US Patent No. 9,770,609 B2; Neat Feat Products Limited, Auckland, New Zealand, has been awarded a US patent for a topical formulation that treats skin. It contains a film-forming polymer, humectant, preservative and water. The urea has a molecular formula H2NCONH2. The film-forming polymer comprises polyoxypropylene(17) isophorone diisocyanate and dimethylol propionic acid copolymer (PPG-17/IPDI/DMPA copolymer).
The ingredients are combined such that the preservative protects the formulation against bacterial invasion, the humectant assists the formulation to retain water, and the water and film-forming polymer enable the urea to be applied to human skin such that the urea sits on the skin as a stable film and is gradually absorbed to alleviate dryness or cracking. In addition, the film is waterproof.
