Profragrance Composition with High LogP Ingredient for Laundry Tenacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current perfumery solutions, such as microcapsules and precursor compounds, fail to provide a long-lasting perfuming effect that lasts up to several days, as they either lack tenacity on laundry or have limited effectiveness after washing and drying.
Innovation Solution
A perfuming composition comprising at least one profragrance compound and one perfuming ingredient with a LogP value above 3, which releases perfume raw materials upon exposure to light, air, heat, moisture, or enzymes, providing a prolonged and intense fragrance effect comparable to or exceeding that of microcapsules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If profragrance compounds are used alone, then they contribute to slow release of perfume, but they do not reach the long lasting effect provided by microcapsules
Solution Approach 1:
The patent combines profragrance compounds with high LogP perfuming ingredients in a synergistic composition. The profragrance provides slow release through chemical reaction, while the high LogP ingredient ensures strong adhesion to laundry fibers. This merging of two different mechanisms achieves both prolonged duration and reliable tenacity that neither component could achieve alone.
Solution Approach 2:
The invention creates a composite perfuming system where profragrance compounds (which release perfume through chemical reactions triggered by O2, light, enzymes, water, or temperature) work together with perfuming ingredients having LogP above 3. This composite approach leverages the slow-release property of profragrances and the strong binding property of high LogP compounds to achieve long-lasting effects comparable to microencapsulation without using encapsulation technology.
2Duration of action of moving object
If microcapsules are used, then they provide long lasting perfuming effect, but they have complex device structure
Solution Approach 1:
The patent extracts and eliminates the microencapsulation component from the delivery system while retaining the desired long-lasting effect. By using profragrance compounds that release perfume through chemical reactions triggered by environmental factors (O2, light, enzymes, water, temperature), the invention achieves prolonged perfuming without the complex microcapsule structure, simplifying the overall system.
Solution Approach 2:
The profragrance compounds act as intermediaries that convert environmental triggers (O2, light, enzymes, water, temperature) into controlled perfume release. This intermediary mechanism replaces the physical containment and controlled rupture of microcapsules with a chemical reaction-based release system, achieving similar long-lasting effects through a different, simpler pathway.
3Ease of operation
If conventional perfuming ingredients are used, then they provide immediate fragrance impact, but they lack tenacity and do not remain on laundry when rinsed
Solution Approach 1:
The patent changes the key parameter of lipophilicity by selecting perfuming ingredients with LogP above 3. This parameter change increases the affinity of the perfume ingredients for the hydrophobic laundry fibers, dramatically improving tenacity and durability through rinsing. The high LogP value ensures strong adhesion while the profragrance component provides the prolonged release mechanism for sustained duration.
