Product Description:

ZONYLŪ is the trade name of a series of fluorosurfactants which have either anionic or nonionic functionality. They have much greater wetting power than non-fluorinated surfactants, and are stable in harsh environments -both thermal and chemical. In most personal care product formulations these efficient surface-active agents are effective at very low concentrations (50-1000 ppm or 0.005-0.1%) - making them cost-effective additives that deserve consideration. Most have been formulated as liquids for ease of handling and dilution.

Product Properties:

- Surface Tension
Aqueous solutions of fluorosurfactants can achieve surface tensions as lOW as 15 dyneslcm at 0.005% vs. a typical 30 dyneslcm at 1% concentration for commonly used hydrocarbon surfactants. This value-in-use advan-tage can be used in many situations to improve your product - in places where room is needed in the formulation for active ingredients, where you wish to minimize residues, or where the improved wetting power is of value. Further, there are a number of situations where synergy has been observed between fluorosurfactants and hydro-carbon- or silicone-based surfactants. Replacing a portion of the surfactant in your current formulation with the alternative fluorosurfactant can yield unexpected benefits.

- Oleophobicity
Unlike hydrocarbon or silicone-based materials, ZonylŪ fluorosurfactants are surface active in nonaqueous media, providing extra wetting and leveling power in solvent-based applications; e.g., nail polishes, polish remover, and astringents. ZonylŪ fluorosurfactants, once adsorbed onto a surface, render that surface oleophobic; at least one manufacturer has capitalized on this phenomenon (US pat. nos. 3,993,744 and 3,993,745).


Unique characteristics
The great differences in properties between ZonylŪ Fluorosurfactants and hydrocarbon/silicone surfactants can be attributed to the fluorocarbon chain. The fluorocarbon portions of these molecules give the surfactants an extreme tendency to orient at air interfaces. In applications where such surfaces are created -- foaming, spraying, and coating, for example -- the fluorinated surfactant will enhance product performance, even at vanishingly small addition levels.

The stability of ZonylŪ Fluorosurfactants in harsh environments can be exploited in formulations (e.g., hair relaxer solutions, permanent waves, or permanent dyes) where strong alkali or powerful oxidants can break down ordinary surfactants. This can increase product efficacy, and increase shelf life.

The surfactant characteristics of ZonylŪ fluorosurfactants may complement the other surfactants in your formula-tion. Hydrocarbon and silicone surfactants are excellent at reducing interfacial tension between condensed phases (liquids, solids, emulsions). Fluorosurfactants excel at reducing air-liquid and air-solid interfacial tensions. A mixture of the two types of surfactants in your formulation could deliver 'the best of both.'


ZonylŪ Fluorosurfactants in your formulation:
Technical information, and formulation suggestions are available through our technical service group, located in Deepwater, NJ. ZonylŪ fluorosurfactants have seen widest use as wetting, leveling, and foaming agents in aque-ous and solvent media; however, the substantivity of ZonylŪ fluorosurfactants adsorbed on surfaces has led to creative uses for these materials as conditioners, antistats, oleophobes, and protectants. There's more! DuPont sells a complete line of fluorinated intermediates to those who wish to design their own fluorinated products.
