Muck Daddy™ Named Official Hand Cleaner of Pirelli World Challenge

WC Vision LLC, producers of the Pirelli World Challenge ("PWC") racing series, and Amyris, Inc. (Nasdaq:AMRS), the industrial bioscience company, today announced a new relationship whereby Amyris's high-performance cleaning brand, Muck Daddy™

(www.muckdaddy.com), has been named the official hand cleaner of the PWC racing series.

Muck Daddy, developed by Amyris's biochemists for more than decade, is a breakthrough line of high-performance cleaning products based on Amyris's proprietary Myralene™ 10 solvent, a revolutionary ingredient positioned to replace harsh petroleum- and limonene-based solvents. Muck Daddy's first release, the High Performance Hand Cleaner (available with and without pumice), is USDA Certified Biobased and formulated with industrial workers' needs and wellness in mind.

Muck Daddy's Scrubbing Wipes, another innovative product in the brand's line, can be used to clean oily, greasy dirt off hands as well as tools, parts and surfaces. Muck Daddy hand cleaners also contain Amryis's premium skincare ingredient, Neossance® squalane, to moisturize and improve the condition of hands.

In 2016, the Pirelli World Challenge enters its 27th year of competition following its most competitive racing season in 2015 with series Drivers' Champions representing six different manufacturers: Johnny O'Connell (Cadillac), Frankie Montecalvo (Mercedes-Benz), Colin Thompson (Porsche), Michael Cooper (Chevrolet), Corey Fergus (Porsche), Jason Wolfe (Kia) and Johan Schwartz (Chevrolet). Manufacturer titles went to Porsche (GT), Ford (GTS), Mazda (TC) and Honda (TCA).

"Bringing our Muck Daddy™ cleaning products to the Pirelli World Challenge is a perfect fit for our brand," said Jason Voogt, Vice President, Performance Materials, at Amyris. "Based on our new, highly-effective, bio-based solvent, Myralene™ 10, our products work under the most extreme conditions where speed and performance are critical in a top racing series such as the Pirelli World Challenge. The PWC racing teams can use our products without exposing themselves to other petroleum-based cleaning products that can stink, sting and tear up their hands. Muck Daddy™ is a perfect brand for the PWC racers."

"We are very excited to bring Amyris's high-performance cleaning brand, Muck Daddy™, to the Pirelli World Challenge in this new relationship," said Greg Gill, WC Vision President and CEO. "Muck Daddy™ is a leader in its category with its eco-friendly and effective cleaning performance. We believe Muck Daddy™ will be a tremendous asset to our participants as well as our fans. We look forward to a long relationship with Muck Daddy."

The 2016 Pirelli World Challenge season kicks off on March 3-6, 2016 at the Circuit of the Americas in Austin, Tex., with a sensational headliner weekend featuring all seven PWC classes in action as well as the six-hour SRO Blancpain Endurance GT feature.
