  • Patent number: 4131585
    Abstract: A novel leveling agent for self polishing dry-bright floor polishes having the following general structure is described: ##STR1## where R is either a non-linear aliphatic hydrocarbon or mixture of hydrocarbons containing 8 to 15 carbon atoms or an alkylbenzene moiety containing 8 to 12 carbon atoms in the alkyl chainA is either Oxygen or Sulfur atomR.sub.1 is either Hydrogen atom or CH.sub.3R.sub.2 is either Hydrogen atom or CH.sub.3a and b are small numbers or average numbers totaling no more than about 7 so that the solubility of the compounds is less than about 0.4% in water at room or application temperature, but when R is alkylbenzene moiety, A is oxygen atom only and R.sub.1 and R.sub.2 are hydrogen atoms only.

  • Patent number: 4074970
    Abstract: Level dyeings of synthetic fibers with cationic dyestuffs is achieved with the use of surface active agents having the general formula: ##STR1## where R is selected from the group of aliphatic hydrocarbons containing about 8 to 22 carbons atoms, mono- and di-alkylbenzenes where the alkyl chains contain about 8 to 12 carbon atoms each, B is selected from the group of --CH.sub.2 --, Oxygen atom and Sulfur atom n is a number ranging from zero to about 4 R.sub.1, R.sub.2 R.sub.3 contain at least one cyclic or heterocyclic structure and together contain no more than one hydroxyl group A is a water-solubilizing anionX = (ch.sub.2).sub.a X.sub.1 = (CH.sub.
