  • Chemically and physieo -chemically the varieties of soils and stains range the spectrum from primarily oily, through proteinaceous and carbohydrate, to inorganic, and detergent compositions have become more complex as formula- tors attempt to provide products which handle ail types, concurrently.
  • protease enzymes are commonly used in detergents for blood and gravy stains; amylase enzymes are used for carbohydrate stains; nonionic surfactants are used for hydrocarbon oils; and anionic surfactants and builders are used for particulate soil.
  • Bleach is used to chemically degrade stains that are not amenable to removal by less rigorous treatment .
  • Cosmetics are typically manufactured with great care, such that the clay and color bodies are i the form of very fine particles . , and are very t horoughly and completely mixed with,, and coated by, the oily material, which may be a hydrocarbon oil, silicone, lipid, or complex, mixtures thereof. While op- timai from the standpoint of the cosmetic formulator , the modern cosmetic product causes ma or problems for the detergent formulator,. since cosmetics constitute a mix of widely divergent soil types ⁇ oily, particulate, clay) all in intimate admixture and often brightly colored.

  • solvents of the type employed in this invention as grease and oil removal ingredients in cleaners of various types is well-known.
  • the use of such solvent is not without its one set of difficulties. Many of. the solvents which can. find utility in addressing oil stains have no effect or even a detri- mental effect on non-oily stains, typically cussing smearing. In some cases the solvents used may remove a stain from a first area only to redepos.it it in. a second area or other the entir item being cleaned. Moreover some solvents can provide a barrier to a stai such that components of a detergen formulation, present in the aqueous phase thereof are unable to contact a stain.
