Title: John Petchul: Innovator in Microemulsion and Gel Technologies
Introduction
John Petchul is an accomplished inventor based in Lake Orion, MI (US). He has made significant contributions to the field of gel compositions and microemulsions, holding a total of 4 patents. His innovative work focuses on creating effective formulations with antiseptic and bleaching properties.
Latest Patents
Among his latest patents is a process and composition for a microemulsion gel that possesses both bleaching and antiseptic properties. This gel is formulated by combining a water phase, which includes water and propylene glycol, with an oil phase that typically consists of various surfactants, an emollient, and oil. In its preferred embodiment, the oil phase features a polyethylene glycol ether of isocetyl alcohol, specifically Isoceteth-20, along with a polyethylene glycol ether of oleyl alcohol, known as Oleth-2, and a polypropylene glycol ether of stearyl alcohol, referred to as PPG-15 stearyl ether. The water phase may also include sorbitol, while the oil phase can utilize mineral oil. The two phases are heated separately before being combined and mixed. Following this, hydrogen peroxide is added, and the mixture is cooled to form a gel, with the option to include fragrance.
Another notable patent involves an isopropyl alcohol gel designed for use as a rubbing composition with antiseptic properties. This gel comprises a polymer, water, isopropyl alcohol, and a polymer neutralizing agent. The polymer is initially dispersed in water to create a thick phase, with a preferred choice being a carbomer resin that hydrates to form a slightly gelatinous mass. Isopropyl alcohol is then added to this polymer-water phase, allowing sufficient time for hydration. A neutralizing agent, preferably tetrahydroxypropyl ethylenediamine, is subsequently introduced to neutralize the polymer's activity, resulting in a homogeneous heavy clear gel.
