Title: Innovations in Detergents: The Contributions of Elfed H Evans
Introduction
Elfed H Evans, a prominent inventor based in Clwyd, GB, has made significant advancements in detergent technology. With a total of six patents to his name, his innovations have expanded the possibilities within the cleaning industry, particularly concerning the formulation of detergents.
Latest Patents
Among his latest patents, one notable invention is the granular detergent composition that includes soap noodles. This innovative detergent powder comprises soap-based noodles containing 2 to 15% free fatty acid and 1.5 to 5% inorganic salt, such as sodium chloride. The inclusion of free fatty acid enhances the dissolution rate of the noodles, while the inorganic salt counterbalances the softness of the soap composition, which can complicate noodle production.
Another significant contribution by Evans is his work on detergent compositions, notably a liquid surfactant composition that remains mobile at temperatures ranging from 20 to 80 degrees Celsius. This composition consists of up to 80% anionic surfactant (sodium or potassium alkylbenzene sulphonate and/or alkyl sulfate), up to 80% nonionic surfactant, and less than 10% by weight of water. This formulation allows for the spraying of the liquid composition onto a solid particulate absorbent material, effectively forming a detergent powder or its components.
