DuPont Tate & Lyle Bio Products Company LLC has partnered with RML Inc. to launch PolyGuard, a new line of alternative preservatives that combine polylysine with DuPont Tate & Lyle's Zemea propanediol as a preservation booster.
PolyGuard utilizes Zemea to boost preservative efficiency 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 (INCI: Polylysine (and) Propanediol (and) Benzyl Alcohol) and PolyGuard CG (INCI: Polylysine (and) Propanediol (and) Caprylyl Glycol).
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 of 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. Both PolyGuard preservatives also function as emollients. They are recommended at 1% in formulations and are soluble in water and isopropanol.
Zemea is a natural, 100% bio-based ingredient made from corn sugar through fermentation and developed for use in the cosmetics and personal care market. It is an 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% bio-based by the U.S. Department of Agriculture and has both Kosher and Halal certifications.
The Cosmetics & Toiletries Complete Cosmetic Chemist Training Program offers an online, video-based course dedicated to teaching new and seasoned formulators about natural formulation and how to choose genuinely natural or organic products.
Registration for this course also includes a free copy of Anthony C. Dweck's book, Formulating Natural Cosmetics.
