Research Project: Safer Natural Preservatives for Home Care and Cleaning Products

Location: Bioproducts Research

Project Number: 2030-41000-054-08-T
Project Type: Trust Fund Cooperative Agreement

Start Date: Nov 1, 2015
End Date: Oct 27, 2017

The ultimate goal of this project is to develop quick microbial screening tools for safer preservative options for products. Specific goals include: 1. Develop and qualify rapid methods for mold and bacteria screening. 2. Evaluate preservative candidates based on rapid through put models developed above. 3. Propose and test combinations to screen broad spectrum efficacy. 4. Determine short list candidates and combinations that meet specific minimal safe criteria for personal care and home cleaning applications. 5. Publish work and support potential market introduction and roll out in open literature.

Jointly, the team will apply the following approaches: 1. Biomimicry Clues for Safer Solutions Nature provides multiple bioproducts that act to prevent microbial formation, including active oligosaccharides which prevent biofilm formation. Such areas will be explored deeper, including: Plant esters, diols, phenolics, chelates, terpenes, metals and polymer composites. 2. Screening Methods The team will develop ways to qualitatively screen target organisms quickly and safely through simple qualitative methods (mold- visual, bacteria- haze or other) and then an effort will be made to quantify results from preservative ingredients of highest interest. Results will be cross-compared versus results from the literature and from external lab results. 3. Toxicology, Healthy Solutions and Data base modeling Leverage available data base modeling to step up the broad based abilities to model both for optimum safe and effective targets.
