Jeff Seidling of Kimberly-Clark Corp. was next, and he described the development of a novel, soothing tissue incorporating phase-change materials. His presentation went through the steps of the development process, including how the ingredients were chosen and applied to this substrate. This technology also was recognized by Cosmetics & Toiletries as a finalist for the 2012 R&D Awards. Attendees were curious as to whether the specifications on raw materials for this application were tighter than typical, to which Seidling replied there was a specific “sweet spot” for the best results. Also, a question came up of whether the absorbency of the treated tissue was compromised, and Seidling replied, “It’s the same as for current tissues.” In a semi-rhetorical manner, Randy Wickett, PhD, of the University of Cincinnati, wondered, “How do you measure TEWL on the nose?”
In the final presentation of the event, Agisim spoke on a new approach to lip balm sunscreen formulation, focused on flavor. The goal of his team’s work was to develop a lip balm stick providing high UVA and UVB protection using a taste-masking technology to improve organoleptic properties. His solution applied multiple sunscreens with avobenzone and a sorbitol spider ester, sorbeth-2-hexaoleate, with a photostabilizer. Efficient taste-masking of the organic sunscreens was achieved by the spider ester when it was applied at approximately 0.6–2.0% w/w. Further, pre-mixing the ester with the sunscreens produces a complex that is stable at ambient temperatures but can be separated when heated to > 100°C. During the question/answer session, Kevin Tibbs of Better Life asked, “With use of the spider ester, did you look at the efficiency of the SPF?” Agisim responded, “There was no effect on UVA/UVB absorbance.”
In closing, Agisim and Dallal reminded attendees that “SCC means ‘Science Continues at the Company,’” and encouraged attendees to share what they learned when they return to the office, to encourage attendance as well as build upon the science presented. The last of the mid-year SCC Annual Scientific Seminars will be held in St. Louis, Mo., USA, on June 6–7, 2013. Since it is “the last hurrah,” strong attendance and participation are expected.
