The GC3 Preservatives Challenge sought submissions on new broad spectrum or single action chemical agents on gram-positive bacteria, gram-negative bacteria, yeast and mold, as well as preservative boosters.
Challenge sponsors and participants represented the entire value chain, with 11 consumer packaged goods companies, two major retailers and five suppliers: Babyganics, Beautycounter, Beiersdorf, Colgate-Palmolive, Johnson & Johnson Consumer, Kao USA, Method – People Against Dirty, Procter & Gamble, Reckitt Benckiser, SC Johnson, Unilever, Target, Walmart, Dow Microbial Control, Lonza, Schülke, Symrise, and Thor, as well as the Environmental Defense Fund and the Minnesota Pollution Control Agency.
The challenge drew 48 submissions that were judged by a panel of expert microbiologists, product formulators, and safety experts from sponsoring CPG companies and others. After the submissions were formulated into three simple products, the preservative technologies were evaluated for safety and efficacy. Innovators received the results from the evaluations and feedback from the judges.
