Dirt and soil on shiny surfaces, particularly on glass, are highly noticeable to consumers. Glass cleaners, with a market size of about $200 million in 2016,1 are generally a combination of surfactants, cleaning agents, solvents and other components such as fragrances and dyes. Hydrocarbon surfactants, such as sodium dodecyl sulfate, are commonly used in these cleaners. However, they tend to leave a hazy residue on glass after cleaning, also known as streaking. Also, they create foam, which is perceived by consumers as requiring more work to clean. Various commercial glass cleaners claim streak-free cleaning, which is difficult to achieve. Therefore, it is highly desirable to have surfactants in glass cleaners that can emulsify greasy soil and that can be easily removed without leaving a residual streak, thus providing a clean, streak-free and glossy surface.
Fluorinated surfactants (fluorosurfactants) are a high performing class of surfactants, due to their effectiveness at reducing surface tension and their short fluorocarbon chains (C2-C6) that don’t foam as much as hydrocarbon counterparts. Conventional fluorosurfactants with a linear chain of 6 flu
