Latest Patents
Demangeon's latest patents include a concentrated stable nonaqueous fabric softener composition. This innovative formulation utilizes hexylene glycol, either alone or in combination with a lower alkanol or another glycol or glycol ether. This composition serves as a non-aqueous liquid carrier for cationic fabric softeners, particularly quaternary ammonium and imidazolinium cationic compounds. The resulting concentrated fabric softener compositions can contain up to 60% by weight of the cationic compound and may also include up to 15% by weight of a nonionic surfactant. These concentrated compositions are designed to disperse easily in cold water and can be conveniently dispensed from automatic dispensers.
Another significant patent is for a built bleaching detergent. This composition features a water-soluble inorganic percompound, such as sodium perborate, along with an alkali metal builder salt like pentasodium tripolyphosphate. It also includes a water-soluble organic builder salt, such as trisodium nitrilotriacetate, and an organic detergent like sodium linear higher alkyl benzene sulfonate. The effectiveness of this bleaching detergent is enhanced by the inclusion of a specific concentration of a water-soluble copper salt, such as copper sulfate hydrate, which ensures a desirable proportion of copper ions in the solution during normal use.
