Abstract

Performance of short chain ethoxylated dioxolanes, in particular 2,2-Dimethyl-1,3-dioxolan-4-ylmethanol ethoxylated, as cleaning agents on detergent formulations, like laundry detergent compositions, has been studied and appears to be particularly satisfying. Those molecules have also good performances as cleaning agent in multipurpose cleaner compositions, degreaser compositions, hard surfaces cleaner compositions, among others.

Description

The constant search for sustainable alternatives in several fields of the chemical industry, such as mining, pharmaceutical, agro, paints & coatings, leather, home & personal care, construction, electronics, etc, led to development of solvents that meet the three pillars of sustainability (economical, environmental and social). Such solvents present competitiveness, very good performance in the application, and additionally low toxicity to humans and environment. One application where those solvents can be used is as cleaning agents in different types of products, like multipurpose cleaners, kitchen cleaners, bathroom cleaner, and many others, including laundry detergents, where they are used to clean different kinds of fabric.

The act of cleaning is to remove an undesired material from a surface. Different kinds of material can be soils that are hold into the surface due to adhesion forces that can be either very strong, like covalent bonds, or relatively weak, like van der Waal’s interactions. Independently of the type of interaction, for the cleaning process to be effective, there is the need to apply energy enough to overcome those adhesion forces. Some of the mechanisms that produce this kind of energy, allowing the cleaning effect are: displacement and dispersion of the soils, dissolution of it, reaction and mechanical removal.

Typical soils can be divided into liquid and solid. The most common liquid soils are hydrocarbon oily based, while solid soils are usually help in place by capillary action with oily soils. Consequently, by cleaning the oily soils, the solid soil comes off as well. Depending on the size and type of soil, the cleaning mechanism done by solvents can be: soils roll up, entropic swelling or solubilization. The first one is typical of light soils and small amphiphilic solvents and can happen when the solvent promotes the removal of the soils from the surface. The second one is common for medium to heavy soils and moderately sized solvents, which interacts with both the water and the soils reducing the viscosity of the soils as well as the surface tension of the water, promoting the formation of softener soils that are easily cleaned by emulsification with surfactants. Last but not least, soils that are soluble in both water and the solvent can be cleaned by solubilization, once the soils simply dissolves into the solvent being used, allowing its removal from the surface.
