DuPont Tate & Lyle Bio Products Collaborates with RML Incorporated to Develop Bio-Based Solution for Personal Care Products

Wilmington, DE (PRWEB) May 06, 2013

DuPont Tate & Lyle Bio Products Company LLC is proud to announce that it has partnered with RML, Inc. in creating a new line of alternative preservatives called PolyGuard. The PolyGuard line features the proprietary ingredient Zemea® propanediol.

Zemea® is a natural, 100 percent bio-based ingredient made from corn sugar through fermentation and developed for use in the cosmetics and personal care market. It is a high-performance, environmentally friendly sustainable alternative to petroleum-based glycols and glycerin, where the product’s lack of skin irritation, improved moisturization and excellent aesthetic properties are benefits. Zemea® is approved as a natural ingredient by Ecocert and the Natural Products Association; it is certified 100 percent bio-based by the U.S. Department of Agriculture and has both Kosher and Halal certifications.

RML designed its new preservative line, PolyGuard, capitalizing on the ability of Zemea® to boost preservative efficiency along with its proven lack of irritation in cosmetic and personal care products in combination with the natural preservative, e-polylysine, which is derived through the fermentation of bacteria. The PolyGuard line has two preservative blends – PolyGuard BA and PolyGuard CG. PolyGuard BA combines Zemea® with other ingredients of natural origin – e-polylysine and benzyl alcohol – allowing for natural preservation in a safe and effective manner. PolyGuard CG draws on RML’s experience in the marketplace producing caprylyl glycol based preservative systems by combining Zemea®, e-polylysine and RML’s domestically produced and exceptionally pure caprylyl glycol. These materials are exclusively manufactured for RML by Hampford Research Incorporated.

"The innovators in the cosmetic and personal care industry are increasingly demanding functional ingredients of natural origin that improve product performance," said Pete Colombo, account executive for DuPont Tate & Lyle Bio Products. "We are pleased RML Incorporated chose to collaborate with DuPont Tate & Lyle Bio Products for the development of the PolyGuard preservative systems featuring Zemea® propanediol."

Formulators should consider PolyGuard BA for preservation in their natural products. PolyGuard BA provides broad-spectrum preservation in a clear liquid with little to no odor allowing for use in a wide range of natural personal care materials. While not derived entirely from natural materials, PolyGuard CG provides formulators with a preservative that is an alternative to parabens and formaldehyde releasers using the long-standing effectiveness of caprylyl glycol based systems. RML would like to thank Irwin Palefsky of Cosmetech Laboratories Incorporated and John Yablonski of Bio-Control Service Group Incorporated for their assistance and advice in formulation and preservative design.

RML, Incorporated, headquartered in Sandy Hook, Conn., is a certified minority and family owned and operated business established over 25 years ago. RML prides itself on providing high-quality, innovative preservative systems and other raw materials to the cosmetic and personal care industries. RML has long-standing customer relationships based on superior service, versatility and innovation. For more information, visit
