Latest Patents

Wharne's latest patents include innovative liquid bleach and detergent compositions. One of his notable inventions involves liquid compositions containing a perborate bleaching system that boasts improved chemical stability over existing systems. These compositions are prepared by suspending a salt of a superperborate in a non-aqueous liquid. The superperborate salts have an available oxygen content exceeding 16.1%, with an empirical chemical formula of the type Na.sub.x B.sub.y O.sub.z.nH.sub.2 O, where x ranges from 1 to 4, y from 1 to 5, z from 2 to 15, and n from 1 to 5. The ratio of x to y is maintained between 0.5 to 1.2:1. These compositions may also include surfactants, activators, and detergent auxiliaries, with preferred surfactants being nonionic. When surfactants are present, the compositions serve as bleach-containing liquid detergents, while in their absence, they can function as bleach additives or non-detergent cleaners.

Another significant patent involves concentrated liquid compositions containing a peroxygen compound. Wharne discovered that storable compositions containing both inorganic or organic peroxyacids and nonionic surfactants can be achieved by using particulate potassium-4-sulphoperoxybenzoic acid dispersed in the liquid nonionic surfactant phase. Additionally, these compositions can include a dispersed particulate water-insoluble builder such as zeolite or a water-soluble builder like STPP. A small amount of a chelating peroxidic stabilizer, such as dipicolinic acid or 1,1,1-hydroxyethylidene diphosphonic acid, is also preferable.
