DuPont: Tynex® Natrafil™ filaments provide an innovative alternative to natural hair

Based on the company’s expertise in material and technology, DuPont Filaments is launching a new generation of synthetic filaments for blush brushes with the touch and feel of natural bristle. DuPont™ Tynex® Natrafil™, samples of which are available for customers as from November 2007, are machine produced for consistency and quality and provide benefits versus their natural counterparts in terms performance, behavior and cost.

Tynex® Natrafil™ filaments have been developed by DuPont for use in blush brushes in loose- and pressed-powder applications, as well as in professional applicators of liquid make-ups, such as eyeliners and lip-liners. The tapered filaments are made from a polymer composite and are produced using a unique tipping technology to improve their softness and enhance their pick-up of powders or make-up. They provide significant benefits in terms of swelling behavior, stiffness retention in moisture and bend recovery versus natural hair or other synthetic alternatives such as pure polyester, polypropylene or nylon, and are also competitively priced in comparison. Tynex® Natrafil™ filaments will be commercially available in a range of colors (natural/white, brown or gold) and diameters (between 3 and 4 mils) as of January 1st, 2008, although samples will be available for customer testing from November onwards.

One of the first customers to work with the new filaments is the Japanese company Shinohara Co., Limited. Combining its knowledge and expertise as a leading cosmetic brush manufacturer with DuPont’s material knowledge, Shinohara Co. was involved in the development and refinement of the new product. According to Takahiro Kasai, vice president of Shinohara Co., the Tynex® Natrafil™ filaments offer a genuine and timely alternative to those made from natural hair. “The brush industry has traditionally dealt with natural animal bristle for cosmetic brushes. However, when it has come to the production of large volumes at consistent quality, we have faced standardization issues due to variations in the bristles,” he explains. “We had always hoped that a synthetic alternative with the touch and function of natural hair could be found, and it is our pleasure to confirm that DuPont has achieved this milestone – an accomplishment for which we hold them in high regard.”

The new generation of Tynex® Natrafil ™ filaments complements the existing range of premium filaments available from DuPont under the Tynex® brand for a variety of cosmetic applications. Offering a vast number of variations in flexibility, stiffness or softness, they have earned a reputation for meeting the most demanding requirements of cosmetic brush makers. From mascara brushes engineered for optimal pick-up and smooth application, to eyeliner-, lip- and blush brushes with multiple colors and optional properties, cosmetic brushes made with DuPont filaments help products deliver maximum customer satisfaction.

The regional operating companies that make up DuPont Filaments are DuPont Xingda Filaments Co., Ltd. in Wuxi, China; DuPont Filaments-Europe BV in Landgraaf, The Netherlands; and DuPont Filaments-Americas, LLC in Wilmington, Delaware, USA.
