Worked in Technology Development Group providing service to the Product Groups (Laundry, Household, Personal Care, and Specialty Products). Products include laundry and dishwashing detergents, deodorants, antiperspirants, depilatories, hard-surface cleaners, all-purpose stain removers, cat litter, and toothpastes. Worked both independently and directly with the Product Groups solve “emergency” problems, improve existing products, and develop novel products.Solved product stability problems including phase separation, syneresis, crystal growth, and formulation-container incompatibility.Determined of mechanism causing stability problems and development of accelerated stability methods to enable early detection of problems. Reformulated of existing products to reduce cost while maintaining performance.Reformulated of current products to improve product attributes such as performance, foam production, viscosity, ability to suspend insoluble particles while maintaining flow, and inclusion of enzymes.Developed of novel products including new forms of laundry detergents, dishwashing detergents, and hard-surface cleaners.Managed projects done by external collaborators.Member of teams with objective to propose, evaluate, and develop new products.

Invented and developed a foaming peractic acid sanitizer formulation (HRSTM) for vertical and irregular food-contact surfaces and direct-food (meat and produce) surfaces. Formulation exhibits increased biocidal efficacy due to high retention on surfaces. Collaborated with microbiology laboratory to evaluate efficacy and with marketing to establish cost-in-use and packaging. Participated in field trials.Developed odor-masked formulations containing concentrated peracetic acid sanitizer.Collaborated with Biopolymer Division for food and pharmaceutical applications.Emulsion and suspension stability (time and temperature) in soft drinks and nutritional beverages. Physical characterization to elucidate solution structure, thermal behavior and rheology.Technology development/evaluation for finding new applications of alginates, chitosan, and hyaluronic acid, as well as their chemically-modified derivatives.
