  • Patent number: 4477361
    Abstract: It has long been the practice to incorporate bactericides, fungicides and virucides in detergent compositions. But in such detergent modifications if the antimicrobial is washed off as the hands or other surfaces are rinsed, the effectiveness of the detergent is greatly reduced. The composition should be absorbed onto the skin or other surface being washed, leaving a film which resists removal by running water. This is termed substantivity. Cinnamon oils and similar antimicrobial cinnamic compounds have been in soaps but they rinse off. A cinnamic compound-containing antimicrobial surfactant is provided herein which is rendered substantive to the surface being washed.

  • Patent number: 4448703
    Abstract: Combinations of carboxylic solubilizers, made by reaction of an acylating agent with an N-(hydroxyl-substituted hydrocarbyl) amine and surfactants are useful in incorporating oil-soluble, water-insoluble functional additives into aqueous systems. Typical solubilizers are made by reacting an alkyl-substituted succinic anhydride containing about 12 to about 500 carbon atoms with an alkanol amine such as diethyl ethanol amine. Typical surfactants are non-ionic hydrophilic surfactants such as ethoxylated phenols and ionic surfactants of both the anionic and cationic type. Typical functional additives are anti-wear, extreme pressure and load-carrying agents such as dithiophosphates. The aqueous systems formed with the aid of such combinations are useful, for example, as water-based hydraulic fluids.
