Oxidation-Activated Laundry Compounds for Moldy Malodor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing malodor counteracting technologies in laundry care articles often compromise the organoleptic properties of perfumes and fail to provide long-lasting odor substantivity, particularly in addressing moldy malodors.
Innovation Solution
Compounds of formulas (I), (II), (III), and (IV) release formate esters and alcohols upon oxidation, providing a long-lasting odor while counteracting malodors without affecting the organoleptic properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If malodor counteracting technology is applied to laundry care articles, then moldy malodors are eliminated and prevented, but the organoleptic properties of perfumes are compromised
Solution Approach 1:
The patent uses compounds of formulas (I)-(IV) as intermediary substances that release formate esters and alcohols upon oxidation. These intermediaries counteract moldy malodors through their decomposition products without directly interfering with perfume composition, thus resolving the contradiction between malodor elimination and organoleptic property preservation
Solution Approach 2:
The invention changes the chemical parameters of the malodor counteracting compounds by selecting specific molecular structures (formulas I-IV) that undergo oxidation to release beneficial formate esters and alcohols. This parameter change allows effective malodor counteraction while maintaining compatibility with perfume organoleptic properties
2Object-affected harmful factors
If existing malodor counteracting ingredients are used, then malodor perception is reduced, but long-lasting odor substantivity is not achieved
Solution Approach 1:
The patent applies preliminary action by incorporating compounds (I)-(IV) into laundry care articles before washing. These compounds are oxidized during the washing process to pre-form and release formate esters and alcohols that provide long-lasting odor substantivity, ensuring both malodor counteraction and prolonged fresh scent without requiring repeated application
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The compounds effectively eliminate and prevent moldy malodors, offering a substantive odor effect that persists over time without negatively impacting the sensory experience of laundry care products.
Implementation Method 1
the compounds of formula (I), (II), (III) and (IV) can advantageously be employed as a malodor counteracting technology/ingredient against moldy malodor while bringing a long-lasting or substantive odor from a given surface into the environment by releasing respectively a formate ester selected from the group consisting of a compound of formula (V), a compound of formula (VI), a compound of formula (VII) and a compound of formula (VIII) and/or an alcohol selected from the group consisting of a compound of formula (IX), a compound of formula (X), a compound of formula (XI) and a compound of formula (XII) together with para-methyacetophenone from a given surface into the surrounding environment upon exposure to an environment wherein they are oxidized
