Novolyte offers a number of low toxicity alternatives to halogenated and other toxic solvents in various cleaning formulations for household, industrial, and institutional cleaning applications.
Formulating High-Performance Cleaners with Aprotic Novolyte Green Solvents
Formulators have long realized that the incorporation of an Aprotic solvent will increase the performance of cleaning solutions and paint removers—including those that are water-based.
Novolyte 1,3-Dioxolane is a low cost, very effective cleaning solvent for paint stripping and graffiti removal. Novolyte dioxolane is being used for cleaning and degreasing products, including N-propyl bromide based degreasers. Dioxolane also has the advantage of working as an inhibitor to prevent NPB corrosion on soft aluminum surfaces.
Novolyte Proglyme is often chosen by formulators due to its ability to dissolve grease and oil. A recent patent application showed the benefit of Proglyme to remove paint and overspray (US 2010/0041581, assigned to Lubrication Technologies, Inc.). Their new formulations are non-corrosive without the use of aromatics. These formulations also offer alternatives to products on the market formulated with halogenated solvents, which often include caustic materials.
As an example of how glymes are used in electronics cleaning applications, in U.S. Patent 5486314, CFCs were replaced by glycol diethers.
Proglyme is non-HAP, and as a propylene based or P-series glycol, has an excellent tox profile. With its 175°C boiling point, Lube-Tech was able to claim formulations with low vapor pressure (less than 0.8 mmHg at 20°C).
