Honeywell Partners With Metabolix to Develop Marine Biodegradable Ingredients for
Personal Care Products
New Asensa®
ingredients will help Honeywell meet increasing demand for biobased, marine biodegradable ingredients in
exfoliants and other personal care products
CAMBRIDGE, Mass., March 3, 2015 (GLOBE NEWSWIRE) -- Metabolix, Inc. (Nasdaq:MBLX), an advanced biomaterials
company, announced today that it has entered into a global, exclusive commercial and technology alliance with Honeywell to
offer new marine biodegradable biopolymers for use in cosmetics and personal care products.
Through the alliance, Metabolix's Mirel® polyhydroxyalkanoate (PHA) biopolymers will be developed as part of Honeywell's
Asensa®
line of personal care additives to help address pending legislation in the U.S. focused on replacing synthetic, non-
biodegradable microbeads, as well as global demand for biobased and biodegradable alternatives. This technology is intended
to meet increasing regulatory and other requirements around the world for personal care microbeads that biodegrade in
marine and fresh water environments. Using applicable ASTM test methods, the marine biodegradability of Mirel PHA
biopolymers has been shown to be similar to that of cellulose and paper, and is faster than other commercially available
biodegradable polymers.
"Honeywell's alliance with Metabolix will help us meet increasing consumer demand for environmentally friendly personal care
ingredients," said Heidi Lebel, global business manager for Honeywell's personal care business. "We look forward to offering
new Honeywell Asensa solutions based on Mirel PHA biopolymers that will deliver great exfoliation performance that is gentle on
both the skin and the planet."
"With Honeywell's material science expertise and market channels, and Metabolix's history of innovation in sustainable
biopolymers, we hope to see a range of new Asensa ingredients introduced to the market through this alliance," said Max
Senechal, vice president, strategy and commercial development for Metabolix. "We are excited to work with Honeywell to bring
the benefits of Mirel PHA biopolymers that have been shown to be biodegradable in soil, marine and fresh water environments
to the personal care market."
