Objective/Hypothesis: To demonstrate malodor reduction through fragrance design and physical malodor removal from the headspace using fragranced microcapsules in detergent. Methods Used: Sensory panels and instrumental headspace analysis. We developed sensory protocols for testing the complete malodor control technology solution in detergent vs. synthetic malodor & real malodor. Malodor reduction was demonstrated through relevant in use examples and analytical methods were utilized to show physical reduction of malodor. The topic of capsule suspension will also be covered as this is a challenge for liquid detergents.
Results: We obtained consumer perceivable malodor reduction in relevant real world applications with the product containing the fragrance microcapsules vs. product without the technology. The consumer perceivable benefit is also paired with instrumental headspace data, therefore proving physical malodor removal with technology. We were also successful with suspending capsules in a liquid detergent application in order to deliver the technology in this particular laundry application/.
Conclusions: Fragranced microcapsules are effective at reducing malodor in a laundry detergent and demonstrated in a real world application.
