonionic surfactant or both;
- a water-soluble builder;
- and a water-miscible solvent;
- the improvement comprising a fat-dissolving agent consisting essentially of from about 0.25 to about 5.0% by weight of a terpene and from about 0.25 to about 5.0% by weight of a water-insoluble apolar solvent which is completely or partially hydrogenated naphthalene, and wherein the pH of the cleaning preparation is above about 7.
A liquid cleaning preparation for removing fats and soil from hard surfaces comprising:
- A. from about 1 to about 25% by weight of an anionic surfactant, a nonionic surfactant, or both of the foregoing;
- B. from about 0.1 to about 10% by weight of a water-soluble builder,
- C. from about 1 to about 15% by weight of a water-miscible solvent;
- D. from about 0.25 to about 5.0% by weight of a water-insoluble apolar solvent which is completely or partially hydrogenated naphthalene;
- and
- E. from about 0.25 to about 5.0% by weight of a terpene;
- wherein the percentages by weight are based on the weight of the liquid cleaning preparation.
