Malodor counteracting compositions and method for their use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for counteracting malodors are inadequate in effectively neutralizing a wide variety of unpleasant odors, as they often rely on individual fragrance ingredients that do not synergistically combine to achieve enhanced malodor masking or neutralization.
Innovation Solution
The use of specific combinations of compounds from Group (I) and Group (II), including α-methyl-ionone, undecalactone, and citronellyl nitrile, which synergistically work together to efficiently mask and neutralize malodors from various sources, such as sweat, kitchen, and animal litter, by forming mixtures that provide a synergistic effect beyond the simple sum of individual contributions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual fragrance ingredients are used to counteract malodors, then the composition is simple, but the malodor neutralization effectiveness is insufficient
Solution Approach 1:
The patent combines multiple fragrance ingredients from different chemical families (terpenes, esters, aldehydes, ketones, nitriles) into a synergistic mixture. This merging of chemically diverse components creates a composition that neutralizes malodors more effectively than any single ingredient could achieve alone, directly resolving the contradiction between simplicity and effectiveness.
Solution Approach 2:
The invention creates a composite fragrance composition where ingredients with different chemical properties work together. The composite nature of the mixture, combining volatile and less volatile components, allows for both immediate and sustained malodor counteraction, achieving high reliability without requiring an overly complex formulation.
2Adaptability or versatility
If a wide variety of fragrance ingredients are combined to neutralize different malodors, then the malodor counteraction effectiveness improves, but the formulation complexity increases
Solution Approach 1:
The fragrance composition is designed with multi-functionality to counteract various types of malodors (body odor, food odors, environmental odors) simultaneously. The carefully selected combination of ingredients provides broad-spectrum malodor neutralization, making the composition adaptable to different applications without requiring separate formulations for each malodor type.
Solution Approach 2:
The patent optimizes the concentration parameters of each ingredient within specific ranges to achieve synergistic effects. By controlling the relative proportions of volatile and less volatile components, the formulation maintains versatility across different malodor types while managing formulation complexity through parameter optimization rather than unlimited ingredient combinations.
3Speed
If highly volatile ingredients are used for immediate malodor masking, then the initial effectiveness is high, but the duration of action is short
Solution Approach 1:
The composition dynamically transitions from immediate malodor masking provided by volatile ingredients to sustained counteraction by less volatile components. This dynamic structure ensures that as the volatile ingredients evaporate quickly to provide initial protection, the less volatile ingredients continue to release fragrance, maintaining malodor neutralization over an extended period.
Solution Approach 2:
The formulation includes less volatile ingredients that act as a reservoir, providing preliminary action that sustains the malodor counteraction after the volatile ingredients have dispersed. This preliminary presence of longer-lasting components ensures continuous protection without requiring frequent reapplication.

AI summary
The invention relates to a malodor counteractancy or counteracting (MOC) method that resorts to the use of specific malodor counteracting (MOC) mixtures of fragrance ingredients. More particularly, the invention relates to new MOC compositions capable of neutralizing or masking in an efficient manner malodors of a large variety of such as body or as malodors, kitchen malodors, toilet and bathroom malodors, and tobacco malodor. The novel MOC compositions of the invention contain at least one nitrile material in combination with another fragrance material and can be used in any finished consumer products such as air fresheners, kitchen or toilet/bathroom cleaning or freshening products, textile treatment products and products for application on the human skin or hair, or on animal fur, litter containers or cages.
